Human disturbance increases trophic niche overlap in terrestrial carnivore communities [PDF]
Proceedings of the National Academy of Sciences, 2020 Significance Niche theory posits that species must limit overlap in the use of space, time, or resources to minimize competition. However, human disturbances are rapidly altering ecosystems with uncertain consequences for niche partitioning. Dietary niche partitioning is the primary way many species limit interspecific competition, and it is ...

Trophic Niches, Trophic Positions, and Niche Overlaps between Non-Native and Native Fish Species in a Subalpine Lake [PDF]
Water, 2020 In the last century, Italian freshwater ecosystems have been invaded by several non-native fish species. In the subalpine Lake Mergozzo (northern Italy), several recently introduced non-native species dramatically expanded their populations. We used carbon and nitrogen stable isotopes to describe the isotopic niches and trophic positions of native and ...

High trophic niche overlap in mixed‐species colonies using artificial nests [PDF]
Ibis, 2022 Although successful at recovering endangered populations, conservation actions based on nest provisioning seldom consider how they shape the composition of communities and alter interspecific interactions. Specifically, the extent to which dietary overlap within these communities may affect the conservation of target species has rarely been assessed ...

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 ...

Feeding habits and trophic niche overlap in a Carnivora community of Hungary [PDF]
Acta Theriologica, 1999 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.

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.

Trophic niche size and overlap decreases with increasing ecosystem productivity
Oikos, 2020 The production and transfer of biomass through trophic relationships is a core ecosystem function. The movement of energy through the food web is mediated by organisms operating in their niche space. For generalists, the size of this niche space is inherently plastic and changes in response to available food sources.

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.
