Task 4.3.3. Assessing stability of ecological communities

Task lead: Martin Zobel, University of Tartu, Estonia

We tested the stability of ecological communities by addressing compositional and functional structure of plant communities either in spatially separated dynamic stages of communities, in model systems undergoing climate change, or in permafrost samples of different age. In particular, we tested the community stability with three empirical datasets. The first dataset comprised understory vegetation of mixed coniferous boreonemoral forest in central Estonia (both plants and arbuscular mycorrhizal fungi were addressed). The second dataset comprised grassland vegetation in Swiss alps along a large elevation gradient (from 400 m to 3200 m). We recorded different degree of habitat filtering and niche limitation in these systems. The third dataset comprises permafrost samples from different locations, covering approximately the 40,000 year period and analyzed for ancient DNA by A2 team. The analysis of this dataset is still in progress.
