Abstract

Butterfly wing patterns are a striking example of biological diversity. The neotropical Heliconius butterflies in particular have extensive within and between species diversity in their wing colour patterns. Some of this diversity is due to variation at the gene cortex, which has repeatedly been targeted by natural selection, both to produce mimetic colour pattern resemblances within Heliconius and remarkably to shift camouflage in the peppered moth. I will also talk about ongoing work in my lab to identify genes controlling iridescent structural colour.

Nicola Nadeau is a NERC Independent Research Fellow in the Department of Animal and Plant Sciences in the University of Sheffield. Her lab group tries to understand evolutionary processes such as adaptation, divergence and speciation. In particular, they want to understand what the genetic changes are that bring about evolutionary change and the interplay between genetics, ecology and evolution. They focus on the evolution of structural colour, convergent evolution and its genetic underpinnings, and genomic approaches to divergence, speciation and adaptation.
