The determination of a species trophic niche can clarify its functional role within a food web
and how prey resources are used in relation with the spatial and temporal variability of …

The poison frog family (Anura: Dendrobatidae) consists of species with conspicuous (eg,
warning coloration and toxicity or low palatability) and cryptic (eg, palatable, and …

The species Boana bischoffi and Boana marginata are endemic to the Atlantic Forest, where
they often occur in sympatry. There is a large gap in the knowledge of natural history of both …

Our objective was to describe and compare the diet of endemic anurans of the Atlantic
Forest, as well as to evaluate the influence of biotic factors on the trophic ecology of the …

Sphyrna lewini is a placental viviparous shark that uses coastal nursery areas in Jalisco,
Mexico, where pups stay 4–12 months. Changes in size or swimming speed may be …

Anurans fit an important trophic position in ecosystems because they are both predators and
prey of many invertebrate and vertebrate organisms. Here, we describe the diet and …

Frog diets are influenced by multiple factors, including morphological constraints, habitat
use, and seasonal variation in environmental conditions and food availability. This study …

We studied the diet of Rhinella major from temporary lentic water bodies from an urban area
in Amapá state, North Brazil. A total of 59 frogs were manually collected between January …

Information on the use of food resources and habitat are important tools for understanding
trophic niche and ecological relationships. Many factors can influence the diet and eating …

Given the increasing use of sympatric species to investigate niche differentiation and
resource partition in biological communities, our study analyzes diet composition differences …
