Autor: Arkady B. Savinetsky, G. G. Boeskorov, Olga A. Krylovich, M. V. Shchelchkova

Publikováno v: Biology Bulletin. 47:1013-1021

To assess the trophic position of the exceptionally large-sized brown bears from the Pleistocene of Yakutia, we used stable nitrogen and carbon isotope analyses of the collagen contained in fossil bones and teeth. Modern brown bears of Yakutia were c

Adaptation of the woolly mammoth Mammuthus primigenius (Blumenbach, 1799) to habitat conditions in the glacial period

Autor: E. N. Mashchenko, V. V. Plotnikov, N. G. Solomonov, A. V. Protopopov, G. G. Boeskorov, M. V. Shchelchkova

Publikováno v: Contemporary Problems of Ecology. 9:544-553

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

Thermodynamic indices of active invertase from the buried soil horizons of Late Pleistocene age in northern Yakutia

Autor: M. V. Shchelchkova

Publikováno v: Contemporary Problems of Ecology. 2:109-113

New data on the enzymatic activity of the tundra peaty gleyey soil and permafrost sediments of Late Pleistocene age (11–25 thousand years) are analyzed. It is shown that invertase, protease, phosphatase, catalase, and peroxidase are well conserved
