With the official start of the new ARC Centre of Excellence for Australian Biodiversity and Heritage (CABAH) in July, I am pleased to announce two new CABAH-funded postdoctoral positions (a.k.a. Research Associates) in my global ecology lab at Flinders University in Adelaide (Flinders Modelling Node).

One of these positions is a little different, and represents something of an experiment. The Research Associate in Palaeo-Vegetation Modelling is being restricted to women candidates; in other words, we’re only accepting applications from women for this one. In a quest to improve the gender balance in my lab and in universities in general, this is a step in the right direction.

The project itself is not overly prescribed, but we would like something along the following lines of inquiry: Read the rest of this entry »





Journal ranks 2016

14 07 2017

Many books

Last year we wrote a bibliometric paper describing a new way to rank journals, which I contend is a fairer representation of relative citation-based rankings by combining existing ones (e.g., ISI, Google Scholar and Scopus) into a composite rank. So, here are the 2016 ranks for (i) 93 ecology, conservation and multidisciplinary journals, and a subset of (ii) 46 ecology journals, (iii) 21 conservation journals, just as I have done in previous years (201520142013, 2012, 20112010, 2009, 2008).

Human population growth, refugees & environmental degradation

7 07 2017

refugeesThe global human population is now over 7.5 billion, and increasing by about 90 million each year. This means that we are predicted to exceed 9 billion people by 2050, with no peak in site this century and a world population of up to 12 billion by 2100. These staggering numbers are the result of being within the exponential phase of population growth since last century, such that some 14% of all human beings that have ever lived on the planet are still alive today. That is taking into account about the past 200,000 years, or 10,000 generations.

Of course just like the Earth’s resources, human beings are not distributed equally around the globe, nor are the population trends consistent among regions or nations. In fact, developing nations are contributing to the bulk of the global annual increase (around 89 million per year), whereas developed nations are contributing a growth of only about 1 million each year. Another demonstration of the disparity in human population distributon is that about half of all human beings live in just seven countries (China, India, USA, Indonesia, Brazil, Pakistan, Nigeria, and Bangladesh), representing just one quarter of the world’s total land area.

How to respond to reviewers

30 06 2017

Just like there are many styles to writing scientific manuscripts, there are also many ways to respond to a set of criticisms and suggestions from reviewers. Likewise, many people and organisations have compiled lists of what to do, and what not to do, in a response to reviews of your manuscript (just type ‘response to reviewer comments’ or similar phrase into your favourite search engine and behold the reams of available advice).

what

It clearly is a personal choice, but from my own experience as an author, reviewer, editor, and the myriad suggestions available online, there are a few golden rules about how to respond:

  • After you have calmed down a little, it is essential that you remain polite throughout the process. Irrespective of how stupid, unfair, mean-spirited, or just plain lazy the reviewers might appear to you, do not stoop to their level and fire back with defensive, snarky comments. Neither must you ever blame the editor for even the worst types of reviews, because you will do yourself no favours at all by offending the main person who will decide your manuscript’s fate.

Keeping lions from livestock — building fences can save lives

23 06 2017

Seeing majestic lions strolling along the Maasai Mara at sunset — a dream vision for many conservationists, but a nightmare for pastoralists trying to keep their cattle safe at night. Fortunately a conservation success story from Kenya, published today in the journal Conservation Evidence, shows that predation of cattle can be reduced by almost 75% by constructing chain-link livestock fences.

The Anne K. Taylor Fund (AKTF) subsidises over 70% of the cost of building a fully fortified chain-link livestock enclosure (‘boma’) to keep cattle safe from predators at night, in the hope that this will lessen the retaliatory killings of lions by frustrated farmers. While lions, leopards and cheetahs draw in crowds of tourists who marvel at their strength and beauty, living alongside big predators can be tough. Traditionally, local people keep their animals overnight in bomas made of acacia thorns — but depredation by lions and other large carnivores cause losses of on average more than nine head of cattle per year, or US$1870 that farmers see disappear down the throat of big, hairy animals. Building a solid fortification of chain-link fence costs just $890, of which the AKTF paid $638, helping to make this an affordable option for hard-pressed locals. Read the rest of this entry »





Protecting one of the world’s marine wonders

While I’m in transit (yet a-bloody-gain) to Helsinki, I wanted to take this opportunity to reflect on one of the most inspiring eco-tourism experiences I recently had in South Australia.

If you are South Australian and have even the slightest interest in wildlife, you will have of course at least heard of the awe-inspiring mass breeding aggregation of giant cuttlefish (Sepia apama) that occur in May-July every year in upper Spencer Gulf near the small town of Whyalla. If you have been lucky enough to go there and see these amazing creatures themselves, then you know exactly what I’m talking about. And if you haven’t yet been there, take it from me that it is so very much worth it to attempt the voyage.

Despite having lived in South Australia for nearly a decade now, I only got my chance to see these wonderful creatures when a father at my daughter’s school organised a school trip. After driving for five hours from Adelaide to Whyalla, we hired our snorkelling gear and got into the water the very next morning. Read the rest of this entry »





Dangers of the global road-building tsunami

8 06 2017

New roads can be treacherous — even fatal — for wildlife, native forests, and the global environment.

If you don’t believe this, just watch this two-minute video, “Why Roads Are So Dangerous

New roads can also be surprisingly risky for human economies and societies, as shown in this brief video, “Why Roads are Like Pandora’s Box”.
