Stable isotope analysis has emerged as one of the primary means for examining the
structure and dynamics of food webs, and numerous analytical approaches are now …

Ecology Letters (2011) 14: 948–958 Abstract Many generalist populations are composed of
specialised individuals, whose niches are small subsets of the population niche. This …

The use of stable isotope data to infer characteristics of community structure and niche width
of community members has become increasingly common. Although these developments …

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

Apex predators are often assumed to be dietary generalists and, by feeding on prey from
multiple basal nutrient sources, serve to couple discrete food webs. But there is increasing …

Ecologists are increasingly using stable isotope analysis to inform questions about variation
in resource and habitat use from the individual to community level. In this study we …

We propose a framework for hypothesis‐testing of stable isotope ratios in ecological studies.
Statistical procedures are based on analysis of nested linear models and a residual …

Diets estimated from different proxies such as stable isotopes, stomach contents, and dental
microwear often disagree, leading to nominally well‐supported but greatly differing …

We investigated ontogenetic and seasonal changes in the feeding ecology of 2 small
pelagic fish species, the European anchovy Engraulis encrasicolus and the European …

The interpretation of isotopic data gathered in the field often demands knowing the rate at
which isotopes are incorporated into different tissues and species, and the discrimination …
