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)
The association between demographic history, genealogy and geographical distribution of mitochondrial DNA cytochrome b haplotypes was studied in the wood lemming (Myopus schisticolor), a species that is closely associated with the boreal forest of the Eurasian taiga zone from Scandinavia to the Pacific coast. Except for a major phylogeographic discontinuity(More)
BACKGROUND Like humans, the living elephants are unusual among mammals in being sparsely covered with hair. Relative to extant elephants, the extinct woolly mammoth, Mammuthus primigenius, had a dense hair cover and extremely long hair, which likely were adaptations to its subarctic habitat. The fibroblast growth factor 5 (FGF5) gene affects hair length in(More)
Climatic and environmental fluctuations as well as anthropogenic pressure have led to the extinction of much of Europe’s megafauna. The European bison or wisent (Bison bonasus), one of the last wild European large mammals, narrowly escaped extinction at the onset of the 20th century owing to hunting and habitat fragmentation. Little is known, however, about(More)
205 Hair of the woolly mammoth Mammuthus primigee nius Blumenbach, 1799 has been studied for many years. Judging from the ancient rock paintings, figuu rines, and preserved hair fragments, as well as from the data of numerous paleontological researches, the mammoth hair was long (up to 1 m or even longer), thick, multiitiered, and with topographical differr(More)
291 Skeletal remains and frozen corpses of fossil mamm mals, having special scientific value, are preserved in the permafrost. A considerable amount of such remains has been found in the Arctic zone of Yakutia, in regions of spreading ice sediments of the Yedoma suite. To date, more than 15 frozen corpses, including mammoths, wooly rhinoceroses, horses,(More)
The results of anatomical and morphological studies of new corpse remains of the fossil woolly rhinoceros found in 2007 in the lower reaches of the Kolyma River are described. These new data provide additional details of the specific features of the structures and sizes of individual body parts of the fossil rhinoceros and allow for several inferences on(More)
An analysis of the available data on the various adaptations of the woolly mammoth to the cryoarid conditions of the Ice Age is presented. Mammuthus primigenius had a set of specific anatomic–morphological (thick long three-row wool, small ears, a short tail, an adipose “hump”, a “hood”-like extension on the trunk, and wide soles of the feet) and(More)
Novel findings of fossil remains of the extinct artiodactyl Soergel’s ox, as well as some findings that were not analyzed previously, are presented in the article. Soergelia remains are extremely rare; therefore, the species range of these animals remains uncharacterized by now and the taxonomic positions of some findings are not clear. Analysis of the new(More)
Hair microstructure of the first calf of the woolly rhinoceros Coelodonta antiquitatis found in Sakha in 2014 (the neck and hind leg hair) was examined by the light and electron scanning microscopy. The calf hair features were compared with those of two adults studied earlier. The calf coat color was much lighter than in adults, from pale ashy to blond. The(More)
