From the kinds that people sneeze at, to the kinds that have prickly seeds that stick to pant legs, there are many different types of plants in grasslands around the world. According to a new analysis of plants in grassland ecosystems around the world, it turns out that most of those plant species are important. Brian Wilsey, associate professor, and Stanley Harpole, assistant professor, both in Iowa State University's Department of Ecology, Evolution and Organismal Biology, are authors...

Using sophisticated airborne imaging and structural analysis, scientists at the Carnegie Institution's Department of Global Ecology mapped more than 40,000 termite mounds over 192 square miles in the African savanna. They found that their size and distribution is linked to vegetation and landscape patterns associated with annual rainfall. The results reveal how the savanna terrain has evolved and show how termite mounds can be used to predict ecological shifts from climate change. The...

New study finds that the average ecosystem will need to shift about a quarter mile per year to keep pace with global climate change From beetles to barnacles, pikas to pine warblers, many species are already on the move in response to shifting climate regimes. But how fast will they - and their habitats - have to move to keep pace with global climate change over the next century? In a new study, a team of scientists including Dr. Healy Hamilton from the California Academy of Sciences have...

A group of scientists uncover the nitrogen dynamics of a common urban landscape. Areas of turf-forming species created and maintained by humans for aesthetic and recreational (not grazing) purposes, i.e. "urban grasslands" are an extremely common, but poorly studied ecosystem type. There are over 150,000 km2of urban grasslands in the U.S. and many receive high rates of fertilizer, creating concerns about nutrient runoff to streams, lakes, and estuaries and emissions of greenhouse gases such...

The wide-open spaces of the Flint Hills may no longer provide a secure home on the range for several familiar grassland birds, according to research by a Kansas State University ecologist and her colleagues. The researchers found that three bird species common to the Flint Hills region of Kansas and Oklahoma are experiencing serious population decline in the face of extensive land-management practices like annual burning and widespread grazing The Flint Hills contain the largest remaining...

Cattle and sheep grazed on natural grasslands help maintain biodiversity and produce tastier, healthier meat, according to a study funded by the Economic and Social Research Council (ESRC). The research, part of the Rural Economy and Land Use (RELU) program which draws together the social and natural science, concluded that pasture-based farming is good for the environment, the consumer and the producer but needs stronger support from British policy makers if it is to realize its full...

PAWHUSKA -- Two hundred years ago, bison herds of unfathomable immensity thundered across the tallgrass prairie as it stretched uninterrupted throughout central North America. The ecosystem that supported them has nearly disappeared. This month, a group of activists from Colombia visited one of the last vestiges of this landscape, in northern...

By Michelle Dynes Researchers have organized a project to get answers. By Michelle Dynes mdynes@wyomingnews.com CHEYENNE - Ten miles west of Cheyenne, carbon-dioxide levels are nearly twice as high as they are in the city. Well, at least in some test plots at the High Plains Grasslands Research Station. Thirty plots of native grasslands are part of an experiment to determine how local prairies could react to climate change. The results could shape congressional policy decisions,...

Dusky Pademelon, Thylogale brunii
2013-05-01 15:23:20

The dusky pademelon (Thylogale brunii), also known as the dusky wallaby, is a marsupial that can be found on the Kai and Aru islands, Papua New Guinea, and in the Trans Fly savanna and grasslands ecoregion in Papua Province in Indonesia. It prefers a habitat in both arid and tropical savannahs, forests, shrublands, lowlands, and grasslands. This species was named after its discoverer, Cornelis de Bruijn, and was once commonly known as philander, or “friend of man,” and the Aru Island...

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 forest-grasslands transition

The Central forest-grasslands transition are a prairie ecoregion of the central United States, a portion of the North American Great Plains. This is a great area that covers 157,000 square miles from central Illinois through the majority of Missouri, eastern Kansas, Oklahoma and into Texas. This region was conventionally a mixture of woodland and tall grass prairie, which as the soil is made up of highly fertile mollisols; most of the region has been transformed to farmland. The rainfall...

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...

Montana Valey And Foothill Grasslands
2013-04-19 14:34:54

The Montana Valley and Foothill grasslands are an ecoregion of northwestern North America within the northern United States and Canada. This area is made up of rolling grassy hills and river valleys of the Rocky Mountains foothills within the US state of Montana and the Canadian province of Alberta. The area largely consists of the Rocky Mountain Front, where the Great Plains rise to meet with the Rockies, and is therefore close to the Continental Divide. The foothills are drained by the...
