Timothée Bonnet | Postdoc

During my PhD I studied the causes and consequences of variation in Darwinian fitness in a natural population of snow voles (Chionomys nivalis). I found that in the last decade, environmental change had triggered genetic adaptation of body mass and that the process of adaptation was paralleled by a fluctuation in population size. During my postdoc in PopEcol I aim at estimating the respective roles of demographic, genetic, and evolutionary rescues in shaping the demographics of this population.
