Kruuk Group - Evolutionary ecology and quantitative genetics

We study how evolution and ecology shape the biological diversity of natural populations. We aim to understand the effects of both genetic and environmental effects on animal life histories. This includes how climate change is affecting wild animal populations today, as well as studies of the genetic basis of quantitative traits, natural and sexual selection, inbreeding depression, senescence, phenotypic plasticity and maternal effects. Most of my work has been on wild vertebrate species, in particular in studies where we have long-term records over several decades of a population, but I've also worked with collaborators on a range of lab, domestic and plant populations.
