Stable isotope analysis (SIA) has proven to be a useful tool in reconstructing diets,
characterizing trophic relationships, elucidating patterns of resource allocation, and …

Fifty years ago, GE Hutchinson defined the ecological niche as a hypervolume in n‐
dimensional space with environmental variables as axes. Ecologists have recently …

Stable isotope analysis (SIA) has emerged as a common tool in ecology and has proven
especially useful in the study of animal diet, habitat use, movement, and physiology. SIA has …

Stable isotopes are a powerful tool for ecologists, often used to assess contributions of
different sources to a mixture (eg prey to a consumer). Mixing models use stable isotope …

Abstract We open this Special Feature on stable isotopes in mammalian research with a
beginner's guide, an introduction to the novice and a refresher to the well-versed. In this …

About 10 years ago, reviews of the use of stable isotopes in animal ecology predicted
explosive growth in this field and called for laboratory experiments to provide a mechanistic …

A common use of stable isotope analysis in mammalogy is to make inferences about diet
from isotope values (typically δ13C and δ15N) measured in tissues and food sources of a …

Estimating trophic structures is a common approach used to retrieve information regarding
energy pathways, predation, and competition in complex ecosystems. The application of …

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 …

Using stable isotope mixing models (SIMMs) as a tool to investigate the foraging ecology of
animals is gaining popularity among researchers. As a result, statistical methods are rapidly …
