Sexual selection is recognized as a major driving force underlying biodiversity. Comparative studies of closely related species often demonstrate that the traits involved in sexual reproduction are often more divergent than non-sexual traits. From the highly divergent proteins involved in sperm-egg recognition to the complexity in ornaments and courtship displays, sexual traits, on the whole, represent some of the fastest evolving traits in nature.
In our lab, we study reproductive trait evolution: both the microevolutionary processes that drive divergence and the resulting macroevolutionary patterns of biodiversity. How do reproductive traits respond to selection? What is their adaptive significance? What is the underlying genetic variation and fitness consequences associated with variation in trait expression? In order to test our hypotheses and address these questions, we take an integrative approach and utilize a variety of experimental techniques and tools (Field and laboratory studies, quantitative genetics, population genetics and phylogenetics using NGS etc.). Specifically, we are interested in how pre- and postcopulatory sexual selection can result in variation among populations and facilitate the generation and maintenance of barriers to reproduction.
