Das Projekt "MOLAR: Messung und Modellierung der dynamischen Reaktion entlegener Bergseeoekosysteme auf oekologische Veraenderungen - ein Projekt der Bergseeforschung" wird vom Umweltbundesamt gefördert und von Universität Bern, Systematisch-Geobotanisches Institut durchgeführt. '- Study of relationship between climate records for mountain weather stations with those for lowland stations, - assessment of the physical, chemical, and biological seasonal variabbility of non-polluted remote lakes by intensive sampling and analysis - study of the relationship between the distribution of the primary biological constituents of mountain lake ecosystems that form the most important groups in the sediment cores (i.e. diatoms. chrysophytes, cladocera, chironomids and measured environmental summary variables, - study underlying trends and natural variability in climate from the fine-detail analysis of the uppermost sediment (last 200 years), - comparison of the sediment record with instrumental records of temperature and precipitation, - calibrate and validate the DYRESM and AQUASIM models and run these models using alternative scenarios for future climate.
