Understanding rates of isotopic incorporation and discrimination factors between tissues
and diet is an important focus of ecologists seeking to use stable isotopes to track temporal …

Carbon and nitrogen isotope ratios in hair sampled from 65 communities across the central
and intermountain regions of the United States and more intensively throughout 29 ZIP …

Omnivorous animals feed on several food items that often differ in macronutrient and
isotopic composition. Macronutrients can be used for either metabolism or body tissue …

Breath and diet samples were collected from 29 taxa of animals at the Zurich and Basel
Zoos to characterize the carbon isotope enrichment between breath and diet. Diet samples …

Stable isotope ratio analysis (SIRA) was used as an analytical tool to verify the preslaughter
diet of beef cattle. Muscle and tail hair samples were collected from animals fed either …

Summary 1 Mammals usually derive energy from metabolizing fat and glycogen stores
combined with exogenous food. Nectarivorous bats mostly consume a diet low in both fat …

Recently, Caut, Angulo & Courchamp (2009, Journal of Applied Ecology) published a review
on diet‐tissue isotopic shifts in animals. They concluded that diet‐tissue shifts are influenced …

Along food chains, ie, at different trophic levels, the most abundant taxa often represent
exceptional food reservoirs, and are hence the main target of consumers and predators. The …

The stable isotope composition of carbon and nitrogen in feces can be a useful tool for
reconstructing diet. To examine whether the isotopic composition of feces reflect those of …

We propose a hypothesis for digestive constraints on the browsing and grazing options
available to ruminants: that the diet-niche range (maximum and minimum grass intake) of a …
