A posthumous citation tribute for Sodhi

6 11 2012

I’m sitting at a friend’s house in Sydney writing this quick entry before jumping on a plane to London. It’s been a busy few days, and will be an even busier next few weeks.

I met with Paul and Anne Ehrlich yesterday (who are visiting Australia) and we finalised the first complete draft of our book – I will keep you posted on that. In London, I will be meeting with the Journal of Animal Ecology crew on Wednesday night (I’m on the editorial board), followed by two very interesting days at the Zoological Society of London‘s Protected Areas Symposium at Regent’s Park. Then I’ll be off to the Universities of Liverpool and York for a quick lecture tour, followed by a very long trip back home. I’m already tired.

In the meantime, I thought I’d share a little bit of news about our dear and recently deceased friend and colleague, Navjot Sodhi. We’ve already written several times our personal tributes (see here, here and here) to this great mind of conservation thinking who disappeared from us far too soon, but this is a little different. Barry Brook, as is his wont to do, came up with a great idea to get Navjot up posthumously on Google Scholar.

Slicing the second ‘lung of the planet’

12 12 2011


Apologies for the slow-down in postings this past week – as many of you know, I was attending the International Congress for Conservation Biology in Auckland. I’ll blog about the conference later (and the stoush that didn’t really occur), but suffice it to say it was very much worthwhile.

This post doesn’t have a lot to do per se with the conference, but it was stimulated by a talk I attended by Conservation Scholar Stuart Pimm. Now, Stuart is known mainly as a tropical conservation biologist, but as it turns out, he also is a champion of temperate forests – he even sits on the science panel of the International Boreal Conservation Campaign.

I too have dabbled in boreal issues over my career, and most recently with a review published in Trends in Ecology and Evolution on the knife-edge plight of boreal biodiversity and carbon stores. That paper was in fact the result of a brain-storming session Navjot Sodhi and I had one day during my visit to Singapore sometime in 2007. We thought, “It doesn’t really seem that people are focussing their conservation attention on the boreal forest; how bad is it really?”.

Well, it turns out that the boreal forest is still a vast expanse and that there aren’t too many species in imminent danger of extinction; however, that’s where the good news ends. The forest itself is becoming more and more fragmented from industrial development (namely, forestry, mining, petroleum surveying and road-building) and the fire regime has changed irrevocably from a combination of climate change and intensified human presence. You can read all these salient features here.

So, back to my original thread – Stuart gave a great talk on the patterns of deforestation worldwide, with particular emphasis on how satellite imagery hides much of the fine-scale damage that we humans do to the world’s great forests. It was when he said (paraphrased) that “50,000 km2 of boreal forest is lost each year, but even that statistic hides a major checkerboard effect” that my interest was peaked.

Twenty landmark papers in biodiversity conservation

13 10 2011

While I can’t claim that this is the first time one of my peer-reviewed papers has been inspired by ConservationBytes.com, I can claim that this is the first time a peer-reviewed paper is derived from the blog.

After a bit of a sordid history of review (isn’t it more and more like that these days?), I have the pleasure of announcing that our paper ‘Twenty landmark papers in biodiversity conservation‘ has now been published as an open-access chapter in the new book ‘Research in Biodiversity – Models and Applications‘ (InTech).

Perhaps not the most conventional of venues (at least, not for me), but it is at the very least ‘out there’ now and freely available.

The paper itself was taken, modified, elaborated and over-hauled from text written in this very blog – the ‘Classics‘ section of ConservationBytes.com. Now, if you’re an avid follower of CB, then the chapter won’t probably represent anything terribly new; however, I encourage you to read it anyway given that it is a vetted overview of possibly some of the most important papers written in conservation biology.

If you are new to the field, an active student or merely need a ‘refresher’ regarding the big leaps forward in this discipline, then this chapter is for you.

The paper’s outline is as follows: Read the rest of this entry »

Life, death and Linneaus

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 »

Time to cough up for Navjot

27 06 2011

You’d have to have been living under a rock for the last two weeks not to know that our esteemed colleague, great mate and all-round poker-in-the-eyes-of-convention, Professor Navjot Sodhi, died tragically on 12 June 2011 of lymphoma. but just in case you were under a rock, you can read about it here.

In the weeks that have elapsed, several amazing things have happened – despite Navjot being a complete bastard (note: I use this term in the Australian parlance meaning ‘one who could hold his own, who could detect bullshit at 100 m, who was a wonderful mate, and an even more terrible enemy’ – in essence, the highest compliment and expression of platonic love a man can give to another), his army of students, colleagues, admirers and distant relatives have flown into action to make damn sure he is not forgotten.

First, the outpouring of grief and accolades in the blogosphere hit a pick the week following his death (see here, here and here for examples). There was even a Facebook tribute page established within days. It just so happened too that he died during the Association for Tropical Biology and Conservation‘s annual meeting in Arusha, Tanzania (and with whom Navjot was a council member). I have heard from the likes of Bill Laurance, Luke Gibson, Nigel Stork and others that the meeting ended up essentially being in honour of Navjot once everyone heard the dreadful news.

How fast are we losing species anyway?

28 03 2011

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).

They always whinge about the maths

18 11 2010

If you don’t know what a differential equation is, you are not a scientist” – Hugh Possingham 2009

At the end of 2009 I highlighted a new book edited by good mates Navjot Sodhi and Paul Ehrlich, Conservation Biology for All, in which Barry Brook and I had written a chapter. Now, despite my vested interest, I thought (and still think) that it was one of the best books on conservation biology yet published, and the subsequent reviews appear to be validating my subjective opinion.

I’ve given snippets of the book’s contents, from Paul Ehrlich‘s editorial on the human population’s rising negative influences on biodiversity, to a more detailed synopsis of our chapter, The Conservation Biologist’s Toolbox, and I’ve reproduced a review printed in Trends in Ecology and Evolution.

The latest review by Nicole Gross-Camp of the University of East Anglia published in Ecology is no less flattering – in fact, it is the most flattering to date. So this is by no means a whinge about a whinge; rather, consider it an academic lament followed by a query. First, the review:

Reaching higher in conservation

If a book could receive a standing ovation—this one is a candidate. Sodhi and Ehrlich have created a comprehensive introduction to conservation biology that is accessible intellectually, and financially, to a broad audience—indeed it is Conservation biology for all. The book is divided into 16 chapters that can stand alone and are complementary when read in sequence. The authors make excellent use of cross citations of chapters, a useful and often overlooked feature in texts of this nature. In the introductory chapter, Sodhi and Ehrlich eloquently summarize the gravity of the conservation crisis and still retain an optimistic outlook that encourages the reader to continue. I particularly found their recognition of population growth, consumption, and ethics in the conservation arena refreshing and a step toward what will likely become the next major issues of discussion and research in the conservation field.
