The development of the isotopic niche, an n-dimensional hypervolume (with n being the
number of isotopes) occupied by a population in delta space, has revolutionized the study of …

Robustly quantifying dietary resource use and trophic position using stable isotopes
requires accurate trophic discrimination factors (TDF; Δ13C and Δ15N for carbon and …

Stable isotope analysis provides a powerful tool to identify the energy sources which fuel
consumers, to understand trophic interactions and to infer consumer trophic position (TP), an …

Identifying the composition of avian diets is a critical step in characterizing the roles of birds
within ecosystems. However, because birds are a diverse taxonomic group with equally …

Stable isotope analysis is increasingly being used to assess diet and trophic positions of
animals. Such assessments require estimates of trophic discrimination factors (TDFs)—offset …

Stable isotope analysis (SIA) is widely used to assess animal diet and movements, requiring
accurate estimates of trophic discrimination factors (TDFs). Since TDFs are only available for …

Aquatic and terrestrial ecosystems are connected through reciprocal fluxes of energy and
nutrients that can subsidize consumers. Past research on reciprocal aquatic–terrestrial …

The broad negative consequences of habitat degradation on biodiversity have been studied,
but the complex effects of natural–agricultural landscape matrices remain poorly …

Ecologists quantify animal diets using direct and indirect methods, including analysis of
faeces, pellets, prey items and gut contents. For stable isotope analyses of diet, Bayesian …

Dietary intake, drinking behavior, and physiology together influence the isotopic composition
of herbivore tooth enamel, but the degree to which these factors influence the sequence of δ …
