Non-random dispersal can promote evolutionary divergence, even in the absence of spatial variation in selection. However, in most systems we lack the empirical data on movement behavior needed to assess this mechanism of divergence. Capitalizing on movement data for two stream-associated plethodontid salamanders, we tested the hypothesis that non-random dispersal promotes genetic and phenotypic divergence in upland, headwater areas hotspots of plethodontid diversity. Results of this work underscore the value of direct data on movement for predicting population connectivity in complex landscapes, and provide new insight on the contribution of non-random movement behavior to fine-scale evolutionary divergence. I will also present results from a current study that uses long-term mark-recapture data to explore how temporal and spatial variation in habitat quality affect the frequency of long-distance dispersal. Ultimately, I hope this work will improve understanding of the evolution of long-distance dispersal and, more specifically, of why it occurs and how it is maintained in populations.
