[rapd-pcr analysis of ground squirrels from the tobol-ishim interfluve: evidence for interspecific hybridization between ground squirrel species spermophilus major and s. erythrogenys].	populations of two ground squirrel species, spermophilus major and s. erythrogenys, from the interfluvial area of the tobol and ishim rivers, where their ranges overlap, have been examined using rapd-pcr. we have identified 253 loci, which included taxon-specific markers for s. major and s. erythrogenys as well as markers for geographic populations. estimation of genetic diversity and construction of phylogenetic relationships were performed using software programs popgene, tepga, and treecon. i ...	2005	16240632
[genetic evidence of extensive introgression of short-tailed ground squirrel genes in a hybridization zone of spermophilus major and s. erythrogenys, inferred from sequencing of the mtdna cytochrome b gene].	we have completely sequenced the mtdna cytochrome b gene of ground squirrels from the zone of overlapping ranges of spermophilus major and s. erythrogenys in the tobol-ishim interfluve, which is a putative hybridization zone of these species. the results of the sequencing showed extensive introgression of mtdna genes of the short-tailed ground squirrel s. e. brevicauda, whose haplotype had fully replaced the s. major haplotype. all of the ground squirrels from the tobol-ishim interfluve had a va ...	2006	16915930
[morpho-functional characteristics of reproductive organs of rodents from the area affected by a plant, processing gas with the increased content of sulfur compounds].	the biology of reproduction of 5 rodent species--small gopher (spermophilus pygmaeus pallas, 1778), reddish gopher (spermophilus major pallas, 1779), sasin lemmer (lagurus lagurus pallas,1773), forest mouse (apodemus sylvaticus linnaeus) and bank vole(clethrionomys glareolus schreber, 1780)--inhabiting the sanitary protective zone of the gas processing plant, was investigated with the use of histological, electron microscopical, immunocytochemical and morphometric methods. intensification of the ...	2008	19102254
[comparative morpho-functional characteristics of the organs of the reproductive system of small mammals under conditions of anthropogenic transformation of southern ural steppe ecosystems].	the morpho-functional characteristics of reproductive organs of small mammals--striped field mouse (apodemus agrarius pallas, 1771), house mouse (mus musculus linnaeus, 1758), wood mouse (sylvaemus uralensis pallas, 1811), common vole (microtus arvalis pallas, 1778), bank vole (clethrionomys glareolus schreber, 1780), steppe lemming (lagurus lagurus pallas, 1773), little suslik (spermophilus pygmaeus pallas, 1778), and red-heeked suslik (spermophilus major pallas, 1779)--belonging to the populat ...	2013	24592716
[biotope principles of sympatry and interspecies hybridization in mammals (by the example of the genus spermophilus)].	two hybridization zones were taken as an example (the russet ground squirrel (spermophilus major) and the speckled ground squirrel (spermophilus suslicus), the russet ground squirrel and the yellow ground squirrel (s. fulvus) to show that biotope characteristics determine segregation of sympatric species in contact populations. the heterogeneity of biotopes with regard to the requirements of sympatric species promotes their long-term and steady dispersal and, in rare cases, sporadic hybridizatio ...	2016	22567871
[breeding success and direction of animal crossing in the hybrid russet (spermophilus major) and yellow (spermophilus fulvus) ground squirrel population].	reproductive relations between animals in the hybrid settlement of the russet and yellow ground squirrels are panmictic and are characterized by the absence of assortative crossings and by the presence of multimale pairings in females with evidently heterospermic broods. maximum breeding success was observed for hybrid animals proving the fertility of hybrids. however, the hybrid breeding potential (young animal survival rate) is significantly lower as compared with russet and yellow ground squi ...	2016	22117418
