Would elephants really replace the woolly mammoth?

Rewilding involves restoring nature at large scales, typically by reintroducing species that have gone extinct and have had important interactions with other organisms.  It has received a lot of popular attention lately, helped in part by George Mobiot’s 2013 book Feral and its growing number of success stories.  But the idea of rewilding remains highly controversial, particularly when it involves adding apex predators like wolves into places with people.  One the reasons for the controversy is the lack of empirical data to assess the effectiveness of its outcomes.  Conservationists are often relying on a handful of well-known examples, such as from Yellowstone National Park.

rewildcoverIn a new paper published last week in the Philosophical Transactions of the Royal Society B, we now summarise the numerical data around whether rewilding works and identify the biases in experimental study.

The paper is part of a special issue on rewilding, organised by Elisabeth Bakker and Jens-Christian Svenning, to which we were kindly asked to contribute towards.  And we were even interviewed in last week’s issue of Science about the special issue and importance of trophic rewilding for the important task of keeping the Arctic cool.

Drooling over plants (literally!)

It is really nice to be able to write about our latest paper, which just came out in Biology Letters to a fair bit of fanfare.  It got picked up by Science, New Scientist – including in their 23 July print issue – and even the Royal Society had a piece about it.  BBC Radio recently had me out to talk to them:

Why so much attention?  Well the paper is one of those quirky but interesting scientific discoveries.  And it is based on drool.  Yup, you read that right, the saliva of large mammals.
