Influential conservation papers of 2014

22 12 2014

splash2Another year, another arbitrary retrospective list – but I’m still going to do it. Based on the popularity of last year’s retrospective list of influential conservation papers as assessed through F1000 Prime, here are 20 conservation papers published in 2014 that impressed the Faculty members.

Once again for copyright reasons, I can’t give the whole text but I’ve given the links to the F1000 assessments (if you’re a subscriber) and of course, to the papers themselves. I did not order these based on any particular criterion.

Another 589 scientists speak out against Abbott’s war on the environment

22 07 2014

ATBC_logo_largeI’m currently in Cairns at the Association for Tropical Biology and Conservation‘s Annual Conference where scientists from all over the world have amassed for get the latest on tropical ecology and conservation. Unfortunately, all of them have arrived in an Australia different to the one they knew or admired from afar. The environmental devastation unleashed by the stupid policies of the Abbottoir government has attracted the attention and ire of some of the world’s top scientists. This is what they have to say about it (with a little help from me):

ASSOCIATION FOR TROPICAL BIOLOGY AND CONSERVATION

RESOLUTION IN SUPPORT OF STRONGER LAWS FOR CLIMATE-CHANGE MITIGATION AND ENVIRONMENTAL PROTECTION IN AUSTRALIA

Australia has many trees, amphibians, and reptiles that are unique, being found nowhere else on Earth. Northern Australia contains a disproportionate amount of this biodiversity which occurs in little developed areas, parks and reserves, indigenous titled lands, and community-managed lands.

Whilst Australia’s achievements in protecting some of its remaining native forests, wildlife and wilderness are applauded, some 6 million hectares of forest have been lost since 2000. Existing forest protection will be undermined by weak climate change legislation, and poorly regulated agricultural and urban development.

The Association for Tropical Biology and Conservation (ATBC), the world’s largest organisation dedicated to the study and conservation of tropical ecosystems, is concerned about recent changes in Australia’s environmental regulations, reduced funding for scientific and environmental research, and support for governmental and civil society organisations concerned with the environment.

New Threatened Species Commissioner lacks teeth

2 07 2014

This is not Gregory Andrews

Published today on ABC Environment.

Greg Hunt, the Coalition Government’s Minister for the Environment, today announced what appears to be one of the only environmental promises kept from their election campaign in 2013: to appoint a Threatened Species Commissioner.

The appointment is unprecedented for Australia – we have never had anything remotely like it in the past. However, I am also confident that this novelty will turn out to be one of the position’s only positives.

My scepticism is not based on my personal political or philosophical perspectives; rather, it arises from Coalition Government’s other unprecedented policies to destroy Australia’s environment. No other government in the last 50 years has mounted such a breath-taking War on the Environment. In the nine month’s since the Abbott Government took control, there has been a litany of backward and dangerous policies, from the well-known axing of the Climate Commission and their push to dump of 3 million tonnes of dredge on the World Heritage Great Barrier Reef, to their lesser-publicised proposals to remove the non-profit tax status of green organisations and kill the Environmental Defenders Office. The Government’s list of destructive, right-wing, anti-environmental policies is growing weekly, with no signs of abatement.

With this background, it should come as no surprise that considerable cynicism is emerging following the Minister’s announcement. Fears that another powerless pawn of the current government appear to have been realised with the appointment of Gregory Andrews as the Commissioner. Mr Andrews is a public servant (ironically from the now-defunct Department of Department of Climate Change and Energy Efficiency) and former diplomat who has some minor infamy regarding contentious comments he made in 2006 when acting as a senior bureaucrat in Mal Brough’s Department of Indigenous Affairs. Apart from Mr Gregory’s general lack of specific expertise in species recovery, the choice appears to be neutral at best.

More importantly, the major limitation of the Commissioner to realise real benefits for Australian biodiversity is the position’s total lack of political power. Greg Hunt himself confirmed that Mr Andrews will not be able to affect government policy other than ‘encourage’ cooperation between states and environmental groups. The position also comes with a (undisclosed) funding guarantee of only one year, which makes it sound more like an experiment in public relations than effective environmental policy.

We’re sorry, but 50/500 is still too few

28 01 2014

too fewSome of you who are familiar with my colleagues’ and my work will know that we have been investigating the minimum viable population size concept for years (see references at the end of this post). Little did I know when I started this line of scientific inquiry that it would end up creating more than a few adversaries.

It might be a philosophical perspective that people adopt when refusing to believe that there is any such thing as a ‘minimum’ number of individuals in a population required to guarantee a high (i.e., almost assured) probability of persistence. I’m not sure. For whatever reason though, there have been some fierce opponents to the concept, or any application of it.

Yet a sizeable chunk of quantitative conservation ecology develops – in various forms – population viability analyses to estimate the probability that a population (or entire species) will go extinct. When the probability is unacceptably high, then various management approaches can be employed (and modelled) to improve the population’s fate. The flip side of such an analysis is, of course, seeing at what population size the probability of extinction becomes negligible.

‘Negligible’ is a subjective term in itself, just like the word ‘very‘ can mean different things to different people. This is why we looked into standardising the criteria for ‘negligible’ for minimum viable population sizes, almost exactly what the near universally accepted IUCN Red List attempts to do with its various (categorical) extinction risk categories.

But most reasonable people are likely to agree that < 1 % chance of going extinct over many generations (40, in the case of our suggestion) is an acceptable target. I’d feel pretty safe personally if my own family’s probability of surviving was > 99 % over the next 40 generations.

Some people, however, baulk at the notion of making generalisations in ecology (funny – I was always under the impression that was exactly what we were supposed to be doing as scientists – finding how things worked in most situations, such that the mechanisms become clearer and clearer – call me a dreamer).

So when we were attacked in several high-profile journals, it came as something of a surprise. The latest lashing came in the form of a Trends in Ecology and Evolution article. We wrote a (necessarily short) response to that article, identifying its inaccuracies and contradictions, but we were unable to expand completely on the inadequacies of that article. However, I’m happy to say that now we have, and we have expanded our commentary on that paper into a broader review. Read the rest of this entry »





Influential conservation papers of 2013

31 12 2013

big-splash1This is a little bit of a bandwagon – the ‘retrospective’ post at the end of the year – but this one is not merely a rehash I’ve stuff I’ve already covered.

I decided that it would be worthwhile to cover some of the ‘big’ conservation papers of 2013 as ranked by F1000 Prime. For copyright reasons, I can’t divulge the entire synopsis of each paper, but I can give you a brief run-down of the papers that caught the eye of fellow F1000 faculty members and me. If you don’t subscribe to F1000, then you’ll have to settle with my briefest of abstracts.

In no particular order then, here are some of the conservation papers that made a splash (positively, negatively or controversially) in 2013:
