Abstract:
... The steppe zone occupies large area in the South of the European Russia. Part of the Caspian Lowland belongs to the desert zone. Some researchers distinguish the semidesert zone along with the steppe and desert zones. The paradox is that there is no semidesert type of vegetation, there are no typical elements for the semidesert, but the semidesert is considered as a separate zone. ...

Abstract:
... Despite the importance of decomposition for biogeochemical cycles, it is still not clear how this process is affected by different forms of nitrogen (N). Equal amounts of N with different ratios of inorganic N: organic N (0 : 0, 10 : 0, 7 : 3, 5 : 5, 3 : 7, and 0 : 10) were added to the soil in a steppe. We studied the response of litter decomposition to different forms of N enrichment. The treatm ...

Abstract:
... The process of blowing snow is important for secondary distribution of water resources in seasonal grassland snow areas because it affects the regeneration, growth, and nutrient circulation of vegetation. This study conducted field observations of blowing snow and snow accumulation in a grassland area typical of northern China. The results showed that in the near-surface area (0 to 100 cm), snow d ...

Abstract:
... Evidence is mounting that the structures of trophic networks are governed by migratory movements of interacting species and also by their phylogenetic relationships. Using the largest available trophic network of a large steppe ecosystem, we tested that steppe trophic networks including migratory species are associated with (i) migratory strategy and (ii) phylogenetic relatedness of interacting sp ...

Abstract:
... Clonal plants with diverse growth forms are dominant in plant community of temperate grasslands and sensitive to enhanced atmospheric nitrogen (N) deposition. However, whether and how clonal plants with different growth forms differ in their responses to N deposition remains unclear. We investigated the long-term (14-year) and short-term (4-year) effects of N addition on clonal plants of three gro ...

Overgrazing can negatively affect plant performance, and consequently unbalance the association with AMF. We studied the grazing effect on AMF colonization for preferred (Bromus pictus and Poa ligularis) and unpreferred grasses (Pappostipa speciosa and Pappostipa humilis) by sheep in the Patagonia ...
