| Summary: | 101. Narrow-headed Vole Lasiopodomys gregalis French: Campagnol gréle / German: Schmalkopf-Wiihimaus / Spanish: Topillo de cabeza estrecha Other common names: Narrow-skulled Vole Taxonomy. Mus gregalis Pallas, 1779, E of Chulym River, Novosibirsk Region, Russia. Lasiopodomys gregalis is in subgenus Stenocranius. Morphologically and genetically, it is a sister species to L. raddei. In the past, it was placed in the genus Microtus. Within L. gregalis, there are three distinct mtDNA clades, north-western (northern, western, and central Siberia, Altai, and Tian Shan), central (Tuva), and south-eastern (south of eastern Siberia and northern Mongolia). The first clade is subdivided into six geographically distinct lineages: steppes of western Siberia, Yamal Peninsula and Northern Ural Mountains, northern Altai Mountains, southern Altai Mountains, Yakutia (= Sakha Republic), and Tian Shan. Phylogeographic structure reflects complex history of L. gregalis that includes a Middle Pleistocene dispersal from Altai region toward the north and south-west, followed by a wide distribution across tundra-steppe landscapes during most of the Pleistocene, and finally decrease and fragmentation of the distribution due to humidification of climate and a wide advance of tree vegetation at the Pleistocene— Holocene boundary. Geographical variation is expressed as a complex combination of clines and mosaic variability in size, color, and skull proportions. Eighteen forms of subspecific rank have been described, but they weakly reflect existing patterns of morphological and genetic variation. Subspecific taxonomy requires reassessment. Distribution. Subdivided into several isolated patches of different size: N sections located along Arctic shore in Russia from Northern Dvina River E to Kolyma River (Arkhangelsk Region, Nenets Autonomous District, SE Novaya Zemlya, Vaygach I, Northern Ural Mts, Yamal Peninsula, Belyy I, S Taymyr Peninsula, and N Yakutia), C section includes C Yakutia, and S sections extend from Kama River E to Amur River ... |
