In the arid Mojave Desert, small burrowing mammals such as the cactus mouse, the kangaroo rat and the white-tailed antelope squirrel are weathering the hotter, drier conditions triggered by climate ch...
Death Valley doesn't seem like the best place to ride out rising temperatures amid a changing climate. But for the desert plants that live there, it's home -- and they face the choice to adapt or die....
Deserts of the U.S. Southwest are hot and dry -- extreme habitats for most plants -- but, remarkably, microscopic green algae that live there are extraordinarily tolerant of dehydration.These tiny gre...
As temperatures rise, desert birds need more water to cool off. At the same time, deserts are becoming drier, setting some species up for a severe crash, if not extinction, according to a new study pu...
An ancient desert covered in sand dunes as far as the eye could see, where dinosaurs and small mammals once roamed, may have been the real Jurassic Park. Today, the Navajo Sandstone, as it's called, i...
An abnormal season of intense glacial melt in 2002 triggered multiple distinct changes in the physical and biological characteristics of Antarctica’s McMurdo Dry Valleys over the ensuing decade, new r...
According to NASA, 2016 was the hottest year on historical record. Globally, the increase amounted to nearly 1.8 degrees Fahrenheit. And while that might not sound like much of an increase, it could m...
Each spring, powerful dust storms in the deserts of Mongolia and northern China send thick clouds of particles into the atmosphere. Eastward winds sweep these particles as far as the Pacific, where du...
The combined effects of drought, warming and the changes in land cover have caused severe land degradation for several decades in the extremely arid desert oases of southern Xinjiang, northwest China....
Strain distribution across broad plate boundaries is inadequately understood. California's Mojave Desert has been adjacent to Tertiary convergent and transform plate margins and its general geology is...
Seven distinctly different museum-quality concretionary morphotypes of elongate, spheroidal, banded, botryoidal, columnar, rosette, and speleothem in regolith at two small sites at the base of the Mes...
RIVERSIDE, Calif. — Using ancient DNA analysis and other techniques, a research team led by conservation biologists at the University of California, Riverside has determined that bighorn sheep, so nam...
For proper water management in the new reclaimed areas, hydraulic parameters of both aquifer and wells related to transmissivity, specific capacity, well loss, formation loss, and water entrance veloc...
Mounting discoveries of extrasolar planets orbiting post-main sequence stars motivate studies aimed at understanding the fate of these planets. In the traditional "adiabatic" approximation, a secondar...
An arid land, known as the Syrian Desert, is covering a large part of the Middle East. In the past,this harsh environment, characterized by huge lava fields, the “harraat”, was considered as a barrier...
