Особенности сукцессионной смены микромицетов в процессе разложения растительного опада на вырубках среднетаежных еловых лесов

Abstract

The succession specificity of microscopic fungi during plant waste decomposition in non-disturbed spruce forests and deciduousconiferous cuttings of 2001/2002 has been studied. Complexes of micromycetes at cuttings largely differ from those in virgin forest communities — the Zhakkar index equals 0.29. The cutting misses numerous species of fungi which inhabit nondisturbed ecosystems. On the whole, species diversity of microscopic fungi at cuttings is 2.0 times as less than that in non-disturbed spruce forests. The variation limits of microbe biomass at different plant waste decomposition stages were identified. Biomass of microorganisms was structurally dominated by mycelium and fungal spores (98–99 % of total biomass). Total biomass of microorganisms at cuttings was normally 1.4 time as less than that at virgin.
