You know it’s hot when it’s too hot to ….

My post’s title might be a good candidate title for a punk song in the 2030s (maybe by a re-incarnation of the Dead Kennedys).

I am currently sitting under my solar-powered ceiling fan as Adelaide is declared the world’s hottest city (and not in the funky, cultural, fun way), and I can’t help but contemplate climate change models predicting the fate of biodiversity over the coming decades. Because it’s far, far too hot to work outside, I’m perusing the latest interesting articles on the subject and I came across this recent little gem.

Also recommended on F1000Prime by Ary Hoffman, the paper, Using physiology to predict the responses of ants to climatic warming, by Sarah Diamond and colleagues touches on many aspects of climate predictions that need to be considered. I summarise these briefly here.

While no physiologist, I have dabbled in the past, although up until quite recently I didn’t see that physiology per se had much to do with conservation. It turns out that climate change has spawned an entire sub-discipline called ‘conservation physiology‘, which focuses inter alia on how species can/will/might respond and adapt to a warmer, climatically disrupted world.

What struck me about Diamond & colleagues’ paper was that yet again, it’s not as simple as heat-stressing a species experimentally and making a prediction on its future distribution (ecology is complex). No, the complexity comes in various forms that makes each species a little different from each other. Using North American ant species subjected to various warming scenarios in large (5 m) enclosures, they found the following: Read the rest of this entry »

Essential role of carnivores on the wane

This interesting review has just come out in Science, and because I was given a heads-up about it, I decided to do a F1000 recommendation. That’s more or less what follows, with some additional thoughts.

Ripple and colleagues can perhaps be excused for stating what might appear to many ‘in the biz’ to be blatantly obvious, but their in-depth review of the status of the world’s carnivores is a comprehensive overview of this essential guild’s worldwide plight. It not only represents an excellent teaching tool, the review elegantly summarises the current status of these essential ecosystem engineers.

The world’s 245 terrestrial carnivores might seem to be ecologically redundant to the informed given their natural rarity, low densities and cryptic behaviour, but nothing could be farther from the truth. Ecologists have only within the last decade or so revealed the essential ecosystem functions of these species (see former posts on CB.com here, here and here). The review focuses on the largest and most well-studied species, but the trends likely apply across most of the order. Read the rest of this entry »

More species = more resilience

8 01 2014

reef fishWhile still ostensibly ‘on leave’ (side note: Does any scientist really ever take a proper holiday? Perhaps a subject for a future blog post), I cannot resist the temptation to blog about our lab’s latest paper that just came online today. In particular, I am particularly proud of Dr Camille Mellin, lead author of the study and all-round kick-arse quantitative ecologist, who has outdone herself on this one.

Today’s subject is one I’ve touched on before, but to my knowledge, the relationship between ‘diversity’ (simply put, ‘more species’) and ecosystem resilience (i.e., resisting extinction) has never been demonstrated so elegantly. Not only is the study elegant (admission: I am a co-author and therefore my opinion is likely to be biased toward the positive), it demonstrates the biodiversity-stability hypothesis in a natural setting (not experimental) over a range of thousands of kilometres. Finally, there’s an interesting little twist at the end demonstrating yet again that ecology is more complex than rocket science.

Despite a legacy of debate, the so-called diversity-stability hypothesis is now a widely used rule of thumb, and its even implicit in most conservation planning tools (i.e., set aside areas with more species because we assume more is better). Why should ‘more’ be ‘better’? Well, when a lot of species are interacting and competing in an ecosystem, the ‘average’ interactions that any one species experiences are likely to be weaker than in a simpler, less diverse system. When there are a lot of different niches occupied by different species, we also expect different responses to environmental fluctuations among the community, meaning that some species inherently do better than others depending on the specific disturbance. Species-rich systems also tend to have more of what we call ‘functional redundancy‘, meaning that if one species providing an essential ecosystem function (e.g., like predation) goes extinct, there’s another, similar species ready to take its place.

King for a day – what conservation policies would you make?

29 11 2013

CrownI have been thinking a lot lately about poor governance and bad choices when it comes to biodiversity conservation policy. Perhaps its all that latent anger arising from blinkered, backward policies recently implemented by conservative state and national governments in Australia and elsewhere that leads me to contemplate: What would I do if I had the power to change policy?

While I am certain I have neither the experience or complete knowledge to balance national budgets, ensure prosperity and maintain the health of an entire country, I do have some ideas about what we’re doing wrong conservation-wise, and how we could potentially fix things. This is not meant to be an exhaustive list – it is more a discussion point where people can suggest their own ideas.

So here are 16 things I’d change or implement (mainly in Australia) if I were king for a day:

Ecologists: join F1000Research’s open science ecosystem

8 08 2013

f1000researchlogoThe people at the new open-access journal F1000Research (a Faculty of 1000 publication) have asked me to help them announce their new deal for ecologists – no processing fees until 2014! Might have to give it a go myself…

F1000Research covers all areas of life sciences, but we know that different fields each have their own unique characteristics, and some features of our journal are of particular interest to certain disciplines.

For the coming months, one area we’ll be focussing on is ecology. To encourage ecologists to try F1000Research, we’re waiving the article processing charge for all first submissions of an ecology paper until 2014. (Use code ECOL15 when submitting).

F1000Research is an ideal venue for publishing an ecology paper. Research, which includes full datasets, is openly available and its speed of publication and transparency in reviews makes it a refreshing alternative to traditional publishing.” Gary Luck, Institute for Land, Water and Society, Charles Sturt University, Australia

Three good reasons to send your ecology papers to F1000Research:

1.     Quickly reach a wide audience

All articles are fully open access and include all data, and with our post-publication peer review model, your article can be online within a week (find out more about our speedy publication process). Read the rest of this entry »

Ecology: the most important science of our times

12 07 2013

rocket-scienceThe title of this post is deliberately intended to be provocative, but stay with me – I do have an important point to make.

I’m sure most every scientist in almost any discipline feels that her or his particular knowledge quest is “the most important”. Admittedly, there are some branches of science that are more applied than others – I have yet to be convinced, for example, that string theory has an immediate human application, whereas medical science certainly does provide answers to useful questions regarding human health. But the passion for one’s own particular science discipline likely engenders a sort of tunnel vision about its intrinsic importance.

So it comes down to how one defines ‘important’. I’m not advocating in any way that application or practicality should be the only yardstick to ascertain importance. I think superficially impractical, ‘blue-skies’ theoretical endeavours are essential precursors to all so-called applied sciences. I’ll even go so far as to say that there is fundamentally no such thing as a completely unapplied science discipline or question. As I’ve said many times before, ‘science’ is a brick wall of evidence, where individual studies increase the strength of the wall to a point where we can call it a ‘theory’. Occasionally a study comes along and smashes the wall (paradigm shift), at which point we begin to build a new one. Read the rest of this entry »

Brave new green world: biodiversity’s response to Australia’s carbon economy

12 03 2013

carbon farming 2I’ve had a busy weekend entertaining visiting colleagues and participating in WOMADelaide‘s first-ever ‘The Planet Talks‘. If you haven’t heard of WOMADelaide, you’re truly missing out in one of the best music festivals going (and this is from a decidedly non-festival-going sort). Planet Talks this year was a bit of an experiment after the only partially successful Earth Station festival held last year (it was well-attended, but apparently wasn’t as financially successful as they had hoped). So this year they mixed a bit of science with a bit of music – hence ‘Planet Talks’. Paul Ehrlich was one of the star attractions, and I had the honour of going onstage with him yesterday to discuss a little bit about human population growth and sustainability. It was also great to see Robyn Williams again. All the Talks were packed out – indeed, I was surprised they were so popular, especially in the 39-degree heat. Rob Brookman, WOMADelaide’s founder and principal organiser, told me afterward that they’d definitely be doing it again.

But my post really isn’t about WOMADelaide or The Planet Talks (even though I got the bonus of meeting one of my favourite latin bands, Novalima, creators of one of my favourite songs). It’s instead about a paper I heralded last year that’s finally been accepted.

In early 2012 at the Terrestrial Ecosystem Research Network (TERN) symposium in Adelaide, the Australian Centre for Ecological Analysis and Synthesis (ACEAS) put on what they called the ‘Grand Challenges’ workshop. I really didn’t get the joke at the time, but apparently the ‘grand challenge’ was locking 30 scientists with completely different backgrounds in a room for two days to see if they could do anything other than argue and bullshit. Well, we rose to that challenge and produced something that I think is rather useful.

I therefore proudly introduce the paper entitled Brave new green world: consequences of a carbon economy for the conservation of Australian biodiversity just accepted in Biological Conservation. The online version isn’t quite ready yet (should be in the next few weeks), but you are welcome to request a preprint from me now. If you attended (the surprisingly excellent) TERN symposium in Canberra last month, you might have seen me give a brief synopsis of our results.

The paper is a rather  in-depth review of how we, 30 fire, animal, plant, soil, landscape, agricultural and freshwater biologists, believe Australia’s new carbon-influenced economy (i.e., carbon price) will impact the country’s biodiversity. Read the rest of this entry »

Hot topics in ecology

5 03 2013

HotTopic copyJust a short one today to highlight a new1 endeavour by the Ecological Society of Australia.

Ecological societies around the world (e.g., Ecological Society of Australia, British Ecological Society, Ecological Society of AmericaCzech Society for Ecology, Société française d’Écologie, etc. - see a fairly comprehensive list of ecological societies around the world here) are certainly worthwhile from an academic standpoint. I’m a member of at least three of them, and over the years I’ve found them to be a great way to meet colleagues to discuss various aspects of our work. The conferences are usually a lot of fun (although I’ve generally found the Ecological Society of America conferences are too huge and unwieldy to be terribly beneficial), the talks are usually pretty good, and the social programmes tend to demonstrate just how human we scientists can be (I’ll let you read into that what you want).

An outsider could easily argue, however, that most ecological societies are archaic bastions of a former time when ecology was more a theoretical endeavour for academic circles, with little of practical use in today’s society. I’d agree that many components of these societies still hold onto elements of this sentiment, but it’s fast becoming clear that ecological societies can play an immensely important role in shaping their countries’ environmental policy.

The biggest go first

11 12 2012

The saying “it isn’t rocket science” is a common cliché in English to state, rather sarcastically, that something isn’t that difficult (with the implication that the person complaining about it, well, shouldn’t). But I really think we should change the saying to “it isn’t ecology”, for ecology is perhaps one of the most complex disciplines in science (whereas rocket science is just ‘complicated’). One of our main goals is to predict how ecosystems will respond to change, yet what we’re trying to simplify when predicting is the interactions of millions of species and individuals, all responding to each other and to their outside environment. It becomes quickly evident that we’re dealing with a system of chaos. Rocket science is following recipes in comparison.

Because of this complexity, ecology is a discipline plagued by a lack of generalities. Few, if any, ecological laws exist. However, we do have an abundance of rules of thumb that mostly apply in most systems. I’ve written about a few of them here on ConservationBytes.com, such as the effect of habitat patch size on species diversity, the importance of predators for maintaining ecosystem stability, and that low genetic diversity doesn’t exactly help your chances of persisting. Another big one is, of course, that in an era of rapid change, big things tend to (but not always – there’s that lovely complexity again) drop off the perch before smaller things do.

The prevailing wisdom is that big species have slower life history rates (reproduction, age at first breeding, growth, etc.), and so cannot replace themselves fast enough when the pace of their environment’s change is too high. Small, rapidly reproducing species, on the other hand, can compensate for higher mortality rates and hold on (better) through the disturbance. Read the rest of this entry »

Arguing for scientific socialism in ecology funding

26 06 2012

What makes an ecologist ‘successful’? How do you measure ‘success’? We’d all like to believe that success is measured by our results’ transformation of ecological theory and practice – in a conservation sense, this would ultimately mean our work’s ability to prevent (or at least, slow down) extinctions.

Alas, we’re not that good at quantifying such successes, and if you use the global metric of species threats, deforestation, pollution, invasive species and habitat degradation, we’ve failed utterly.

So instead, we measure scientific ‘success’ via peer-reviewed publications, and the citations (essentially, scientific cross-referencing) that arise from these. These are blunt instruments, to be sure, but they are really the only real metrics we have. If you’re not being cited, no one is reading your work; and if no one is reading you’re work, your cleverness goes unnoticed and you help nothing and no one.

A paper I just read in the latest issue of Oikos goes some way to examine what makes a ‘successful’ ecologist (i.e., in terms of publications, citations and funding), and there are some very interesting results. Read the rest of this entry »

Sharks: the world’s custodians of fisheries

5 05 2012

Today’s post comes from Salvador Herrando-Pérez (who, incidentally, recently submitted his excellent PhD thesis).

Three species co-occurring in the Gulf of Mexico and involved in the trophic cascade examined by Myers et al. (8). [1] Black-tips (Carcharhinus limbatus) are pelagic sharks in warm and tropical waters worldwide; they reach < 3 m in length, 125 kg in weight, with a maximum longevity in the wild of ~ 12 years; a viviparous species, with females delivering up to 10 offspring per parturition. [2] The cownose ray (Rhinoptera bonasus) is a tropical species from the western Atlantic (USA to Brazil); up to 2 m wide, 50 kg in weight, and 18 years of age; gregarious, migratory and viviparous, with one single offspring per litter. [3] The bay scallop (Agropecten irradians) is a protandric (hermaphrodite) mollusc, with sperm being released a few days before the (> 1 million) eggs; commonly associated with seagrasses in the north-western Atlantic; shells can reach up to 10 cm and individuals live for < 2 years. In the photos, a black-tip angled in a bottom long-line off Alabama (USA), a school of cownose rays swimming along Fort Walton Beach (Florida, USA), and a bay scallop among fronds of turtle grass (Thalassia testudinum) off Hernando County (Florida, USA). Photos by Marcus Drymon, Dorothy Birch and Janessa Cobb, respectively.

The hips of John Travolta, the sword of Luke Skywalker, and the teeth of Jaws marked an era. I still get goose pimples with the movie soundtrack (bass, tuba, orchestra… silence) solemnizing each of the big shark’s attacks. The media and cinema have created the myth of man’s worst friend. This partly explains why shark fishing does not trigger the same societal rejection as the hunting of other colossuses such as whales or elephants. Some authors contend that we currently live in the sixth massive extinction event of planet Earth (1) 75 % of which is strongly driven by one species, humans, and characterized by the systematic disappearance of mega-animals in general (e.g., mammoths, Steller’s seacow), and predators in particular, e.g., sharks (2, 3).

The selective extirpation of apex predators, recently coined as ‘trophic downgrading’, is transforming habitat structure and species composition of many ecosystems worldwide (4). In the marine realm, over the last half a century, the main target of the world’s fisheries has turned from (oft-large body-sized) piscivorous to planctivorous fish and invertebrates, indicating that fishery fleets are exploiting a trophic level down to collapse, then harvesting the next lower trophic level (5-7).

Myers et al. (8) illustrate the problem with the fisheries of apex-predator sharks in the northeastern coast of the USA. Those Atlantic waters are rife with many species of shark (> 2 m), whose main prey are smaller chondrichthyans (skates, rays, catsharks, sharks), which in turn prey on bottom fishes and bivalves. Myers et al. (8) found that, over the last three decades, the abundance of seven species of large sharks declined by ~ 90 %, coinciding with the crash of a centenary fishery of bay scallops (Agropecten irradians). Conversely, the abundance of 12 smaller chondrichthyes increased dramatically over the same period of time. In particular, the cownose ray (Rhinoptera bonasus), the principal predator of bay scallops, might today exceed > 40 million individuals in some bays, and consume up to ~ 840,000 tonnes of scallops annually. The obvious hypothesis is that the reduction of apex sharks triggers the boom of small chondrichthyans, hence leading to the break-down of scallop stocks. Read the rest of this entry »

More is better

18 01 2012

In one of those rare moments of perusing the latest ecological literature, I stumbled across an absolute gem, and one that has huge conservation implications. Now, I’m really no expert in this particular area of ecology, but I dare say the paper I’m about to introduce should have been published in Nature or Science (I suspect it was submitted to at least one of these journals first). It was still published in an extremely high-impact journal in ecology though – the Journal of Ecology produced by the British Ecological Society (and one in which I too have had the honour of publishing an article).

Before I get into specifics, I have to say that one thing we conservation biologists tend to bang on about is that MORE SPECIES = BETTER, regardless of the ecosystem in question. We tend to value species richness as the gold standard of ecosystem ‘health’ and ‘resilience’, whether or not there is strong empirical evidence in support. It’s as if the more-is-better mantra strikes an intuitive chord and must, by all that’s ecologically right in the world, be true.

Of course, measuring what is ‘better’ is a difficult task, especially when we are talking about complex ecosystems comprising thousands, if not millions, of species. Does ‘better’ refer to the most temporally stable, the most genetically diverse, the most resilient to perturbation, or the provider of the greatest number of functions and hence, ecosystem services?

It’s up to you, but all these things tend to be difficult to measure for a large number of species and over time scales of sufficient duration to measure change. So the default for plants (i.e., the structural framework of almost all ecosystems) I guess has come down to a simpler measure of success – ‘productivity’. This essentially means how much biomass is produced per unit area/volume per time step. It’s not a great metric, but it’s probably one of the more readily quantifiable indices.

Enter the so-called ‘diversity-productivity relationship’, or ‘DPR’, which predicts that higher plant species diversity should engender higher net productivity (otherwise known as the ‘net biodiversity effect’). Read the rest of this entry »

Where the sick buffalo roam

28 10 2011

It’s been some time coming, but today I’m proud to announce a new paper of ours that has just come out in Journal of Applied Ecology. While not strictly a conservation paper, it does provide some novel tools for modelling populations of threatened species in ways not available before.

The Genesis

A few years ago, a few of us (Bob LacyPhil Miller and JP Pollak of Vortex fame, Barry Brook, and a few others) got together in a little room at the Brookfield Zoo in the suburban sprawl of Chicago to have a crack at some new modelling approaches the Vortex crew had recently designed. The original results were pleasing, so we had a follow-up meeting last year (thanks to a few generous Zoo benefactors) and added a few post-docs and students to the mix (Damien FordhamClive McMahon, Tom Prowse, Mike Watts, Michelle Verant). The great population modeller Resit Akçakaya also came along to assist and talk about linkages with RAMAS.

Out of that particular meeting a series of projects was spawned, and one of those has now been published online: Novel coupling of individual-based epidemiological and demographic models predicts realistic dynamics of tuberculosis in alien buffalo.

The Coupling

So what’s so novel about modelling disease in buffalo, and why would one care? Well, here’s the interesting part. The buffalo-tuberculosis example was a great way to examine just how well a new suite of models – and their command-centre module – predicted disease dynamics in a wild population. The individual-based population modelling software Vortex has been around for some time, and is now particularly powerful for predicting the extinction risk of small populations; the newest addition to the Vortex family, called Outbreak, is also an individual-based epidemiological model that allows a population of individuals exposed to a pathogen to progress over time (e.g., from susceptible, exposed, infectious, recovered/dead).

Life, death and Linneaus

9 07 2011

I’m sitting in the Brisbane airport contemplating how best to describe the last week. If you’ve been following my tweets, you’ll know that I’ve been sequestered in a room with 8 other academics trying to figure out the best ways to estimate the severity of the Anthropocene extinction crisis. Seems like a pretty straight forward task. We know biodiversity in general isn’t doing so well thanks to the 7 billion Homo sapiens on the planet (hence, the Anthropo prefix) - the question though is: how bad?

I blogged back in March that a group of us were awarded a fully funded series of workshops to address that question by the Australian Centre for Ecological Synthesis and Analysis (a Terrestrial Ecosystem Research Network facility based at the University of Queensland), and so I am essentially updating you on the progress of the first workshop.

Before I summarise our achievements (and achieve, we did), I just want to describe the venue. Instead of our standard, boring, windowless room in some non-descript building on campus, ACEAS Director, Associate Professor Alison Specht, had the brilliant idea of putting us out away from it all on a beautiful nature-conservation estate on the north coast of New South Wales.

What a beautiful place – Linneaus Estate is a 111-ha property just a few kilometres north of Lennox Head (about 30 minutes by car south of Byron Bay) whose mission is to provide a sustainable living area (for a very lucky few) while protecting and restoring some pretty amazing coastal habitat along an otherwise well-developed bit of Australian coastline. And yes, it’s named after Carl Linnaeus. Read the rest of this entry »

生态学 = ‘Ecology’ in China

13 05 2011

I’m just heading home after a very inspiring workshop organised by Fangliang He at Sun Yat-sen University in Guangzhou, China (I’m writing this from the Qantas Club in the Hong Kong airport).

Before I proceed to regale you with the salient details of the ‘International Symposium for Biodiversity and Theoretical Ecology‘, I am compelled to state publicly that I offer my sincerest condolences to Fangliang and his family; unfortunately Fangliang’s brother passed away while we were at the workshop and so Fangliang wasn’t able to spend much time reaping the fruits of his organisational labour. If you know Fangliang, please send him a supporting email.

That sad note aside, I am delighted to say that the workshop was compelling, challenging and also rather fortuitous. I was one of many overseas invitees, and I must say that I was at times overwhelmed by the size of the brains they managed to pack into the auditorium. Many colleagues I didn’t know attended, and I hope that many will become collaborators. The international invitees were: Read the rest of this entry »

How fast are we losing species anyway?

28 03 2011

© W. Laurance

I’ve indicated over the last few weeks on Twitter that a group of us were recently awarded funding from the Australian Centre for Ecological Synthesis and Analysis – ACEAS – (much like the US version of the same thing – NCEAS) to run a series of analytical workshops to estimate, with a little more precision and less bias than has been done previously, the extinction rates of today’s biota relative to deep-time extinctions.

So what’s the issue? The Earth’s impressive diversity of life has experienced at least five mass extinction events over geological time. Species’ extinctions have kept pace with evolution, with more than 99 % of all species that have ever existed now gone (Bradshaw & Brook 2009). Despite general consensus that biodiversity has entered the sixth mass extinction event because of human-driven degradation of the planet, estimated extinction rates remain highly imprecise (from 100s to 10000s times background rates). This arises partly because the total number of species is unknown for many groups, and most extinctions go unnoticed.

So how are we going to improve on our highly imprecise estimates? One way is to look at the species-area relationship (SAR), which to estimate extinction requires one to extrapolate back to the origin in taxon- and region-specific SARs (e.g., with a time series of deforestation, one can estimate how many species would have been lost if we know how species diversity changes in relation to habitat area).

When weeds are wanted

31 01 2011

And in keeping with the topic of bees

© Flowergardengirl

I’ve just read a very, very cool paper in Ecology Letters about something I’ve wanted to do myself for some time. It’s a fairly specific piece of work, so it could easily be reproduced elsewhere with different species. My point though is that a hell of a lot more of these types of studies are required.

The study by Carvalheiro and colleagues entitled Natural and within-farmland biodiversity enhances crop productivity examined the role of weedy (ruderal) vegetation in supporting pollinator communities. Using sunflowers as a model crop, they showed rather convincingly how native vegetation patches interspersed amongst crop species can enhance a host of crop production measures, even when larger areas of natural habitats were far away from the crops themselves.

Based on a series of plot experiments, they tested four main hypotheses:

  1. The distance to natural habitat affects pollination visitor abundance and diversity.
  2. Plots surrounding or interspersed with ruderal vegetation affect pollinator abundance and diversity.
  3. The diversity of pollinators visiting sunflowers affects honeybee (the principal pollinators) behaviour.
  4. The diversity of pollinators affects sunflower production.

Want a cool conservation job in beautiful southern Australia?

14 12 2010

I was asked to post this cool-sounding job on ConservationBytes.com – relevant punters welcome to respond.

Australian Wildlife Conservancy (AWC) is a non‐profit organisation dedicated to the conservation of Australia’s threatened wildlife and their habitats. AWC now owns and manages more land than any other private conservation organisation in Australia ‐  21 properties, covering more than 2.6 million hectares ‐ protecting more than 1,200 fauna species through active land management informed by strategic scientific research.

AWC is seeking an experienced and committed ecologist who will be pivotal in the development and implementation of the conservation and science program throughout south‐eastern Australia. The position will be based at Scotia Wildlife Sanctuary (where on‐site accommodation will be provided), but will include work at other AWC sanctuaries, especially Kalamurina (Lake Eyre), Buckaringa (Flinders Ranges), Yookamurra (Riverlands), Dakalanta (Eyre Peninsula), Bowra (Mulga Lands) and North Head (Sydney) sanctuaries.

Scotia is a large property (65,000 ha) that lies on the NSW‐SA border between Wentworth and Broken Hill, and includes Australia’s largest area free of foxes, cats and rabbits (8,000 ha) and where seven regionally extinct species have been reintroduced (bilby, boodie, woylie, bridled nailtail wallaby, numbat, greater stick‐nest rat, mala and black‐eared miner). In addition, the property has outstanding conservation values because it protects habitats, in good condition, that have been extensively cleared in western NSW.

History and future (of Australian ecology and society)

11 12 2010

I’ve just returned from a week-long conference in Canberra where the Ecological Society of Australia (of which I am a relatively new member) has just completed its impressive 50th anniversary conference. It was a long, but good week.

It’s almost a bit embarrassing that I’ve never attended an ESA1 conference before, but I think I waited for the right one. However, the main reason I attended was that I was fortunate to have received the ESA’s 3rd Australian Ecology Research Award (AERA), and the kick-back was a fully funded trip. My only reciprocation was to give a 40-minute plenary lecture – a small price to pay.

I entitled my talk ‘Heads in the desert sand: why Australians should wake up to the biodiversity crisis’, and I received a lot of good feedback. I talked about the global and Australian trends of biodiversity loss and associated ecosystem services, focussing the middle section on some of our work on feral animal ecology (see example). I then gave my views on the seriousness of our current situation and why some of the fastest losses of sensitive ecosystem services are happening right here, right now. I finished off with a section on how I think Australian ecologists could get more relevant and active in terms of research uptake by policy makers. I hope that the talk will be podcastable soon, so stay tuned.

But that was just ‘my’ bit. This post is more about a quick summary of the highlights and my overall impressions.
