Our research is broadly classified into three categories: animal communication, behavioral drive, and axes of divergence.
Research descriptionThe main focus of the Leal Lab is on behavioral and evolutionary ecology, with a particular interest in lizards. We are primarily interested in elucidating the mechanisms shaping the evolution of behavioral traits and the possible role of behavior in promoting species diversity. To achieve these goals, we take a diversity of approaches integrating behavioral, ecological, neurophysiological, and physiological studies within an evolutionary framework. Whenever possible, our research combines laboratory and field studies. Currently, our research focuses on the evolutionary radiation of West Indian anoles.
