1. Bound to the past: Historical contingency in aquatic microbial metacommunities
Sammanfattning : The composition of ecological communities differs due to a combination of different processes, which includes selection by local environmental conditions, dispersal from the regional species pool and random events. Additionally, historical processes such as past dispersal events may leave their imprint on communities as well, resulting in historically contingent communities. LÄS MER

4. Long-lasting ecological legacies of reindeer on tundra vegetation
Sammanfattning : Reindeer can have strong effects on the plant species composition and functioning of tundra ecosystems, and often promote a transition towards a graminoid-dominated vegetation type. As a result, they influence many ecological processes, such as nutrient dynamics, soil biotic composition and functioning, and carbon storage. LÄS MER
5. Quo vadis? Insights into the determinants of evolutionary dynamics
Sammanfattning : Predicting future evolutionary outcomes and explaining past and current patterns of biodiversity are fundamental goals in evolutionary biology. Trajectories of evolving populations are determined by evolutionary mechanisms (natural selection, mutation, genetic drift, and gene flow) and the environment in which the populations are found.
