Community genetics

Rocky-shore marine ecology has provided many rich insights into the interactions between organisms and their environments. Despite a fairly deep mechanistic understanding of the benthic and pelagic processes shaping patterns of contemporary community structure on rocky shores, comparatively little is known about the long-term persistence, stability, and historical assembly of these communities.

As a factor affecting community composition and structure over geological timescales, climate change has received the most attention from biologists and paleontologists for two reasons.  Our lab has been conducting phylogeographic surveys in the northeastern Pacific to test several hypotheses about how late Pleistocene climate change has altered rocky-shore community composition.
