Coastal Biodiversity and Ecosystem Service Sustainability (CBESS) macrofaunal community metrics - total abundance (TA), total biomass (TB), species richness (SR), evenness (J) and community bioturbation potential (BPc) in mudflat and saltmarsh habitats

The dataset details total abundance (TA), total biomass (TB), species richness (SR) and evenness (J) [all based on abundance and biomass] and community bioturbation potential (BPc) across six intertidal sites in the winter and summer of 2013. The data provide metrics relating to the macrofaunal communities present within the top 10cm of sediment. Three sites were located in Essex, South East England and the other three in Morecambe Bay, North West England. Each site consisted of a saltmarsh habitat and adjacent mudflat habitat. 22 sampling quadrats were placed in each habitat covering four spatial scales. Three replicate cores of sediment were collected at each quadrat. They were sieved on a 0.5mm mesh and the macrofauna was removed, identified to species (or appropriate taxon) and individuals were identified to species (or most appropriate taxon), counted and weighed. The resulting abundance and biomass data were then used to calculate TA, TB, SR, J (based on abundance and biomass) and BPc. The data for mudflat habitats across Essex and Morecambe are complete, however, saltmarsh data is only available for one full Essex site (Tillingham Marsh), in one season (Winter) and across all sites, at the 1m scale. This data was collected as part of Coastal Biodiversity and Ecosystem Service Sustainability (CBESS): NE/J015644/1. The project was funded with support from the Biodiversity and Ecosystem Service Sustainability (BESS) programme. BESS is a six-year programme (2011-2017) funded by the UK Natural Environment Research Council (NERC) and the Biotechnology and Biological Sciences Research Council (BBSRC) as part of the UK's Living with Environmental Change (LWEC) programme.

本数据集详尽地记录了2013年冬季和夏季六个潮间带区域的总体丰度（TA）、总体生物量（TB）、物种丰富度（SR）及均匀度（J）（均基于丰度和生物量）以及群落扰动潜力（BPc）。数据涵盖了沉积物表层10厘米内的甲壳类动物群落的相关指标。数据采集地点分别位于英格兰东南部的埃塞克斯和西北部的莫克姆湾，每个地点均包含盐沼生境及其相邻的泥滩生境。在每个生境中，均放置了22个样方，覆盖四个空间尺度。在每个样方中，收集了三个重复的沉积物柱状样，并在0.5毫米的筛网上进行筛选，移除甲壳类动物，并对个体进行物种（或适当分类群）鉴定，计数并称重。据此得到的丰度和生物量数据，被用于计算TA、TB、SR、J（基于丰度和生物量）以及BPc。埃塞克斯和莫克姆湾的泥滩生境数据完整，然而，盐沼生境数据仅限于一个完整的埃塞克斯地点（蒂林厄姆湿地）的一个季节（冬季）以及所有地点的1米尺度。这些数据收集是作为海岸生物多样性和生态系统服务可持续性（CBESS）项目的一部分，项目编号为NE/J015644/1。该项目得到了生物多样性和生态系统服务可持续性（BESS）计划的支持。BESS是一项为期六年的计划（2011-2017），由英国自然环境研究委员会（NERC）和生物技术与生物科学研究所（BBSRC）资助，作为英国“与环境共存”（LWEC）计划的一部分。
