Mollusc population abundance monitoring: Fall 2010 mid-marsh and creekbank infaunal and epifaunal mollusc abundance based on collections from GCE marsh, monitoring sites 1-10

This data set is the Fall 2010 estimate of infaunal and epifaunal mollusc abundance at the GCE-LTER marsh sites used for population monitoring. Species abundance was determined by hand-collecting all the infaunal and epifaunal molluscs from within quadrats of known area in mid-marsh and creekbank zones (n = 4 quadrats per zone) at all sites. The molluscs were returned to the lab, fixed in ethanol, transferred to and preserved in ethanol, counted and measured (size data is reported separately). The counts were converted to number per square meter. Gastropod species are listed first, followed by bivalve species. Size distribution data for these collections may be found in the GCE-LTER data set INV-GCEM-1101a2.本数据集为2010年秋季针对GCE-LTER盐沼监测站点的埋栖与表栖软体动物丰度估算结果，该站点用于种群动态监测。所有站点的软体动物丰度通过手工采样获取：在盐沼中部与溪岸带的已知面积样方内，采集全部埋栖与表栖软体动物（每个区域设置4个样方，n=4）。采集所得的软体动物被带回实验室，先用乙醇固定，随后转移并保存于乙醇溶液中，后续开展个体计数与形态测量工作，体长数据将单独发布。计数结果被换算为每平方米的个体数量。本数据集中腹足类物种优先列出，随后为双壳类物种。本次采集的体长分布数据可从GCE-LTER数据集INV-GCEM-1101a2中获取。
