Spatial and interspecific variation in the food sources of sympatric estuarine nereidid polychaetes: stable isotopic and enzymatic approaches

Carbon and nitrogen stable isotope ratios (δ 13 C and δ 15 N) of sympatric nereidid polychaetes including Hediste diadroma , H. atoka , Tylorrhynchus osawai , and Simplisetia erythraeensis were examined at six stations along the Japanese coast to reveal the trophic niches of nereidid polychaetes in...
