Genetic structure among 50 species of the northeastern Pacific rocky intertidal community.

Comparing many species' population genetic patterns across the same seascape can identify species with different levels of structure, and suggest hypotheses about the processes that cause such variation for species in the same ecosystem. This comparative approach helps focus on geographic barri...
