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 of teeth and bones is regularly applied by archeologists and
paleoanthropologists seeking to reconstruct diets, ecologies, and environments of past …

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 …

Animals often consume resources from multiple energy channels, thereby connecting food
webs and driving trophic structure. Such 'multichannel feeding'can dictate ecosystem …

Food web ecology has revolutionized our understanding of ecological processes, but the
drivers of food web properties like trophic position (TP) and food chain length are notoriously …

Nitrogen isotope (δ15N) analysis of bulk tissues and individual amino acids (AA) can be
used to assess how consumers maintain nitrogen balance with broad implications for …

Herbivory is a dominant feeding strategy among animals, yet herbivores are often protein
limited. The gut microbiome is hypothesized to help maintain host protein balance by …

Discerning assimilated diets of wild animals using stable isotopes is well established where
potential dietary items in food webs are isotopically distinct. With the advent of mixing …

Lakes are recipients of allochthonous organic matter and nutrients. However, the importance
of these subsidies for food webs and how they vary with lake trophic status remains unclear …

Background Wildlife farming can be an important but complex tool for conservation. To
achieve conservation benefits, wildlife farming should meet a variety of criteria, including …
