Animals do not exist in a vacuum, and social interactions can have important consequences for survival and reproduction. Dr. Roth’s research integrates across multiple biological levels to explore the evolutionary implications and selective consequences of animal sociality. She uses a variety of study systems (e.g., California quail, three-spined stickleback, treehoppers) and draws on sociality research to examine questions related to disease ecology, sexual selection, and animal personality (i.e., consistent between individual variation in behavior).
