A large and highly dynamic aquatic system called Paratethys governed important elements of the middle late Miocene (15.97–5.33 Ma) hydrology in western Eurasia. So far, impact vast water body on Eurasian climate, however, is not yet understood. Here we apply biomarker analyses coupled to compound-specific hydrogen carbon isotope data track changes sea surface temperature, mean annual air hydrol...
The occurrence of Francisella tularensis outside of endemic areas, such as North America and Eurasia, has been enigmatic. We report the metagenomic discovery and isolation of F. tularensis ssp. holarctica biovar japonica from diseased ringtail possums in Sydney, Australia. This finding confirms the presence of F. tularensis in the Southern Hemisphere.
The Out-of-Africa-Theory, as a model of the early migration of anatomically modern humans, describes Africa as geographical source of dispersal processes to Eurasia. However, there is no scientific consensus on the reason or the exact route of the migration. In this paper key challenges for modeling hominin biogeography and expansion using agent-based approaches are being proposed.
Gamasiphis angaridis sp. n. is described from females and males collected from litter and soil in the North Asian part of Russia-Siberia and the Far East. This is the first species of the large genus Gamasiphis to be described from the northern Palaearctic Region. A key for the separation of females of the 11 recognisable species of Gamasiphis described in Eurasia is provided.
Both seasonal and pandemic influenza continue to challenge both scientists and clinicians. Drug-resistant H1N1 influenza viruses have dominated the 2009 flu season, and the H5N1 avian influenza virus continues to kill both people and poultry in Eurasia. Here, we discuss the pathogenesis and transmissibility of influenza viruses and we emphasize the need to find better predictors of both seasona...
The U.S. lineage, one of the major clades in the Babesia microti group, is known as a causal agent of human babesiosis mostly in the northeastern and upper midwestern United States. This lineage, however, also is distributed throughout the temperate zone of Eurasia with several reported human cases, although convincing evidence of the identity of the specific vector(s) in this area is lacking. ...
We examine the problem of partitioning between shortening and extrusion in the India-Asia collision since 45 Ma. We compute the amount of shortening expected from the kinematics of India's motion with respect to Eurasia, using the reconstruction at collision time to put bounds on the possible amounts of surface loss within Greater India and within Eurasia. We then compute the amounts of surface...
