Differences in trophic structure and trophic pathways between artificial reef and natural reef ecosystems along the coast of the North yellow Sea, China, based on stable isotope analyses

Artificial reefs have been employed to promote enrichment of degraded habitats communities and support local fisheries. To better evaluate the performance of artificial reefs, simultaneous comparisons with relatively undisturbed natural reefs nearby are essential. With the inclusion of the stable is...

description	Artificial reefs have been employed to promote enrichment of degraded habitats communities and support local fisheries. To better evaluate the performance of artificial reefs, simultaneous comparisons with relatively undisturbed natural reefs nearby are essential. With the inclusion of the stable isotope method to characterize and compare ecosystem functioning for two reef systems, both trophic structure and trophic flow at an artificial and at a nearby natural reef are evaluated in the present work. We found that: 1) both macrobenthos and fish can be clustered into five trophic groups for each site, with similar grouping configurations in trophic structures, and 2) energy pathways both from basal resources to macrobenthos and from macrobenthos are similar between the artificial reef and the natural reef, although the pathway magnitudes may be spatially different.
