北黄海褡裢岛海藻场邻近海域大型底栖动物群落结构及其与环境因子的关系

Community structure of macrozoobenthos and its relationship with environmental factors in the adjacent waters of Dalian Island seaweed beds in the North Yellow Sea

  • 摘要: 本文根据2020年5月(春季)和8月(夏季)对北黄海褡裢岛近岸海藻场邻近海域大型底栖动物的调查,研究了海藻盛衰季节大型底栖动物的群落结构特征及其与表层沉积物中海藻碎屑指示物质——总多酚含量在内的环境因子的关系。结果表明:两个季节共采集134种大型底栖动物,种类数为春季(94)<夏季(111),总平均生物量为春季(179.75 g/m2)>夏季(141.84 g/m2),而总平均丰度为春季(573.67 ind./m2)<夏季(647.50 ind./m2)。CLUSTER聚类分析表明,春季大型底栖动物群落可划分为3个群组,夏季则可划分为2个群组,两个季节间群落组成差异显著(Global R=0.031,P<0.05),造成季节间差异的主要贡献种类为紫蛇尾(Ophiopholis mirabilis)、尖顶大狐钩虾(Grandifoxus aciculata)、叶虾(Nebalia sp.)等。典型相关分析(CCA)表明,水深(F=13.9,P=0.002)、中值粒径(F=3.8,P=0.002)和底层水温(F=3.1,P=0.006)是影响大型底栖动物分布特征的主要驱动因子。此外,总多酚含量对大型底栖动物的影响存在种间差异:总多酚含量与短叶索沙蚕(Lumbrineris latreilli)、日本倍棘蛇尾(Amphioplus japonicus)、须鳃虫(Cirriformia tentaculata)、紫蛇尾等种类的丰度呈显著正相关(P<0.05),但与双管阔沙蚕(Platynereis bicanaliculata)、江户明樱蛤(Moerella jedoensis)、亮樱蛤(Nitidotellina sp.)等种类的丰度呈显著负相关(P<0.05)。

     

    Abstract: Based on the survey of macrozoobenthos in the adjacent areas of Dalian Island seaweed beds in the North Yellow Sea during May (spring) and August (summer) 2020, this paper analysed the community structure of macrozoobenthos during the seasons of macroalgae growing and decaying and its relationship with environmental factors including total polyphenol content, which is an indicator of macroalgal detritus in surface sediments. The results showed a total of 134 macrozoobenthos species were collected, with fewer species recorded in spring (94) than in summer (111). Total average biomass was greater in spring (179.75 g/m2) than in summer (141.84 g/m2), but the reverse was true for total average abundance, i.e. 573.67 and 647.50 ind./m2 in spring and summer, respectively. Based on CLUSTER analysis, the macrozoobenthos community could be divided into three groups in spring and two groups in summer. A significant difference in community composition was found between the two seasons (ANOSIM: Global R=0.031, P<0.05), which was mainly driven by Ophiopholis mirabilis, Grandifoxus aciculata and Nebalia sp.. Canonical Correlation Analysis (CCA) indicated, water depth (F=13.9, P=0.002), median sediment particle size (F=3.8, P=0.002) and bottom water temperature (F=3.1, P=0.006) were found to be the main driving factors influencing the macrozoobenthos community. In addition, differences were observed in the effects total polyphenol content had on individual species. A significant positive correlation was detected between total polyphenol content and the abundance of Lumbrineris latreilli, Amphioplus japonicus, Cirriformia tentaculata and Ophiopholis mirabilis (all P<0.05). However, a significant negative correlation was found between total polyphenol content and the abundance of Platynereis bicanaliculata, Moerella jedoensis and Nitidotellina sp. ( P<0.05).
