The Intergovernmental Panel on Climate Change concluded that there is "discernible evidence" humans—through accelerating changes in multiple forcing factors—have begun to alter the earth's climate regime. Such conclusions are based primarily upon so-called "fingerprint" studies, namely warming pattern midtroposphere Southern Hemisphere, disproportionate rise nighttime and winter temperatures, statistical increase extreme weather events many nations. All three aspects of change variability...
Significance The frequency of the human-specific EDAR V370A isoform is highly elevated in North and East Asian populations. gene known to have several pleiotropic effects, among which are sweat gland density ductal branching mammary gland. former has led some geneticists argue that near-fixation this allele was caused by selection for modulation thermoregulatory sweating. We provide an alternative hypothesis, instead acted on allele’s effect increasing gland, thereby amplifying transfer...
Background A major challenge for ancient DNA (aDNA) studies on insect remains is that sampling procedures involve at least partial destruction of the specimens. recent extraction protocol reveals possibility obtaining from past without causing visual morphological damage. We test applicability this historic museum beetle specimens dating back to AD 1820 and chitin permafrost (permanently frozen soil) more than 47,000 years. Finally, we directly non-frozen sediments deposited 3280-1800 years...
A shrub tundra refugium on the Bering land bridge may have played a pivotal role in peopling of Americas.
Late Tertiary and early Quaternary fossil beds in the arctic regions of North America have yielded abundant, well-preserved remains plants arthropods, documenting existence coniferous forests high latitudes. Nearly all beetle (Coleoptera) specimens these assemblages represent extant species. We applied mutual climatic range (MCR) method paleotemperature analysis to from 11 sites estimate mean summer (T max ) winter min temperatures. found that T values during latest Miocene Pliocene were...
