Ineffective Management Causing Tropical Grassy Ecosystems To Be Threatened
2014-03-13 14:50:41

University of Liverpool Tropical grassy areas in India, Australia, and South America store around 15% of the world’s carbon Scientists at the University of Liverpool have found that tropical grassy areas, which play a critical role in the world’s ecology, are under threat as a result of ineffective management. According to research, published in Trends in Ecology and Evolution, they are often misclassified and this leads to degradation of the land which has a detrimental effect...

Savannah Ecosystems Threatened By Poaching
2014-02-12 20:00:11

Swedish Research Council White rhinoceros may be extinct in twenty years with the current poaching rates. The loss of this megaherbivore is in itself a tragedy, but it may also have tremendous effects on the ecosystems they now live in. The white rhino (Ceratotherium simum), and other megaherbivores, are key drivers of ecosystem functioning because they´re not controlled by predation. A new study by Joris Cromsigt and Mariska te Beest, published in Journal of Ecology, highlights the...

Predictions For Climate Change Effects On Savanna Vegetation Best Done By Continent
2014-01-31 08:05:48

North Carolina State University A "one-size-fits-all" model to predict the effects of climate change on savanna vegetation isn't as effective as examining individual savannas by continent, according to research published in Science this week. Savannas – grasslands dotted with trees – cover about 20 percent of the earth's land and play a critical role in storing atmospheric carbon, says Dr. William Hoffmann, associate professor of plant and microbial biology at North Carolina State...

Special Online-only  Issue Of Frontiers In Ecology And The Environment

ESA The Ecological Society of America’s first online-only Special Issue of Frontiers in Ecology and the Environment showcases prescribed burns around the globe, some of them drawing on historical practices to manage forests and grasslands in fire-prone regions. The Online Special Issue looks at fire practices in the United States, Australia, southern Europe, South Africa and South America. One review article focuses on the cooperative efforts of US ranchers in the Great Plains using...

Climate Science Boost With Tropical Aerosols Profile

CSIRO The seasonal influence of aerosols on Australia's tropical climate can now be included in climate models following completion of the first long-term study of fine smoke particles generated by burning of the savanna open woodland and grassland. Australia's biomass burning emissions comprise about eight per cent of the global total, ranking third by continent behind Africa (48 per cent) and South America (27 per cent). Lead researcher, CSIRO's Dr Ross Mitchell, said fine particles...

Deforestation in parts of Africa could be reversed with changes to land use, a study suggests. A more strategic approach to managing trees across the continent could have a positive impact on the changing climate, researchers say. A pioneering study of African savannas by the University of Edinburgh has revealed deforestation in south-central Africa, driven by rising populations in the aftermath of war, and increasing demand for trees for agriculture and fuel. This loss of forests...

April Flowers for redOrbit.com - Your Universe Online Scientists have debated how big a role elephants play in toppling trees in South African savannas for years. Now, using some very high tech airborne equipment, they finally have an answer. Tree loss is a natural process, but in some regions it is increasing beyond what could naturally be expected. This extreme tree loss has cascading effects on the habitats of many species. Studying savannas across Kruger National Park, Carnegie...

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 Cerrado (English: "inaccessible") is an immense tropical savanna ecoregion located in Brazil. It is distinguished by its wide variety of plant and animal biodiversity. According to the World Wildlife Fund, it is the richest savanna in the world, known for its flora and fauna. The climate of the Cerrado is mostly hot to semi-humid in the summer with a dry winter season which lasts from May to October. The annual precipitation for this region is between 31 - 63 inches. The soils are old,...
