Scientists speaking at the annual meeting of the American Geophysical Union in San Francisco say the formation of the Hangay and the Altai mountain ranges may have led to the expansion of Asia’s largest desert.
Overgrazing by millions of sheep and goats is the primary cause of degraded land in the Mongolian Steppe, one of the largest remaining grassland ecosystems in the world, Oregon State University researchers say in a new report.
This Envisat image shows part of central Morocco from the Atlantic Ocean to the west, over the Atlas mountains and into arid parts of Algeria further inland.
The Bechstein’s bat or Myotis bechsteinii lives in deciduous forests. It used to be very common in the Holocene era, but today there are only a few dispersed groups, despite the fact that a colony can be found almost anywhere in Europe.
A NASA-led team has used radar sounding technology developed to explore the subsurface of Mars to create high-resolution maps of freshwater aquifers buried deep beneath an Earth desert, in the first use of airborne sounding radar for aquifer mapping.
In a new study, researchers have found what they believe to be a new pathway that allowed modern humans to spread beyond their ancestral homeland about 120,000 years ago.
On an almost daily basis, Jeff Peterson, MD, would be informed that there were "beaucoup de malades nomads" --many sick people--who had come by camel in search of medical assistance. Most of them had never received any medical care before.
New North African climate reconstructions reveal three â€˜green Saharaâ€™ episodes during which the present-day Sahara Desert was almost completely covered with extensive grasslands, lakes and ponds over the course of the last 120.000 years.
Sahara Energy, engaged in oil and gas exploration and development, has sold its 30% operated working interest in one gas well located at Gold Creek, Alberta, for proceeds of approximately C$180,035. Proceeds from the sale will be used to pay down Sahara's existing bank debt.
A recent study on the future of climate changes suggests that the once-green Sahara turned to desert over thousands of years rather than in an abrupt shift as previously believed.
The Kazakh Steppe, alternatively called Kirghiz Steppe, ecoregion located in the Palearctic Temperate grasslands, savannas, and shrublands Biome, is a wide region of open grassland in the northern part of Kazakhstan and adjacent portions of Russia, stretching eastwards to the Pontic steppe and to the west of the Emin Valley steppe, with which it creates part of the Eurasian steppe. The steppe stretches out more than 2,200 kilometers from the area east of the Caspian Depression and north of...
The Kazakh Uplands, known also as the Kazakh Hummocks, is a large peneplain formation that stretches throughout the central and eastern regions of Kazakhstan. It’s made up of low mountain oases and elevated plains, and contains large deposits of coal within the north and copper within the south. Rare species, such as the Asiatic Cheetah, may still reside in this region. Several notable cities, including the country’s capital, Astana, are located there. A portion of the Kazakh Uplands...
The Mongolian-Manchurian grassland ecoregion, known also as the Mongolian-Manchurian Steppe, located in the temperate grassland Biome, is found in Mongolia, the Chinese Autonomous region of Inner Mongolia and northeastern China. The grassland covers an area of 342,600 square miles. This Palearctic temperate grasslands, savannas, and shrublands ecoregion of the Temperate grasslands, savannas, and shrublands Biome, creates a large crescent around the Gobi Desert, stretching across central...
The Pontic-Caspian Steppe is the massive steppeland that stretches from the northern shores of the Black Sea as far east as the Caspian Sea, from western Ukraine across the Southern Federal District and the Volga Federal District of Russia to western Kazakhstan, creating part of the larger Eurasian steppe, adjacent to the Kazakh steppe towards the east. It’s a portion of the Palearctic temperate grasslands, savannas, and shrublands ecoregion of the temperate grasslands, savannas, and...
As the world’s second-largest and second most populous continent, Africa is about 11.7 sq. miles including adjacent islands. It covers 6 percent of the Earth’s total surface area and 20.4 percent of the total land area. With 1 billion people, it accounts for about 15 percent of the world’s human population. It is surrounded by the Mediterranean Sea to the north, both the Suez Canal and the Red Sea along the Sinai Peninsula to the northeast, the Atlantic Ocean to the west, and the Indian...
