Research in the Trillo lab integrates the fields of behavior, ecology, and evolution, and uses a wide variety of tools, including field-based, bio-acoustic, and genetic tools, to understand trait evolution and diversification. We collect much of our data in the tropics and in affiliation with the Smithsonian Tropical Research Institute. We are currently pursuing three areas of research. The first area examines the effects of eavesdropping predators and parasites on the calling dynamics of mixed frog choruses and on species divergence. The second area explores the influence of host-plant derived chemicals on antipredator defenses in beetles, and the third area focuses on the effects of multiple mating on sexual trait evolution in beetles.
