Data from: Thriving in a hostile world: insights from the dietary strategy of two allopatric, closely-related tepui summit endemic amphibians
<p>To date, there has been no published investigation on the trophic diversity in any tepui summit vertebrate. In this paper we analysed the dietary composition of a tepui summit endemic toad, <i>Oreophrynella quelchii</i> from Roraima-tepui, and compared it with that of <i>O. nigra</i>, to examine to what extent diet differs between these two sister species across isolated, although neighbouring, tepui tops. The digestive tracts of a total of 197 toads were dissected: 111 from <i>O. quelchii</i> and 86 from <i>O. nigra</i>. The diet composition of <i>O. quelchii</i> was relatively diverse, with 13 major prey categories; mites (Acari, 36.5%) and beetles (Coleoptera, 21.0%) numerically dominated its diet. Despite occurring on two different tepui summits, <i>O. quelchii </i>and <i>O. nigra</i> exhibited a similar diet composition, although in <i>O. nigra</i> mites (Acari, 42.4%) and hymenopterans (especially ants, 16.9%) numerically dominated the diet. The present data suggest that tepui summit <i>Oreophrynella</i> species are flexible in their diet and are active foragers that also feed on aquatic arthropods, successful strategies in tepui competitive environments.</p>
