Necessity of organization of a cryobank for the sperm of some taxa has been substantiated on the basis of the published data and authors' results concerning the state of genetic resources of the family Cervidae in Russia. A task has also been set to elucidate some factors that may affect the success of cryoconservation, such as the age of male donors;(More)
Habitat loss threatens large mammals worldwide, and their survival will depend on habitat in human-dominated landscapes. Conservation planners thus face the challenge to identify areas of least conflict with land use, yet broadscale species distribution models rarely incorporate real landscape patterns nor do they identify potential conservation conflicts.(More)
Despite decades of research, the roles of climate and humans in driving the dramatic extinctions of large-bodied mammals during the Late Quaternary period remain contentious. Here we use ancient DNA, species distribution models and the human fossil record to elucidate how climate and humans shaped the demographic history of woolly rhinoceros, woolly(More)
Polymorphism of kappa-casein gene (alleles A and B) in Belovezhsky and Caucasian-Belovezhsky European bisons, bisons and their hybrids, as well as in cattle, yaks, and Yakut cattle was studied by PCR method, followed by restriction analysis. European bisons and yaks, being referred, correspondingly, to genera Bison and Bos of Bovidae family, were stated to(More)
The data on 16 polymorphic systems (22 loci) of blood biochemical markers were studied in different breeding lines of European bison: Lowland, Lowland-Caucasian, and Mountain lines. Polymorphism was revealed in three loci: Pgm, Idh, and Tf. The average heterozygosity was 3.95%. Statistically significant deviation from the Hardy-Weinberg equilibrium towards(More)
Analysis the of cytochrome b gene (1140 b.p.) polymorphism and polymorphism of 79 specimens of the control region (934 b.p.) of mtDNA of the Siberian roe deer Capreolus pygargus from 23 regions of Russia and Kazakhstan has been carried out. The combined alignment of two fragments of mitochondrial DNA revealed 36 haplotypes, which are distributed in three(More)
Polymorphism of nine blood group systems was studied in three reproductive lines of auroch (European bison Bison bonasus), Belovezhskaya, Caucasian-Belovezhskaya, and Gornaya. All blood group systems analyzed were polymorphic; 50 out of the 57 antigens tested were detected. The number of detected blood group antigens in aurochs is comparable to that in(More)
The extinction of large northern herbivores is a puzzle for many biologists. Is it caused by climate change or human activity? The survival of the weak trophic competitors promotes the “anthropogenic” hypothesis. The extant species of Pleistocene communities allow us to easily test this assumption. The reindeer and musk ox have been until now coexisting in(More)
The muskoxen populations introduced to the Taimyr Peninsula and Wrangel Island in 1974 to 1975 were examined for sequence variation at seven microsatellite loci. Donor material originated from the populations of Banks Island (Canada) and Eastern Greenland. Relative to the allele frequencies, both introduced populations demonstrated rather strong deviation(More)
