| Abstract: | The structure of the microbial communities in the litters of middle-taiga bilberry-spruce forests was studied. It was found
that ammonifying and oligonitrophilic microorganisms predominate in these communities. Two maximums in the population density
of the microorganisms were observed in June and August. The number of microorganisms increased in the direction from the spruce
trunks to the periphery of the crowns. The species composition of the micromycetes in the litters under the spruce crowns
and within the intercrown spaces differed. The maximum population density of the fungi was found in the litter under the periphery
of the spruce crowns, whereas the maximum diversity of the micromycetes was observed within the intercrown spaces. The Trichoderma, Trichosporiella, Penicillium, Paecilomyces, and Chaetomium genera were most abundant in the litters of the bilberry spruce forests. The Penicillium genus had the maximum abundance during the entire growing period, and the amount of Mycelia sterilia increased in the fall. The maximum diversity of the fungi was observed in May and June. |
