Trophic niche isotope analysis of the fish assemblages in a subtropical river, Southern China
River, 2023 Freshwater fishery resources in Chinese rivers have been markedly impaired as the results of overfishing, damming, and watershed development. However, little is known about trophic ecology of fish assemblages in the rivers of China. In this study, fishes

Trophic niche variation across the pan-Arctic coastal continuum. [PDF]
PLoS OneWe analyzed stable carbon and nitrogen isotope values (δ 13 C and δ 15 N, respectively) for pan-Arctic coastal primary producers and consumers to detect large-scale regional trends both temporally and spatially.

Not all jellyfish are equal: isotopic evidence for inter- and intraspecific variation in jellyfish trophic ecology [PDF]
, 2015 Jellyfish are highly topical within studies of pelagic food-webs and there is a growing realisation that their role is more complex than once thought.

Feeding and foraging ecology of Trindade petrels Pterodroma arminjoniana during the breeding period in the South Atlantic Ocean [PDF]
, 2017 Seabirds breeding in tropical environments experience high energetic demands, when foraging in an oligotrophic environment. The globally threatened Trindade petrel Pterodroma arminjoniana has its largest colony in Trindade Island (20°30′S–29°19′W) inside

Isotopic niche variability in macroconsumers of the East Scotia Ridge (Southern Ocean) hydrothermal vents: What more can we learn from an ellipse? [PDF]
, 2016 Aspects of between-individual trophic niche width can be explored through the isotopic niche concept. In many cases isotopic variability can be influenced by the scale of sampling and biological characteristics including body size or sex.

Direct and indirect effects of environmental factors on dietary niches in size-structured populations of a wild salmonid [PDF]
, 2015 Dietary plasticity of populations can be associated to ontogenetic diet preferences and depends on the size-structure of populations. Dietary niche characterizes the functional role of organisms in a food web, as it reflects both resources' diversity ...

Trophic niche of cave populations ofSpeleomantes 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). Adults displayed feeding activity from May to December and the Vacuity Index analysis revealed a discontinuous ...
