Siberia and Northwestern Russia are home to over 40 culturally and linguistically diverse indigenous ethnic groups, yet genetic variation and histories of peoples from this region are largely uncharacterized. We present deep whole-genome sequencing data (∼38×) from 28 individuals belonging to 14 distinct indigenous populations from that region. We combined these data sets with additional 32 mod...

Complete blood counts and blood chemistry in four Siberian husky puppies diagnosed with swimming puppy syndrome were compared with four healthy Siberian husky puppies. Only serum creatine kinase in affected puppies was significantly (P < 0.01) higher than in normal puppies. Although serum creatine kinase level cannot be used for diagnosis of this disease, it could serve as a tool for prognosis ...

The paper considers mechanisms for organizing free trade in the electricity market that are based on submitting bids of energy consumers and producers to the market operator. The authors discuss and compare possible strategies of generator behavior that lead to different equilibrium situations and correspond to Cournot model and the models of supply function equilibria, and a perfectly competit...

Transfer of adult Siberian hamsters, Phodopus sungorus, from long day (16 h light and 8 h dark; 16L:8D) to short day (8L:16D) photoperiods induces an involution of the gonads and a cessation of reproductive behavior 8-10 weeks later. The motoneurons of the spinal nucleus of the bulbocavernosus and their target muscles, the bulbocavernosus and the levator ani, are sexually dimorphic and are nece...

Siberian hamsters undergo torpor during the short days of winter and in response to glucoprivation or food restriction. We tested whether the area postrema and the adjacent nucleus of the solitary tract (hereafter the AP), which monitor metabolic fuel availability, also control the onset of torpor. Siberian hamsters that had manifested torpor spontaneously or had entered torpor in response to 2...

The mRNA expression of growth hormone (GH) gene in early development stages of Siberian sturgeon was investigated using RT-PCR method. Samples were collected from unfertilized eggs up to 50 days post hatched (dph) larvae in 11 different times. Ribosomal protein L6 (RPL6) transcripts were used as the internal standard during quantification of GH mRNA expression. The results showed that the GH mR...

[1] High interannual variability of summer surface salinity over the Laptev and East Siberian Sea shelves derived from historical records of the 1950s–2000s is attributed to atmospheric vorticity variations. In the cyclonic regime (positive vorticity) the eastward diversion of the Laptev Sea riverine water results in a negative salinity anomaly to the east of the Lena Delta and farther to the E...

Extra-pair paternity (EPP) in birds is related to a number of ecological and social factors. For example, it has been found to be positively related with breeding density, negatively with the amount of paternal care and especially high rates have been observed in group-living species. Siberian jays (Perisoreous infaustus) breed at low densities and have extended parental care, which leads to th...

Previous research has suggested that arctic populations have elevated metabolic rates in response to their cold, marginal climate. Recent studies of indigenous Siberian groups have confirmed these earlier findings and have shed light on the mechanisms through which northern populations adapt to their environments. Indigenous Siberians show significant elevations in basal metabolic rate compared...
