Diets of Three Sympatric Grebe Species in Lake Titicaca Indicate Possible Dietary Niche Partitioning

Ecology and Evolution
Dietary niche partitioning is a fundamental process in community ecology, of interest to both conservationists and ecologists. We present data on the dietary niches of three sympatric grebes from Lake Titicaca: the endangered endemic Titicaca Grebe ...

Sexual dimorphism does not translate into foraging or trophic niche partitioning in Peruvian boobies (Sula variegata).

PLoS ONE
Intraspecific competition can lead to sexual segregation of diets or foraging behaviors in seabirds, and in some species the resulting niche partitioning is facilitated by sexual dimorphism.

Temporal and spatial niche partitioning of four sympatric ungulate species in Wuyishan National Park, China

Global Ecology and Conservation
Niche partitioning is a key factor in mitigating competition among sympatric species that share limited resources, thereby contributing to their coexistence.

Within-population isotopic niche variability in savanna mammals: disparity between carnivores and herbivores

Frontiers in Ecology and Evolution, 2016
Large mammal ecosystems have relatively simple food webs, usually comprising three – and sometimes only two – trophic links. Since many syntopic species from the same trophic level therefore share resources, dietary niche partitioning features ...

Trophic ecology of the African riverine elephant fishes (Mormyridae)

Ecology and Evolution
Multiple species of the elephant fishes (Mormyridae) commonly coexist in sympatry in most African tropical rivers and lakes. In this study, we investigated the trophic ecology and potential trophic niche partitioning of eleven mormyrid fish species from ...

The Spatial Niche and Influencing Factors of Desert Rodents

Animals
Resource partitioning may allow species coexistence. Sand dunes in the typical steppe of Alxa Desert Inner Mongolia, China, consisting of desert, shrub, and grass habitats, provide an appropriate system for studies of spatial niche partitioning among ...

Temporal, Spatial and Prey Niche Partitioning Reveals Coexistence Mechanism of Mesocarnivores in Guangdong Province, South China

Ecology and Evolution
Mesocarnivores are expected to maintain ecosystem function and stability as emerging apex predators after the decline and extinction of large carnivores.

Unveiling the mysteries of Asian herbivores resource partitioning in tropical wet-grassland ecosystem

Global Ecology and Conservation
Ecological niche partitioning is fundamental for the coexistence of sympatric species. However, the relationship between herbivore body size and forage availability on resource segregation and selection remains debatable.
