Stable isotope signatures of primary producers display high inter-and intraspecific variation.
This is assigned to species-specific differences in isotope fractionation and variable abiotic …

Stable-isotope analysis (SIA) has revolutionized animal ecology by providing time-
integrated estimates of the use of resources and/or habitats. SIA is based on the premise …

Use of stable isotope techniques to quantify food web relationships requires a priori
estimates of the enrichment or depletion in δ15N and δ13C values between prey and …

Fatty acid–specific stable isotope analysis (FA‐SIA) is expected to encompass most of the
limits encountered when using more classical trophic markers such as bulk tissue stable …

The unit of stable isotope measures: at levels of natural abundance, stable isotopes are
measured using an isotope ratio mass spectrometer (IRMS). This instrument measures the …

Researchers will be able to use stable isotope analysis to study community structure in an
efficient way, without a need for extensive calibrations, if isotopic enrichment values are …

Abstract Knowledge of the diet source and trophic position of organisms is fundamental in
food web science. Since the 1980s, stable isotopes of light elements such as 13 C and 15 N …

Stable isotopes of carbon (δ 13 C) and nitrogen (δ 15 N) often have unique values among
lake habitats (eg benthic, littoral, pelagic), providing a widely used tool for measuring the …

Freshwater fish ecology has greatly benefited from the use of innovative tools such as stable
isotope analysis to determine the ecological effects of non‐native fishes. Stable isotope …

Stable isotopes of carbon and nitrogen are increasingly used in studies of animal diet
reconstruction via mixing models. However, isotope ratios of both consumer and source …
