Comparison of 13C and 15N discrimination factors and turnover rates between congeneric crayfish Orconectes rusticus and O. virilis (Decapoda, Cambaridae)

Abstract

Ecological applications of stable isotope analysis are dependent on knowing consumer-diet discrimination factors (Δ) and consumer metabolic turnover rates (m). We used an 80-day laboratory experiment to test for differences in the δ13C, δ15N and m of two species of crayfish (Orconectes rusticus and O. virilis) fed one of two diets (algae wafers and… (More)
