Complex studies were carried out in the southern part of Onega Bay (White Sea) in the summer seasons of 2003–2006 and 2011–2013. These studies revealed the dynamics of oil pollution of the water area after an accidental fuel oil spill in September 2003 and its long-term adverse effects on organisms of different trophic levels of the coastal ecosystem (benthos, fish, and sea mammal populations) in the most polluted southeastern part of the bay. The deterioration of the status of the top trophic-level white whale population (a decrease in numbers) and the accumulation of oil hydrocarbons in tissues of benthic organisms are described. © 2016, Pleiades Publishing, Ltd.

The behavior of female polar bears with cubs in an isolated terrestrial area of Alexandra Land Island (Franz Josef Land Archipelago) was analyzed in the fall of 2011 in an ice-free period using Argos satellite telemetry and the data of ground observations. The size and structure of their home ranges and selection of their habitats have been estimated; the differences in behavior of tagged animals have been analyzed. © 2015, Pleiades Publishing, Inc.

The behavior of polar bear females with cubs on the isolated terrestrial area of Alexandra Land Island (the Franz-Josef Land Archipelago) was studied during the ice-free period in the autumn of 2011 using Argos sat- ellite telemetry and the data of ground observations. The animals' home range and habitat selection analyses were supplemented with the mutuality analysis. The personality was extracted for each specimen. Source

Identifying natural populations that might be considered separate units using morphology, genotype or both is important in understanding the process of speciation and for conservation. We examined the relationships between the only two subspecies of the most numerous Arctic seabird, the Little Auk Alle alle, using both morphological (wing and head-bill lengths) and genetic data (482 base pairs of the mitochondrial control region and seven nuclear microsatellite loci). We found significant morphological differences between the subspecies, A. a. polaris being significantly larger than the nominate A. a. alle. However, we did not find the subspecies to be differentiated at either mitochondrial DNA or at microsatellite loci. Consequently, one evolutionary significant unit is proposed. The similarity of the two subspecies at neutral genetic markers may be due to contemporary gene flow between populations, as well as large population sizes both in the present and in the past, combined with recent post-glacial colonization of the Artic. © 2015 British Ornithologists' Union.
