Diet‐tissue isotopic fractionation of carbon (C) and nitrogen (N) isotopes in short‐and longer‐
term diet integrators of diet (ie, blood serum and red cells), that involve non‐invasive …

The stable carbon isotopic composition (expressed as δ13C) of herbivore remains is
commonly used to reconstruct past changes in the relative abundance of C4 versus C3 …

In African savannas, browse-based resources (C3 plants) are isotopically distinct from
grasses (C4 plants). The carbon isotopic composition of the basic plant diet is recorded in …

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

Isotopic discrimination and turn-over are fundamental to the application of stable isotope
ecology in animals. However, detailed information for specific tissues and species are …

Stable-isotope analysis (SIA) has revolutionized animal ecology by providing time-
integrated estimates of the use of resources and/or habitats. SIA is based on the premise …

We measured stable carbon (13C/12C) and nitrogen (15N/14N) isotope ratios in nail,
whiskers, skin, hair, and blood of captive harp seals (Pagophilus groenlandicus), harbour …

This paper characterizes predator–prey interactions amongst African mammals from C 4
savanna environments using stable carbon and nitrogen isotope proxies for diet. Stable …

Objectives Stable isotope data provide insight into the reconstruction of ancient human diet.
However, cooking may alter the original stable isotope compositions of food due to losses …

Stable isotope analysis of carbon and nitrogen in hair provides a versatile tool for
reconstructing feeding behavior in elusive primate species. Particularly in great apes …
