The Roberts Lab is a behavioral ecology lab with research interests in the evolution of animal communication and social behavior. Currently, we are particularly interested in context-dependent behavior, that is, behavior(s) that is performed differently depending on the current social, physiological, or environmental context. We apply an integrative approach to our research program, incorporating techniques from several disciplines (e.g. environmental measurements, field and laboratory observation and experimentation, neurohormone and chemical extraction). Such an approach, involving both field and laboratory experimentation is absolutely necessary to address questions about the evolution of animal signals, sexual selection and mate choice, and group formation and social behavior in a rigorous and controlled fashion.
