Global Warming Smaller Bison
2013-06-21 08:39:15

Brett Smith for redOrbit.com - Your Universe Online As climate changes and global temperatures increase, the average size of the iconic American bison will decrease, according to a new study in the journal PLOS ONE. "Bison are one of our most important conservation animals and hold a unique role in grasslands in North America," said study author Joseph Craine, a biology professor at Kansas State University. "In addition to their cultural and ecological significance, they're economically...

Volcanic Grit Played Key Role In Strong Tooth Development
2013-03-05 19:55:56

Brett Smith for redOrbit.com — Your Universe Online Archeologists have long assumed the evolutionary development of strong, thick-enameled teeth coincides with a mammals shift to a diet of field grasses. However, a new study in Nature Communications shows some Argentine mammals developed sturdy chompers in response to gritty volcanic dust that appeared in their tropical rainforest habitat. “The assumption about grasslands and the evolution of these teeth was based on...

Plant Biodiversity Protects Ecosystems From Human Perils
2013-02-07 08:59:14

April Flowers for redOrbit.com - Your Universe Online A new study led by integrative biologists at the University of Guelph warns of the perils inherent in an ecosystem breakdown. The findings of the study, which appeared as the cover story in today´s issue of the journal Nature, suggest that resource managers and farmers should not rely on single crop monocultures, no matter how stable they may appear to be. The team suggests instead that farmers should cultivate the growth of more...

Diversity Helps To Maintain Grasslands During Drought
2012-08-09 10:21:11

Brett Smith for redOrbit.com - Your Universe Online As drought ravages grasslands across the United States, a few American scientists are looking into how different species of grass endure these harsh conditions. In a study that could impact everything from the beef industry to lawn care, a University of Kansas-led team examined the resilience of 426 species of grass from around the world and found that diversity is key in maintaining robust grasslands, according to their report...

Fossilized Teeth Point To World’s Oldest Grasslands In Chilean Andes
2012-07-25 05:14:14

Brett Smith for redOrbit.com - Your Universe Online Two newly discovered and ancient rodent species, including the earliest known chinchilla, may have lived in the world´s oldest grasslands about 32.5 million years ago. The discovery and subsequent analysis of the teeth by an international team of researchers, which was published in the journal American Museum Novitates, supports previously collected evidence indicating that these animals once inhabited an open and dry environment...

Development Of Grassroots Approach To Conservation
2012-07-11 11:20:38

A new strategy to manage invasive species and achieve broader conservation goals is being tested in the Grand River Grasslands, an area within the North American tallgrass prairie ecoregion. A University of Illinois researcher along with his colleagues at Iowa State and Oklahoma State Universities enlisted private landowners in a grassroots community-building effort to establish a more diverse landscape for native wildlife. The Grand River Grasslands has three main problems that pose...

Mesquite Trees Displacing Southwestern Grasslands
2012-03-19 04:15:21

As the desert Southwest becomes hotter and drier, semi-arid grasslands are slowly being replaced by a landscape dominated by mesquite trees, such as Prosopis velutina, and other woody shrubs, a team of University of Arizona researchers has found. In a "leaf-to-landscape" approach, the team combined physiological experiments on individual plants and measurements across entire ecosystems to quantify how well grasslands, compared to mesquite trees and woody shrubs, cope with heat and water...

The city of Manila holds the human world record for the most densely populated space and now an international team of ecologists are seeking the natural equivalent, the most species rich area on earth. The team's findings, published in the Journal of Vegetation Science, reveal the record is contested between South America's tropical rainforests and Central European meadows. "The coexistence of large numbers of species in one space and the questions it raises have long fascinated...

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
2013-04-19 18:13:27

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
2013-04-19 16:42:25

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...
