The mitogenome of the Siberian flying squirrel is a circular molecule of 16,514 bp, consisting of a control region and a conserved set of 37 genes containing 13 protein-coding genes (PCGs), 22 tRNA genes, and 2 rRNA genes ( and ). The mitogenome of the Korean is AT-biased, with a nucleotide composition of 32.2% A, 30.4% T, 12.5% G, and 24.8% C. The phylogenetic analysis revealed that is well placed within the tribe Pteromyini (Sciuridae: Sciurinae), which forms a sister clade to the flying squirrels of the genus .

Understanding the diversity and causes of senescence patterns in the wild remains a challenging task, in particular among fast-living species for which senescence patterns have been poorly studied. Early life environmental conditions can shape senescence by influencing trade-offs between early and late life performance (disposable soma theory) or individual fitness through lifelong positive effects (silver spoon effects). Using a 23-year-long monitoring dataset of two populations of Siberian flying squirrels (Pteromys volans L.

Migratory shorebird populations are declining worldwide, showing an apparent inability to respond to the interplaying challenges emerging along their flyways. Within the East Atlantic Flyway, non-breeding populations show moderate to strong declines in Sub-Saharan Africa, contrasting with stable or increasing trends in Europe. Local factors are insufficient to explain the opposite tendencies and, therefore, investigating migratory strategies and connectivity of these populations may help identifying the drivers of their demography.

Amphibiotic insects, chironomids of the genera Glyptotendipes and Chironomus, which emerged from saline Lake Shira, differed in composition and content of fatty acids, including the essential eicosapentaenoic acid (20:5n-3, EPA), and upon flying out they were concentrated in different territories, the riparian zone and remote arid steppe zone, respectively. Potential consumers of chironomids adults, the orb-weaver spiders Larinoides suspicax, which inhabited both zones, also differed in fatty acid composition. The main difference in their biochemical composition was a significantly higher level of EPA in spiders from the riparian zone that likely to be explained by consumption of the Glyptotendipes adults enriched in this fatty acid and concentrated only within this zone.

Tick-Borne Encephalitis Virus (TBEV) is a dangerous arbovirus widely distributed in Northern Eurasia. The area of this pathogen changes over time. At the beginning of the 2000s, the Ixodes tick populations in Karelia increased.

It is much debated whether the direct effects of weather or biotic interactions determine species' responses to climate change. For example, an important biotic factor for herbivores in northern ecosystems is the availability of winter food. If the food availability changes because of the changing climate, it likely has major impact on the abundance of herbivores.
