How island foxes are living on the edge
Back in 2016, Robinson et al. (2016) published a genomic analyses of the Channel Island foxes and they showed that despite extremely low genome-wide diversity, the island foxes do not seem to be suffering from inbreeding depression. Read the post … Continue reading

Population genetic simulation … in Lego
Julien Yann Dutheil, of the Institut des Sciences de l’Évolution de Montpellier, has a long track record of work in population genetics and genomics methods, particularly in the C++ programming language. He recently posted a video to YouTube, though, which … Continue reading
La vie en rouge … l'algue rouge
Best laid plans of a #NewPI … what happens to them? Well, they often get triaged for more urgent things that were triaged earlier for more urgent things that were also triaged even earlier for more urgent things … and … Continue reading
Is the neutral theory dead?
You might have noticed how the world of genetics was shaking as the giants of theoretical population genetics started discussing some of the most fundamental questions in the arena of Twittersphere. This happened after the publication of Andrew Kern and Matthew … Continue reading

The secret life of invaders
So I have this pet theory. And damn if the evidence doesn’t seem to be piling up. Am I living in the bubble of my own google alerts? Possibly. I’m an evolutionary ecologist and invasion biologist, and (surprise!) my pet … Continue reading

Are population genomic scans for locally adapted loci too successful?
Last Friday, Molecular Ecology released an interesting new systematic review online ahead of print. Colin Ahrens and coauthors at a number of Australian research institutions compiled results from 66 papers reporting tests for locally adapted loci based on either FST … Continue reading
