SBC LTER: BEACH: Invertebrate community structure and ecosystem functions of 24 sandy beach sites

These data result from a survey of 24 sandy beach sites in Santa Barbara and Ventura Counties in 2017 and 2018. We quantified marine macrophyte wrack subsidies, macroinvertebrates, and five ecosystem functions on three replicate transects at each site in order to elucidate the role of marine wrack subsidies on recipient ecosystem community structure and functioning. We also measured shorebirds at each site on three replicate survey days. Data are contained in four tables: 1) wrack cover and invertebrate community data by transect for each site used in our PiecewiseSEM model, 2) wrack cover and ecosystem function data by transect for each site used in our ecosystem multifunctionality estimate, 3) invertebrate species abundance and biomass by transect for each site, and 4) shorebird species abundance by survey date for each site.本数据集源自2017至2018年间对圣巴巴拉县（Santa Barbara）与文图拉县（Ventura）境内24处沙滩样地开展的野外调查。本研究在每个样地设置3条重复样带，对海洋大型植物碎屑输入（marine macrophyte wrack subsidies）、大型无脊椎动物（macroinvertebrates）群落及5项生态系统功能进行定量测定，以阐明海洋大型植物碎屑输入对受纳生态系统群落结构与功能的调控作用。此外，我们于每个样地开展3次重复调查，对滨鸟（shorebirds）种群进行监测统计。本数据集包含4张数据表：1）用于分段结构方程模型（PiecewiseSEM）分析的各站点每条样带的碎屑覆盖度与无脊椎动物群落数据；2）用于生态系统多功能性（ecosystem multifunctionality）评估的各站点每条样带的碎屑覆盖度与生态系统功能数据；3）各站点每条样带的无脊椎动物物种丰度与生物量数据；4）各站点按调查日期统计的滨鸟物种丰度数据。
