Rich thanatocoenoses of mollusc shells accumulated in rivers and streams and on lake shores in North Eastern Alps had been sampled by F. Mahler. This collection deposited in the Museum of the Kremsmunster Abbey and supplemented by the author, includes 138 species of snails and bivalves found at 50 localities. Five of them represent the highest class of constancy, however different species are dominant components in particular thanatocoenoses. Death assemblages sampled along courses of two rivers distinctly differ from one another, while malacospectra characteristic of river and stream banks and lake shores are nearly the same. Apparently, the features of thanatocoenoses reflect random distribution of molluscs in a mosaic of mountain habitats, while in the man-impacted area they are controlled mainly by local conditions.
