Cage fish farming in hydroelectric reservoirs has been reported to promote variations in environmental conditions, which directly interfere with the foraging behavior of wild fish. We have hypothesized that the abundance ...

Trophic relationships of large pelagic predators can determine the structure and dynamics of oceanic food webs. The feeding habits and trophic ecology of five large pelagic fish (Acanthocybium solandri, Coryphaena hippurus, ...

The objectives of this study were to investigate the food resources consumed by two species of detritivorous fishes along the Apodi-Mossoró River reservoir cascade system, located in the tropical semi-arid region of Brazil. ...

Individual diet specialisation (IS) is frequent in many animal taxa and affects population and community dynamics. The niche variation hypothesis (NVH) predicts that broader population niches should exhibit greater IS than ...

Tropical rainforests support the greatest diversity of small mammals in the world, yet we have little understanding about the mechanisms that promote the coexistence of species. Diet partitioning can favor coexistence by ...

Coexistence of species is associated with differentiation of niches and partitioning of resources, which lessen niche overlap and the intensity of competition. Here, we used stable isotope analysis to evaluate and compare ...

To compare the trophic niche of coexisting larvae of Atopsyche yunguensis and Atopsyche spinosa we analysed their gut contents and found little niche overlap: A. yunguensis fed primarily on Trichoptera and amorphous matter, ...

In seasonal tropical regions, rainfall and/or temporary floods during the wet season generally increase the abundance and diversity of food resources to many consumers as compared to the dry season. Therefore, seasonality ...
