Pastoral Livestock Farming in Southern Regions of Russia under Natural and Climatic Conditions of “Black Earth” of Kalmykia in 1930s.

Nauchnyi Dialog
The relevance of analyzing the historical experience of livestock development on migratory pastures in Southern Russia during the 1930s stems from the fact that agriculture is currently one of the most vital sectors of the country’s economy.

Post‐Soviet fire and grazing regimes govern the abundance of a key ecosystem engineer on the Eurasian steppe, the yellow ground squirrel Spermophilus fulvus

Diversity and Distributions, Volume 29, Issue 3, Page 395-408, March 2023., 2023
Abstract Aim Grazing intensity and fire patterns across the Eurasian steppes have changed dramatically over the past decades due to the collapse of the Soviet Union in 1991, and Kazakhstan is now a global fire hotspot. The implications of these changes for ecosystem functioning are largely unclear.

Impacts of Variations in Caspian Sea Surface Area on Catchment‐Scale and Large‐Scale Climate

Journal of Geophysical Research: Atmospheres, Volume 126, Issue 18, 27 September 2021., 2021
Abstract The Caspian Sea (CS) is the largest inland lake in the world. Large variations in sea level and surface area occurred in the past and are projected for the future. The potential impacts on regional and large‐scale hydroclimate are not well understood.

Measurements and Approximations for Submicron‐Aerosol Size Distribution Functions

Earth and Space Science, Volume 8, Issue 6, June 2021., 2021
Abstract Results of field measurements taken in the near‐Caspian (2002, 2003, 2007, 2009, 2010, 2011, 2013, 2014, 2016 years) and near‐Aral sea (1998) deserts under the conditions of weak winds (almost in the absence of saltation processes) and strong heating of the land surface are given. These results show that the fine mineral dust aerosol (0.1–1 m)

Post‐Soviet shifts in grazing and fire regimes changed the functional plant community composition on the Eurasian steppe

Global Change Biology, Volume 27, Issue 2, Page 388-401, January 2021., 2021
Post‐Soviet declines in livestock grazing on the Kazakh steppe corresponded to increases in grassland fires across large areas, causing the disturbance regime to shift from grazer to fire control. We show that grazing and fire each result in different plant functional compositions, which suggests widespread increases in grass cover and associated ...

Population and distribution of beavers Castor fiber and Castor canadensis in Eurasia

Mammal Review, Volume 51, Issue 1, Page 1-24, January 2021., 2021
A century ago, overhunting had reduced Eurasian beaver Castor fiber populations to c. 1200 animals in scattered refugia from France to Mongolia. Reintroductions and natural spread have since restored beavers to wide areas of their original range. The population has more than tripled since the first modern estimate in 1998, to c. 1.5 million.

EVALUATION OF HUMORAL AND CELLULAR IMMUNITY LEVEL AMONG PERSONS LIVING IN THE CASPIAN NATURAL SANDY FOCUS TERRITORY AFTER ANTI-PLAGUE REVACCINATION

Медицинская иммунология, 2018
In view of increasing epidemic danger potential of some natural plague foci and performing measures to provide specific prevention of this infection, it becomes necessary to carefully monitor the state of immunity in vaccinated (revaccinated) individuals.

Formation of spring barley yields in the arid part of the South of Russia

Зерновое хозяйство России, 2018
In the Russian Federation, barley occupy about 7.0 million hectares with an average yield of 12.0 hwt/ha. However, the main produc­tion of barley grain (52.0%) is located in the arid regions of the country, namely in the Southern and Privolzhsky ...
