Individual-level diet variation in four species of Brazilian frogs.
Explore this paper's citation graph
Summary
The degree of interindividual diet variation in four species of frogs of the highly diverse Brazilian Cerrado is measured, using both gut contents and delta(13)C stable isotopes, indicating that this phenomenon is not restricted to depauperate communities in temperate regions.
