Changes in the global climate are seriously affecting biodiversity on a global scale. For Central Europe it was estimated that vegetation belts may shift up to several 100 km within the next decades (= potential range shift of the species). However, there is currently no information available if species can migrate fast enough to follow the potential range shifts. The main aim of this project is to predict realized range shifts for many (> 1000) Central European plant species in a modeling framework based on1. Shifts of potential species ranges derived from global change-driven ecological niche models 2. Seed dispersal kernels generated by process-based simulation models for anemochory, zoochory and dispersal by humans3. Migration rates based on seed dispersal kernels and demographic parameters4. Realized range shifts based on the current distribution and migration rates of the species The potential range shifts will be compared with realized range shifts for several IPCC scenarios and consequences for biodiversity will be analyzed.

全球气候的变化正在严重影响全球范围内的生物多样性。对于中欧，据估计，植被带可能会在未来几十年内移动高达几百公里（=物种的潜在范围移动）。然而，目前还没有关于物种是否能够以足够快的速度迁移以跟随潜在的范围变化的信息。该项目的主要目的是预测实现范围的变化，许多（> 1000）中欧植物物种的建模框架的基础上1。全球变化驱动的生态位模型得出的潜在物种范围的变化2。基于过程的风媒传播、动物传播和人类传播模拟模型生成的种子传播核心3。基于种子扩散核和人口参数的迁移率4。根据物种目前的分布和迁移率实现的范围转移将对潜在的范围转移与气专委几种情景下实现的范围转移进行比较，并将分析对生物多样性的影响。
