Student opportunities with Australian Wildlife Conservancy

8 09 2010

A colleague of mine, Dr. Matt Hayward of the Australian Wildlife Conservancy (AWC), asked me to circulate some Honours, MSc and PhD student project opportunities. I thought this would be best done by publishing the call as a blog post.

The AWC is a non-government, non-profit organisation dedicated to the conservation of Australia’s wildlife and their habitats. AWC’s south-east region has a team of 7 ecologists who work closely with the land managers to carry out AWC’s Conservation and Science Program. The Science Program includes strategic research designed to help us manage threatened species more effectively. Several of these research projects are suitable for Honours, Masters or PhD projects.

This prospectus provides an outline of the student projects that are currently on offer in the south-east region. The majority of the projects are based on one sanctuary, although some aspects of the research may be done on other AWC sanctuaries and/or government conservation areas.

AWC will partially support these projects with equipment, staff time and expertise, and accommodation. In some cases, AWC may also provide some vehicle use and office facilities onsite at The Scotia Field Research Centre. We anticipate these projects will be collaborative efforts with input from students, academics and AWC staff, with appropriate acknowledgement for all involved. These projects are offered on a first in, first approved basis and have been offered to multiple universities.

More details on the sanctuaries and AWC are available here. If you are keen do one of these projects, please contact Matt Hayward and we will then formulate a research proposal and research agreement. Eight project descriptions follow. Read the rest of this entry »

Long, deep and broad

24 08 2010

Thought that would get your attention ;-)

“More scientists need to be trained in quantitative synthesis, visualization and other software tools.” D. Peters (2010)

In fact, that is part of the title of today’s focus paper in Trends in Ecology and Evolution by D. Peters – Accessible ecology: synthesis of the long, deep,and broad.

As a ‘quantitative’ ecologist (modeller, numerate, etc.) whose career has been based to a large degree on the analysis of large ecological datasets, I am certainly singing Peters’ tune. However, it’s much deeper and more important than my career – good (long, deep, broad – see definitions below) ecological data are ESSENTIAL to avoid some of the worst ravages of biodiversity loss over the coming decades and centuries. Unfortunately, investment in long-term ecological studies is poor in most countries (Australia is no exception), and it’s not improving.

But why are long-term ecological data essential? Let’s take a notable example. Climate change (mainly temperature increases) measured over the last century or so (depending on the area) has been determined mainly through the analysis of long-term records. This, one of the world’s most important (yet sadly, not yet even remotely acted upon) issues today, derives from relatively simple long-term datasets. Another good example is the waning of the world’s forests (see posts here, here and here for examples) and our increasing political attention on what this means for human society. These trends can only be determined from long-term datasets.

For a long time the dirty word ‘monitoring’ was considered the bastion of the uncreative and amateur – ‘real’ scientists performed complicated experiments, whereas ‘monitoring’ was viewed mainly as a form of low-intellect showcasing to please someone somewhere that at least something was being done. I’ll admit, there are many monitoring programmes producing data that aren’t worth the paper their printed on (see a good discussion of this issue in ‘Monitoring does not always count‘), but I think the value of good monitoring data has been mostly vindicated. You see, many ecological systems are far too complex to manipulate easily, or are too broad and interactive to determine much with only a few years of data; only by examining over the ‘long’ term do patterns (and the effect of extremes) sometimes become clear.

But as you’ll see, it’s not just the ‘long’ that is required to determine which land- and sea-use decisions will be the best to minimise biodiversity loss – we also need the ‘deep’ and the ‘broad’. But first, the ‘long’. Read the rest of this entry »

100 actions to slow biodiversity loss

19 08 2010

I received an email a few days ago from Guillaume Chapron of the Swedish University of Agricultural Sciences (Sveriges lantbruksuniversitet) asking me to promote his ‘Biodiversity 100‘ campaign on ConservationBytes.com. I think it’s an interesting initiative, and so I’ll gladly spread the word.

Teaming up with George Monbiot of The Guardian, the Biodiversity 100 campaign seeks to encourage scientists and others to compile a list of 100 tasks that G20 governments should undertake to prove their commitment to tackling the biodiversity crisis.

Dr. Chapron writes: Read the rest of this entry »

Marine protected areas: do they work?

13 08 2010

“One measure that often meets great resistance from fishermen, but is beloved by conservationists, is the establishment of marine protected or ‘no take’ areas.” Stephen J. Hall (1998)

I’m going to qualify this particular post with a few disclaimers; first, I am not involved in the planning of any marine protected areas (henceforth referred to as ‘marine parks’) in Australia or elsewhere; and second, despite blogging on the issue, I have never published in the discipline of protected area design (i.e, ‘conservation planning’ is not my area of expertise).

That said, it seems to becoming more imperative that I enter the fray and assess not only how marine parks should be designed, but how effective they really are (or can be). I’ve been asked by several conservation NGOs to provide some insight into this, so I thought I should ‘think aloud’ and blog a little mini-review about marine park effectiveness.

Clearly there is a trend to establish more marine parks around the world, and this is mainly because marine conservation lags so far behind terrestrial conservation. Indeed, Spalding et al. (2008) showed that only 4.1 % of continental shelf areas are incorporated within marine parks, and ~ 50 % of all marine ecoregions have less than 1 % marine park coverage across the shelf. Furthermore, marine protection is greatest in the tropical realms, while temperate realms are still poorly represented.

The question of whether marine parks ‘work’ is, however, more complicated than it might first appear. When one asks this question, it is essential to define how the criteria for success are to be measured. Whether it’s biodiversity protection, fisheries production, recreational revenue, community acceptance/involvement or some combination of the above, your conclusion is likely to vary from place to place.

Other complications are, of course, that if you cannot ensure a marine park is adequately enforced (i.e., people don’t respect the rules) or if you don’t actually place the park anywhere near things that need protecting, there will be no real net benefit (for any of the above-mentioned interest groups). Furthermore, most marine parks these days have many different types of uses allowed in different zones (e.g., no fishing, some fishing, recreational diving only, no boat transport, some shipping, etc., etc., etc.), so it gets difficult to test for specific effects (it’s a bit like a cap-and-trade legislation for carbon – too many rules and often no real net reduction in carbon emissions – but that’s another story).

All these conditions aside, I think it’s a good idea to present what the real experts have been telling us about marine park effectiveness from a biodiversity and fishing perspective over the last decade or so. I’ll summarise some of the major papers here and give an overall assessment at the end. I do not contend that this list is even remotely comprehensive, but it does give a good cross-section of the available evidence. Read the rest of this entry »

General call for ConservationBytes.com contributions

10 08 2010

After just over two years running this blog, I’ve now built up a pretty good audience of conservation-interested people. The blog now has a monthly view rate of over 12,000 and >80 e-mail subscribers, so the material is being viewed far and wide. I want to thank all of you for your interest and comments.

It seems appropriate then to put out a general call for ConservationBytes.com contributions. I’ve had several guest posts now from students (Fishing for conservation, Make your conservation PhD relevant), postdocs (Coming to grips with the buffalo problem) and colleagues (Interview with a social [conservation] scientist, Put the bite back into biodiversity conservation), but these have come to me fairly haphazardly. I’d therefore like to invite short articles from the CB readership to expand the topics covered and provide a more interactive conservation discussion. Read the rest of this entry »

Tropical biology and conservation overview

28 07 2010

Last week I attended the 2010 International Meeting of the Association for Tropical Biology and Conservation (ATBC) in Sanur, Bali (Indonesia). I only managed one post on the real-world relevance of conservation research (that attracted quite a lot of comment) while there, but I did promise to give a conference overview as I did for the International Congress for Conservation Biology earlier this month. So here goes.

This was my first ATBC meeting despite having co-written ‘the book’ on tropical conservation biology (well, one of very, very many). I no longer live in the tropics but am still managing to keep my hand in many different aspects of tropical research. After all, tropical regions represent ground zero for conservation biology – they have the highest biodiversity (no matter which way you measure it), some of the greatest threats (e.g., most people, most rapid development, most corruption) and some of the most pressing human problems (disease, hunger, socio-political instability). Ironically, most of the world’s conservation ecologists work in temperate realms – it should really be the other way around. Read the rest of this entry »

Conservation research rarely equals conservation

21 07 2010

I am currently attending the 2010 International Meeting of the Association for Tropical Biology and Conservation (ATBC) in Sanur, Bali (Indonesia). As I did a few weeks ago at the ICCB in Canada, I’m tweeting and blogging my way through.

–

Yesterday I attended a talk by my good friend Trish Shanley (formerly of CIFOR) where she highlighted the disconnect between conservation research and actual conservation. I’ve posted about this before (see Out of touch, impractical and irrelevant & Make your conservation PhD relevant), but this was a sobering reminder of how conservation research can be a self-perpetuating phenomenon and often not touch the people who need it most.

Presenting the highlights of her paper published earlier this year in Biotropica entitled Out of the loop: why research rarely reaches policy makers and the public and what can be done, one comment she made during the talk that really caught my attention was the following (I’m paraphrasing, of course).

Most of the world’s poor living off the land are unconcerned about biodiversity per se. As conservationists we should not therefore adopt the typical preamble that biodiversity (e.g., forests) represent the “lungs of our planet” – what people (and especially women) need to know is how biodiversity loss affects “food for my children”.

The paper itself was an interview 268 researchers from 29 countries (of which I was one) about their views on the relevance of their work. Not surprisingly (but amazingly that we were so honest), most respondents stated that their principal target was other scientists, with policy makers and other marginalised groups/local people holding a distant second place. Corporate targets were also pretty rare – I guess we feel as a group that that’s generallly a lost cause.

Neither a surprise was that we generally view peer-reviewed scientific publications as the main vehicle for the dissemination of our results. What was a bit of a surprise though is that we fully admit papers aren’t the best way to trickle down the information (again, more of that brutal honesty); apparently we mainly believe ‘stakeholder meetings’

are more effective (I have my doubts).

Conservation Letters citation statistics

15 07 2010

As most CB readers will know, the ‘new’ (as of 2008) conservation journal kid on the block that I co-edit, Conservation Letters, was ISI-listed this year. This allows us to examine our citation statistics and make some informed guesses about the journal’s Impact Factor that should be ascribed next year. Here are some stats:

We published 31 articles in 5 issues in 2008, 37 articles in 6 issues in 2009, and so far 24 articles in 3 issues in 2010
Most authors were from the USA (53), followed by Australia (28), UK (29), Canada (10), France (7) and South Africa (4)
The published articles have received a total of 248 citations, with an average citation rate per article of 2.70
The journal’s h-index = 8 (8 articles have been cited at least 8 times)
The 31 articles published in 2008 have received thus far 180 citations (average of 5.81 citations per article)
The top 10 most cited articles are (in descending order): Read the rest of this entry »

Party with future conservation leaders

11 07 2010

I’ve just come back from the 2010 International Congress for Conservation Biology in Edmonton, Canada. I thought it would be good to tweet and blog my way through on topics that catch my attention. This is my third post from the conference, and a full conference ‘assessment’ post will follow in a few days.

—

I haven’t been a member of the Society for Conservation Biology for a very long time, and I’ve only now attended three annual meetings of the Society. I’ve been somewhat lukewarm about the social events at these conferences in the past, but this time I had much better experience.

After a less-than-inspiring barbecue meal and a general under-abundance of ethanol-based social lubricant, someone in our group whispered that we should ‘crash’ a party being held ‘secretly’ back at the conference venue. I had heard around the traps that the Conservation Leadership Programme (CLP) bashes were good, but I hadn’t attended one before. Well, not only was it a bloody good party, I’ve learned a little more about the programme and the kinds of people it promotes. Read the rest of this entry »

Put the bite back into biodiversity conservation

2 07 2010

Today’s guest post is by Dr. Euan Ritchie, formerly of James Cook University, but who is now firmly entrenched at Deakin University in Victoria as a new Lecturer in ecology. Euan’s exciting research over the course of his memorable PhD (under the tutelage of renowned ecologist-guru, Professor Chris Johnson) has produced some whoppingly high-impact research. This latest instalment highlights a series of related papers he and his colleagues have just produced. We’re fortunate he agreed to give us his thoughts. Interestingly, the topic was just highlighted in the last issue of Nature: Don’t damage dingos.

—

Corey has invited me to report on a recent paper published in Ecology Letters and another related study in PloS One, which together show how a better understanding of dingoes and their social structure and associated behaviour can help us to maintain or improve the health of our terrestrial ecosystems. This work, led by PhD student Arian Wallach (University of Adelaide), and involving collaborations with John Read (University of Adelaide), Adam O’Neill (C&A Environmental Services) and Christopher Johnson and me (James Cook University), offers some of the strongest evidence yet of the key roles top predators play in maintaining the balance.

Invasive species, along with habitat loss and the impacts of climate change, are among the greatest threats to the continued survival of many species. Because of this, millions of dollars and time is spent each year to control their populations. The impacts of invasive species in Australia are sadly all too obvious, with nearly half of the world’s mammal extinctions in the last 200 years occurring in Australia, with the prime suspects being the introduced domestic cat and red fox. However, despite massive, costly and ongoing attempts to control fox and cat populations successfully, we continue to witness the decline of many of our native species. Why? We would argue that the problem is that for too long much of our conservation and management efforts have been focused on treating symptoms and not the cause, which is the loss of ecosystem resilience (the natural ability of ecosystems to withstand change).

Interview with a social (conservation) scientist

22 06 2010

I was contacted recently by Josh Cinner, a self-titled ‘social’ scientist (now working at the Centre of Excellence for Coral Reef Studies) who has published rather a lot in the conservation literature. He was recently highlighted in the journal Science for his work, and he thought CB readers would enjoy the coverage. He stated to me:

“…as a social scientist, I have spent the past decade or so working with ecologists and managers trying to integrate social science better in conservation. There are often calls for the importance of integrating social science in conservation and I thought your blog readers might appreciate some high-level recognition of the importance of this. Additionally, as far as I can tell, this is the first of these profiles that has focused on someone working in conservation.”

So, while fully crediting the source of this article and its author, Helen Fields, here is the entire text reproduced for your reading pleasure.

In the late 1980s, things were not going well for the coral reefs at Jamaica’s Montego Bay Marine Park. Overfishing had taken out a lot of the fish that eat algae, and algae were taking over the reef. “It was a classic case of ecosystem decline,” human geographer Joshua Cinner says. He arrived in Jamaica in 1996 as a Peace Corps volunteer after graduating from the University of Colorado, Boulder, with a double major in environmental conservation and geography. He was particularly interested in parks and preserves.

He’d landed in the middle of a war. Lobbying by tour operators and others got spearfishing, one of the main culprits in overfishing, banned in the park. The ban did not go over well with local people. “All the park equipment got vandalized. We had park rangers get threatened; their families got threatened at spear point,” Cinner says. Spearfishing equipment is cheap and you don’t need a boat; men who do it are generally poor and are fishing as a last resort. “The cultural lens through which the fishermen viewed this issue was of struggle in a post-slavery society, of the rich, predominantly white expatriates making a law that oppressed the poorest of the poor locals to benefit the wealthy.”

The conflict got Cinner thinking about how conservation really works. “It wasn’t really about the ecology,” he says. “Making conservation work in Jamaica had a lot to do with understanding the local culture and people.” It also opened his eyes to the role oceans play. “The ocean is often viewed as an open-access resource. That extra layer of complexity interested me,” he says. “Land can often be private property,” but “the ocean is typically viewed as free for anyone to fish in, for anyone to swim in and use.” Read the rest of this entry »

ISI 2009 Impact Factors now out

18 06 2010

Last year I reported the 2008 ISI Impact Factors for some prominent conservation journals and a few other journals occasionally publishing conservation-related material. ISI just released the 2009 Impact Factors, so I’ll do the same again this year, and add some general ecology journals as well. For all you Australians, I also recently reported the ERA Journal Rankings.

So here are the 2009 Impact Factors for the journals listed on this site’s Journals page and their 2008 values for comparison: Read the rest of this entry »

Biodiversity SNAFU in Australia’s Jewel

16 06 2010

I’ve covered this sad state of affairs and one of Australia’s more notable biodiversity embarrassments over the last year (see Shocking continued loss of Australian mammals and Can we solve Australia’s mammal extinction crisis?), and now the most empirical demonstration of this is now published.

The biodiversity guru of Australia’s tropical north, John Woinarksi, has just published the definitive demonstration of the magnitude of mammal declines in Kakadu National Park (Australia’s largest national park, World Heritage Area, emblem of ‘co-management’ and supposed biodiversity and cultural jewel in Australia’s conservation crown). According to Woinarski and colleagues, most of those qualifiers are rubbish.

The paper published in Wildlife Research is entitled Monitoring indicates rapid and severe decline of native small mammals in Kakadu National Park, northern Australia and it concludes:

The native mammal fauna of Kakadu National Park is in rapid and severe decline. The cause(s) of this decline are not entirely clear, and may vary among species. The most plausible causes are too frequent fire, predation by feral cats and invasion by cane toads (affecting particularly one native mammal species).

I’ve done quite a bit of work in Kakadu myself, and the one thing that hits you every time you travel through it is the lack of visible wildlife. Sure, you’ll see horses, pigs and buffalo, as well as cane toads and cats, but getting a glimpse of anything native, from Conilurus to Varanus, and you’d consider yourself extremely lucky.

We’ve written a lot about the feral animal problem in Kakadu and even developed software tools to assist in density-reduction programmes. It doesn’t appear that anyone is listening.

Another gob-smacking vista you’ll get when travelling through Kakadu any time from April to December is that it’s either been burnt, actively burning or targeted for burning. They burn the shit out of the place every year. No wonder the native mammals are having such a hard time.

Combine all this with the dysfunctional management arrangement, and you cease to have a National Park. Kakadu is now a lifeless shell that does precious little for conservation of biodiversity (and 3 of the 5 criteria it had to satisfy to become a World Heritage Area are specifically related to natural resource ‘values’). I say, delist Kakadu now and let’s stop fooling ourselves.

Ok, back from the rant. Woinarski and others superimposed a mammal monitoring programme over top a fire-regime experiment for vegetation. Although they couldn’t sample every plot every season, they staggered the sampling to cover the area as best they could over the 13 years of monitoring (1996-2009). What they observed was staggering.

June 2010 Issue of Conservation Letters

9 06 2010

The third issue of Conservation Letters Volume 3 is now out. A good line-up of papers, indeed. Note that we’ve gone up to 9 papers in this issue, so keep the good submissions coming. Conservation Letters will most likely be listed on ISI Web of Science this year, and receive its first Impact Factor in 2011.

Thanks for the support.

How many species are there?

4 06 2010

An interesting research note just came out in the American Naturalist by Hamilton and colleagues entitled Quantifying uncertainty in estimation of tropical arthropod species richness. I retweeted a Science Daily twitter feed on this that had a terribly misleading opening line: “New calculations reveal that the number of species on Earth is likely to be in the order of several million rather than tens of millions“. This is, of course, absolute rubbish because the authors only looked at estimating tropical arthropod richness, not all species on Earth. The number of protists alone is probably > 4 million species, and there are an estimated > 1.5 fungi.

That whinge about crap reporting aside, this is what Hamilton and colleagues concluded:

using stochastic models, they predict medians of 3.7 million and 2.5 million tropical arthropod species globally
estimates of 30 million species or greater are predicted to have < 0.00001 probability
uncertainty in the proportion of canopy arthropod species that are beetles is the most influential parameter
in spite of 250 years of taxonomy and around 855000 species of arthropods already described, approximately 70 % await description

Interesting, but I didn’t give it much notice until New Scientist contacted me to get an assessment (their article will appear shortly). This is what I had to say: Read the rest of this entry »

Where in the world to invest in plant conservation

31 05 2010

It’s been a good few weeks with many of our papers coming out online early – for example, I highlighted one last week on ecosystem function breakdown from global warming.

Although this has been out for a few weeks, our new paper lead by PhD candidate Xingli Giam (formerly of National University of Singapore, recently completed Australian Endeavour Scholar, now at Princeton University and all-round up-and-coming research star), and with contributions from Hugh “Vascular” Tan and Navjot Sodhi of National University of Singapore and me, is entitled Future habitat loss and the conservation of plant biodiversity (just published online in Biological Conservation).

This one is a bit of a complicated one, so let me walk you through it.

Plants not only represent a huge component of global biodiversity (~320 000 species), they represent the ‘habitats’ in which animals live and provide the major source of nutrients to food webs. They also provide most of our food and other materials essential for human existence. Basically we’d be screwed without them.

Because so many of the world’s biomes are severely threatened now because of massive habitat loss, degradation, over-exploitation, invasive species, extinction synergies and climate change, we need to maximise our efficiency in protecting what’s left. While global prioritisation schemes have a fruitful scientific history since Myers & colleagues’ classic paper (see Biodiversity Hotspots), there are a number of problems that plague the concept and its implementation.

The planet is our bottle

22 05 2010

Professor Chris Thomas, conservation ecologist extraordinaire, tells it like it is. This might be a little basic for many ConservationBytes.com readers, but it’s the kind of pitch that might convince even the stupidest of yobs. I reproduce the Guardian article here in full.

Why do we care about nature, and can we actually quantify what the benefits are? This is what the UN’s The Economics of Ecosystems and Biodiversity (Teeb) project is all about, and the answer is remarkable. The natural world – biodiversity – provides us with food, materials and energy. We eat animals and plants; insects pollinate many of the foods we consume; microbes in the soil provide the nutrients the plants to grow; vegetation and soil biodiversity reduce flooding and release clean drinking water; vegetation soaks up a substantial proportion of the climate warming carbon dioxide gasses that we emit. The list goes on and on. Urban and rural citizens alike rely on these natural products and benefits.

The real cost of damaging nature, it turns out, is at least 10 times greater than the cost of maintaining the ecosystem as it is so that we can reap the associated benefits. To take an example close to the University of York where I work, the costs of flood defence construction and flood-related insurance claims in the Vale of York hugely outweigh the agricultural benefits of drainage ditches and overgrazing in the River Ouse catchment. Rather than treating nature as a pleasant luxury, Teeb argues that we should integrate the real costs and benefits within our decision-making. It should not be the preserve solely of environment and conservation ministries, but it should be at the core of the activities of finance departments. Teeb argues that we should get rid of subsidies that are environmentally damaging and reward beneficial activities that maintain natural ecosystems.
