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

Trophic overlap between fish and riparian spiders: potential impacts of an invasive fish on terrestrial consumers [PDF]
Ecology and Evolution, 2016 AbstractStudies on resource sharing and partitioning generally consider species that occur in the same habitat. However, subsidies between linked habitats, such as streams and riparian zones, create potential for competition between populations which never directly interact. Evidence suggests that the abundance of riparian consumers declines after fish

Trophic overlap between expanding and contracting fish predators in a range margin undergoing change. [PDF]
Sci Rep, 2018 AbstractClimate change is predicted to cause a freshening of the Baltic Sea, facilitating range expansions of freshwater species and contractions of marine. Resident marine flounders (Platichthys flesus) and expansive freshwater roach (Rutilus rutilus) are dominant consumers in the Baltic Sea sublittoral where they occur in partial sympatry.

High Trophic Niche Overlap between a Native and Invasive Mink Does Not Drive Trophic Displacement of the Native Mink during an Invasion Process [PDF]
Animals, 2020 The pressure elicited by invasive species on native species significantly increases with the increase of the overlap of their ecological niches. Still, the specific mechanisms of the trophic displacement of native species during the invasion process are unclear.

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.

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

Uniqueness measure based on the weighted trophic field overlap of species in the food web
Ecological Indicators, 2019 With the application of the topological network concept to study food webs, species uniqueness in terms of irreplaceability has begun to be considered when identifying important species in the ecosystem. Based on the uniqueness method of quantifying the interactions and trophic field overlap of species in food webs, we propose using the weighted ...

Anthropogenic Disturbance Mediates Trophic Niche Overlap Between Sympatric Generalist Predators
Integrative ZoologyAbstract Human activities generally increase trophic overlap in predator guilds through resource subsidies, whereas the effects on whether sympatric species overlap or separate their niches are context‐dependent.
