摘要

While making investigations of glacial relic bryophytes in Belianske lúky mire, we recorded seasonal change in coverof selected bryophytes. It was decided to perform repeated monitoring between 2008-2010, in three replicates each year. Inparticular, the main observation was the decreasing cover of Campylium stellatum and Drepanocladus cossonii in thecourse of the year. In order to explain the seasonal change, we have sampled physico-chemical features of the examinedsites: pH, redox potential (ORP), conductivity, total dissolved solids (TDS), salinity, dissolved oxygen, chemical oxygendemand (COD), CaCO3, NO3-, SO42-, NH4+ and Cl-.Results show that within investigated sites the distribution of Campylium stellatum and Drepanocladus cossonii wasmostly limited by decreasing concentration of NH4+ and increasing concentration of NO3- in the course of the year. Thephylogenetic diversity of the bacterial community in the water sample from Belianske luky meadows was investigated usinga PCR of the 16S rRNA gene. After screening by Terminal Restriction Fragment Length Polymorphism (T-RFLP) method,we made in silico analysis, confirming the presence of nitrifying bacteria.The seasonal variation in bryophytes cover isinduced by the synergic influence of decomposition of organic substances in soils, by nitrifying bacteria activity and byunstable the water table.
