Yersinia pestis lineages in Mongolia. [PDF]

PLoS One, 2012
BACKGROUND: Whole genome sequencing allowed the development of a number of high resolution sequence based typing tools for Yersinia (Y.) pestis. The application of these methods on isolates from most known foci worldwide and in particular from China and ...

Dynamics of Epizootic Activity and Abundance of Mongolian Pika in the Altai Mountain Natural Plague Focus

Проблемы особо опасных инфекций, 2010
Long-term dynamics of epizootic activity (1961-2009) and the abundance (1980-2009) of Mongolian pika - the main agent carrier - was traced in Altai mountain plague natural focus. Cyclic fluctuations of Mongolian pika abundance with near eight-year period

Insight into microevolution of Yersinia pestis by clustered regularly interspaced short palindromic repeats. [PDF]

PLoS One, 2008
BACKGROUND: Yersinia pestis, the pathogen of plague, has greatly influenced human history on a global scale. Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR), an element participating in immunity against phages' invasion, is composed of ...

Genotyping and phylogenetic analysis of Yersinia pestis by MLVA: insights into the worldwide expansion of Central Asia plague foci. [PDF]

PLoS One, 2009
BACKGROUND: The species Yersinia pestis is commonly divided into three classical biovars, Antiqua, Medievalis, and Orientalis, belonging to subspecies pestis pathogenic for human and the (atypical) non-human pathogenic biovar Microtus (alias Pestoides ...

Contribution of cultural heritage values to steppe conservation on ancient burial mounds of Eurasia

Conservation Biology, Volume 37, Issue 6, December 2023., 2023
Abstract Civilizations, including ancient ones, have shaped global ecosystems in many ways through coevolution of landscapes and humans. However, the cultural legacies of ancient and lost civilizations are rarely considered in the conservation of the Eurasian steppe biome.

The role of refuges in biological invasions: A systematic review

Global Ecology and Biogeography, Volume 32, Issue 8, Page 1244-1271, August 2023., 2023
Abstract Aim Ecological refuges buffer organisms against stressors and mediate a range of species interactions. However, their role in the context of biological invasions has yet to be synthesized, despite the increasing prevalence and impact of non‐native species.

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.

Spatio‐temporal occurrence and sensitivity to livestock husbandry of Pallas's cat in the Mongolian Altai

The Journal of Wildlife Management, Volume 86, Issue 1, January 2022., 2022
Pallas's cat occupancy increases with increasing livestock occurrence, particularly large herds of sheep and goats. Such spatial convergence is partially adjusted by diel activity segregation, presumably to limit direct encounters. The cat's dependence on areas that are increasingly used for grazing is of great conservation concern, since this may ...
