Studying the sexual dynamics of functional colors in butterflies
Presented by: Vince Ficarrotta, Auburn University, Auburn, Alabama, USA
Abstract: Sexual dimorphism and subsequently sexually selective forces have been existent for much of the duration of the tree of life, contributing to the diversity found within and between species. Advances in sequencing and genetic approaches have led to many breakthroughs that revealed details of the genotype-to-phenotype processes. These details include which genes are necessary for the development of male sexual traits used during courtship and also gives insight into potential genomic processes shaping macroevolutionary patterns contingent on sexual traits. Here, I expand on my work within pierid butterflies where the courtship ritual includes the flashing of iridescent ultraviolet wing patterns, and I conclude with a tour through functional coloration (eg, warning coloration, camouflage, sexual color displays) in communications systems where both sexes must coevolve along their respective roles of sending and/or receiving signals.
