Data from: Important impacts of tissue selection and lipid extraction on ecological parameters derived from stable isotope ratios

1. The nitrogen (δ15N) and carbon (δ13C) isotope ratios of animal tissues can help identify the composition of diets and open up a myriad of ecological applications. However, consumers do not ingest or assimilate all components of food items, and it is not well understood how sampling different tissues of sources and consumers may affect isotopic values ascribed, and thereby how such variation affects derived ecological measures. 2. Utilising a simple prey–predator feeding relationship in...
