TL;DR: In this article, the authors developed and discussed methods for generating an isotopic baseline and evaluate the assump- tions required to estimate the trophic position of consumers using stable isotopes in multiple ecosystem studies.

TL;DR: The results indicate that lipid extraction or normalization is most important when lipid content is variable among consumers of interest or between consumers and end members, and when differences in δ13C between end members is <10–12‰.

TL;DR: Building from extensive applications of stable isotope ratios by ecologists, the community-wide metrics may provide a new perspective on food web structure, function, and dynamics.

TL;DR: In this article, the authors developed an integrative framework for understanding the impact of detritus on food web dynamics, emphasizing the ontogeny and heterogeneity of detribus and the various ways that explicit inclusion of the detrital dynamics alters generalizations about the structure and functioning of food webs.

TL;DR: A comprehensive review of stable isotope analysis techniques, and a set of suggestions that transcend individual analytical approaches, are provided to help identify the most useful approaches to apply to a given data set.
