Help us restore a forest

12 04 2013

plantingI’m not usually one to promote conservation volunteer opportunities, but this is a little different. First, I’m involved in this one, and second, it’s very near to my home. As you might know, the Mount Lofty Ranges area has had about 90 % of its forests destroyed since European settlement, with a corresponding loss of ecosystem services. We need smart restoration on massive scale, and Monarto is one place where we can develop the best practices to achieve this goal. We really do need some help here, so I encourage anyone in the Adelaide area with an interest in evidence-based forest restoration to lend us a hand.

The Monarto Restoration Project will provide an internationally recognised opportunity to experience and engage with wild Australia as it was.

Our aim is restore and expand habitats at Monarto to represent what used to exist in the region before clearing for agriculture and the introduction of pest species. Monarto used to be teeming with wildlife. The remnant vegetation at Monarto is unique as it is located at the cross-over of two vegetation communities (the Mt Lofty Ranges and Murray Mallee). This means it provides important habitat for a range of threatened bird and plant species. However, there are still a number of species in danger of being lost from the area, so we need to focus on restoring habitat to support them too.

We provide an opportunity to see the bush in a way that is no longer possible in most parts of Australia. We hope to help you see what we have lost and encourage you to participate in conservation. It gives us the opportunity to include everyone in on-ground conservation work and pass on skills that can be applied beyond a day or this project. With your help we can reduce the impacts of pest species on the property and re-introduce some of the native species that are now locally extinct. Read the rest of this entry »

Today we announced a HEAP of positions in our Global Ecology Lab for hot-shot, up-and-coming ecologists. If you think you’ve got what it takes, I encourage you to apply. The positions are all financed by the Australian Research Council from grants that Barry Brook, Phill Cassey, Damien Fordham and I have all been awarded in the last few years. We decided to do a bulk advertisement so that we maximise the opportunity for good science talent out there.

We’re looking for bright, mathematically adept people in palaeo-ecology, wildlife population modelling, disease modelling, climate change modelling and species distribution modelling.

The positions are self explanatory, but if you want more information, just follow the links and contacts given below. For my own selfish interests, I provide a little more detail for two of the positions for which I’m directly responsible – but please have a look at the lot.

Good luck!

Science immortalised in cartoon

1 02 2013

Well, this is a first for me (us).

I’ve never had a paper of ours turned into a cartoon. The illustrious and brilliant ‘First Dog on the Moon‘ (a.k.a. Andrew Marlton) who is chief cartoonist for Australia’s irreverent ‘Crikey‘ online news magazine just parodied our Journal of Animal Ecology paper No need for disease: testing extinction hypotheses for the thylacine using multispecies metamodels that I wrote about a last month here on ConservationBytes.com.

Needless to say, I’m chuffed as a chuffed thing.

Enjoy!

Degraded States of Ausmerica

20 08 2012

You might remember that I’ve been in California for several weeks now. The principal reason for my visit was to finish a book that Paul Ehrlich and I started last year. So, without the major distractions of everyday university life, I’ve spent much of my time lately at Stanford University in a little office next to Paul’s trying to finish (I also attended a conference in Portland, Oregon).

Yesterday, we wrote the last few paragraphs. A giant gorilla has now lumbered its way off my back.

So. What is the book about, you might ask? I can’t give away too many details, but I will give a few teasers. The book is called, at least for now, ‘Oz & US’, which is a bit of a play of words. In the book we contrast the environmental histories, current state of affairs, and likely futures of our respective nations. It’s written in a popular style so that non-specialists can learn a little something about how bad the environment has become in our two countries.

At first glance, one might wonder why we chose to contrast the U.S. and Australia – they are quite different beasts, indeed. Their histories are immensely different, from the aboriginal populations, through to European colonisation (timing and drivers), biological (including agricultural) productivities, carrying capacities, population sizes and politics. But these differences belie too many convergences in the environmental states of each nation – we now both have increasingly degraded environments, we have both pushed the boundaries of our carrying capacities, and our environmental politics are in a shambles. In other words, despite having started with completely different conditions, our toll on nature’s life-support systems is now remarkably similar.

And anyone who knows Paul and me will appreciate that the book is completely irreverent. We have taken off the gloves in preparation for a bare-knuckle fight with the plutocrats and theocrats now threatening the lives of our grandchildren. We pull no punches here. Read the rest of this entry »

Sustainable kangaroo harvests

10 11 2011

When I first started this blog back in 2008, I extolled the conservation virtues of eating kangaroos over cattle and sheep. Now I want to put my academic money where my mouth is, and do some kangaroo harvest research.

Thanks to the South Australia Department of Environment and Natural Resources  (DENR) and the commercial kangaroo harvest industry, in conjunction with the University of Adelaide, I’m pleased to announce a new scholarship for a PhD candidate to work on a project entitled Optimal survey and harvest models for South Australian macropods based at the University of Adelaide’s School of Earth and Environmental Sciences.

DENR is custodian of a long-term macropod database derived from the State’s management of the commercial kangaroo harvest industry. The dataset entails aerial survey data for most of the State from 1978 to present, annual population estimates, quotas and harvests for three species: red kangaroo (Macropus rufus), western grey kangaroo (Macropus fuliginosus), and the euro (Macropus robustus erubescens).

Big sharks. Big mystery.

9 03 2011

My PhD student, Ana Sequeira, has just written a great little guest blog post for the Environment Institute‘s blog. Given I’m en route to Tasmania for a quick consultancy meeting, I thought I’d let myself off the hook and reproduce the post here. Well done, Ana (and hint to my other students – your time on ConservationBytes.com is coming…).

This week is Seaweek and guest blogger Ana Sequeira describes how whale shark distribution might be shifting according to seasonal environmental predictors.

Ana Sequeira is a PhD student at the University of Adelaide (Global Ecology Group). Her main research interests are to develop models applied to the marine environment to describe key environmental processes, species distribution patterns and ecological interactions.

The main objective of her PhD thesis is to investigate behavioural ecology of whale sharks. She is now trying to understand which environmental variables may affect whale shark distribution.

The whale shark (Rhincodon typus, Smith 1828) is the largest fish in the ocean and can reach more than 12 m in total length. Although little is known about their habitat selection or migration patterns, the whale shark appears to be a highly mobile species. They predictably form near shore aggregations in some coastal locations (e.g. off Ningaloo reef in Western Australia) what makes them the subject of highly lucrative marine ecotourism industries. Also, artisanal and small-scale fisheries for the species still exist in many parts of the tropics.

Since the whale sharks is classified a Vulnerable species (IUCN Red List), understanding their migratory behaviour became of chief importance as they can be travelling from regions where they are protected to regions where they are still harvested. Read the rest of this entry »

The Amazing Paul (Mc)Ehrlich

15 11 2010

© CJA Bradshaw

A few years ago when I first wrote about Paul Ehrlich in our book, Tropical Conservation Biology, I quickly became impressed. His track record is, without any exaggeration, truly awe-inspiring. With over 1000 articles published and almost 50 books, the man has been a scientific writing machine for his entire career. He’s also highly influential in the socio-political sphere, and counts among his close friends some of the most politically and scientifically powerful people on the planet. In a word, he’s easily among the world’s greatest living scientists.

Remember, this was my opinion all before I actually met the man. Travelling through central California last year, I was lucky enough to be invited by Paul’s close colleague, Gretchen Daily, to give a talk at their Stanford University lab. It was fortunate that Paul was about at the time and not off promoting his new book or traipsing through the mountains of Colorado chasing butterflies.

We hit it off immediately and it seemed became mates within the space of a few hours. I learnt then that he and his equally famous wife, Anne, were regular visitors to Australia and that he had a particular love affair going with many Australian wines. I invited him to come to Adelaide the following year, he agreed (and importantly, so did the director of the Environment Institute, Mike Young), and it came to pass. Read the rest of this entry »

More rain forest regeneration opportunities

5 10 2010

Last November I wrote about an exciting conservation research endeavour (see ‘How to restore a tropical rain forest‘)  in which I am involved called the Thiaki Rain Forest Regeneration Project taking place as we speak in the hinterland of north Queensland’s Atherton Tableland. I personally have done next to nothing on the project yet (UQ’s Margie Mayfield is leading the charge), so I can’t really update you on all the nitty-gritty of our progress. Regardless, I can say that some of the planting tests have been done, the species have been chosen and are growing happily in the nursery reading for planting in January 2011, and the baseline biodiversity assessments are well under way.

Well, prior to our Supercharge Your Science extravaganza in Cairns and Townsville a few weeks ago, I visited Penny & Noel at Thiaki for a catch up, a discussion of what’s been happening and what’s about to happen. It was a great weekend (the family came along too) with good food, wine, ticks and leeches (biodiversity in action), and I’m getting more and more excited about what this project will deliver over the coming years.

In the meantime, a couple of ‘opportunities’ have arisen; in other words – we need some good PhD students to tackle some outstanding issues with the project. Read the rest of this entry »

Global erosion of ecosystem services

14 09 2010

A few months ago I was asked to give a lecture about erosion of ecosystem services to students in the University of Adelaide‘s Issues in Sustainable Environments unit. I gave that lecture last week and just uploaded a slidecast of the presentation (with audio) today.

I’ve reproduced the lecture here for your viewing pleasure. I hope you find the 45-minute presentation useful. Note that the first few minutes cover me referring to the Biodiversity film short that I posted not too long ago.

Webinar: Modelling water and life

27 08 2010

Another quick one today just to show the webinar of my recent 10-minute ‘Four in 40’ talk sponsored by The Environment Institute and the Department for Water. This seminar series was entitled ‘Modelling as a Tool for Decision Support’ held at the Auditorium, Royal Institution Australia (RiAus).

“Four in 40″ is a collaboration between The University of Adelaide and the Department for Water, where 4 speakers each speak for 10 minutes on their research and its implications for policy. The purpose is to build understanding of how best to work with each other, build new business for both organisations and raise awareness of activity being undertaken in water/natural resource management policy and research.

Conservation jobs at the University of Adelaide

13 04 2010

I’m posting the advertisements for two new conservation jobs in the Global Ecology Group at the University of Adelaide.

This Australian Research Council-funded Discovery Project seeks to determine whether functional forms of spatially explicit population dynamics are generalisable across taxa with similar attributes and range limiting factors. By considering the effects of multiple interacting factors (biotic and abiotic) on the demographic determinants of species’ habitat suitability and geographic distributional limits, the research will provide a foundation on which to develop adaptive conservation strategies in response to the anticipated impacts of global change; examine the complexities and potentially irreducible uncertainties in forecasting and managing biodiversity; and identify limitations associated with different modelling approaches.
