This research investigates the interaction between
selection, gene flow, adaptation, reproductive isolation, and population
dynamics. The above photo shows stickleback from Misty Lake (top in the above
and left in the below) and from the stream that flows into Misty Lake (bottom
in the above and right in the below). In short, we have found that natural
selection promotes the adaptive divergence of lake and stream stickleback, but
that the magnitude of divergence – and even population persistence – can be
constrained by gene flow. We are also examining whether adaptive divergence
feeds back on gene flow by causing the evolution of reproductive isolation
(i.e., ecological speciation).
