My PhD research is focused on uncovering the patterns of sexual selection that lead to stunning diversity in the size and shape of animal weapons. I am currently studying the interplay of ecological context, mating systems, and sexual competition in populations of the unicorn beetle, Trypoxylus dichotomus. These beetles have evolved shorter horns in Taiwan than in Japan. Closely related subspecies across southern Asia show similar horn variation. I am exploring whether the specific balance of selective pressures that produce exaggerated weapons is patchy enough in space and time to explain the great diversity seen in sexually selected weapons. I will first study environments in rhino beetle subspecies and will later expand these ideas to other weaponed systems. Ultimately, I wish to contribute a clearer understanding of weapon evolution and how sexual selection operates in different environments.
