Two new docodontans, Simpsonodon sibiricus sp. nov. and Hutegotherium yaomingi gen. et sp. nov., and a new specimen of Itatodon tatarinovi Lopatin et Averianov, 2005 are described from the Middle Jurassic (Bathonian) Itat Formation of Krasnoyarsk Territory in West Siberia, Russia. A new phylogenetic analysis, incorporating 37 dental and mandibular characters and 18 docodontan and outgroup taxa ...

Species with a large geographic distributions present a challenge for phylogeographic studies due to logistic difficulties of obtaining adequate sampling. For instance, in most species with a Holarctic distribution, the majority of studies has concentrated on the European or North American part of the distribution, with the Eastern Palearctic region being notably understudied. Here, we study th...

BACKGROUND Since late 2003, the highly pathogenic influenza A H5N1 had initiated several outbreak waves that swept across the Eurasia and Africa continents. Getting prepared for reassortment or mutation of H5N1 viruses has become a global priority. Although the spreading mechanism of H5N1 has been studied from different perspectives, its main transmission agents and spread route problems remain...

Atmospheric components (aerosols and molecules) scatter and absorb solar radiation. They significantly influence the contrast and apparent resolution of satellite images of the Earth’s surface taken in the visible and near infrared spectral channels. For accurate interpretation of satellite signals, remote sensing data have to be corrected for atmospheric effects. This requires knowledge of atm...

Siberia is one of the coldest environments on Earth and has great seasonal temperature variation. Long-term settlement in northern Siberia undoubtedly required biological adaptation to severe cold stress, dramatic variation in photoperiod, and limited food resources. In addition, recent archeological studies show that humans first occupied Siberia at least 45,000 years ago; yet our understandin...

Recent outbreaks of highly pathogenic avian influenza (HPAI) have spread from SouthEast Asia to sixty-two Asian, Middle East, African and European countries. H5N1 viruses isolated from dead water birds in Mongolia and Hokkaido, Japan on the way back to their nesting areas in Siberia in April to May 2005, 2006, 2008, and 2009 were genetically closely related to those isolated from birds in China...

The Yakuts are a Turkic-speaking population from northeastern Siberia who are believed to have originated from ancient Turkic populations in South Siberia, based on archaeological and ethnohistorical evidence. In order to better understand Yakut origins, we modeled 25 demographic scenarios and tested by coalescent simulation whether any are consistent with the patterns of mtDNA diversity observ...

This paper describes a contextual classification approach to classify complex forest change classes. Multi temporal forest change classifications are performed comparing the 1989 baseline for the Kyoto definition of ARD (Afforestation, Reforestation and Deforestation) with the status in 2000 for test territories in Siberia with extensive ground truth information from forest inventory. The diffe...

Pachyseius anisimovi sp. nov. is described based on specimens from soil and litter in the Altai Mountains and the West and East Sayan Mountains in South Siberia, Russia. A key to ten Pachyseius species known from Asia is provided. 

We present a paleoparasitological analysis of the medieval Zeleniy Yar burial ground of the XII-XII centuries AD located in the northern part of Western Siberia. Parasite eggs, identified as eggs of Opisthorchis felineus, were found in the samples from the pelvic area of a one year old infant buried at the site. Presence of these eggs in the soil samples from the infant's abdomen suggests that ...
