Abstract

The taxonomic features of the groups of nematode epiphytic mosses of three recreational parks of Chernigov city were studied.

The mosses were collected from the trunks of trees at the height 100–120 cm, and the mean sample was formed. The separation of nematodes was carried out by the funnel method of Baermann, exposition was 48 hours. The separated nematodes were fixed by TAP, and the temporal water-glycerine micropreparations were made. For the analysis of nematode fauna, the share of participation of each variety in fauna composition, frequency of occurrence, taxonomic richness (ST), Menhinik index of specific richness (DMn),, Berger-Parker index (d), Jakkard index(J), Sorencen index  (C),  Bongers maturity index  of nematode groups – MI were calculated.

There were revealed 40 varieties of nematodes that belong to 30 genera, 20 families and 8 orders. 12 (30 %) varieties of nematodes were found to be common for epiphytic mosses of all park zones. The value of Jakkard index between nematode complexes of studied parks didn’t exceed 0,48. In nematode groups the most numerous were representatives of Plectidae family.

It was established, that the condition of environment of nematodes of epiphytic mosses is the best at natural boundary “Kordivka” that is testified by the indices of richness (DMn was 1,80 against 0,71 and 0,62in other parks) and fauna diversityА (ST was 79 against 58 and 55), low level of dominance (d was 0,26 against 0,42 and 0,39), maturity of groups (MI was 3,18 against 2,27 and 2,58)
