Generalist populations formed by generalist individuals: A case of study on the feeding habits of a neotropical stream fishPopulações generalistas formadas por indivíduos generalistas: Um caso de estudo sobre os hábitos alimentares de um peixe de riacho neotropical
(2021-01-01)
Aim: We described the diet of the generalist stream fish Knodus chapadae and we tested if the environmental conditions are associated with population’s diet and individual specialization. Methods: We analyzed the stomach ...
Trophic ecology of syntopic anuran larvae, Rhinella arenarum (Anura: Bufonidae) and Hypsiboas cordobae (Anura: Hylidae): Its relation to the structure of periphyton
(EDP Sciences, 2015-09)
The grazing of amphibian tadpoles has a significant effect on structure and function of freshwater algal communities. The aim of this study was to evaluate the composition of the diet, the amplitude and degree of overlap ...
Between-individual variation drives the seasonal dynamics in the trophic niche of a Neotropical marsupial

Alimentary niche partitioning in the Galapagos sea lion, Zalophus wollebaeki
(Marine Biology, 2010)
Sea lions are generally considered opportunistic feeders. However, studies from different areas suggest their diet consists mostly of four to five types of prey. Previous studies in Galapagos sea lions have identified at ...
Trophic ecology of the fish Leporinus piau (Characiformes: Anostomidae) in an area influenced by a dam in the Parnaíba River
(Universidad de Costa Rica, 2020)
Do local environmental factors structure the trophic niche of the splash tetra, Copella arnoldi? a test in an Amazonian stream systemFatores ambientais influenciam o nicho trófico do tetra Copella arnoldi? um teste em um sistema lótico amazônico

Trophic niche overlap between two Chilean endemic species of Trichomycterus (Teleostei: Siluriformes)
(Sociedad de Biología de Chile, 2007)
Stable isotopes indicate differing foraging strategies in two sympatric otariids of the Galapagos Islands
(Journal of Experimental Marine Biology and Ecology, 2012)
The feeding behavior of marine predators varies with the level of competition to which they are exposed. Populations living in the same or overlapping geographic regions (sympatric) are generally subject to inter-specific ...
Pisciculturas em tanques-rede interferem nos aspectos alimentares de Metynnis lippincottianus (Characiformes, Serrasalmidae) no reservatório Neotropical?
(Universidade Estadual Paulista (Unesp), 2022-11-18)
Diferenças na dieta e guilda trófica de Metynnis lippincottianus sob influência de pisciculturas em tanques-rede foram avaliadas em um reservatório Neotropical. Foram coletados exemplares dessa espécie em áreas próximas à ...
Individual niche trajectories drive fitness variation
(2019-09-01)
Variation in fitness across individuals is central to population growth, species coexistence and evolution by natural selection. Fitness variation associated with resource use is hugely consequential, but how this variation ...
