Trophic niche overlap between two Chilean endemic species of Trichomycterus (Teleostei: Siluriformes) [PDF]
Trichomycterus areolatus y Trichomycterus chiltoni son peces Siluriformes endemicos de Chile, siendo las unicas especies chilenas conocidas de este genero que coexisten en simpatria. Se encontro alta sobreposicion de nicho trofico entre estas dos especies.

Trophic ecology and niche overlap of two sympatric species of Rhamdia (Siluriformes, Heptapteridae) from northeast Oaxaca, Mexico [PDF]
The trophic ecology of fishes in the genus Rhamdia remains poorly reported. Here, we aim to describe the diet composition and infer the trophic levels, niche breadth, and niche overlap between Rhamdia guatemalensis and Rhamdia laticauda in northeast ...

Feeding habits and trophic niche overlap in a Carnivora community of Hungary [PDF]
The seasonal feeding habits of the red fox Vulpes vulpes (Linnaeus, 1758), the stone marten Martes foina (Erxleben, 1777), the stoat Mustela erminea Linnaeus, 1758, the badger Meles meles (Linnaeus, 1758) and the otter Lutra lutra(Linnaeus, 1758) were studied in south-west Hungary, in the course of four years.

Invasive signal crayfish and native noble crayfish show trophic niche shrinkage in sympatry [PDF]
Studying the coexistence of native species and invasive species with similar functional traits, habitat usage, and feeding habits is crucial for understanding the dynamics of invasion and ecological changes in the invaded ecosystem.

Trophic niche overlap among scavengers in Patagonia supports the condor-vulture competition hypothesis [PDF]
SummaryAnimals that share resources tend to use different foraging strategies in order to decrease potential competition. Scavenging birds using the same nutritional resources can segregate into different space and time scales. However, it has been suggested that when the species do not co-evolve to achieve such segregation competition may result.

Diet and trophic niche of Lithobates catesbeianus (Amphibia: Anura)
Lithobates catesbeianus (Shaw, 1802) is an invasive anuran introduced in Brazil that is associated with the displacement and the decline of populations of native species worldwide.

The trophic interactions between consumers and resources play a vital role in the stability of communities. In river systems, fragmentation of natural habitats and environmental changes alters the energy basis and community composition, consequently ...

Lizard assemblage from a sand dune habitat from southeastern Brazil: a niche overlap analysis
Communities are structured by interactions of historical and ecological factors, which influence the use of different resources in time and space. We acquired data on time of activity, microhabitat use and diet of a lizard assemblage from a sand dune ...
