The Pruitt Lab is interested in the interactions between individual traits and the collective attributes of animal societies and biological communities. We explore how the behaviors of individual group members contribute to collective phenotypes, and how these collective phenotypes in turn influence the persistence and stability of collective units (social groups, communities, etc.). Our most recent research explores the factors that lead to the collapse of biological systems, and which factors may promote a system's ability to bounce back from undesirable alternative persistent states.
