Sažetak
Mosses represent an important component of biodiversity, and their unique biology allows them to occupy specific ecological niche. The diversity of bryophytes is correlated with habitat heterogenity, diversity of present plant communities and available microhabitats within them. Mount Medvednica is characterised by well-preserved forests of different communities, which are primarily determined with the geological bedrock and altitude. Therefore, it can be expected that on Mt. Medvednica the diversity of moss flora follows the diversity of forest communities. In this research a total of 63 bryophyte species (51 species of Bryophyta and 12 species of Marchantiophyta) has been recorded on 13 plots in 6 forest communities. Double cluster analysis performed groups of species and plots, while correspondence analysis with passively projected vectors of mean values of Landolt' s ecological indices and measured soil pH showed clear distinction of bryoflora in thermophilous communities on calcareous bedrock (Tilio- Taxetum Glavač 1959 and Ostryo-Quercetum pubescentis (Horvat 1950) Trinajstić 1979) from bryophyte flora in forest communities developed on silicate bedrock (Hieracio racemosi- Quercetum petraeae Vukelić 1991, Festuco drymeiae-Abietetum Vukelić et Baričević 2007, Querco-Castanetum sativae Horvat 1938 i Luzulo luzuloidi-Quercetum (Hillitzer 1932) Passarge 1953) and their ecological dependence was explained. The main ecological factors that influence observed difference in the species composition among studied forest communities are substrate reaction, light and temperature. Communities developed on silicate bedrock are characterised by acidophilous, terricolous species, while neutrophilous, basophilous and bryophyte species of dry substrata are characteristic of forest communities on calcareous bedrock. Furthermore, observed variations in species number and composition on different plots in the same forest communities is due to the fact that bryophyte assemblage is greatly influenced with quality and quantity of available microhabitats.
