This malacological analysis was conducted at a site with peat and calcareous tufas in Łapsze Niżne, Podhale

(southern Poland). The study was carried out in 6 main and several complementary sections, in which 37 mollusc

species were recognized represented by almost 11 000 specimens. The study enabled the reconstruction of

environmental changes during the accumulation of the Holocene deposits (from the Boreal Phase till present).

Conclusions drawn from these reconstructions were compared with results of malacological and palynological

studies from other sites in Podhale. As a result, regional environmental reconstructions for the Holocene of the

area were made. The specific composition, ecological structure and succession of molluscan assemblages from

Łapsze Niżne indicate a significant role for local factors, thus demonstrating the variability of environmental

conditions within a geographic region.
