Spatial dietary shift of macrozoobenthos in a brackish lagoon revealed by carbon and nitrogen stable isotope ratios

Abstract

The food sources of 14 benthic consumer species (polychaetes, bivalves, amphipods and decapods) were investigated at 2 locations in a brackish lagoon (Gamo Lagoon, Japan) using carbon and nitrogen stable isotope ratios. Consumer diets were elucidated from the δ13C values of food sources, including riverine and terrestrial materials (
