Welcome to Marlene Zuk's Lab! Our lab focuses on emerging questions in behavioral ecology and evolutionary biology. We use invertebrate systems to study the evolution of mating behavior and secondary sexual characters in natural populations. Recent studies from the lab have focused on how conflicting natural and sexual selection pressures shape behavior and morphology on individual, population and species levels. We are also interested in how insects defend themselves against the many parasites they are exposed to. Please visit our research page and other links to find out more about the exciting discoveries being made in the lab, and the dedicated people making them!
