River and Conservation Research Group

The Research Group River and Conservation focuses on running waters in alpine and polar regions, their crucial role in alpine landscapes, in the quality of lowland rivers and in the generation of a limiting resource, i.e. water and energy. Within this context we study benthic animal communities as indicators of climate change and coordinate currently three research projects in these cold environments. Besides applying general biological criteria and indices, we developed and defined biological, ecological and behavioral species traits to be used to detect and describe climate and environmental change. Within these projects, we elaborate methodological guidelines for a long-term monitoring on running water ecosystems, especially in high altitudes and latitudes. Recent emphasis in these cold environments is also put on food availability and food web structure, where we apply methods established in earlier works, including C and N stable isotope analyses. Riverine ecosystems in the Alps are highly under stress. In two Alpine Space research projects, therefore, we concentrate on riverine landscapes, environmental conditions and habitat fragmentation. Based on all available data on selected riverine plant and animal species, we identify typical habitats and correlate them with landscapes elements and barriers being effective in the longitudinal, lateral, vertical and temporal dimensions of river systems. A long-standing interest within the group is the ecology of freshwater crayfish, including their distribution, habitat requirements and threats.
