A species that has a high rate of long-distance dispersal is more likely to colonize new habitat. But that species may also be less likely to adapt to local conditions, because migration will be stronger than local selection pressures for many loci. In light of those considerations, when do you expect that increasing dispersal might result in the evolution of a larger geographic range, and when might it not?
