Creepy Crawlers Play An Important Role In Structure Of Grasslands
2014-10-07 03:19:26

Provided by Kevin Dennehy, Yale School Forestry & Environmental Studies When asked to describe a forest or a meadow, most people would probably begin with the plants, the species diversity, or the color of the foliage. They probably wouldn’t pay much attention to the animals living in the soil. But a new Yale-led study shows the critical importance of earthworms, beetles, and other tiny creatures to the structure of grasslands and the valuable ecosystem services they provide....

grassland in the Flint Hills
2014-08-04 02:00:31

Greg Tammen, Kansas State University Kansas State University researchers have completed a 20-year study that looks at the consequences of burning Flint Hills prairie at different times of the year. It finds that burning outside of the current late spring time frame has no measurable negative consequences for the prairie and, in fact, may have multiple benefits. The study was conducted by Gene Towne, research associate and the Konza Prairie Biological Station fire chief, and Joseph...

Self-Organization Most Likely Cause Of Namibian Fairy Circles: Study
2014-05-21 07:09:14

Lawrence LeBlond for redOrbit.com - Your Universe Online A new study of mysterious bare “fairy circles” of ground dotting the landscape in the Namibian grasslands have been determined to not be the work of sand termites as had been previously suggested, but rather self-organization. Scientists have been researching these crop circle-style, bare patches of ground for decades trying to come up with a reasonable explanation for why these formations occur. Research published last March...

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...

A study of grasslands on six continents suggests a way to counteract the human-made overdose of fertilizer that threatens to permanently reduce their biodiversity: let grazing animals crop fast growing grasses. Grazers allow sunlight to reach ground level, encouraging other plants' growth, according to the study published online March 9, 2014 in Nature. College Park, MD (PRWEB) March 10, 2014 A comparative study of grasslands on six continents suggests there may be a way to counteract...

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...

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...

Demise Of Tallgrass Prairies Was Due To Extremely Fertile Soil
2013-11-01 07:11:49

April Flowers for redOrbit.com - Your Universe Online They have all but disappeared, but America's once-abundant tallgrass prairies were home to dozens of species of grasses that could grow to the height of a man, hundreds of species of flowers, and herds of roaming bison. Now, a team of researchers from the University of Colorado Boulder (CU-Boulder) has gotten a peek at a vitally important, yet rarely studied community of those tallgrass prairies. The study, published in Science,...

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...
