The proposed project aims at investigating how changes in land use and elevation affects the functional and phylodiversity of trees, ants and birds and how this translates into the associated processes in particular herbivory and predation. As it is time consuming to quantify these measures of biodiversity and processes we need a simple indicator system for routine monitoring across large areas. New developments in remote sensing provide promising information for predicting biodiversity as well as ecosystem processes. Spectral diversity derived from remote sensing is for example positively linked to biochemical diversity of trees. In addition, the vegetation reacts on subtle changes due to herbivory by detectable changes in netto primary production and leaf pigment status. Therefore, we expect that we can predict variables describing the status of biodiversity as well as certain processes by measures of spectral and structural diversity derived from remote sensing. This would provide the ground to develop a simple and integrative indicator for ecosystem services. Such an indicator system based on remote sensing would be an important step towards an integrative monitoring of the status of biodiversity, ecosystem functioning and finally ecosystem services that can be used across large areas and even in areas with rough terrains.

拟议的项目旨在调查土地利用和海拔的变化如何影响树木、蚂蚁和鸟类的功能和生物多样性，以及这如何转化为相关的过程，特别是食草动物和捕食。由于量化这些生物多样性和过程的措施是耗时的，我们需要一个简单的指标系统，用于大面积的日常监测。遥感方面的新发展为预测生物多样性和生态系统过程提供了有希望的信息。例如，从遥感得到的光谱多样性与树木的生物化学多样性正相关。此外，植被反应的微妙变化，由于草食动物的可检测的变化netto初级生产和叶色素的状态。因此，我们期望，我们可以预测变量描述的生物多样性以及某些过程的光谱和结构多样性的措施来自遥感的状态。这将为制定一个简单和综合的生态系统服务指标奠定基础。这种基于遥感的指标系统将是朝着综合监测生物多样性、生态系统功能以及生态系统服务的状况迈出的重要一步，可在大面积地区，甚至在地形崎岖的地区使用。
