The aimed project is regarded as logical consequence to combine and integrate the hitherto own project activities and results in a final issue of regional as well as principal relevance for the mountain rainforest ecosystems in southern Ecuador. Three goals build up the framework of the intended project: (i) to continue the climate measurement (including service for other WGs) and to identify important climate change triggers for plant diversity changes by “extreme event analyses”; (ii) to close the missing link between natural, nature-near, and anthropogenic vegetation by detecting the elevational distribution of the occurring vascular terrestrial plant species on pastures, abandoned sites, and trails; (iii) to repeat the mapping of the landslides 10 years after a first equivalent procedure by the first applicant’s WG and to revisit the landslide vegetation investigated in 2002 to redetermine the related succession traits. While the majority of research on climate change impacts on biodiversity regards linear trends non-linear processes are mostly ignored. Hence, the requested project focuses on plant diversity responses on collateral events given by climate induced disturbances or stress such as droughts or sliding and by species invasions from man-made environs.

目标项目被认为是联合收割机和整合迄今为止自己的项目活动的必然结果，并导致了对厄瓜多尔南部山区雨林生态系统具有区域和主要相关性的最后一个问题。三个目标构成了预期项目的框架：（i）继续气候测量（包括为其他工作组提供服务），并通过“极端事件分析”确定植物多样性变化的重要气候变化触发因素;（ii）通过检测牧场上现存的陆生维管植物物种的海拔分布，弥补天然植被、近自然植被和人为植被之间缺失的联系，（iii）在第一个申请人的工作组进行第一次同等程序后10年，重新绘制滑坡图，并重新访问2002年调查的滑坡植被，以重新确定相关的演替特征。虽然大多数关于气候变化对生物多样性影响的研究关注线性趋势，但非线性过程大多被忽视。因此，所请求的项目侧重于植物多样性对干旱或滑坡等气候引起的干扰或压力以及人为环境物种入侵造成的附带事件的反应。
