    Soil nematodes were studied in the alpine zone in the Tatra Mountains as a part of soil meso-cosmos transplant experiment. The aim of the experiment is to simulate the effects of elevated temperatures (by 1.5–3.0 °C) on soil chemistry, microbial communities and invertebrates by transplanting intact blocks of soil from higher to lower elevations. The study was done at three sites in the Furkotská dolina Valley of the Vyšné Wahlenbergovo Lake (VWL), which is a soil-poor catchment, and at two sites in the Veľká studená dolina Valley of the Starolesnianské Lake (SL) a soil-rich catchment, which are at between 2,200 and 1,760 m a. s. l. The first set of samples was collected in September 2013, when the soil meso-cosmoses were transplanted. The second set was collected in September 2014. Nematode assemblages were evaluated as reference data for comparing the assemblages in transplanted meso-cosmoses, which are to be analyzed in September 2015. A total of 105 species of nematodes were identified. On individual sampling dates the number of species varied from 29 to 58, number of genera from 19 to 33 and the total abundance of nematodes from 405 to 2,762×103 ind.m–2. Bacterivorous genera Plectus and Acrobeloides and omnivorous Eudorylaimus dominated (D≥4.5%) at almost all sites. Epidermal root feeder Aglenchus agricola was most abundant at sites at higher elevations (VWL1, VWL2 and SL1) while plant parasitic Helicotylenchus varicaudatus, Nagelus leptus and partly Paratylenchus microdorus were most abundant at the lowest elevation site SL2. Despite the variations in the abundance of different genera Cluster and Principal Components Analyses showed that nematode assemblages at higher elevations differed from those at lower elevations in both years. Maturity Index varied from 2.27 to 3.18 independent of the altitude of the sites.
