The intrapopulation variability of a cytochrome b gene fragment and the corresponding amino acid sequence was studied in the red vole Clethrionomys rutilus Pallas, 1779 from the flood-plain of the Kolyma River. Wide polymorphic variability of these properties was observed. Differences in the cytochrome b gene sequence were determined between the re...

This study examines discrete features in the northern fur seal Callorhinus ursinus related to the shape of the posterior edge of the front flipper, which is characterized by a varying degree of manifestation of quantitative (number of festoons) and qualitative (shape, size, and arrangement of lobes) features of each digit. Analysis of frequencies o...

The data on allozyme variability of some genetic biochemical markers of field mouse, that is a recent newcomer in the territory of Magadan Region, are compared with those of probable donors from other areas. A significant genetic variability is reported for studied samplings in the majority of analyzed loci. Since any significant loss in genetic va...
Article
A method for detecting activities of mannose- and glucose-6-phosphate isomerases based on enzyme production of the substrates is described. The results obtained for several animal taxa are illustrated by photographs.

... Although limited material from islands of the Peter the Great Bay (4 from Putyatin Island; 2, from Askold; 5, from Reyneke; 5, from Russky) was included in the phylogeographic study of Apodemus species in Asia based on the mtDNA cyt b gene (Sakka et al., 2010), differentiation of island populations of the striped field mouse was not specially considered in this work. In other studies, variability of nuclear genes (Atopkin et al., 2007;Zasypkin et al., 2007;Dokuchaev et al., 2008) and mitochondrial (Pereverzeva and Pavlenko, 2014) genes was analyzed in mice from mainland populations of the Far East of Russia. ...
... The data on the number of newborn pups at the rookery in 1958-2013, as well as the data on the age structure and physiological condition of females taken at sea for research purposes (hereinafter referred to as marine samples) in , were also used. The material was collected by the staff of the Pacific Research Fisheries Center (TINRO Center) in various years [5][6][7][8][9]. ...
