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.

Parasitism as a Driver of Trophic Niche Specialisation. [PDF]
Trends in Parasitology, 2016 The population trophic niche of free-living species can be subdivided into smaller niches comprising individuals specialising on specific food items. The roles of parasites in creating these specialised subgroups remain unclear.

Mechanisms of trophic niche compression: Evidence from landscape disturbance [PDF]
Journal of Animal Ecology, 2020 Natural and anthropogenic disturbances commonly alter patterns of biodiversity and ecosystem functioning. However, how networks of interacting species respond to these changes remains poorly understood.

Trophic Niche Differentiation in Rodents and Marsupials Revealed by Stable Isotopes. [PDF]
PLoS ONE, 2016 Tropical rainforests support the greatest diversity of small mammals in the world, yet we have little understanding about the mechanisms that promote the coexistence of species.

Intersexual trophic niche partitioning in an ant-eating spider (Araneae: Zodariidae). [PDF]
PLoS ONE, 2011 Divergence in trophic niche between the sexes may function to reduce competition between the sexes ("intersexual niche partitioning hypothesis"), or may be result from differential selection among the sexes on maximizing reproductive output ("sexual ...

Aquatic Biology, 2014 Food partitioning is one of the primary mechanisms facilitating the stable co-occurrence of competing species, but very few studies have investigated how food resource use of competing and closely related species varies with life-history stages and ...

The trophic niche of subterranean populations of Speleomantes italicus. [PDF]
Sci Rep, 2022 AbstractThe determination of a species trophic niche can clarify its functional role within a food web and how prey resources are used in relation with the spatial and temporal variability of environmental conditions. This information may result particularly useful for the implementation of conservation plans of endangered species having a cryptic ...

Ecological speciation in a generalist consumer expands the trophic niche of a dominant predator [PDF]
Scientific Reports, 2017 Ecological speciation – whereby an ancestral founder species diversifies to fill vacant niches – is a phenomenon characteristic of newly formed ecosystems. Despite such ubiquity, ecosystem-level effects of such divergence remain poorly understood.

Trophic niche partitioning in giant clams. [PDF]
Commun BiolEcosystems are influenced by competition for limited resources, a driver of niche partitioning. Over time, the emergence of novel traits facilitating new resource exploitation can reduce competition. However, additional layers of complexity, like symbiosis, complicate our understanding of the patterns shaping reef communities.

Parasite effects on host’s trophic and isotopic niches [PDF]
Trends in Parasitology, 2023 Wild animals are usually infected with parasites that can alter their hosts' trophic niches in food webs as can be seen from stable isotope analyses of infected versus uninfected individuals. The mechanisms influencing these effects of parasites on host isotopic values are not fully understood.
