7 [1] We analyse the evolution of the fraction of water 8 surface (FWS), derived by SSM/I between 1988 and 2002 9 over the Western Siberia Lowland. This whole region 10 exhibits an increase in the amount of FWS that is in 11 agreement with the observed trends of the Ob river 12 discharge and precipitation. However, a similar increasing 13 trend is not found over the most important wetland area ...
IL-18 has proinflammatory effects and participates in both innate and adaptive cellular and humoral immunity. A number of SNPs that influence IL-18 production are found in the gene promoter region. We investigated the association of SNPs in the IL-18 promoter at -607 and -137 with the level of IL-18 protein production by PBMC from healthy donors from Southwestern Siberia. The genetic distributi...
Before migrating into North America, early humans first moved into Arctic Siberia and adapted to its harsh environment. The few oldest sites have been dated to at most about 15,000 years ago or so, which was after the major Northern Hemisphere ice sheets had begun to recede. Pitulko et al. (p. 52; see the cover and the news story by Stone) now report a series of radiocarbon ages and artifacts f...
Genetic variation at seven microsatellite DNA loci was quantified in 19 herds of wild caribou and domestic reindeer (Rangifer tarandus) from North America, Scandinavia and Russia. There is an average of 2.0-6.6 alleles per locus and observed individual heterozygosity of 0.33-0.50 in most herds. A herd on Svalbard Island, Scandinavia, is an exception, with relatively few alleles and low heterozy...
* Corresponding author. Abstract – In this paper results of an object oriented image analysis approach for forest change detection based on spectral, contextual and object specific attributes are presented. A change detection classification system is developed that derives a change map using 1989 and the status in 2000 for selected forest inventory test territories in Siberia with extensive gro...
Apodemus peninsulae is a field mouse that inhabits the broad-leafed forests of temperate Eurasia. We examined the mitochondrial cytochrome b gene in 57 individuals of A. peninsulae from northeastern Asia, including Siberia, Primorye, Magadan region, Sakhalin, Hokkaido, and the Korean Peninsula. The genealogy of the mitochondrial DNA (mtDNA) in A. peninsulae was shown to have substantial geograp...
Purpose: Settlements in Southern Siberia, identification of nodal points urban development with respect to geological landscape conditions; the relationship between structure and settlement system location town-forming centers; ways transformation. Methodology: River basin planning, which offers zoning territory accordance river basins as well landscape-ecological approach spatial transformatio...
African swine fever (ASF) is arguably the most dangerous and emerging swine disease worldwide. ASF is a serious problem for the swine industry. The first case of ASF in Russia was reported in 2007. We report an outbreak of ASF in Siberia, Russia, in 2017.
Methylovulum psychrotolerans Sph1T is an aerobic, obligate methanotroph, which was isolated from cold methane seeps in West Siberia. This bacterium possesses only a particulate methane monooxygenase and is widely distributed in low-temperature environments. Strain Sph1T has the genomic potential for biosynthesis of hopanoids required for the maintenance of intracytoplasmic membranes.
