Genetic Analysis of Arctic Polar Bear Populations Using Historical Samples

This study analyzed genetic data using DNA isolated from museum specimens of polar bears in the collection of the Zoological Institute of the Russian Academy of Sciences. The unique data obtained in this study made it possible to characterize the population structure of polar bears in the past and to lay the foundation for further research. Methods of DNA isolation used in archaeogenetics and paleogenetics were applied to historical materials. These methods provided a sufficient quantity and quality of DNA suitable for high-throughput sequencing. The analysis of genetic variants made it possible to reveal the population structure of spatial and temporal polar bear populations in the Russian Arctic regions and its changes associated with the economic activities that unfolded in the first third of the 20th century.

期刊介绍： Biophysics is a multidisciplinary international peer reviewed journal that covers a wide scope of problems related to the main physical mechanisms of processes taking place at different organization levels in biosystems. It includes structure and dynamics of macromolecules, cells and tissues; the influence of environment; energy transformation and transfer; thermodynamics; biological motility; population dynamics and cell differentiation modeling; biomechanics and tissue rheology; nonlinear phenomena, mathematical and cybernetics modeling of complex systems; and computational biology. The journal publishes short communications devoted and review articles.
