A central goal of integrative biology is to understand how genetic and environmental influences interact to produce well adapted phenotypes, but our understanding of how underlying mechanisms bias evolutionary outcomes remains limited. Understanding patterns of mechanistic flexibility and constraint is particularly challenging for behavior, as the brain is a complex, hierarchically organized organ where constant integration of internal and external cues across levels is required to produce context-appropriate behavior. Not to mention this integration must occur across timescales, from minutes to months, to years. The goal of our research is to explore underlying mechanisms to understand how behaviors are generated, maintained, and modified by evolution. We use integrative approaches to address these questions across hierarchical levels of biological organization and timescales. Because fundamental principles governing brains and behavior are most apparent in evolutionary and developmental contexts, we combine lab and field studies to understand variation and adaptation in ecologically relevant behaviors. Currently, we work primarily with charismatic neotropical poison frogs.
