Species diversity changes of soil micromycetes in the tundra zone under impact of reindeer grazing
The impact of reindeer grazing on soil micromycetes of tundra biogeocenoses at different grazing pressure levels was studied. At strongly damaged places, dominating forms of soil fungi remained but species structure of micromycetes became poor due to disappearance of rare species. The decrease in species diversity was accompanied with an increase of CFUs (colony-forming units) of micromycetes. The presented data can be used for assessing the soil disturbance degree at reindeer pastures.
