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 ...

Identification of unique species in the marine ecosystem based on the weighted trophic field overlap
MethodsX, 2019 Based on the trophic field overlap of species in the food webs, we propose using the weighted trophic field overlap (WTO) to determine the uniqueness of species in a topological network by considering the food web structure and the proportions of prey in

Isotopic Niche of Three Sympatric Mustelids [PDF]
LifeAlthough sympatric carnivores typically exhibit dietary differentiation to reduce interspecific competition, contemporary isotopic comparisons of European mustelids remain scarce. In this study, we present the first modern stable isotope analysis of hair

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.

Dietary patterns of five freshwater fish species in a large Mediterranean lake
Journal of Freshwater Ecology, 2022 The diet of five freshwater fish species of Lake Trichonis, the largest natural lake of Greece, was studied. Specifically, the studied species were Atherina boyeri, Luciobarbus albanicus, Leucos panosi, Scardinius acarnanicus and Tropidophoxinellus ...

Trophic niche overlap between coyotes and gray foxes in a temperate forest in Durango, Mexico.
PLoS ONE, 2021 Resource partitioning, and especially dietary partitioning, is a mechanism that has been studied for several canid species as a means to understand competitive relationships and the ability of these species to coexist.

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.

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.
