Recent changes in climate, disturbance regimes and land use and management systems in Northern Eurasia have the potential to disrupt the terrestrial sink of atmospheric CO2 in a way that accelerates global climate change. To determine the recent trends in the carbon balance of the arctic and boreal ecosystems of this region, we performed a retrospective analysis of terrestrial carbon dynamics a...

Recent introduction of H5N1 highly pathogenic avian influenza virus (HPAIV) in wild birds from poultry in Eurasia signaled the possibility that this virus may perpetuate in nature. Surveillance of avian influenza especially in migratory birds, therefore, has been conducted to provide information on the viruses brought by them to Hokkaido, Japan, from their nesting lakes in Siberia in autumn. Du...

The Middle to Upper Paleolithic boundary marks an important threshold in human cultural and biological evolutionwith the establishment of Anatomically Modern Humans and the termination of Neandertal settlement in Eurasia between 40–30 ka C BP. The demographic and cultural processes underlying this ‘‘transition’’ throughout Eurasia are among the most intensively debated issues in Paleolithic Arc...

The role of wild birds in the epidemiology of the Asian lineage highly pathogenic avian influenza (HPAI) virus subtype H5N1 epizootic and their contribution to the spread of the responsible viruses in Eurasia and Africa are unclear. To better understand the potential role of swans and geese in the epidemiology of this virus, we infected 4 species of swans and 2 species of geese with an HPAI vir...

In recent years, the influence of Muslims and Islam on developments in medieval Europe has captured attention scholars general public alike. Nevertheless, ‘conversion’ to remains a challenging subject for historical research demands more transdisciplinary collaborations. This article examines early interactions between Muslim Arabs Northern Eastern Europeans as case study whether some individua...

Broomcorn millet (Panicum miliaceum) was known throughout Eurasia in the second millennium BC in regions with warm, moist summers, where its cultivation reduced agricultural risk. Its cultivation during the warm, but dry months at Kyzyltepa and other Iron Age sites in western Central Asia was probably made possible through irrigation practices that were long known and originally developed in th...

Tectonic interpretations of arc remnants in the Himalayan orogen remain uncertain, despite their important implications for overall convergence history between India and Eurasia. Provenance results from deep-water volcaniclastic rocks Indus Suture Zone Ladakh provide new constraints on Mesozoic tectonic evolution Dras Kohistan-Ladakh arcs. Detrital zircon (DZ) U-Pb ages whole-rock geochemistry ...
