Stable isotope analysis (SIA) has proven to be a useful tool in reconstructing diets, characterizing trophic relationships, elucidating patterns of resource allocation, and constructing food webs. Consequently, the number of studies using SIA in trophic ecology has increased exponentially over the past decade. Several subdisciplines have developed, including isotope mixing models, incorporation dynamics models, lipid-extraction and correction methods, isotopic routing models, and compound…

Application of stable isotope analyses to avian diets and trophic structure

Its main applications in terms of conservation and management are reviewed: to assess the impacts of habitat change on the population reproduction, to detect the causes related to population dynamics, and to estimate the nutrient allocation of reproduction in the breeding ground compared with that in the wintering ground.

Toward a mechanistic understanding of trophic structure: inferences from simulating stable isotope ratios

This work built systems dynamic N-biomass-based models of different levels of complexity, containing explicit descriptions of isotope fractionation and of trophic level, and shows that there is no universal relationship between TL and δ15N that permits a robust prognostic tool for configuration of food webs even if all system components can be reliably analysed.

Stable isotopes and elasmobranchs: tissue types, methods, applications and assumptions.

The current state of SIA in elasmobranchs is reviewed, focusing on available tissues for analysis, methodological issues relating to the effects of lipid extraction and urea, the experimental dynamics of isotopic incorporation, diet-tissue discrimination factors, estimating trophic position, diet and mixing models and individual specialization and niche-width analyses.

Dual isotope assessment of trophic dynamics of an intertidal infaunal community with seasonal shifts in food sources

Using community-based statistics to quantitatively analyze stable isotope data can elucidate changes in food-web structure and imply that the feeding ecology of benthic infauna should be interpreted with caution and cannot be relied on buccal morphology alone.

Freshwater food web studies: a plea for multiple tracer approach

It is suggested that the simultaneous use of multiple tracers will provide more reliable results than any of them in isolation and the challenge is to develop methods to combine them enhancing their strengths and minimizing uncertainty.

Technological advances in stable isotope analysis provide ever more insights into animal ecology.

Whiteman et al. (2021) provide an excellent example of the power of CS-SIA using amino acid stable isotopes to quantify the extent of capital versus income breeding involved in emperor penguin egg production, and reframe an important life-history trait as a spectrum, rather than a dichotomy.

The potential of fatty acid isotopes to trace trophic transfer in aquatic food-webs

Evaluating the potential of FA-CSIA to provide high-resolution data on within-system energy flows using algae and zooplankton as model organisms reveals that the variability of FA isotope ratios provides a substantial challenge, but that FA- CSIA nevertheless have several promising applications in food-web ecology.



Effects of sample preparation on stable isotope ratios of carbon and nitrogen in marine invertebrates: implications for food web studies using stable isotopes

Guidelines for the standardization of sample preparation protocols for isotopic analysis are proposed both for large and small marine invertebrates and recommend avoiding both acid washing and DWR, and performing lipid extraction and gut evacuation in most cases.

Ten years of experimental animal isotopic ecology

Isotopic ecologists are just beginning to understand why 15 N biomagnifies along trophic chains, and to explore the factors that determine the degree of 15 N Biomagnification.


The use of stable isotopes to solve biogeochemical problems in ecosystem analysis is increasing rapidly because stable isotope data can contribute both source-sink (tracer) and process information:

The impact of metabolism on stable isotope dynamics: a theoretical framework

Dynamic energy budget (DEB) theory is extended with a limited set of new assumptions and rules in order to study the impact of metabolism on stable isotope dynamics in a mechanistic way and discusses how scenario analysis within this framework could help reveal common mechanisms across taxa.

Isotope trophic-step fractionation: a dynamic equilibrium model.

A linear model is developed to characterize the relationship between the equilibrium isotopic signature and the feeding rate influenced by isotopic discrimination during assimilation and excretion and predicts that parasitic organisms may be depleted relative to the tissues of their host.

Mass‐spectrometer bias in stable isotope ecology

Stable isotope analysis (SIA) is recognized as a powerful analytical tool with numerous ecological applications. This has been highlighted by the increase in popularity of the isotope ratio mass

Some theoretical aspects of isotope paleodiet studies

Can stable isotope ratios provide for community-wide measures of trophic structure? Comment.

The framework and metrics proposed by Layman et al. (2007a) are summarized, key limitations that prevent their widespread application are identified, and other directions that may facilitate the development of quantitative food web approaches using stable isotope data are discussed.

Stable isotope analysis of nutrient pathways leading to Atlantic salmon

Stable isotope ratios of carbon were particularly useful for illustrating seasonal changes in food resources of recently emerged age 0+ salmon as maternally derived marine carbon was subsequently diluted by freshwater carbon over the growing season.

Determination of aquatic food‐web structure based on compound‐specific nitrogen isotopic composition of amino acids

This study investigated the δ15N signatures of amino acids in 17 photoautotrophs and the trophic relationships during four controlled feeding experiments using green algae, zooplankton, and fish, implying that the amino acid method can be applied to a variety of organisms.
