The influence of tamarisk (Meriones tamariscinus) and midday (M. meridianus) gerbils on soil biological activity in the Chernye Zemli, Kalmykia, was studied. Nitrogen fixation, denitrification, and CO2 emission were measured in soil samples from different parts of gerbil burrows. Functional biodiversity of the microbial community was evaluated using multisubstrate testing and comparison of bacterial group composition in samples from gerbil burrows. The impact of gerbils on soil biological… Expand
Biological activity of soils in the settlements of southern (Microtus rossiaemeridionalis) and bank (Clethrionomys glareolus) voles
The effect of voles on the biological activity of soddy-podzolic soil and agrozem manifested itself in increased intensity of aerobic and anaerobic destruction of organic matter and changes in the parameters of functional diversity of the microbial community of soils. Expand
Subterranean Desert Rodents (Genus Ctenomys) Create Soil Patches Enriched in Root Endophytic Fungal Propagules
The results show that food haulage, the deposition of excretions, and soil mixing by rodents’ burrowing promote soil patchiness by the enrichment in both types of root endophytic fungal propagules and changes in soil edaphic properties including moisture, field capacity, and texture. Expand
Desert Gerbils Affect Bacterial Composition of Soil
It is concluded that gerbils play an important role as ecosystem engineers within their burrow environment and affect the microbial complex of the nitrogen-fixing organisms in soils. Expand


Specific Features of Nitrogen Transformation in the Soddy-Podsolic Soil in the Colonies of the Common Vole Microtus arvalis
In the common vole colonies, the level of nitrogen fixation was reliably lower and that of denitrification higher, than in the control soil outside these colonies. Expand
[Dynamics of rodent community and populations in Kalmyk semideserts under decreasing pasture load and increasing humidity].
The difference between the observed and expected results provides evidence that rodent populations are somewhat "inert" in their response to changes in environmental conditions, and their development is relatively independent of these changes, but is contingent upon the state of populations in the past.
