Stable isotopes are quantitative indicators of trophic niche. [PDF]
Ecol Lett, 2019 AbstractHette‐Tronquart (2019, Ecol. Lett.) raises three concerns about our interpretation of stable isotope data in Sheppard et al. (2018, Ecol. Lett., 21, 665). We feel that these concerns are based on comparisons that are unreasonable or ignore the ecological context from which the data were collected.

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.

Sources of intraspecific variation in the isotopic niche of a semi-aquatic predator in a human-modified landscape [PDF]
PeerJ, 2023 Intraspecific variation modulates patterns of resource use by species, potentially affecting the structure and stability of food webs. In human-modified landscapes, habitat disturbance modifies trophic interactions and intraspecific niche variation ...

Trophic strategies explain the ocean niches of small eukaryotic phytoplankton [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2022 A large fraction of marine primary production is performed by diverse small protists, and many of these phytoplankton are phagotrophic mixotrophs that vary widely in their capacity to consume bacterial prey. Prior analyses suggest that mixotrophic protists as a group vary in importance across ocean environments, but the mechanisms ...

Diversity, 2022 Rockfish (genus Sebastes) assemblages can inform mechanisms of coexistence and maintenance of diversity in ecological communities. Coexistence theory characterizes ecological assemblages as following either a deterministic niche differentiation model, or

Frontiers in Ecology and Evolution, 2021 According to the niche variation hypothesis (NVH), the populations with wider niches are phenotypically more variable than those with narrow niches. Giller expanded the NVH, suggesting that the niche width, morphological variation, and genetic 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 ...

Mechanisms of trophic niche compression: Evidence from landscape disturbance [PDF]
Journal of Animal Ecology, 2018 Abstract 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 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
