DOI: 10.1002/ece3.8742
Abstract: Abstract Documenting trophic niche partitioning and resource use within a community is critical to evaluate underlying mechanisms of coexistence, competition, or predation. Detailed knowledge about foraging is essential as it may influence the vital rates,… read more here.

Historical niche partitioning and long‐term trophic shifts in Laurentian Great Lakes deepwater coregonines
Sign Up to like & getrecommendations! Published in 2018 at "Ecosphere"
DOI: 10.1002/ecs2.2080
Abstract: Over the last 100 yr, anthropogenic stressors have decimated the assemblage of deepwater coregonines that once underpinned the food webs of the Laurentian Great Lakes. As a part of ongoing restoration efforts, fisheries managers are… read more here.

Trophic niche separation that facilitates co‐existence of high and low microbial abundance sponges is revealed by in situ study of carbon and nitrogen fluxes

DOI: 10.1002/lno.10546
Abstract: Sponges are commonly divided into high (HMA) and low (LMA) microbial-abundance species according to the bacterial biomass in their tissue. These two groups reflect distinct aquiferous structures and feeding strategies. In the NW Mediterranean coralligenous… read more here.

Trophic niches and feeding relationships of shorebirds in southern Brazil

DOI: 10.1007/s10452-018-9663-6
Abstract: Niche theory predicts that sympatric species should differ in some ecological characteristic, to allow co-existence and reduce competition for key resources. Food is critical on wintering grounds and stopover areas for migratory species that need… read more here.

DOI: 10.1007/s10750-019-3969-9
Abstract: Parallelism in trophic niches of polymorphic populations of Arctic charr was investigated in two similar subarctic lakes, Tårnvatn and Skøvatn, in northern Norway. Analysis of eleven microsatellite loci confirmed, respectively, the existence of three and… read more here.

Characterization of trophic niche partitioning between carp (Cyprinus carpio) and roach (Rutilus rutilus) in experimental polyculture ponds using carbon (δ13C) and nitrogen (δ15N) stable isotopes

DOI: 10.1016/j.aquaculture.2020.735162
Abstract: Abstract In temperate fish polyculture, common carp (Cyprinus carpio) and roach (Rutilus rutilus) are two fish species commonly reared in the same ponds. In the natural environment, these two species are considered omnivorous and may… read more here.

Ecological speciation in a generalist consumer expands the trophic niche of a dominant predator

DOI: 10.1038/s41598-017-08263-9
Abstract: 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. Here, we… read more here.

DOI: 10.1111/1365-2435.12978
Abstract: Abstract Invasive species can cause substantial ecological impacts on native biodiversity. While ecological theory attempts to explain the processes involved in the trophic integration of invaders into native food webs and their competitive impacts on… read more here.

DOI: 10.1139/cjfas-2020-0204
Abstract: Conceptually, trophic niche overlap and species abundance can describe the strength and number of interspecific trophic interactions to determine the competitive impact on reintroduced species or other ecosystem changes. We use an example with young-of-year… read more here.
