genetic structuring in the threatened "lagartijo del bosque seco" (anolis cooki) from puerto rico.	species with restricted geographic distributions consisting of isolated populations are particularly susceptible to extinction because these demes face an increased risk of disappearing due to environmental, demographic, and genetic stochasticity. we used partial dna sequences of the cytochrome b (1083 bp) and nd2 (1041 bp) mitochondrial genes to investigate the phylogeography and population genetics of anolis cooki, a threatened lizard endemic to the southwestern coast of the caribbean island o ...	2008	18180174
evidence for habitat partitioning based on adaptation to environmental light in a pair of sympatric lizard species.	terrestrial habitats exhibit a variety of light environments. if species exhibit evolutionary adaptations of their visual system or signals to habitat light conditions, then these conditions can directly influence the structure of communities. we evaluated habitat light characteristics and visual-signal design in a pair of sympatric species of lizards: anolis cooki and anolis cristatellus. we found that each species occupies a distinct microhabitat with respect to light intensity and spectral qu ...	2002	11886622
