Stable isotopes and soil-geomorphology as indicators of Holocene climate change, northern Chihuahuan Desert
Coeval !!"C shifts recorded in buried soils at both piedmont slope and basin floor sites in the northern Chihuahuan Desert indicate a major shift from C # grasses to C " desert-scrub between 7 and 9 ka. The age assignments are based on stratigraphic correlations to charcoal dates and carbon-14 dates of carbonate. This shift is synchronous with a period of cooling in the North Atlantic that may ...

متن کاملAdaptation of redband trout in desert and montane environments.
Natural populations that evolve under extreme climates are likely to diverge because of selection in local environments. To explore whether local adaptation has occurred in redband trout (Oncorhynchus mykiss gairdneri) occupying differing climate regimes, we used a limited genome scan approach to test for candidate markers under selection in populations occurring in desert and montane streams. ...
متن کاملGeomorphology of Uluru, Australia
A famous and well known Australian inselberg,1 Uluru,2 is an interesting geological feature in that its geomorphology is still a matter of controversy among conventional geologists. Traditionally, Uluru’s stratigraphical history began hundreds of millions of years ago, being fashioned into its current contour only as recently as between 60 million years ago until the present. The process by whi...
متن کاملThe geomorphology of Ceres.
Analysis of Dawn spacecraft Framing Camera image data allows evaluation of the topography and geomorphology of features on the surface of Ceres. The dwarf planet is dominated by numerous craters, but other features are also common. Linear structures include both those associated with impact craters and those that do not appear to have any correlation to an impact event. Abundant lobate flows ar...
