Trophic niche overlap between sympatric harbour seals (Phoca vitulina) and grey seals (Halichoerus grypus) at the southern limit of their European range (Eastern English Channel) [PDF]
Ecology and Evolution, 2021 Sympatric harbour (Phoca vitulina) and grey seals (Halichoerus grypus) are increasingly considered potential competitors, especially since recent local declines in harbour seal numbers while grey seal numbers remained stable or increased at their ...

Ecosystem, spatial and trophic dimensions of niche partitioning among freshwater fish predators [PDF]
Movement EcologyBackground Niche partitioning allows species to diversify resource utilisation and space allocation and reduce interspecific competition. Variations in abiotic and biotic conditions in different ecosystems may further influence resource availability and ...

Functional Trait Divergence in Feeding Ecology Between Two Closely Related Upeneus Species in the Beibu Gulf: An Ecological Morphology Analysis [PDF]
Ecology and EvolutionClosely related species coexisting in the same habitat often undergo niche differentiation or morphological adaptations to reduce interspecific competition and secure sufficient resources, particularly when their ecological niches overlap.

Isotope niche dimension and trophic overlap between bigheaded carps and native filter-feeding fish in the lower Missouri River, USA. [PDF]
PLoS ONE, 2018 Stable carbon and nitrogen isotope values (δ13C and δ15N) were used to evaluate trophic niche overlap between two filter-feeding fishes (known together as bigheaded carp) native to China, silver carp (Hypophthalmichthys molitrix) and bighead carp ...

Peri‐urban systems alter trophic niche size and overlap in sympatric coastal bird species
Ecosphere, 2023 Urban habitats can create empty trophic niche space by providing abundant alternative dietary resources, allowing some generalist species to either shift or expand their trophic niches.

Interspecies trophic niche differences and spatial–temporal adaptations found in Cultrinae fishes
Frontiers in Ecology and Evolution, 2023 It has been debated whether interspecies niche differences may follow niche conservatism, whether niches are becoming specialists, whether generalists and specialists are maintained in a balance, and how the realized niche may adapt to local or temporal ...

Trophic ecology of sea urchins in coral-rocky reef systems, Ecuador [PDF]
PeerJ, 2016 Sea urchins are important grazers and influence reef development in the Eastern Tropical Pacific (ETP). Diadema mexicanum and Eucidaris thouarsii are the most important sea urchins on the Ecuadorian coastal reefs.

Intraguild niche partitioning in granivorous birds from the late past
Avian Research, 2023 Niche partitioning is a widespread ecological strategy within trophic guilds, ensuring the coexistence of sympatric species by reducing interspecific competition.

Ecology and Evolution, 2021 The partition of the ecological niche can enhance the coexistence of predators due to differences in how they exploit three main resources: food, space, and time, the latter being an axis that often remains unexplored.
