The lizard fauna of Guam's fringing islets: Island biogeography, phylogenetic history, and conservation implications The lizard fauna of Guam's fringing islets: Island biogeography, phylogenetic history, and conservation implications
We sampled the lizard fauna of twenty-two small islets fringing the Pacific island of Guam and used these data to shed light on the processes responsible for present-day diversity. Habitat diversity, measured by islet area and vegetation complexity, was significantly correlated with the number of species found on an islet. However, islet distance and elevation were not significant...

The role of introduced species in the degradation of island ecosystems: A case history of Guam The role of introduced species in the degradation of island ecosystems: A case history of Guam
The accidental introduction of the brown treesnake (Boiga irregularis) on Guam around 1950 induced a cascade of extirpations that may be unprecedented among historical extinction events in taxonomic scope and severity. Birds, bats, and reptiles were affected, and by 1990 most forested areas on Guam retained only three native vertebrates, all of which were small lizards. Of the hypotheses...

The disappearance of Guam's wildlife: New insights for herpetology, evolutionary ecology, and conservation The disappearance of Guam's wildlife: New insights for herpetology, evolutionary ecology, and conservation
The wealth of data generated from intensive study of the brown tree snake as a result of the need to control introduced populations of this pest species allow several important conclusions. First, that the snakes on Guam are extraordinary in terms of their absolute abundance and in terms of their ability to exploit a broad prey base. Our data suggest an exceptionally high reproductive...
