| contents | Community Structure and Influencing Factors of Macro-Benthos in Bottom-Seeded Marine Pastures: A Case Study of Caofeidian, China. Xue, Xiangping Yun, Long Sun, Zhaohui Zan, Jiangwei Xu, Xinjing Liu, Xia Gao, Song Wang, Guangyu Liu, Mingshuai Si, Fei To accurately assess the water quality, ecosystem status, distribution of large benthic organisms, and ecological restoration under human intervention, an analysis of benthic organisms on Caofeidian in September and November 2023 and January and May of the following year was conducted in this work. By performing CCA (canonical correspondence analysis) and cluster and correlation coefficient (Pearson) analyses, the temporal variation characteristics of benthic abundance, dominant species, community structure and biodiversity were analyzed. A total of 79 species of macro-benthic animals were found in four months, including 32 species of polychaetes, cnidarians, 1 species of Nemertean, 19 species of crustaceans, and 24 species of molluscs. The use of conventional grab-type mud collectors revealed that the dominated the survey ( > 0.02). While only a small number of were collected from bottom-dwelling species, a certain number of bottom-dwelling species ( and ) were also collected during the trawl survey. Additionally, a significant population of was found in the area. It is speculated that the dual effects of predation and competition are likely the primary reasons for the relatively low abundance of bottom-dwelling species. The density and biomass of macro-benthos were consistent over time, which was the highest in May, the second highest in January, and the lowest in September and November. The main environmental factors affecting the large benthic communities in the surveyed sea areas were pH, DO, NO-N, T, SAL and PO-P. Combined with historical data, it was found that although the environmental condition in the Caofeidian sea area has improved, the has been dominant. In addition, the abundance of other species is much less than that of the , and the diversity of the benthic community is still reduced. Our work provides valuable data support for the management and improvement of bottom Marine pasture and promotes the transformation of Marine resources from resource plunder to a sustainable resource. |
