چکیده
Spermophilus xanthoprymnus (Bennett, 1835), the Asia Minor ground squirrel, is a group-living, diurnal, obligately hibernating marmotine squirrel. It inhabits the steppes and alpine meadows throughout central lowland and eastern highland Anatolia and adjacent Armenia and northwestern Iran. Its preferred elevation appears to range from about 800 to 2,900 m. The species displays sexual dimorphism in size, with adult males being considerably larger than adult females and exhibits geographic variation in body size. It is presently listed as ‘‘Near Threatened’’ on the 2009 International Union for Conservation of Nature and Natural Resources Red List of Threatened Species because of large-scale agricultural activities that result in habitat destruction and fragmentation.

متن کاملMultiple paternity in Belding's ground squirrel litters.
Sexually receptive female Spermophilus beldingi (Rodentia: Sciuridae) usually mate with several different males. The paternity of 27 litters born in 1977 and 1978 was ascertained by combining field observations of mating with laboratory paternity exclusion analyses. Most of the litters (78 percent) were multiply sired, usually by two or three males. This may be the highest frequency of multiple...
متن کاملMultigenic and morphometric differentiation of ground squirrels (Spermophilus, Scuiridae, Rodentia) in Turkey, with a description of a new species.
This study reports on the molecular phylogenetics of ground squirrels, genus Spermophilus, in Turkey using cytochrome b (1140bp), part of the D-loop and flanking tRNAs (572bp), X chromosome (867-1051bp) and Y chromosome (983-989bp) DNA sequences. Individuals also were characterized by karyotype and with geometric morphometric analyses of mandibles and skulls. Two hundred fourteen individuals fr...
متن کاملA New Genus of Prairie Dog (Sciuridae, Rodentia) From the Miocene (Barstovian of Montana and Clarendonian of Nebraska) and the Classification of Nearctic Ground Squirrels (Marmotini)
A new genus of sciurid, Cynomyoides, is named. The new genus includes a new species from the late Clarendonian of Nebraska, C. vatis (type species), and an unnamed species from the early Barstovian of Montana. The dental and mandibular morphology of Cynomyoides is reminiscent of that of the latest Tertiary to Recent prairie dog Cynomys and is believed to be part of the lineage leading to Cynomy...
متن کاملImplications of Hybridization, NUMTs, and Overlooked Diversity for DNA Barcoding of Eurasian Ground Squirrels
The utility of DNA Barcoding for species identification and discovery has catalyzed a concerted effort to build the global reference library; however, many animal groups of economical or conservational importance remain poorly represented. This study aims to contribute DNA barcode records for all ground squirrel species (Xerinae, Sciuridae, Rodentia) inhabiting Eurasia and to test efficiency of...
