夏季辽东湾西部海域大型底栖动物群落结构与多样性
Community structure and diversity of macrobenthos in the western waters of Liaodong Bay during summer
摘要
Abstract
To understand community structure and biodiversity, macrobenthos at 15 sites in the western waters of Liaodong Bay were investigated in August, 2009. The survey was based on “Specifications for oceanographic sur-vey-Part 6: Marine biological survey (GB/T 12763.6-2007), ” and data analysis was realized by using the software PRIMER 5.0. A total of 124 species were identified in the research region. The average abundance of macrobenthos was (2824±1537) ind/m2, and the average biomass was (22.01±38.58) g/m2. The top three dominant species were Hemileucon bidentatus,Sigambra bassi, and Aricidea fragilis; the results were obtained by using the Index of Rela-tive Importance and Dominance Index. Similar distributions of the Shannon-Wiener index, Pielou’s evenness index, and Margalef’s richness index were also found in the research region, even though these values were lower in the estuary and middle waters than in the inshore and peripheral waters. Four macrobenthic community groups could be identified at a 50% similarity level according to CLUSTER, based on the average species abundances at all 15 sites. Results showed the research region to be unpolluted, and the examined bottom water parameters were found to have a weak influence on the macrobenthos community.关键词
