Although mountain ecosystem are often considered relatively untouched, they encounter significant threats related to climate change, atmospheric depositions, increasing disturbances and biological invasions. In Europe, human pressure lasts for centuries and is considerably strong even in the highest parts of the mountains. Thanks to specific geological conditions and history, uppermost areas of Krkonose Mts., Czech Republic represent a particular ecosystem displaying affinities to both arctic and alpine tundra. Despite its small size, Krkonose served as a refuge for glacial relict species, and host many rare and endemic species, as well as rare geomorphologic components such as patterned grounds. At the same time, the area suffers from strong long-term human impact, starting already in the 16thcentury, and growing tourism with many the negative consequences. Because of steep environmental and climatic gradients, mountain ecosystems are especially sensitive to global change, still besides these distant effects, changes in mountain environment can also be attributed to the direct human influence such as disturbances, increased propagule pressure, changes in soil properties, and erosion. Disentangling the direct from indirect human effects and addressing the underlying mechanisms of changes remains a challenge. In my talk, I will discuss these mechanisms, focusing mainly on changes in soil properties and plant communities including facilitation of invasions. Long-term spatiotemporal changes are assessed using repeated field surveys, and historical/temporal remote sensing data. Findings from our study site are placed in a broader context within the global network of MIREN.


Coffee and cookies will be served at 11:45 outside S228.
