Coleoptera Carabidae body size in pitfall traps in sub project 7 in KiLi project
收藏资源简介:
There are still some unsolved qustions regarding plot level information, but means per Carabid species are available. Abacetus spec., Afrotarus kilimanus, Neosipelus sp. 1 and sp 2., Tyronia lateralis and Tyronia spec. nov. - measurements are available, but without information for the plot. Assemblages of ground-dwelling beetles were sampled with pitfall traps8. 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.
目前关于样方水平的信息仍有部分尚未解决的问题,但步甲(Carabid)物种的均值数据已可获取。阿巴步甲属未定种(Abacetus spec.)、基里曼贾非澳步甲(Afrotarus kilimanus)、新细颈步甲属物种1与物种2(Neosipelus sp. 1、sp. 2)、侧形泰罗步甲(Tyronia lateralis)以及泰罗步甲新种(Tyronia spec. nov.)均有测量数据,但缺乏对应样方的相关信息。 本研究采用陷阱诱捕器[8]采集地表甲虫群落。沿两条50米样带均匀布设10个陷阱诱捕器,单个诱捕器间距为10米,样带间距为20米。陷阱诱捕器内注入100-200毫升乙二醇与纯水等体积混合的溶液,并添加1滴液态肥皂以降低表面张力。诱捕器于2012年6月放置于采样点,7天后回收。由于10个诱捕器采集到的甲虫个体数量极多,无法及时完成全部样本的分析,因此本次分析仅处理每个研究站点的3个诱捕器样本。地表甲虫被鉴定至形态种(morphospecies)级别,若条件允许则鉴定至物种水平。 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),其核心研究方向为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,依托该山地全球独有的气候与植被带分布特征开展研究。该研究单元包含2个核心项目与7个跨学科子项目。研究共覆盖60个研究站点,涵盖自然与受人类干扰的生态系统,对生物多样性(如植物、土壤节肢动物、蚂蚁、蜜蜂、蛙类、蜥蜴、蝙蝠、鸟类)、相关生态系统过程(分解作用、种子传播、传粉、植食作用、捕食作用)以及生态系统生物地球化学过程与属性(气候、土壤特性与营养状况、水碳通量调控、痕量气体排放、初级生产力、功能多样性)进行分析。
