Beyond trophic morphology: stable isotopes reveal ubiquitous versatility in marine turtle trophic ecology

Biological Reviews of The Cambridge Philosophical Society, 2019
The idea that interspecific variation in trophic morphology among closely related species effectively permits resource partitioning has driven research on ecological radiation since Darwin first described variation in beak morphology among Geospiza.

Trophic ecology of common elasmobranchs exploited by artisanal shark fisheries off south‑western Madagascar

Aquatic Biology, 2014
Knowledge of the trophic ecology and interactions of marine top predators is fundamental for understanding community structure and dynamics as well as ecosystem function.

There's no harm in having too much: A comprehensive toolbox of methods in trophic ecology

Food Webs, 2018
Trophic ecology is the study of feeding interactions and food acquisition by organisms. It includes the causes and consequences of those behaviours at all levels of biological organisation.

TROPHIC CIRCULATION IN ECOSYSTEMS/Circulación tróca en los ecosistemas

Ecosistemas y Recursos Agropecuarios, 2016
The trophic aspect of ecology has been studied for more than six decades; in this contribution we address theoretical aspects relative to the concept of trophic ow at the ecosystem level and from the thermodynamics point of view.

Spatial dietary differentiation and trophic variation in Gymnocypris chilianensis across three watersheds of the Hexi Corridor

Journal of Freshwater Ecology
Gymnocypris chilianensis is an endemic cyprinid fish distributed across three major watersheds – Shiyang, Heihe and Shule Rivers – within the Hexi Corridor on the northeastern Qinghai-Tibetan Plateau.

Trophic ecology of range-expanding round sardinella and resident sympatric species in the NW Mediterranean

Marine Ecology Progress Series, 2019
The recent northward expansion of the round sardinella Sardinella aurita in the Mediterranean Sea has been documented as a consequence of rising sea temperature.

A dataset on African bats’ functional traits

Scientific Data, 2023
Trait-based approaches are becoming extremely common in ecological modeling and the availability of traits databases is increasing. However, data availability is often biased towards particular regions and taxa, with many taxa (e.g., bats) often under ...

Dinner Time in the Atlantic Forest: Trophic Niche Partitioning of Two Sympatric Boana Species in the Southern Bahia State, Brazil

Acta Herpetologica
Understanding the ecological traits of species, such as dietary habits, is important for elucidating their natural history and ecological interactions.

Individual Specialization in a Generalist Apex Predator: The Leopard Seal

Ecology and Evolution
Apex predators are typically considered dietary generalists, which often masks individual variability. However, individual specialization—consistent differences among individuals in resource use or ecological role—is common in apex predators.

Diet and trophic ecology of the tiger shark (Galeocerdo cuvier) from South African waters

PLoS ONE, 2017
Knowledge of the diet and trophic ecology of apex predators is key for the implementation of effective ecosystem as well as species-based management initiatives.
