Isotopic niche is not equal to trophic niche
Ecology Letters, 2019 International audienceThe work of Sheppard et al. (Ecol. Lett., 21, 2018, 1395) relies on the strong assumption that isotopic niche is equal to trophic niche.

Trophic niche of cave populations of Speleomantes italicus [PDF]
Journal of Natural History, 2006 This paper investigates the trophic niche of a poorly studied cave salamander, Speleomantes italicus. We examined Central Appennine hypogean populations that inhabit seven caves situated in three limestone areas in Umbria Region (Italy).

Food webs and the dimensionality of trophic niche space [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 1977 If the trophic niche of a kind of organism is a connected region in niche space, then it is possible for trophic niche overlaps to be described in a one-dimensional niche space if and only if the trophic niche overlap graph is an interval graph. An analysis of 30 food webs, using the combinatorial theory of interval graphs, suggests that a niche space ...

Divergence in the trophic niche of sympatric freshwater invaders
Biological Invasions, 2013When present in sympatry, invasive species have the potential to amplify or mitigate their ecological impacts through their trophic interactions. Their trophic niches may overlap, limiting impacts to specific trophic levels or functional groups; alternatively, they may diverge, with this niche differentiation resulting in contrasting impacts between ...

Collapse of trophic-niche structure in belowground communities under anthropogenic disturbance
Ecosphere, 2018 The niche concept is a central paradigm in ecology, but empirical evidence on how the niche structure of belowground communities is affected by ecosystem disturbance is lacking.

Trophic niche and habitat shifts of sympatric Gerreidae
Journal of Fish Biology, 2014The diet and mouth growth rates of three Gerreidae species (Eugerres brasilianus, Eucinostomus melanopterusandDiapterus rhombeus) were assessed at different ontogenetic phases (juveniles, sub‐adults and adults) in order to detect allometric growth, and whether they are related to habitat and seasonal changes in the Goiana Estuary, north‐east Brazil ...

Interpopulation trophic niches and ontogenetic shifts of a mangrove fish predator
Journal of Fish Biology, 2022AbstractFish trophic niches reflect important ecological interactions and provide insight into the structure of mangrove food webs. Few studies have been conducted in mangrove fish predators to investigate interpopulation trophic niches and ontogenetic shifts.

Trophic niche width, offspring condition and immunity in a raptor species
Oecologia, 2013Strategies developed by organisms to maximize foraging efficiency have a strong influence on fitness. The way in which the range of food resources is exploited has served to classify species, populations and individuals from more specialist (narrow trophic niche) to more generalist (broad trophic niche).
