Participative Spatial Scenario Analysis for Alpine Ecosystems
Land use and land cover patterns are shaped by the interplay of human and ecological processes. Thus, heterogeneous cultural landscapes have developed, delivering multiple ecosystem services. To guarantee human well-being, the development of land use types has to be evaluated. Scenario development and land use and land cover change models are well-known tools for assessing future landscape chan...
متن کاملRecent climate extremes alter alpine lake ecosystems.
Here, we show that alpine lake ecosystems are responsive to interannual variation in climate, based on long-term limnological and meteorological data from the Canadian Rockies. In the 2000s, in years with colder winter temperatures, higher winter snowfall, later snowmelt, shorter ice-free seasons, and dryer summers, relative to the 1990s, alpine lakes became clearer, warmer, and mixed to deeper...

15 صفحه اولBiodiversity and Funtioning of Selected Terrestrial Ecosystems: Alpine and Arctic Ecosystems
Ecosystem integrity on steep mountain slopes and in high elevation landscapes is in general a question of soil stability, which in turn depends on plant cover and rooting patterns. Terrestrial net primary production and decomposition rates in arctic and alpine ecosystems are low and revegetation after human disturbance can take centuries. Relatively few species regulate the annual input and los...
