Phylogenetic analysis of the evolution of the niche in lizards of the Anolis sagrei group.

Candidates for dispersal may reduce these risks by making decisions based on the level of connectivity between patches, e.g., through immigrants. The benefits of information acquisition may vary within a population according t...
