Trophic importance of benthic microalgae to macrozoobenthos in coastal bay systems in Korea:dual stable C and N isotope analyses
The role of benthic microalgae as the source of primary organic matter for the macrozoobenthos community was examined in 3 bay systems of the south coast of the Korean peninsula using stable carbon and nitrogen isotope ratios (delta(13)C and delta(15)N) as a dual tracer. The delta(13)C and delta(15)...

The role of benthic microalgae as the source of primary organic matter for the macrozoobenthos community was examined in 3 bay systems of the south coast of the Korean peninsula using stable carbon and nitrogen isotope ratios (delta(13)C and delta(15)N) as a dual tracer. The delta(13)C and delta(15)N of riverine particulate inputs, primary producers and macrozoobenthos collected from the intertidal and subtidal habitats of the bays were measured and compared with those from adjacent offshore waters. Extensive intertidal flats occurred with wide marsh plains (primarily Phragmites australis) at the uppermost part of the intertidal zone in all 3 bay systems, but different hydrologic features were exhibited among bay systems. There were no systematic variations in delta(13)C for the same plant taxa, but different producer groups were clearly separated by their delta(13)C values. Benthic microalgae and macroalgae, which had similar delta(13)C values, were separated by their delta(15)N values. The VC values of macrozoobenthos collected from the offshore areas were similar to those of phytoplankton. Macrorzoobenthos collected from all 3 bay habitats had simila delta(13)C ranges, and their delta(13)C values (means of all consumers, feeding types and species) were less negative than those of the offshore macrozoobenthos.
