Pitfall traps Collembola morphospecies abundance in sub project 7 in KiLi project

Abundances of Collembola, resolution morphospecies. See "Collembola morphospecies in sub project 7 in KiLi project" for actual species names. Assemblages of springtails were sampled with pitfall traps. Ten pitfall traps were evenly spaced along two 50 m transects, with a distance of 10 m between individual traps and 20 m between transects. Pitfall traps were filled with 100-200 ml solution of equal parts of ethylenglycol and water with a drop of liquid soap to break the surface tension. The traps were placed on the sampling sites in June 2012 and collected after seven days. As the number of individuals collected in ten traps was very high and all individuals could not be analyzed in time, for the present analysis, we processed only three traps from each study site. Ground-dwelling beetles were sorted to morphospecies level, and where possible, to species. The KiLi project (2010-2018) is a German Science Foundation (DFG) funded research unit (DFG research unit FOR1246) that focuses on biodiversity and ecosystem processes along altitudinal and disturbance gradients on Mt. Kilimanjaro (Tanzania, Africa), capitalizing on its world-wide unique range of climatic and vegetation zones. The research unit comprises 2 central projects and 7 subprojects from various disciplines. On a total of 60 study sites in both natural and human-disturbed ecosystems biodiversity (e.g. plants, soil arthropods, ants, bees, frogs, lizards, bats, birds), related ecosystem processes (decomposition, seed dispersal, pollination, herbivory, predation), and biogeochemical processes and properties of ecosystems (climate, soil properties and nutrient status, regulation of water and carbon fluxes, trace gas emissions, primary productivity, functional diversity) are analyzed.弹尾纲（Collembola）个体丰度数据，按形态种（morphospecies）划分。实际物种名称详见《KiLi项目子课题7中的弹尾纲形态种》文档。 跳虫群落采用地面陷阱诱捕器（pitfall trap）采集。沿两条50米样带均匀布设10个诱捕罐，单个诱捕罐间距为10米，两条样带间距为20米。诱捕罐内注入100~200毫升乙二醇与纯水等体积混合的溶液，并添加1滴液体肥皂以降低溶液表面张力。诱捕器于2012年6月放置于采样点位，7天后回收。由于10个诱捕罐采集的个体数量极多，无法及时完成全部样本分析，因此本研究仅处理每个研究位点的3个诱捕罐样本。地表栖居甲虫被鉴定至形态种水平，条件允许时可鉴定至物种级。 KiLi项目（2010-2018年）是由德国科学基金会（Deutsche Forschungsgemeinschaft, DFG）资助的研究单元（DFG研究单元FOR1246），聚焦非洲坦桑尼亚乞力马扎罗山沿海拔与干扰梯度的生物多样性与生态系统过程，依托其全球独有的气候与植被带分布格局。该研究单元包含2个核心课题与7个跨学科子课题。在自然与人为干扰生态系统共60个研究位点中，研究人员将对生物多样性（涵盖植物、土壤节肢动物、蚂蚁、蜜蜂、蛙类、蜥蜴、蝙蝠、鸟类等）、相关生态系统过程（分解作用、种子传播、传粉服务、植食作用、捕食作用）以及生物地球化学过程与生态系统属性（气候特征、土壤属性与营养状况、水碳通量调控、痕量气体排放、初级生产力、功能多样性）展开系统分析。
