In the present study, the aquatic mollusc colonization of eight mountain lakes located in the Hohe Tauern (Eastern Alps, Austria) was investigated. From a geographic point of view, three of the investigated lakes can be assigned to the upper montane altitude level, ranging from 1000 to 1400 msm, while the other five lakes belong to the subalpine altitude level (1400 to 2200 msm). Altogether, eight species of freshwater snails and five species of bivalves were collected during the field study. The investigation clearly shows that, besides the diversity of species, also the number of individuals per species declines significantly with increasing sea level. Above 2000 msm, the population density of a single species usually drops below I individual per m2. Seven of the 13 species belong to the Red List of threatened animals in Austria, and some of them are already highly endangered (Anisus spirorbis, A. leucostoma)
