Coevolution and the Organization of Biodiversity

Research in my laboratory is on the ways in which coevolution between species organizes the earth's biodiversity. My long-term goal is to understand how coevolving interactions are genetically and ecologically organized across broad geographic landscapes and how they connect biological communities. Our work includes studies of species interactions across many types of environments, from relatively pristine landscapes to others that are becoming increasingly fragmented and modified by introduced taxa. Most of our empirical work uses interactions between insects and plants (herbivores and plants; pollinators and flowers), because these are among the most diverse groups of organisms on earth. We use a wide range of ecological, genetic, molecular, and evolutionary approaches to study the dynamics of coevolution.

Current Research

We are currently evaluating the geographic structure and evolutionary dynamics of a variety of species interactions distributed throughout western North America; We are asking how

interacting species differ in geographic structure and local adaptation, how local coevolutionary hotspots shape the overall genetic structure and evolutionary trajectories of interactions, and how the evolution of polyploidy in plant populations leads to the diversification of plant species and interactions with other taxa.
