B1.2: MODELLING CLIMATE CHANGE-INDUCED SHIFTS IN ECOLOGICAL AND CLIMATIC NICHES FOR SELECTED MACROINVERTEBRATE SPECIES
B2.15: YOUNG RESEARCH GROUP "INTEGRATED MODELLING OF STREAM ECOSYSTEMS"
My primary research is the combination of different models to predict the impact of climate change on stream ecosystems, focusing on stream benthic invertebrates. The research is based on species distribution models (SDMs) at different spatial scales which are constantly improved e.g. by considering stream networks and actual water temperatures. In close cooperation with hydrologists we work on the integration of hydrological and hydraulic models into SDMs and the analysis how the incorporation of hydrological and habitat parameters may improve predictions. Besides analysis of species range changes or altitudinal shifts due to climate change these results are additionally used to estimate effects on ecological assessment results in Germany and Europe.
