Abstract excerpt
In the Pleistocene, climatic changes resulted in cycles of sea-level fluctuation that periodically fragmented islands into aggregate island complexes. These temporary saltwater barriers between islands within an island bank had the potential to decrease migration between populations on separate islands, resulting in increased genetic divergence and potentially speciation. In the Lesser Antilles, Anolis lizards...
