Soil invertebrates, chemistry, weather, human management, and edaphic food webs at 135 sites in The Netherlands: SIZEWEB

This paper provides data on the taxonomy, abundance, body size, and general feeding habits of soil invertebrates
at 135 sites in the Netherlands, along with the edaphic chemical characteristics, air temperature, precipitation, atmospheric
deposition, and human management practices of those sites. Sampling, monitoring, and modeling activities were performed
in the framework of the Dutch Soil Quality Network. A total of 258 genera, families, and morpha of free-living soil
nematodes, mites, insects, myriapods, enchytraeids, and earthworms, ranging in dry body mass >7 orders of magnitude,
were identified, counted, and measured for biomass estimates. Trophic links reflecting life history were estimated from
existing literature and, when possible, compared with microarthropods’ carbohydrase activity. Environmental variables were
collected at each site, including soil chemistry (pH, carbon, nitrogen, phosphate, cadmium, chrome, copper, lead, mercury,
nickel, and zinc), atmospheric nitrogen deposition, inputs of nitrogen and phosphorus from manure, rainfall, and
temperature. Prior analyses of these data are cited, and the data are released here for the first time. These data describe how
strongly different types of human-induced disturbance influence the abundance–mass allometric relationships in soil biota. (Ecology 95(2) 2014)

本数据集涵盖荷兰135个样点的土壤无脊椎动物（soil invertebrates）分类学信息、丰度、体大小及一般取食习性，同时包含对应样点的土壤化学特性、气温、降水量、大气沉降及人类管理措施等相关数据。采样、监测与建模工作依托荷兰土壤质量网络（Dutch Soil Quality Network）框架开展。本次研究共鉴定、计数并测定了涵盖自由生活土壤线虫（free-living soil nematodes）、螨类（mites）、昆虫、多足类（myriapods）、线蚓类（enchytraeids）及蚯蚓（earthworms）在内的258个属、科及形态类群，其干体质量跨度超过7个数量级，相关数据用于生物量估算。基于现有文献估算了反映生活史特征的营养联系，并在条件允许时与小型节肢动物（microarthropods）的糖苷酶（carbohydrase）活性进行对比分析。各采样点均采集了环境变量数据，包括土壤化学指标（pH值、有机碳、全氮、磷酸盐、镉（cadmium）、铬（chrome）、铜、铅、汞、镍及锌）、大气氮沉降、粪肥输入的氮磷量、降雨量及气温。本研究引用了此前针对该数据集的分析成果，本次为该数据的首次公开发布。该数据集阐明了不同类型人为干扰对土壤生物群丰度-质量异速关系（abundance–mass allometric relationships）的影响强度。本数据源自《生态学》（Ecology）2014年第95卷第2期。
