Explaining the abundance and distribution of marine species often requires identifying the physical and biological factors influencing rates of larval exchange, or connectivity, among populations. Patterns of ocean circulation are clearly important, but most attempts to relate patterns of population differentiation to ocean currents usually only consider mean ocean trajectories over very large spatial scales, potentially yielding unrealistically high expectations for long-distance larval transport.

Our lab has been involved with research focused on patterns of dispersal and connectivity in several harvested species, such lingcod, hammerhead sharks, bay scallops, and barnacles.  Students in my lab have worked in collaboration with Dr. Amy Moran on the thermal performance and tolerances of marine larvae in relation to their geographic distribution and patterns of genetic connectivity.
