Thriving in a hostile world: Insights from the dietary strategy of two allopatric, closely related tepui summit endemic amphibians.

To date, there has been no published investigation on the trophic diversity in any tepui summit vertebrate. In this paper, we analyzed the dietary composition of a tepui summit endemic toad, from Roraima-tepui, and compared it with that of from Kukenán-tepui, to examine to what extent diet differs between these two sister species across isolated, although neighboring, tepui tops. The digestive tracts of a total of 197 toads were dissected: 111 from and 86 from .
