Considerable progress has been made in the development of statistical tools to quantify
trophic relationships using stable isotope ratios, including tools that address size and …

The relationship between food‐web structure (ie, trophic connections, including diet, trophic
position, and habitat use, and the strength of these connections) and ecosystem functions …

Woolly mammoth (Mammuthus primigenius), horse (Equus spp.) and bison (Bison spp.)
coexisted with a variety of mammalian megafauna across the Pleistocene mammoth steppe …

As human activities intensify, the structures of ecosystems and their food webs often
reorganize. Through the study of mesocosms harboring a diverse benthic coastal …

Mercury (Hg) is a ubiquitous toxic metal that biomagnifies in food webs, and can reach high
concentrations in top predators. Evaluating Hg biomagnification in Arctic marine food webs …

Stable isotope analyses have emerged as an insightful tool for ecologists, with quantitative
methods being developed to analyse data at the population, community and food web …

Central to the study of animal ecology is the usage an animal makes of its environment
(Johnson 1980). Animal populations need adequate quantities of usable resources to …

Changing climate is forcing many terrestrial and marine species to extend their ranges
poleward to stay within the bounds of their thermal tolerances. However, when such species …

The feeding ecology of two reef fishes associated with artificial reefs in the northwest Gulf of
Mexico (GoM) was examined using gut contents and natural stable isotopes. Reefs were …

Diet plasticity is a common behavior exhibited by piscivores to sustain predator biomass
when preferred prey biomass is reduced. Invasive piscivore diet plasticity could complicate …
