Description
Summary:In Hawaii, where there are no native reptiles or amphibians, 27 species of reptiles and amphibians have established; however, few have been studied to determine their ecological impacts. For example, little is known about the impacts of the Puerto Rican frog, Eleutherodactylus coqui Thomas, that recently invaded (late 1980s), and has established on all four main Hawaiian Islands. However, there are likely to be consequences because E. coqui can attain high densities (20570 frogs ha−1 on average in Puerto Rico) and consume large quantities of invertebrates (114000 prey items ha−1 per night on average in Puerto Rico).
