A large number of marine mammals and birds have gone extinct in the last 200 years. It is also evident that other strictly marine species such as fishes and invertebrates are not as immune to extinction as previously thought (Carlton et al. 1999, Roberts & Hawkins 1999). The development of species-specific management plans that target potentially threatened marine species have lagged behind other management options, such as all-purpose marine reserves. Criteria for classifying marine species as “threatened” or “endangered” are particularly vague and there are no co-ordinated management strategies that are enacted once species are classified.

Marine species are considered potentially threatened, due to some combination of biological characteristics that make them naturally rare and human impacts that are likely to reduce their numbers even further. Species may be restricted to very small geographic areas that are highly disturbed. They may be over-exploited with no natural refuges from human exploitation. They may be restricted to shallow coastal areas and sensitive to coastal enrichment or pollution. They may be large, long-lived and susceptible to any level of exploitation or disease. They may be naturally weak competitors in the process of being replaced by exotic species. They may be specialised species that are sensitive to a widespread decline in the quality of their habitat. However, the particular problems faced by particular species are not always clear.

The main impediment to developing species-specific management strategies is that lack of information on the status of potentially threatened species or the ecosystems they rely on. That is, what is the geographic range of the species and what are the current population numbers and trends? What are the biological characteristics of species that should be considered potentially threatened? How are these species and their demographic parameters responding to exploitation, pollution, habitat loss and other disturbances? At what point should they be considered endangered? What management actions are possible and what are appropriate to species of different kinds?

The aim of this exercise is to assemble up-to-date information on the status of marine species that either have or should be considered potentially threatened. The species selected is the

Patagonian Toothfish.

REPORT

This is a written evaluation of the species. Your report should assess the current and projected status of this species and viable management options. You should:

• Review historic and current trends in the geographic range and abundance of the species (if available) and discuss whether these figures suggest that the species should be considered potentially threatened.

• Review the biological characteristics of the species and processes that have lead to the current status.

• Consider the current status of our scientific knowledge of this species and what are the research priorities?

• Outline the current status of the species, in terms of international and domestic legislation and conservation action.

• Outline species-specific management strategies that are appropriate for the conservation of this species.

• Discuss options for the active restoration of this species by captive breeding or enhancement.

• Give your prognosis for the future of this species.

Your report should be a maximum of
2500 words. It should begin with a title and should subsequently be divided into two sections: (1)
Executive Summary (maximum of
500 word summary of your main conclusions and a list of recommendations (suitable for forwarding to a newspaper); (2)
Technical Report (maximum of
2000 words, which is the main body of assignment, excluding figures and tables). To provide structure and clarity, the use of subheadings within the technical report is highly recommended, including an
introduction at the beginning (general concepts, background and a statement of the aims of the report) and a
conclusions and recommendations section at the end. All text should be written in your own words, giving the citations to articles or web sites from which the information was sourced. Do not copy from other assignments, past or present. Figures and tables can be either original or copied from published works or websites. Make sure copied figures are clear, provide an original caption and indicate the source. Reproduce photographs only where essential to illustrate a point.

1. ABOUT THIS SUBJECT

Marine Conservation Biology is a 3rd year BSc subject intended for students majoring in the fields

of marine biology, ecology, conservation biology or environmental impact assessment. It runs in

the second semester (July-November) and consists of 25 lectures and 12 tutorials that are a mix of

practical exercises, debates, discussions and presentations. Attendance at all tutorials is

compulsory and attendance at all lectures is highly recommended. To enter this subject you

should have completed Marine Biology to second year level. There are no inadmissible subject

combinations.

1.1 WHY MARINE CONSERVATION BIOLOGY?

So you have chosen to do Marine Conservation Biology! Congratulations on your wise choice.

There is an urgent need to focus science and research on conservation issues in the marine

environment. Many marine ecosystems are on the verge of collapse, many habitats have been

decimated and many believe we are on the threshold of a human-induced mass extinction event.

The mission of this subject is to develop scientific skills and enhance employment prospects to

confront the biodiversity crisis in the marine environment.

Conservation biology is the application of scientific methodology to the conservation of biological

diversity. It is an ecological science that targets the causes and seeks remedies to the disastrous

global decline in biodiversity that we have already seen on land and are beginning to see in our

harbours and oceans. Marine conservation biology is a relatively new and rapidly changing

discipline in marine biology. New concepts are developing, new hypotheses are being tested and

alternative views debated – all fuelled with a sense of urgency as evidence of the widespread

decimation of marine habitats and decline of marine species accumulates at an alarming rate.

We will start this subject with some of the general ideas on conservation and biodiversity that were

largely developed for terrestrial species and see which of these principles can be applied to marine

organisms. We will then examine new approaches that target threats to marine habitats and

species, with an emphasis on novel alternatives to terrestrial conservation practices. Both single

species and whole ecosystem approaches to marine conservation will be addressed. Particular

attention will be devoted to the effectiveness of marine reserves for biodiversity conservation and

the design of reserve networks. In addition, we will take a close look at the endangered species

concept and how it can be effectively applied to threatened marine

species.

For some species and habitats conservation may be too late. If the dire predictions concerning the

demise of seagrass beds, mangroves and coral reefs turn out to be correct, and if all the major

fisheries of the world continue to collapse at the same alarming rate, we will see the discipline

metamorphose from the principles of conservation (of what we have) to the restoration (of what we

had). To this end, this subject will culminate with a look at the emerging principles and practices of

rehabilitating severely impacted populations and habitats.

1.2 SUBJECT CONTENT:

This subject will take an ecological approach to human impacts on and conservation of marine

habitats and species, from a local (Australia), regional (South East Asia) and global (Planet Earth)

perspective.

• It will describe the ecological effects of overfishing, sedimentation and nutrient enrichment,

habitat loss, pollution, marine introductions and climate change.

5

• Case studies on the types and scales of human impacts on coral reefs, seagrass beds, kelp

forest and pelagic ecosystems will be examined.

• Sampling designs and ecological indicators will be developed for assessing the magnitude

and scale of impacts on marine habitats.

• Current practices employed in the conservation and management of marine habitats and

endangered marine species will be examined.

• A central focus will be on the ecological principles and practice of designing marine

reserves and determining how well they work.

• The subject will examine the meanings of the terms ‘rare’ and ‘endangered’ for marine

organisms, focussing on factors associated with the risk of extinction.

• Small population theory and conservation genetics will be discussed for large and/or highly

exploited marine organisms, including sharks, other large predatory fishes, reptiles, marine

birds and mammals.

• The final topic of interest will be restoration ecology – the principles and practice of

enhancing populations of rare species and restoring damaged biological communities.

• Tutorials will facilitate the debate of all current issues in marine

conservation.

1.3 LEARNING OBJECTIVES:

At the end of this subject, a student should have the ability to:

• Appraise the status of marine conservation biology and emerging theory.

• Assess the key threats to marine species and ecosystems, including overfishing, habitat

loss and fragmentation, pollution and climate change.

• Compare the effectiveness of different approaches for protecting marine biodiversity,

including the endangered species concept, marine reserves and integrated coastal zone

management.

• Examine the roles of population enhancement and habitat restoration in circumstances

where conservation efforts have failed.

• Practice methods to undertake literature searches and synthesize information on critical

issues in marine conservation and criticize published materials.

• Apply skills in environmental impact assessment and ecological surveys of tropical

organisms.

• Evaluate the status of potentially endangered marine species and formulate

management

plans.

• Demonstrate debating and presentation skills in evaluating controversies and knowledge in

marine conservation biology.

1.5 STRUCTURE OF THE SUBJECT

The basic structure of this subject is outlined below. While we will try to keep to this logical order in

the weekly schedule (section 2.2), occasionally lectures have to be swapped around to fit in guest

Plagiarism

Plagiarism is the act of taking and using another’s work as one’s own (including published works,

information from web sites and assignments by other students). It includes doing the following

without the due acknowledgment or clear indication of origin: directly copying any part of anyone

else’s work; using very close paraphrasing or summarising of another’s work; using or developing

an idea or thesis derived from another’s work; using the experimental results that have been

obtained by someone else.

Plagiarism is serious! Take special care not to copy from each other, from assignments submitted

in previous years or for other subjects, or from published works or websites. It is not allowable to

copy text, even if you cite the original document. Plagiarism may result in the offending piece of

assessment being rejected by markers and may lead to disciplinary action. To detect plagiarism,

10

electronic versions of your assignments will be scanned using software designed to detect

repeated tracts of text.

LECTURE 2: HISTORY OF CONSERVATION BIOLOGY AND ITS RELEVANCE TO THE

MARINE ENVIRONMENT

The purpose of this lecture will be to briefly review the history of terrestrial conservation biology

and evaluate whether or not terrestrial theory has any applicability to marine organisms. It

discusses why terrestrial models relating to reserve design and small population theory have

limited applicability to marine organisms. It suggests that marine conservation biology requires a

substantially different emphasis.

LECTURE 3: WHAT IS BIODIVERSITY AND HOW IS MARINE BIODIVERSITY THREATENED?

This lecture discusses the various meanings of the term biodiversity in an attempt to come to grips

with the fundamental goal of conservation biology. It discusses how we measure biodiversity, from

genes to ecosystems and evaluates current opinion as to the primary threats to biodiversity in

terrestrial environments. The threats to marine biodiversity are contrasted with terrestrial

environments. Key threats, including overfishing, nutrient enrichment, habitat destruction, marine

introductions and global warming are evaluated.

LECTURE 5: NUTRIENT ENRICHMENT – BOTTOM UP DESTRUCTION OF MARINE

ECOSYSTEMS

The seagrass decline represents the greatest loss of any single habitat in the sea. This lecture

documents the global decline in seagrass beds and the reasons for the decline, focussing on

nutrient enrichment and turbidity. The ecological consequences for other organisms dependent

upon seagrass are also discussed.

LECTURE 6: MARINE INTRODUCTIONS – DIVERSITY OF EFFECTS ON MARINE

ECOSYSTEMS

The accidental transfer of marine organisms by ships has reached epidemic proportions. This

lecture describes the ecological consequences of marine introductions, documenting the total

change of habitats in some harbours and estuaries. Potential methods for eliminating accidental

transport are discussed.

LECTURE 8: OCEAN ACIDIFICATION – THE NEXT BIG PROBLEM FOR CORAL REEFS

This lecture will outline the predicted effects of increasing CO2 on the pH of the ocean and

emerging information to suggest it will have a catastrophic effect on organisms with calcium

carbonate skeletons. Increasing evidence suggests fish sensory systems will also be disrupted.

Science 4:11-37.

LECTURE 9: MARINE ENVIRONMENTAL IMPACT ASSESSMENT

Developing models that reliably predict the ecological cost of human activities requires that we

build up an understanding of how these activities affect natural populations and communities.

Reliable models will enable us to forecast detrimental human impacts before they occur, minimize

effects as they occur and/or enhance recovery after they have occurred. To do this we need to: (1)

Distinguish effects on populations and communities from normal background variability; (2)

Measure and assess the spatial and temporal scales over which impacts and recovery may occur;

(3) Develop an understanding of the mechanisms that cause the effects. This lecture discusses

these issues.

Symposium, Panama 2:1479-1483

LECTURE 10: MARINE ORGANISMS AS ENVIRONMENTAL INDICATORS

“Indicator” species are “organisms which have certain characteristics making them suitable for

detecting and forecasting impacts at some level of biological organization, from biochemical to

ecosystem” (Soule & Kleppel 1988). A wide variety of criteria for the selection of ideal indicator

species have been advocated. The aims of this lecture are: (1) To critically examine the criteria for

the selection of indictor species; (2) Argue against the “shopping list” approach in favour of a

smaller number of criteria stemming from the practical limitations of sampling, and the ecological

and social importance of the species present in the community.

about monitoring the health of the largest barrier coral reef system in the world.

Reef over two decades, with implications for longer term-trends. Coral Reefs 30:521–531.

LECTURE 12: MARINE RESERVES: DO THEY WORK?

Marine reserves or marine protected areas (MPA’s) have become one of the major tools for the

management of coastal marine habitats and exploited marine organisms. They continue to be

established in the belief that they can protect a “representative” range of species and habitats,

where single-species approaches to marine conservation are doomed to fail. The first aim of this

lecture is to describe the ecological effects of marine reserves: (a) How do they affect the

abundance and structure of exploited populations, both within and outside protected areas?; (b)

What are the community-wide effects of marine reserves? Generalisations will be illustrated using

case studies on marine reserves from three different habitats: (i) Coral reefs; (ii) Temperate rocky

shores; and (iii) Temperate sub-tidal rocky reefs. The second question to consider is whether or

not the database strong enough to support the claims made for marine reserves.

LECTURE 13: MARINE RESERVE DESIGN: CHOOSING SITES, SIZES AND SPACING

Now that we know marine reserves work, the next obvious questions are: How big should they be?

What shape should they be? Where should they be? How many should there be? How should they

be arranged in space? Our goal in seeking answers to these questions is how to achieve

maximum protection for the greatest number of species. There has been considerable attention to

these questions in the design of nature reserves on land, although the theory has not often been

put into practice. We introduce WORLDMAP, a software package designed to trial different

selection strategies for maximizing biodiversity in reserves. The goal is to find a selection algorithm

that maximises the representation of species in marine reserves and provides the greatest

concordance among different taxa. We introduce a tutorial in which we compare

complementarity, diversity hot spot and endemicity hotspots for both fish and corals in Kimbe Bay,
Papua New Guinea. These approaches are contrasted with simple random selection of reserve
sites.

LECTURE 14: DO GREEN ZONES WORK? ASSESSING THE ECOLOGICAL EFFECTS OF

MANAGEMENT ZONING IN THE GREAT BARRIER REEF MARINE PARK

This lecture will examine the long-term effects of the rezoning of the Great Barrier Reef (GBR)

Marine Park in 2004, when 33% of the reef was protected in “no-take areas”. The effects of

reserve status on the abundance, biomass and reproductive potential of targeted marine fishes will

be addressed. It will examine the evidence for “fishery squeeze” (overfishing in response to

reducing the area for fishing) and the net effects of reserve status on fish abundance on the GBR.

The lecture will also examine effects of reserve status on the abundance of non-target species,

including overall fish community structure and coral cover. It will examine the evidence for

noncompliance or fishing in green zones by surveying lost or discarded fishing gear. Finally, it will

examine whether marine reserves can reduce the level of coral disease by minimizing mechanical

damage due to fishing.

LECTURE 15: MARINE RESERVES AND CONSERVATION IN THE PHILIPPINES

Dr Russ summarizes 20 years of research on the effectiveness of marine reserves in protecting

fish stocks at two heavily fished sites in the Philippines. He has recorded a continual increase in

fish biomass since the reserves were established and predicts populations may need to be

protected for 30-40 years before full recovery will be observed. Evidence for spill-over effects that

may enhance adjacent fished areas is presented. The need for inter-generational management

strategies is stressed.

LECTURE 16: LARVAL CONNECTIVITY AND THE DESIGN OF MARINE PROTECTED AREA

NETWORKS

An understanding of the degree of connectivity between marine populations is critical to

conservation, but remains unknown for the vast majority of marine organisms. The degree of larval

dispersal has implications for assessing the susceptibility of populations to overfishing, their ability

to recover, the spread of disease and so on. Critical design features for marine reserves, such as

reserve size and spacing, will ultimately be reliant on information on larval dispersal. This lecture

describes new approaches for assessing larval dispersal, including larval marking, otolith

microchemistry and new genetic techniques.

LECTURE 17: ENDANGERED SPECIES CONCEPT FOR THREATENED MARINE

ORGANISMS

The goal of this lecture is to discuss endangered species concepts and whether or not they can be

applied to the large majority of marine populations. The IUCN red-list categories are defined and

the data requirements discussed. We give a demonstration of RAMAS, a software package for

determining the status of potentially threatened marine species. Other characteristics of potentially

threatened marine species are discussed.

LECTURE 18: EXTINCTION, RESILIENCE AND THE CHARACTERISTICS OF MARINE

POPULATIONS

This lecture discusses the concepts of rarity and extinction for marine organisms. The relative

threats of global, local and ecological extinction are discussed. Different kinds of rarity are

described, including low local abundance and small geographic range. The lecture discusses why

many organisms are naturally rare and whether or not such organisms are endangered. Other

6

characteristics of marine populations that are relevant to their conservation organisms are

described.

LECTURE 19: RARITY AND EXTINCTION RISK IN CORAL REEF FISHES

In this lecture, we use published descriptions of species’ geographic ranges and abundances to

examine patterns of commonness and rarity among coral reef fish species. We then use these

patterns to test predictions generated by hypotheses of the causes of rarity. The specific questions

we have addressed are as follows: (1) What are the global patterns in the geographic ranges of

coral reef fishes?; (2) How do geographic ranges relate to location, latitude, body size, dispersal

ability and/or habitat specialization?; (3) Is there a positive relationship between geographic range

and abundance in coral reef fishes?; and (4) Does local abundance relate to body size or habitat

specialization?

LECTURE 20: SMALL POPULATION THEORY AND METAPOPULATION DYNAMICS

The purpose of small population theory is to provide, using simulations, sound quantitative

predictions about the likelihood of extinction under different conditions. If successful it can be

applied to the endangered species concept, providing an objective basis for placing species on

and taking them off endangered species lists. In this lecture I will consider the different kinds of

theoretical approaches used for determining population viability and whether or not these are

applicable to marine populations.

LECTURE 23: ENHANCEMENT OF MARINE POPULATIONS AS A CONSERVATION TOOL

This lecture describes the potential means to actively restore endangered marine populations. This

includes: (1) Release of hatchery produced larvae and juveniles; (2) Release of “wild” caught

larvae and juveniles; (3) Release of brood stock; (4) Recruit attractors and artificial habitats; (5)

Manipulation and restoration of natural habitat; and (6) Translocation of marine organisms within

and beyond historical range.

LECTURE 24: REVERSING HUMAN IMPACT: RESTORATION OF MARINE COMMUNITIES

When conservation fails to bring about return to the original habitat, “restoration” or “rehabilitation”

may be the only viable alternative. By restoration, we mean human intervention to rebuild or

accelerate re-growth of a habitat after a disturbance. It involves active manipulation of the

disturbed habitat to promote the necessary successional changes toward the “natural” state of the

community. We set out to accelerate a return to the original assemblage structure and/or

ecosystem function. Two questions will be addressed: (1) What ecological principles are relevant

to restoration?; That is, what are the rules that are appropriate to assembling a community?; and

(2) What are the necessary steps in a restoration program? This involves identifying the natural or

target condition for the habitat, developing the necessary technologies for restoring key species,

and assessing the success of the restoration program. This will be illustrated with a case study on

the restoration of a saltmarsh habitat.

4. POTENTIALLY THREATENED MARINE SPECIES: STATUS REPORTS

A large number of marine mammals and birds have gone extinct in the last 200 years. It is also

evident that other strictly marine species such as fishes and invertebrates are not as immune to

extinction as previously thought (Carlton et al. 1999, Roberts & Hawkins 1999). The development

of species-specific management plans that target potentially threatened marine species have

lagged behind other management options, such as all-purpose marine reserves. Criteria for

classifying marine species as “threatened” or “endangered” are particularly vague and there are no

co-ordinated management strategies that are enacted once species are classified.

Marine species are considered potentially threatened, due to some combination of biological

characteristics that make them naturally rare and human impacts that are likely to reduce their

numbers even further. Species may be restricted to very small geographic areas that are highly

disturbed. They may be over-exploited with no natural refuges from human exploitation. They may

be restricted to shallow coastal areas and sensitive to coastal enrichment or pollution. They may

be large, long-lived and susceptible to any level of exploitation or disease. They may be naturally

weak competitors in the process of being replaced by exotic species. They may be specialised

species that are sensitive to a widespread decline in the quality of their habitat. However, the

particular problems faced by particular species are not always clear.

The main impediment to developing species-specific management strategies is that lack of

information on the status of potentially threatened species or the ecosystems they rely on. That is,

what is the geographic range of the species and what are the current population numbers and

trends? What are the biological characteristics of species that should be considered potentially

threatened? How are these species and their demographic parameters responding to exploitation,

pollution, habitat loss and other disturbances? At what point should they be considered

endangered? What management actions are possible and what are appropriate to species of

different kinds?

The aim of this exercise is to assemble up-to-date information on the status of marine species that

either have or should be considered potentially threatened. The following list is a selection of

species (or groups of species) from a variety of taxa and geographic locations that either are or

might be considered endangered:

There will be a limit of just two students per species. There will be a sign-up sheet on LearnJCU

by the end of Week 2, so you can get started on your report as early in the semester as you’d like

to.

11

There will be two parts to this project:

4.1 STATUS

REPORT

This is a written evaluation of the species. Your report should assess the current and projected

status of this species and viable management options. You should:

• Review historic and current trends in the geographic range and abundance of the species

(if available) and discuss whether these figures suggest that the species should be

considered potentially threatened.

• Review the biological characteristics of the species and processes that have lead to the

current status.

• Consider the current status of our scientific knowledge of this species and what are the

research priorities?

• Outline the current status of the species, in terms of international and domestic legislation

and conservation action.

• Outline species-specific management strategies that are appropriate for the conservation of

this species.

• Discuss options for the active restoration of this species by captive breeding or

enhancement.

• Give your prognosis for the future of this species.

Your report should be a maximum of 2500 words. It should begin with a title and should

subsequently be divided into two sections: (1) Executive Summary (maximum of 500 word

summary of your main conclusions and a list of recommendations (suitable for forwarding to a

newspaper); (2) Technical Report (maximum of 2000 words, which is the main body of

assignment, excluding figures and tables). To provide structure and clarity, the use of subheadings

within the technical report is highly recommended, including an introduction at the beginning

(general concepts, background and a statement of the aims of the report) and a conclusions and

recommendations section at the end. All text should be written in your own words, giving the

citations to articles or web sites from which the information was sourced. Do not copy from other

assignments, past or present. Figures and tables can be either original or copied from published

works or websites. Make sure copied figures are clear, provide an original caption and indicate the

source. Reproduce photographs only where essential to illustrate a point.

Total 20.0

4.2 SEMINAR AND POSTER

You will need to prepare a poster using Microsoft PowerPoint (including pictures, maps, figures

etc) and present a 5 minute verbal presentation of the poster during tutorial time. Posters should

be in the form of a single slide, either in portrait or landscape mode. Please do not prepare a

powerpoint presentation with multiple slides and do not use animations. Posters will be projected

using a data projector, rather than printed (to save paper). Notes on how to prepare a poster can

be found in the next section.

13

A powerpoint file of your poster must be emailed to the relevant tutor 24 hours before your allotted

talk. An email will be sent to you to let you know who to send your poster to.

Make sure your last name and tutorial group is in the file name for the PowerPoint file when

it is emailed, e.g. Jones-Group1.pptx

Common faults with posters in previous years include:

(1) Writing in point form, with too little information. Use proper sentences.

(2) Poor balance between written and illustrative material, i.e. nearly all writing or nearly all

pictures. You need good use of both.

(3) Too much unused space – fill up the poster.

(4) Poor choice of background and font colours, so writing cannot be clearly seen.

(5) Lack of critical evaluation or synthesis.

(6) No clear conservation initiatives.

(7) Unimaginative title and layout.

(8) Not putting your name on the poster (or the ppt file).

Common faults with presentations include:

(1) Talking to the poster rather than the audience.

(2) Reading notes.

(3) Going well under or over the allotted 5 minutes.

(4) Giving a talk that does not integrate with the poster.

Hints on making a good poster

• There should be roughly equal amounts of written and illustrative material on your poster

• Use both graphs and pictures

• Use contrasting background and text colours

• Use a large enough font size for the text so that people sitting in the back of the room will

be able to read it

• Remember to put your name somewhere on the poster

• Save the PowerPoint file with your name and tutorial group as the filename

5. DISCUSSION TUTORIALS AND COMPUTER WORKSHOPS

5.1 TUTORIAL 1 (DISCUSSION TUTORIAL) – THE BIODIVERSITY DILEMMA: RESEARCH

AND MANAGEMENT OF RARE SPECIES OR ECOSYSTEMS (VERBAL DEBATE)

Conservation biology is concerned with developing methods for maintaining biodiversity. However,

biodiversity means different things to different people. To develop an all-encompassing definition,

Soule (1992) developed the idea of a bio-spatial hierarchy encompassing everything from genes to

landscapes. However, it is clear that there are insufficient resources to carry out all the required

research at all these levels. Since research and management at some levels may be more

effective than others, we need a set of research priorities.

Historically, the major focus of research, management strategies and funding priorities has been

on rare and endangered species, and this is likely to continue. Central to this approach are the

IUCN Red lists and “endangered species acts”, which have been adopted in many countries.

14

However, there has been an increasing call for research into maintaining ecosystem function (eg.

Franklin 1993). These workers believe that the species by species approach is inadequate and too

time consuming, and the extreme view is that individual species do not matter, provided

ecosystem function is maintained. They often point to the failure of endangered species acts to

save species from extinctions and argue that this legislation should be abandoned. However, the

alternative approach is not always clearly articulated and provides no guarantee that species will

not go extinct. For the marine environment, the single-species approach has primarily focussed on

mammals and reptiles, while ecosystem protection appears to primarily focus on marine reserves

and integrated coastal zone management.

In this tutorial we will debate whether or not our limited resources should go towards maintaining

threatened species (based on endangered species acts) or maintaining degraded ecosystems.

The latter approach argues for replacing endangered species lists and legislation with a

threatened ecosystem approach. But how do we define a threatened ecosystem? Regardless of

your personal views, if your surname starts with a letter between A-L, you should argue for

species, and M-Z, should argue for ecosystems. Would you argue the same for both marine and

terrestrial systems?

You will be split up into two groups for 20min to develop your arguments. Elect a scribe to make a

list of your key points. The two groups will then face-off to have the debate. The purpose of the

debate is to bring out the strengths and weaknesses of both approaches. Compromise will only be

allowed in the last 5 minutes.

5.2 TUTORIAL 2 (Literature Search) – CORAL REEFS IN CRISIS: OVER 50 YEARS

OF ESCALATING THREATS

5.2.1 Changing threats – changing research priorities

When scientists began studying coral reefs they were captivated by fundamental ecological issues

relating to their high biodiversity and productivity. Prior to the 1970’s it was relatively rare to find

publications on human impacts on coral reef habitats and there was little in the way of applied

research. With the first outbreak of crown-of-thorns starfish in the 1970’s, scientists began

focussing on the possible human causes (Grigg 1992). Increasing nutrient enrichment and

sedimentation on coral reefs lead to research programs focussing on the possible effects of

terrestrial run-off on coral reefs (Roberts 1993). Increasing exploitation of large reef fishes also

lead to scientists studying the impacts of exploitation on coral reef health (Roberts 1993). The

steady introduction of marine reserves highlighted the effects of exploitation and reserves as an

effective means of management. As time has progressed, an ever-increasing diversity of human

impacts has been documented. Over the last few decades, research on environmental issues on

coral reefs has grown dramatically, but the nature of this research has changed. By 2003,

scientists were ringing the alarm bells and the worldwide degradation of coral reefs is now widely

recognised (Hughes et al. 2004). The latest dire predictions for coral reefs come from global

warming and ocean acidification.

The aim of this tutorial is to conduct a literature search to document changes in the focus of coral

reef environmental research over the last 54 years. Is there evidence that scientists have

increased their attention to the environmental stresses faced by coral reefs? And have they shifted

their attention to different environmental issues as time has progressed? As an indicator of the

most important impacts on reefs, how many scientific papers have focussed on the different

threats facing coral reefs (e.g. crown-of-thorns outbreaks, nutrient enrichment, sedimentation,

exploitation, pollution, ocean warming, sea level rise, and acidification)? To date there has been

no integrated analysis of these trends.

There are fundamentally two ways to do research. One is to carry out primary research, which may

involve collecting your own data from the field. The other is to research the published scientific

database and analyse trends and generalizations from that source. This second approach is called

meta-analysis, which aims to compare and synthesize results from multiple studies. Meta-analyses

vary in sophistication from studies graphically examining trends in published data to complex

statistical analyses of research outcomes.

The aim of this exercise will be to carry out an online literature search to analyse trends in
the study of the environmental issues facing corals reefs and quantify how coral reef
scientists have risen to the challenge.

We will use a search engine, the ISI Web of Science, to examine trends in coral reefs science

between 1965 and 2018. This will allow us to systematically search the contents of key journals in

marine biology and ecology, and extract a data set that will enable us to answer the following

questions:

(1) Has the number of publications on human impacts on and conservation of coral reefs

increased over the last 54 years?

(2) Has the proportion of all publications on coral reefs that address environmental issues

increased over this period? That is, has there been a shift from pure to applied ecology?

16

(3) Over the last 54 years, how much research has been directed at the different environmental

issues? That is, what are the trends in the numbers of papers have focussed on (a) crown-

ofthorns starfish (Acanthaster) outbreaks; (b) terrestrial run-off (sedimentation, nutrient

enrichment); (c) chemical pollution and oil spills; (d) overfishing (live fish trade); (e) global warming

(coral bleaching, ocean warming, sea-level rise); (f) ocean acidification and (g) coral disease?

When did the first publications on each of these topics first appear? Is there just an overall

increase in the amount of research on all these impacts or have some perceived impacts come

and gone?

(4) Overall, how many studies have been published on the 6 different topics? What topics do

you think require more attention?

5.2.2 How to start?

There are potentially two ways to search the literature. One would be to laboriously thumb through

the pages of the journals. However, we are going to use the ISI Web of Science search engine,

which is going to be a LOT quicker. Each student will collect their own data by searching the ISI

Web of Science.

On the JCU website, click on Library, then click on Databases (from the menu bar below the

photo). Click W, then Web of Science. This will take you to the ISI Web of Knowledge web site.

Check that Web of Science Core Collection is selected and not All databases.

Under Timespan, select Custom year range, and set the year range to 1965-2018. We will not

search 2019 because it is not over yet!

Step 1. What is the total number of papers published on coral reefs? In the top topic field,

simply type coral* AND reef* (We add the “*” after the word “coral” so that in the search it will pick

up papers using both the singular and plural of that word).

Then press Search and it will display all papers including the word coral (or corals) and reef (or

reefs) between the dates requested. This will be the total number of papers on coral reefs,

including pure ecology and applied studies.

Press Analyze results (at the top right of the list of papers), and a new page will be displayed. In

the left-hand menu bar, select Publication Years. We do this to display results by year, from the

year with the most publications to the year with the least. Below the graph, change Show to 100,

make sure Minimum record count is set to 1, then click Update. Below this, you will see the

number publications by year from the maximum to the minimum.

Save the data as a text file and import it into Excel by clicking on Download (at the bottom right of

the page), and then Save File and OK. In Excel, click on File and select Open, select the text file

(it will be in the Downloads folder, unless you specified a different location when you saved the

file), make sure Delimited is selected and click Finish. Alternatively, open the text file in Web of

Science by clicking on Download, and then Open with and you can then copy and paste the data

into Excel. You cannot copy the data directly from ISI Web of Science and paste it into Excel as

Excel will treat the numbers as text and you will not be able to use them in any calculations.

17

To get back to the first page, click on Back to previous page (top left of page), then Search (top

left of page).

Step 2. How many publications have there been on crown-of-thorns starfish (Acanthaster)

and their impacts

on coral reefs?

Type in the following search algorithm in the top line (note: you need to type in the whole line

below, including

the AND and OR in capitals, and the *):

[Coral* AND reef* AND Acanthaster] OR [Coral* AND Reef* AND Crown* AND Thorn*]

This should pick up most of the papers on this topic. Click on Analyze results. Click on

Publication years, and check it is still set to show the top 100 results, and a minimum record

count of 1. Save the data to a text file and import it into your Excel file. You will need to rearrange

your data (using the Sort function in the Data tab) so that it is displayed in order of year, and insert

rows for any years that are missing.

Click on Back to previous page. To find examples of key papers on this topic, click on Create

citation report tab. This will arrange the papers from the most cited to least cited – the better

papers should be among the most cited. Make a note of some papers to cite in your report.

Step 3. How many publications have there been on sedimentation and nutrient enrichment

on coral reefs?

Type in the following search algorithm (note: you need to type in the whole line below, including

the AND and OR in capitals, and the *):

[Coral* AND reef* AND sedimentation] OR [Coral* AND Reef* AND nutrient AND enrichment] OR

[Coral* AND reef* AND terrestrial AND run-off]

Repeat the procedure above. Transfer the data to your Excel file.

Step 4. How many publications have there been on chemical pollution and oil spills?

[Coral* AND reef* AND chemical AND pollution] OR [Coral* AND Reef* AND oil AND spill*]

Repeat the procedure above. Transfer the data to your Excel file.

Step 5. How many publications have there been on overfishing or overharvesting on coral

reefs, including the effects of the live fish trade.

[Coral* AND reef* AND overfish*] OR [Coral* AND reef* AND overharvest*] OR [Coral* AND reef*

AND live AND trade]

Repeat the procedure above. Transfer the data to your Excel file.

Step 6 How many publications have there been on ocean warming, coral bleaching and sea

level rise.

[Coral* AND reef* AND ocean AND warming] OR [Coral* AND reef* AND bleaching] OR [Coral*

18

AND reef* AND sea AND rise]

Repeat the procedure above. Transfer the data to your Excel file.

Step 7. How many publications have there been on ocean acidification?

[Coral* AND reef* AND ocean AND acidification]

Repeat the procedure above. Transfer the data to your Excel file.

Step 8. How many publications have there been on coral disease?

[Coral* AND reef* AND disease]

Repeat the procedure above. Transfer the data to your Excel file.

5.2.3 Graphing your data and submitting your answer sheet

By the end of the tutorial, you should have an Excel spreadsheet with 9 columns – one column

with publication years, one column with the numbers of publications on coral reefs, and a column

each for the numbers of publications on the 7 human impacts. Graph your data to answer the

following questions:

(1) Has the number of publications on human impacts on and conservation of coral reefs

increased over the last 54 years?

To graph this, sum across the columns for the number of publications on the 7 human impacts

in each year. Plot this total number of papers (y-axis) against years (x-axis) using a line graph.

(2) Has the proportion of all publications on coral reefs that address environmental issues

increased over this period? That is, has there been a shift from pure to applied ecology?

To graph this, divide the values you calculated in question 1 by the number of studies on coral

reefs for each year. Graph this proportion (y-axis) against years (x-axis) using a line graph.

(3) Over the last 54 years, how much research has been directed at the different environmental
issues? That is, what are the trends in the numbers of papers have focussed on (a) crown-

ofthorns starfish (Acanthaster) outbreaks; (b) terrestrial run-off (sedimentation; nutrient

enrichment); (c) chemical pollution and oil spills; (d) overfishing (live fish trade); (e) global warming

(coral bleaching, ocean warming, sea-level rise); (f) ocean acidification; and (g) coral disease?

When did the first publications on each of these topics first appear? Is there just an overall
increase in the amount of research on all these impacts or have some perceived impacts come

and gone?

To graph this simply plot the numbers of studies on the seven topics (y-axis) against years

(xaxis), with a different line for each of the impacts. Make sure you label each line clearly.

(4) Overall, how many studies have been published on the 7 different topics? What topics do

you think require more attention?

To answer this, for each of the impacts, sum all the rows from 1965 to 2018. Plot a column graph

with the total number of publications (y-axis) and the seven different impacts (x-axis).

There is an answer sheet provided on LearnJCU in the folder ‘Lectures and Tutorials’ – ‘Week 3’.

Paste your graphs into the answer sheet and answer the questions, then submit your answer

sheet via the drop box in the Week 3 folder.

5.3 TUTORIAL 3 (DISCUSSION TUTORIAL) – “THE GLOBAL WARMING CONTROVERSY:

ADVOCATE OR SKEPTIC?” (VERBAL DEBATE)

The global warming controversy is a dispute regarding the nature and consequences of global

warming. Following the 5th Assessment Report of the Intergovernmental Panel on Climate

Change (IPCC) there is now broad scientific agreement that climate change is happening and is

very likely caused by human emissions of greenhouse gases. However, because of the

uncertainties in modelling climate change, there are still many skeptics. The aim of this tutorial will

be to debate and explore the arguments for and against human-induced climate change and

assess the merits of the arguments on both sides.

The key conclusion of the 5th IPCC report is that it is unequivocal that global warming is occurring;

it is ‘extremely likely’ that over half of the observed increase in global average surface temperature

from 1951 to 2010 was caused by anthropogenic emissions of greenhouse gases. Global mean

surface temperature has increased by 0.85 degrees Celsius from 1880 to 2012, and global mean

sea level has risen by 0.19 m from 1901 to 2010, and the frequency and intensity of extreme

weather events (e.g. floods, droughts, wildfires and cyclones) has increased. It is predicted that, by

the end of the 21st century (2080-2100) the following will occur: global mean surface temperature

will increase (relative to 1986-2005) by 0.3 to 1.7 degrees Celsius under the best (RCP2.6) of the

4 emissions scenarios, and by 2.6 to 4.8 degrees Celcius under the worst emissions scenario

(RCP8.5); global mean sea level will rise (relative to 1986-2005) by between 0.26 and 0.55 m

under the best emissions scenario (RCP2.6), and by between 0.45 and 0.82 m under the worst

emissions scenario (RCP8.5); and there will be an increase in the frequency of droughts, and in

the frequency and intensity of extreme weather events such as tropical cyclones (which include

typhoons and hurricanes).

The disputed issues include the causes of increased global average air temperature, especially

since the mid-20th century, whether this warming trend is unprecedented or within normal climatic

variations, and whether the increase is wholly or partially an artefact of poor measurements.

Additional disputes concern estimates of climate sensitivity, predictions of additional warming,

what the consequences are, and what action should be taken (if any). The debate is vigorous in

the popular media and on a policy level.

Before coming to the tutorial we will provide you with some articles to fuel the debate. At the

tutorial you will be randomly assigned to a position either for or against the conclusions of the

IPCC report. In the first half hour you will be divided into two groups to assemble your arguments,

after which we will have a class-level discussion.

5.4 TUTORIAL 4 (COMPUTER WORKSHOP) – MARINE RESERVES: DO THEY PROTECT

EXPLOITED SPECIES AND CORAL REEF HABITATS (VIDEO SURVEY EXERCISE)

5.4.1 Introduction

Marine reserves or marine protected areas (MPAs) have become one of the major tools for the

management of coastal marine habitats and exploited marine organisms (Lubchenco et al. 2003).

There are essentially two main types of MPAs (Hastings & Botsford 2003). The first and most

common is a “no-take” area that is specifically designed as a fishery management tool for

exploited species or multi-species assemblages (Gell & Roberts 2003). The second type of MPA is

a “conservation” area set aside for the protection of marine biodiversity (e.g., Fernandes et al.

2005). The evidence for local fishery benefits of MPAs is overwhelming, with the vast majority of

exploited species increasing in abundance, biomass and reproductive potential in no-take areas

(e.g., Gell & Roberts 2003, Russ 2003). The role of reserves in fisheries management has been

questioned, particularly for mobile species, where open areas become overfished or where there

are compliance problems (e.g., Agardy et al. 2003, McClanahan et al. 2006). However, while many

questions remain unanswered, such as the degree to which MPAs benefit adjacent fished areas

through larval connectivity (Sale et al. 2005), the case in support of the benefits of MPAs for

fisheries is overwhelming.

The degree to which MPAs benefit the vast majority of unexploited species is less clear. MPAs

continue to be established in the belief that they can protect a “representative” range of species

and habitats, promote biodiversity by protecting rare species or unique habitats, safeguard areas

in face of widespread habitat degradation, and contribute to recovery of damaged areas

(Lubchenco et al 2003). There is surprisingly little evidence for many of these claims. Many believe

MPAs are necessary, but by themselves insufficient to maintain marine biodiversity. There is little

doubt that closing representative of complementary areas is the most efficient way to include as

many species as possible in areas closed to fishing or collecting (e.g., Fox & Beckley 2006).

However, such species are only “protected” if you assume that fishing and collecting are the main

threats to these species. In coastal areas subject to terrestrial run-off, pollution or in the context of

global warming, MPAs may do little to prevent the decline of sensitive species (Boersma & Parrish

1999, Jones et al 2004, Cicin-Sain & Belfiore 2005). While MPAs may still increase the abundance

and biomass of exploited species in degraded habitats (e.g., Hawkins et al. 2006), they may do

little to halt degradation (Jones et al. 2004). The reduced fishing pressure and increase in the

abundance of large fishes in MPAs may itself be responsible for a decline in many smaller species

(e.g., Graham et al. 2003).

It is important that we consider whether or not marine reserves “work” in the way they are

intended. Not only can this tell us how we are impacting on marine assemblages (if indeed we

are), but it can also increase our understanding of how marine species respond to human

exploitation and to each other. Since some organisms increase in abundance in reserve areas,

and others may decline, we need to sample a range of organisms at different trophic levels to

determine whether MPAs are achieving the desired goals. While establishing marine reserves is

probably not going to be harmful if they do not work, if they do work, there can be no better

support than the biological knowledge that they are successful. Much of this information can be

gained from examining what goes on inside and outside marine reserves, before and after they are

established. They can be considered large-scale experiments in which we are learning a great

deal about how to manage and protect marine biodiversity.

22

The aim of this exercise is to examine the effects of a marine reserve network in Kimbe Bay,

Papua New Guinea on key coral reef organisms from different trophic levels, including corals,

algae, urchins and herbivorous fish. Many argue that maintaining healthy populations of herbivores

is crucial to maintaining reef biodiversity as a whole. GP Jones, along with a number of

collaborators, has been monitoring MPA’s (small reefs closed to fishing) and fished reefs in Kimbe

Bay since 1996 (MPAs established in 1999 – Jones et al. 2004). For this exercise, video transects

for benthic organisms and fishes were carried out in June 2006 for 3 of the MPAs and 3 reefs open

to fishing and collecting. Your task is to compare the cover or abundance of different organisms in

open and closed areas, and at the different sites, 7 years after protection.

5.4.2 Kimbe Bay, Papua New Guinea

Kimbe Bay is a large bay on the northern coast of New Britain, adjacent to the Bismarck Sea (Fig.

1). The small MPA network (Fig. 2) is located near two small villages not far from the township of

Kimbe, the commercial centre for West New Britain Province. Most of the fishing and collecting in

this area is at a subsistence level. Herbivorous fish are targeted with nets in shallow water

habitats. Local fishers also use “poison rope” (vines containing rotenone) to collect smaller fishes.

There is also intensive collecting of invertebrates such as beche-de-mer at low tide. Although there

is not complete compliance with the reserve status, fishing pressure is substantially reduced in the

MPAs. These reefs are also subject to coastal influences of sedimentation and nutrient enrichment

from deforestation and cultivation of oil palm, and from increased frequency of bleaching as a

result of ocean warming.

23

5.4.3 Sampling design

The goal is this exercise is to assess how a range of key organisms, including habitat formers

(e.g., corals, algae) and potentially important consumers (e.g., sea urchins, herbivorous fish) have

responded to protection. Video transects were recorded for 6 sites in total, three MPAs (Lady Di,

Limuka, Gava Gava) and three reefs open to fishing (Malane Huva, Garbuna, Luba Luba) in June

2006 (Fig. 2). Video footage is only provided for the shallow reef crest habitat, which is subject to

the greatest fishing pressure and also the greatest wave motion. Videos were made on snorkel,

sometimes in quite surgy conditions, so you should get a good feeling for the practical difficulties in

obtaining data in this habitat. You might even get seasick!

Fig. 2: Satellite image showing open and closed (MPA) reefs

Two types of video are provided on the Marine Conservation Biology YouTube channel:

(1) Benthic transects: There are 4 replicate 50m line transects (called Coral 1-4 on the DVD)

for each site. For these transects, the diver pointed the video camera downward and swam along

the transect line filming the substratum, keeping the transect line in view. These transects can be

used to record two things: (a) the % cover of the main attached organisms or substrate types, and

(b) the number of sea urchins Echinometra mathaei). You will need to play the coral transects

twice, once to record the substratum types, and a second time to count the sea urchins.

(2) Fish transects: There are also 5 replicate “timed swims” of 2 minutes each (called Fish 1-5

on the DVD) for each site. In these there is no transect line. The diver swam slowly along the edge

of the reef crest pointing the video camera straight ahead. These transects can be used to assess

the relative abundance of fishes in open and closed areas. Each person will record the numbers of

two herbivorous surgeonfish, Ctenochaetus striatus and Acanthurus lineatus. You will also need to

play each timed-swim twice, once to record each species.

On the MB3200 YouTube channel, there is a separate playlist for each site

Choose just 1 site and choose any 3 ‘Coral’ transects and any 3 ‘Fish’ timed swims to survey.

Record benthic substrata, numbers of sea urchins and numbers of the two fish species in the data

sheet provided, using the instructions below. Turn the volume off while playing the videos.

There are some photos of the organisms you will be recording on LearnJCU, so have a look at

these before you start.

5.4.4 Playing the videos and recording your data

(1) Benthic transects:

(a) In this exercise we will divide the substratum into 9 simple categories:

(1) Complex corals – branching, plate, digitate, foliose

(2) Massive, encrusting & solitary corals

(3) Soft corals, sponges, encrusting invertebrates

(4) Bare rock, coralline paint

(5) Turf algae on coral rock

(6) Turf algae on rubble

(7) Macroalgae

(8) Sand, gravel, or rubble.

(9) Others, including unidentified substrata.

The transect line has 100 random points marked with a black pen and numbered (1-100). Pause

the video when the random point is close to the middle of the screen and record the main

substratum underlying the point. Continue until you have recorded the substratum for all the

random points, marking the substratum on the data sheet provided as you go.

(b) Run each coral transect again to count the sea urchin Echinometra mathaei, including all

individuals seen on screen. Individuals of this species are very patchy and often deep in

grooves that they have created (see Figs. 10 and 11). You will need to be quite vigilant to see

them, and may need to pause or rewind the video to confirm their presence. Don’t be surprised

if you get none on some transects! To calculate urchin densities we will assume each transect

is 0.2m wide by 50m long (10m2).

(2) Fish transects:

Play each fish transect twice, once to count Ctenochaetus striatus (relatively common) and a

second time to count Acanthurus lineatus (relatively rare). Record your counts on the data sheet

provided. Fish are mobile and hard to see in the distance, which makes counting them difficult. It is

best to count them only when they come into the lower half of the screen where they are close

enough to identify. Count each individual only once. If a fish swims through your view and then

offscreen, and you see what you think is the same fish reappear, count this as a new individual.

Our counts of these two species will be expressed as mean numbers seen in 2 min of observation.

That is, they will not be expressed as a density or numbers per m2.

5.4.5 Class data set

Submit your data sheet via the drop box on LearnJCU (in the Week 5 folder) by the end of Week 5.

We will compile a class data set and upload this on LearnJCU (under ‘Assessment’) at the

beginning of Week 6.

5.5 TUTORIAL 5 (Information Session): HOW TO WRITE UP THE MARINE RESERVES

REPORT

In this tutorial we will run through how to graph, analyse and interpret your results. This is an

online tutorial, with a recording provided on LearnJCU for you to view in your own time, i.e. there is

no face-to-face tutorial in Week 6. There is also a screen recording on LearnJCU on how to

calculate means and standard errors, and plot graphs with custom error bars in Excel.

5.5.1 Graphing your data

You will need to download the Excel file containing the class data set from LearnJCU (in the folder

‘Assessment’ – ‘Assignment 1’). In this workbook there are three worksheets titled “Data Benthic”,

“Data Urchins” and “Data Fish”. In each sheet there is a data set that resembles the following

table,

and which provides you with the counts (fish, urchins) or percentage cover (benthic categories) in

each transect at each reef (represented by XYZ above). Remember that for benthic composition

and urchins there were four transects, but for fish there were five transects at each reef. You will

need to calculate and plot the mean for each variable (fish, urchins, benthos) for each reef. In

excel you can calculate the mean using the formula “ = average(D2:D5)”, for example, to calculate

the average of the values in cells D2 through D5. Once you have calculated the means you can

use these to create a chart.

You will also need to plot the standard errors on your chart of means. Standard error is the

standard deviation divided by the square root of the number of transects used to calculate the

mean. In Excel you can calculate the standard error for each mean using the formula “ =

stdev(D2:D5)/sqrt(4). Don’t forget to use sqrt(5) for the fish data. Those of you who have learned

how to use pivot tables in other courses can use this as an opportunity to practise your pivoting

skills! Once you have the standard errors you need to add them to your graph as custom error

bars.

Don’t forget to code your reefs as open or closed as well as providing their names. You should end

up with a figure for each fish species, urchins and for branching corals and the rock/algae category

(don’t worry about the other benthic categories) that roughly resemble the template provided

below.

5.5.2 Analysing your data

The data should be analysed for significant differences in the abundance of fish and urchins and in

the percentage cover of benthic categories using a two-level nested ANOVA, where Reefs are

nested in Open v Closed status. If you know how to perform this analysis you may carry out this

procedure yourself using the data provided. For those students who are unsure we have included

the following for your information.

In these analyses, Open v Closed status is a fixed factor, while Reef is a random factor. This is

because reefs can only be Open or Closed, there is no other option. In contrast, we chose six

reefs from a network of reefs, in which there were a number of other reefs we could have chosen,

therefore, they are random.

Our dependent variables in these analyses are each species of fish, urchins, and each benthic

category, and we need to do a separate ANOVA for each variable. For the two species of fish and

the urchins, testing of the assumptions of ANOVA revealed that the variances were heterogenous.

These can be greatly improved by a square-root transformation. Since the benthic categories were

percentage cover, we needed to do an arcsine transformation. Examples of how the ANOVAs

might look for the transformed data are as follows (your data will be different):

You will need to include your ANOVA results in your report either as Tables to which you refer in

the text e.g. “Mean abundances of Ctenochaetus striatus were approximately two to eight times

greater at closed reefs compared with open reefs in Kimbe Bay (Figure X) and this difference was

significant (Table X)”. If you do this don’t forget to create table headings to go under or above each

table, for example, “Table X. Two-level nested ANOVA for variation in abundance of Ctenochaetus

striatus according to reefs and open vs closed status”. Alternatively you can simply provide the

ANOVA results as follows (ANOVA: MS = 129.6, d.f. = 1, p = 0.019) when referring to differences

in Ctenochaetus abundance according to reserve status.

5.5.3 Writing your assignment

The report should be written as a short paper of 2,500 words, formatted for the journal

“Ecological Applications”. Get a copy of a recent paper from this journal and follow the format

as closely as possible. It should include a title, author, address, abstract, key words, introduction,

methods, results, discussion and literature cited. Each figure and table should be numbered and

have a clear legend that fully describes all axes and symbols. Do not use colour for a scientific

paper. Cite each figure and table in the text where it is first necessary.

TITLE: This should indicate the full scope of your study, while also being as succinct as possible.

ABSTRACT: In a single paragraph, briefly describe your aim, summarise all your main results and

highlight the significance of your findings. The major part of this paragraph should be your most

important results.

KEY WORDS: List 7-8 words that might be useful to index your work. You want to pick words that

would lead people to your paper in a literature search.

INTRODUCTION: This should not be more than 600 words and should not have subheadings. It

should start with general concepts, which highlight the need for your study. Refer to key papers to

make your case. Towards the end of the introduction you should address an overall aim, which

outlines the hypothesis or hypotheses being tested. For example, “The aim of this study was to

examine the hypothesis that the distribution and abundance of coral-dwelling gobies is determined

by the availability of preferred coral species”. This could be followed by a specific set of related

questions. At this stage you can introduce your study system and why it was selected to examine

these questions. All basic issues examined in the paper should be addressed in the introduction.

METHODS: State where and when the study was carried out, describe your sampling design(s)

and any analytical methods used. Use sub-headings where necessary. Include all methods that

are necessary to interpret the results in a logical sequence. Do not include methods that did not

work or no data is presented for. Do not include any results in this section.

29

RESULTS: Present your results in a logical sequence, again using sub-headings where

necessary. In each paragraph, describe the main result first, citing the appropriate figure or table.

E.g. “The abundance of Gobiodon micropus was strongly correlated with the abundance of

Acropora loripes (Fig. 1)”. It is not necessary to introduce figures. That is, statements like “The

relationship between Gobiodon micropus and Acropora loripes is shown in figure 1” are

unnecessary. Follow main points by bringing out results of lesser importance or giving more detail.

All figures and tables that are presented should be described in the text. Do not interpret or

discuss results in the results section or state why you did not get what you expected.

DISCUSSION: The discussion should begin by addressing your most important result and should

follow directly from your aim. For example, “This study confirmed that the distribution and

abundance of coral-dwelling gobies at Orpheus Island is largely determined by the abundance of

preferred corals” or “This study challenges the widely held generalisation that the distribution and

abundance of reef fishes is determined by habitat availability”. After this you could progress

towards findings of lesser importance. In each case, compare and contrast your findings to any

relevant published papers, without repeating your introduction. If your results conflict with the

literature, put forward alternative explanations for your results. Discuss how your study could be

extended to help resolve issues that arise from your preliminary findings. You should have a

concluding paragraph that highlights the significance of your contribution. You should not cite

figures and tables again in your discussion.

LITERATURE CITED: Follow the format of the journal. You should cite papers more broadly than

your particular study group. All papers in this list should be cited in the text and all papers cited in

the text should appear in this list.

5.6 TUTORIAL 6 (VIDEO PRESENTATION) – WHAT’S NEW IN MARINE CONSERVATION?

STORIES FROM HOME

The aim of this tutorial is for each student to research a current paper of their choice in marine

conservation. Pick a scientific paper (published between 2009 and 2019) based on a study from

your home Country, State or Town dealing with an interesting marine conservation issue. If you

have trouble finding a paper try searching on “Web of Science” and use keywords such as the

location and an issue you find interesting (e.g. overfishing). If you are from a land-locked country

or state, just choose a location that interests you!

Read and assess the paper, then make a 5-minute video recording of yourself giving a verbal

evaluation of the paper. Start your presentation by saying your name and where you are from. No

written assessment is required. The video can be made using your computer, hand-held video

camera or smartphone.

There is an MB3200 group on Facebook where you can post your video. You will receive an

invitation to join the group via email. Our Facebook group is a closed group, i.e. only members of

the group can see what has been posted to the group. When you post your video, be sure

to include the full reference for the paper.

5.7 TUTORIAL (COMPUTER WORKSHOP) – SELECTING SITES FOR MARINE RESERVES

USING WORLDMAP

5.7.1 Aims

1. Introduce WORLDMAP software for analysing patterns of species richness/ rarity

2. Examine the difference in efficacy of several reserve selection methods

3. Data management in WOLRDMAP and the concept of congruency

Imagine you have been asked to provide scientifically sound recommendations to prioritise 7 sites

for marine reserves in a bay in Papua New Guinea. The conservation goal is to protect the overall

biological diversity, in other words, include as many species as possible in the reserve network.

You have 35 reefs to choose from, with about 200 species of fish and 100 species of coral at each

site. The total number of species known is 888. How do you select the sites that will include the

most species?

Map of site locations in Kimbe Bay.

33

Site locations as they appear in WORLDMAP

We will run through some of the functions of the programme using a sample database of fish and
coral species at 35 sites at Kimbe Bay. We will use the example from the lecture to learn some of
the applications, and then you will analyse a new idea in part 2. You can also have a look at the
Worldmap – Demo programme, which is downloadable from the Natural History Museum website,
which is on your computer. It illustrates the world distribution of bumble bees of the Sibiricus group.

The basic data requirements of WORLDMAP are:

1. A map of a defined area (eg. Kimbe Bay in PNG)

2. A grid, that divides the region up into explicit units

3. A list of features (eg. Species or habitats) for each grid cell in the area.

Lets start!

34

5.7.2 Open World Map and view data

Click the windows icon at the bottom left of the screen, then click on the down arrow at the lower left
of the screen. This gives you a list of all the programs in alphabetical order and you will find World
Map under W. Click on World Map – Big Grid to open the program.

When World Map opens, you will get an Open datafile window with 1 file in it. Click on this file

(kb_all.dat) and click Open.

You will see a 10 X 20 grid, the top two on the left hand side (with coloured squares in them) contain
the data for sites in Kimbe Bay. You need to enlarge these two squares. To do this, click
MapGraphics -> ToggleZoom. The cursor changes into an arrow, which you can point and drag
around the area you want to display.

Look at the grid cells and the colours. This is a map showing total species richness (both fishes and
corals) in each grid cell. The scale bar showing the colour scheme is hidden on the right, but you
can view it by switching the toggle zoom off and on again.

Question 1: Patterns of species richness

Note where the hot and cold spots are. Note down which sites are the top 5 for species richness

of all species, their species number and percentage of total

richness.

Place the cursor on the grid cell you are interested in, and double click. A window will pop up,
displaying the site name, the percentage of total richness, a list of the species present at that site
and the number of species.

Question 2: Rare-threshold richness

Display richness of rare species below a certain threshold, i.e. species found only at a certain
number of sites. First, set the threshold value: click: AnalyticalTools -> Tool Options, then under
Hotspot Area Set, select richness for range sizes at or below 2 (see picture below), then press
OK (NB: 2 is the default – this displays the richness of species that are only present at one or two
sites).

35

To display rare-threshold richness, click AnalyticalTools –> Rarity -> Rare-threshold Richness.

Note the top 5 sites for rare species richness (species below threshold 2), the number of rare

species (number in each grid cell) and percentage of total

richness at each site.

To go back to the original map (showing total species richness), click: AnalyticalTools ->

Diversity -> Richness

To view rare-threshold richness again, click: AnalyticalTools -> Rarity -> Rare-threshold

richness.

5.7.3 Display individual species

Worldmap allows you to display each species separately, which is useful if you are interested in

finding out which sites a particular species is found at.

Question 3: display individual species

Display Rare-threshold richness (Analytical tools -> Rarity -> Rare-threshold richness).

Part 1: Istigobius decoratus

– Double click on Numundo Island (orange grid cell at the lower left hand side of the map,

with 25 rare species).

– Tick Range-sizes to display the number of occurrences for each species. Find the goby
species, Istigobius decoratus (displayed as decoratus Istigobius in the window, 4th
species on the list) and double click on its name (don’t click on it once and then double click
as it won’t work) to display the sites where it occurs. The sites that this species is found at
will be displayed (green circles). Look at the map on the previous page to work out the type
of habitat this species prefers (i.e. sheltered reefs/exposed reefs/anywhere).

– Double-click on each green circle to get the name of each site, and the total species

richness at each site.

Part 2: Lutjanus kasmira

– Repeat this procedure for a 2nd species (display the Rare-threshold richness first). Double

click on Wulai Reef (top of the furthest two right cells), then double click on kasmira

Lutjanus.

5.7.4 Data preselection

You can preselect data groups (e.g. different taxa or groups of species) from the database and
perform all operations on the selection. In this section we would like you to display total species
richness and rare-threshold richness (as in questions 1 and 2) separately for corals and fish.

Question 4: Species richness of corals

Click: DataBase -> Data preselection. This gives you a window with all the species in the database
listed. Each species has a code number (1 for Fish and 2 for Corals). To select corals, scroll down
the list of species and click on the first species with a “2”. The program automatically selects all
species with the group code 2. click OK. The map now shows coral species richness. Note the top
5 sites for total species richness of corals, their species number and percentage of total richness.

36

Question 5: Rare-threshold richness of corals

Display rare-threshold richness for corals (AnalyticalTools -> Rarity -> Rare-threshold richness).
Note the top 4 sites for rare species richness (threshold richness = 2), the number of rare species
(number in each grid cell) and percentage of total richness at each site.

Question 6: Species richness of fishes

Now preselect fish (DataBase -> Data preselection, click on a species with a “1”, then OK). Display
richness and note the top 5 sites for total species richness of fish, their species number and
percentage of total richness.

Question 7: Rare-threshold richness of fishes

Display rare-threshold richness for fish. Note the top 4 sites for rare species richness (threshold
richness = 2), the number of rare species (number in each grid cell) and percentage of total richness
at each site.

5.7.5 Site selection

Now we’d like you to select 7 marine reserve sites using three site selection methods (random,
hotspot and complementarity). Compare the 3 methods and work out which one gives you the
highest % of species. Before starting this section, make sure you de-select corals (Database ->
Data Preselection -> Restore Data -> OK), and display richness for all species (Analytical Tools
-> Diversity -> Richness).

Question 8: Marine reserve site selection Part

1: Random site selection

– To select the 7 sites randomly, click AnalyticalTools -> area selection -> random set
selection, type 7 into the box and click ‘Continue’, then click ‘Yes’ in the next window (titled
‘Select area sets at random’).

– To view the results, click MapGraphics -> Monitor RESULTS File.

– Note the cumulative % of species (“cum. %“ – this is the % of species included as each site

is added)

– Before you go on to the next site selection method, make sure you clear the list of sites

you’ve just selected (otherwise these sites will be left out of subsequent analyses). To do

this, double right click anywhere on the map. The ‘select grid cells’ window appears, click

Clear list, then Yes.

Part 2: Hotspot selection

– Click AnalyticalTools -> Area selection -> Hotspots (make sure the Tool Options are set

to “Richness” under Hotspots), then type in the number of sites you want and click

‘Continue’.

– Go to Map Graphics -> Monitor RESULTS to view the list of sites and cumulative % of

species.

– Don’t forget to clear the list of sites selected (see Part 1)

Part 3: Complementarity

37

– click: AnalyticalTools -> Area selection -> Greedy set. This gives each site a number,

according to the order in which they have been selected (i.e. 1 to 35).

– Go to Map Graphics -> Monitor RESULTS file to view the list of sites and cumulative % of

species. You will need to maximise the window to see the top few sites.

– Clear the list of sites.

5.7.6 Cross-taxa congruency

Worldmap allows you to overlay two layers to display the level of congruency of different taxa or
species groups, e.g. do sites with high coral diversity also have high fish diversity? High congruency
means that the best design for one taxa (e.g. corals) is also a good design for another (e.g. fishes).
You do this by displaying richness (or rare-threshold richness) for taxa on different maps and then
overlaying these to display the degree of overlap.

Question 9

– Preselect corals and display richness (as in section 5.6.4).

– Click MapGraphics -> Swap Scores. An empty map appears (the map for corals is in the

background).

– Now preselect fish and display richness.

– Click MapGraphics -> Overlay Scores. Choose the default settings. A window will appear
with the Spearman Rank correlation parameters (Question 7.), and a map. A significant
result means that site rankings for fish are correlated with site rankings for corals (i.e. sites
with high fish diversity also have high coral diversity).

– Check out Restorff Island (the lower white square) for details by double-clicking it.

5.9 TUTORIAL 9 (COMPUTER WORKSHOP) – CLASSIFYING THREATENED MARINE

SPECIES USING RAMAS REDLIST

5.9.1 An Overview of RAMAS Red List

RAMAS Red List is software from Applied Biomathematics that implements IUCN threatened

species criteria (IUCN 2001), which are rules for assigning species into categories representing

different level of threat. The IUCN rules are based on information about such characteristics as

number and distribution of individuals, fluctuations and decline in abundance and distribution, and

risk of extinction. These characteristics are used as input data; the output is a classification into

one of the categories, such as Critically Endangered, Endangered, Vulnerable, or Least Concern.

RAMAS Red List implements these rules as used by the IUCN, but also allows explicitly

incorporating uncertainties in the input data. In other words, input data such as the number of

mature individuals can be specified either as a number, or as a range of numbers, or a range of

numbers plus a best estimate. RAMAS Red List propagates these uncertainties (see Uncertainty

propagation). Depending on the uncertainties, the resulting classification is often a single category,

accompanied by a range of plausible categories.

RAMAS Red List is now recommended software for assessors evaluating species for the IUCN

Red List Programme (through appointed Red List authorities).

5.9.2 IUCN Red List Categories

The threatened species categories developed by the IUCN are used in Red Data Books and Red

Lists. These categories are widely recognized internationally, and they are now used in a whole

range of publications and listings, produced by IUCN as well as by numerous governmental and

non-governmental organizations. The Red Data Book categories provide an easily and widely

understood method for highlighting those species under higher extinction risk, so as to focus

attention on conservation measures designed to protect them.

The categories are:

Extinct

Extinct in the Wild

Critically

Endangered

Endangered

Vulnerable

Near Threatened

Least Concern

Data Deficient

In 2000, the IUCN Council approved revisions to the categories, their definitions, and criteria for

assigning taxa to categories.

5.9.3 How to operate the software

Step 1: Getting into the program

Click the windows icon at the bottom left of the screen, then click on the down arrow at the lower left
of the screen. This gives you a list of all the programs in alphabetical order and you will find RAMAS
RedList under R. Click on RedList 2.0 to open the program.

Step 2: Examine data for terrestrial species.

Click on the File menu, and select “Open”. Click on one of the files in the list to open it. This will

open the file in a Taxon window. At the top and bottom of this window are two series of tabs. The

bottom tabs are Data, Results, and Options. Check out the results for 2 or 3 different terrestrial

species first (I suggest Californian Condor and Coyote).

The input data are specified in the Data tab. If it is not selected, you can select this tab by clicking

on it, or

by pressing Alt-D. The tabs at the top of the window will be:

General

Contact Ecology Population Reduction Extent and Area Fragmentation Risk

These correspond to major groups of input data. Click on each tab, and inspect the input data. For

information about a parameter, press F1 while the cursor is in the edit box for that parameter.

To the right of each edit box is a button (a box with three dots in it). Clicking on this button opens

the value editor, which displays the input value numerically and graphically, and gives the units

and other attributes. See value editor (numbers) for entering or editing a number, or value editor

(logical values) for entering or editing a logical value.

Next, click on the Results tab in the bottom of the Taxon window (or, press Alt-R). The tabs at the

top of the window will be:

Status Contribution Text results

The Status result gives the classification of the taxon into one or more of the categories

Least concern Vulnerable Endangered

Critical (critically endangered).

If the input data are uncertain, the taxon may be classified into a range of categories. If the range

includes a Vulnerable, but the most plausible category is Least concern, the taxon is classified as

Near threatened. If the input data are not sufficient to make a classification, the taxon may be

identified to be “data deficient”.

The Contribution result gives the contribution of the 5 IUCN criteria (A to E) to the threatened

status of the taxon.

The top graph shows the classification when all available data are used. This is the same graph as

in the Status result. The second set of 5 graphs shows the classification when each of the 5

43

criteria is not used in the calculation. The third set of 5 graphs shows the classification when only

one of the 5 criteria is used.

The Text results allow you to follow the calculations of the program step-by-step. These

calculations follow the IUCN criteria, and they are carried out for each of the three categories,

Critical, Endangered and Vulnerable.

Step 3: Entering new data to RAMAS Red List

On a separate spreadsheet we have given you some data for 10 different marine species.

The aim of this exercise is to evaluate whether there is sufficient data to classify these

species using the IUCN categories, and if so, what are the recommended categories. Enter

the species name and all relevant information, and leave boxes blank or unchecked if the

information does not exist.

To start entering data for a new taxon, select New from the File menu (or, press Ctrl-N). At the top

and bottom of this window are two series of tabs. The bottom tabs are Data, Results, and Options.

The input data are specified in the Data tab. If it is not selected, select this tab by clicking on it, or

by pressing Alt-D. The tabs at the top of the window will be:

General Contact Ecology Population Reduction Extent and Area Fragmentation Risk

These correspond to major groups of input data. For each of these groups, you can enter Notes

(optional).

General: Make sure you enter the species and genus, as well as the generation time (life span) if

known.

Contact: Make sure you enter your name here.

Ecology: You can leave this section out for the purposes of the lab.

Population: Enter number of mature individuals (if known). Enter number of individuals 3

generations ago, or projected for 3 generations in future.

Reduction: Enter estimates for % population decline over last 3 generations or projected decline

for next 3 generations.

Extent and area: Enter geographic range (extent of occurrence) and area of occupancy (area

occupied within geographic range).

Fragmentation: Enter number of subpopulations.

Risk: Don’t worry about this one….

When there is a range of values for a particular parameter, you can enter the range, e.g. if

population size is 100-1000, you would enter [100, 1000]. You can also enter a best estimate and

a plausible range, e.g. [70, 90, 120].

44

To save the data you have entered, first make sure that the window that has the data you

want to save is the active window, and then select “Save As” under the File menu. You

should only save your data onto your own USB drive. Enter a filename as the genus and

species. The file type (extension) should be “.red”. The file will include the all the data,

comments, notes, references, etc. that you have entered in the Data windows.

Step 4: Viewing your results

The results of the calculations are summarized in the following 5 windows, which can be accessed

by clicking on the Result tab at the bottom of the Taxon window.

Status is the summary of results; it gives the classification of the taxon into a threat category, and

(depending on uncertainties) a range of plausible categories. In most cases, the listing criteria are

also given. If there are warnings, they will be listed at the end.

Contribution gives the contribution of the 5 IUCN criteria (A to E) to the threat status of the taxon.

Step 5: Comparing all marine species

At the end of the lab we will ask you to fill out a form with the recommended status for all 10

species. Overall, which species were critically endangered, endangered and vulnerable? How

many species were data deficient? Was there a difference among mammals, birds and fishes in

the criteria used to classify species? Do you think this program is generally useful for marine

species?
