英文摘要 | IntroductionFood web is an important basis for identifying trophodynamic processes, and evaluating the structural and functional characteristics of ecosystems. The trophodynamics and system function of artificial reef (AR) ecosystems have rarely been examined. MethodsStable isotope analysis was used to investigate the food web structure and functions of an artificial reef (AR) ecosystem in this study. Results and DiscussionThe delta 13C and delta 15N values of particulate organic matter (POM) in AR showed noticeable seasonal changes, and the delta 13C value of POM in autumn was significantly higher than that in other seasons (p<0.05). There were no significant seasonal variations in the delta 13C values of solid organic matter (SOM), and no significant difference between SOM and POM was observed except in autumn. Moreover, macroalgae did not significantly affect the delta 13C values of SOM. Phytoplankton may be the primary nutrient source in the AR ecosystem. The delta 13C values of most crustaceans in the AR were approximately between (-17.03 +/- 0.22) parts per thousand - (-17.74 +/- 0.07) parts per thousand, higher than those of most fish, indicating that they may have different basal nutrient sources. The trophic level (TL) of invertebrates was between 2.00 and 3.09, and that of fish was between 2.98 and 3.66. The distribution of delta 13C and TLs of crustaceans and fish showed that, except for crustaceans, bivalve shellfish and zooplankton might also be important food sources for fish in the AR ecosystem. ConclusionThe delta 13C and delta 15N values of most species in the AR showed good continuity, indicating that they may be mainly produced from the AR ecosystem. Migratory species such as Lateolabrax japonicus and Sepiella maindroni showed higher delta 13C values, indicating that they may have migrated from other sea areas. To maintain the stability of the ecosystem structure and function of the AR ecosystem, fishing activities should be carried out following the maximum sustainable yield theory. Future research needs to identify the nutritional relationship between AR and its adjacent sea areas, to depict the food web structure of the AR with higher accuracy. |
