متن کاملPhylogeography of the Y-chromosome haplogroup C in northern Eurasia.
To reconstruct the phylogenetic structure of Y-chromosome haplogroup (hg) C in populations of northern Eurasia, we have analyzed the diversity of microsatellite (STR) loci in a total sample of 413 males from 18 ethnic groups of Siberia, Eastern Asia and Eastern Europe. Analysis of SNP markers revealed that all Y-chromosomes studied belong to hg C3 and its subhaplogroups C3c and C3d, although so...
متن کاملProbabilistic projections of 21st century climate change over Northern Eurasia
We present probabilistic projections of 21st century climate change over Northern Eurasia using the Massachusetts Institute of Technology (MIT) Integrated Global System Model (IGSM), an integrated assessment model that couples an Earth system model of intermediate complexity with a two-dimensional zonal-mean atmosphere to a human activity model. Regional climate change is obtained by two downsc...
متن کاملThe State of Silurian
The geological sciences demand close international cooperation as wel as a rigorous and clearly understood language of words. Nowhere is this more keenly felt than in stratigraphy where, despite the luxury of long philosophical discussions on rocks versus time, many feel a sense of urgency about attempts to achieve a standard global chronostratigraphy. The now wel-known pioneer work of the inte...
متن کاملRelationships of Lower Silurian Strata in Ohio, West Virginia, and Northern Kentucky
The Brassfield Formation, consisting mainly of carbonate strata, is overlain by beds of the Dayton Formation at several localities in southwestern Ohio, high on the east flank of the Cincinnati Arch. The Brassfield thickens eastward into the subsurface and becomes separated from the Dayton by an expanding wedge of shale and carbonate beds. The writer considers these beds to be equivalent to the...
