Diatoms are among the most important primary producers in mountain lakes. However, the variables and mechanisms that govern the different aspects of diatom diversity are still poorly understood. Thus, this thesis investigated the patterns of sedimentary, littoral and planktic diatom diversity in 43 Tyrolian and Bavarian mountain lakes. Water temperature, nutrient level, spatial descriptors and species interactions governed diatom diversity. Community shifts could be mostly explained by direct human impacts.
