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...

Shrubs Invade Remnant Hill Prairies
2014-03-11 16:18:39

University of Illinois Perched high on the bluffs of the big river valleys in the Midwest are some of the last remnants of never-farmed prairie grasslands. These patches, edged by forest, are slowly being taken over by shrubs. A recent University of Illinois study examined the soil microbes on nine patches, also called "balds," that had varying degrees of shrub invasion and found an interesting shift in the composition of the microbial community. "When we looked at the soil samples...

Grazing Animals May Protect Biodiversity In Over-Fertilized Grasslands
2014-03-11 09:34:12

April Flowers for redOrbit.com - Your Universe Online The Nutrient Network has released a new, comparative study of grasslands on six continents, to be published in an upcoming issue of Nature, that suggests it might be possible to counteract the human-made overdose of fertilizer that threatens to permanently alter the biodiversity of the world's native prairies. The key finding of this study, carried out at 40 sites globally, is simple: let grazing animals crop the excess growth of...

Butterfly Populations Might Be Saved By Land Management
2013-11-18 17:33:04

Lee Rannals for redOrbit.com – Your Universe Online Butterfly populations across the world are in the decline, and researchers say that land management could be the key to counteracting the pattern. Researchers from Sweden and Germany writing in the journal Nature Conservation reviewed effects of land management on butterfly diversity using historical and current surveys over the past 100 years. The study focused on systematic surveys of butterfly population trends and extinction...

Overgrazing Is Turning Parts Of Mongolian Steppe Into Desert
2013-09-06 13:27:48

Oregon State University 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. Using a new satellite-based vegetation monitoring system, researchers found that about 12 percent of the biomass has disappeared in this country that’s more than twice the size of Texas, and 70 percent of the grassland ecosystem is now...

Researchers Identify Unprotected Regions That Harbor The Majority Of Life On Earth
2013-09-05 16:23:48

American Association for the Advancement of Science Can the separate international commitments of protecting 17% of the planet's terrestrial surface and of conserving 60% of the world's plant species within these protected areas be met simultaneously by 2020? A new study suggests that they can—but only if researchers and conservationists do more to safeguard particularly hot spots of biodiversity. According to Lucas Joppa from Microsoft Research in Cambridge, England, and colleagues...

Grassland Butterfly Populations Sinking In Europe
2013-07-24 11:28:56

April Flowers for redOrbit.com - Your Universe Online A report from the European Environment Agency (EEA) reveals that between 1990 and 2011, grassland butterfly populations have declined dramatically, caused by intensifying agriculture and a failure to manage grassland ecosystems. According to the report, the drop in grassland butterfly numbers is particularly worrisome. These butterfly species are considered representative indicators of trends observed for a host of other land...

Human Influences Endangering Galapagos Sea Lions
2013-07-01 09:35:06

Brett Smith for redOrbit.com - Your Universe Online Like all biological functions, the immune system places demands on an organism and a new study in the journal PLoS ONE has found the highly active immune systems of some endangered Galapagos sea lions are stressing the animals to the point of starvation. In the study, the researchers compared two sea lion populations living within the archipelago: those near the human populated Islands of San Cristobal and those living by the...

Around half of Cambodia's tropical flooded grasslands have been lost in just 10 years according to new research from the University of East Anglia. The seasonally flooded grasslands around the Tonle Sap, Southeast Asia´s largest freshwater lake, are of great importance for biodiversity and a refuge for 11 globally-threatened bird species. They are also a vital fishing, grazing, and traditional rice farming resource for around 1.1 million people. Research published today in the...

The Great Basin shrub steppe ecoregion, located within the Deserts and xeric shrublands Biome, incorporates a variety of xeric shrub-steppe sub-ecoregions in the area of the Great Basin in the Western United States. It’s within the North American Desert area, and includes a great deal of Nevada, northeastern and eastern California east of the Sierra Nevada and Cascade Range rain shadows, and some parts of Utah and Idaho. The Great Basin Desert and semi-arid non-desert xeric shrubland...

Central tall grasslands
2013-04-19 18:16:33

The Central tall grasslands are a prairie ecoregion of the Midwestern United States, a portion of the North American Great Plains. It covers a large region of southern Minnesota, most of Iowa, and a small portion of eastern South Dakota and a narrow strip going through eastern Nebraska and northeastern Kansas. The rainfall here is 1,000 millimeters per year, which is higher than most of the Great Plains. The Northern tall grasslands are located to the north and have fewer and different...

Central and Southern mixed grasslands

The Central and Southern mixed grasslands are a prairie ecoregion of the central United States, a portion of the North American Great Plains. This is a vast grassland area with few trees running north to south from central Nebraska through central Kansas and western Oklahoma to north central Texas, covering about 282,000 square kilometers. This is a transition zone between the Central tall grasslands and Central forest-grasslands transition ecoregions towards the east and the Western short...
