Spatio-temporal variations in benthic and macrobenthic mol-luscs in Swan Lake, Shandong, China
摘要
Abstract
To understand the community structure as well as the spatial and temporal distribution of macrobenthic molluscs at different microhabitats in Swan Lake, we investigated the molluscan community and environmental factors at four types of microhabitats (Zostera japonica beds, bare area, edge of Zostera marina L. beds, and inte-rior of Z. marina L. beds) from December 2013 to November 2014. Fifteen molluscan species belonging to 14 families and 15 genera were recorded. The species composition, abundance, biomass, and biodiversity of molluscan communities exhibited significant differences among the transects but no clear difference among the seasons. The maximum abundance and biomass of molluscs were found in the bare area, whereas the minimum was found in the interior of Z. marina L. beds. The species diversity index of molluscs was higher in the Z. japonica beds and inter-nal Z. marina L. beds than in the other two transects. The dominant molluscs in the internal Z. marina L. beds were gastropod grazers, such as Chlorostoma rustica, Haloa rotundata, and Alaba picta. However, bivalve molluscs were more likely to choose the bare area without vegetation or the edge of Z. marina L. beds with sparse seagrass. Com-prehensive analysis revealed that the community structure and distribution of molluscs were closely related to sea-grass, sediment characteristics, and water depth.关键词
