All animals face the possibility of limitations in food resources that could ultimately lead to
starvation-induced mortality. The primary goal of this review is to characterize the various …

Publisher Summary This chapter discusses isotopic methods used to track animal
movements. It highlights the use of stable isotope measurements as forensic tracers of origin …

Tracking Animal Migration with Stable Isotopes, Second Edition, provides a complete
introduction to new and powerful isotopic tools and applications that track animal migration …

Animals often show reduced reproductive success in urban compared to adjacent natural
areas. The lower availability and quality of natural food in cities is suggested as one key …

Stable isotope-based methods have proved to be immensely valuable for ecological studies
ranging in focus from animal movements to species interactions and community structure …

Stable isotopes are an important tool for physiological and behavioral ecologists, although
their usefulness depends on a thorough understanding of the dynamics of isotope …

The carbon isotope values in the exhaled breath of an animal mirror the carbon isotope
values of the metabolic fuels being oxidized. The measurement of stable carbon isotopes in …

Summary 1 The use of stable carbon (C) and nitrogen (N) isotopes (δ15N and δ13C,
respectively) to delineate trophic patterns in wild animals is common in ecology. Their utility …

Stable isotope analysis is an increasingly useful ecological tool, but its accuracy depends on
quantifying the tissue-specific trophic discrimination factors (TDFs) and isotopic …

Carbon turnover differs between tissues within an animal, but the extent to which
ecologically relevant increases in metabolism affect carbon turnover rates is largely …
