Perspectives

ECOLOGY:
Population Evolution and Island Biogeography

Roger S. Thorpe

Large-scale field experiments on population ecology and evolution are problematic. In his Perspective, Thorpe discusses the study by Schoener et al. in the same issue that shows how Caribbean anoles have lent themselves to both difficult field experiments and comparative studies. Such studies have illuminated the population processes such as species competition, predation, adaptation, and speciation that ultimately lead to the broad biogeographic patterns we observe.
