Rate My Professor Jon Evans

Evans' research centers on evolutionary biology, emphasizing post-copulatory sexual selection, sperm competition, ejaculate evolution, and paternal effects in poeciliid fishes such as guppies (Poecilia reticulata) and in terrestrial-breeding frogs. Key publications include "Directional postcopulatory sexual selection revealed by artificial insemination" (Evans et al., Animal Behaviour, 2003), "The ontogeny of courtship, colour and sperm production in male guppies" (Evans et al., Proceedings of the Royal Society B: Biological Sciences, 2002), "The effects of inbreeding on male courtship behaviour and coloration in guppies" (Mariette et al., Journal of Evolutionary Biology, 2006), "Male phenotype and sperm number in the guppy (Poecilia reticulata)" (Pitcher & Evans, Animal Behaviour, 2001), and "Sperm competition: linking form to function" (Humphries et al., Proceedings of the Royal Society B: Biological Sciences, 2008). He co-edited the book "Ecology and Evolution of Poeciliid Fishes" (Pilastro, Evans & Schlupp, University of Chicago Press, 2011). Evans has made significant contributions through datasets on topics such as sperm traits' dependence on male condition, geographic variation in testes size and ejaculate traits, and fertilization success related to genetic relatedness. He has received prestigious ARC fellowships and a recent ARC grant to study causes and consequences of gamete trait variation. As a member of the Centre for Evolutionary Biology, he co-coordinates courses including Behavioural Ecology (ANIM3365) and The Darwinian Revolution (ANIM2001).
