Developing biofuel from native perennials instead of corn in the Midwest's rolling grasslands would better protect threatened bird populations, Michigan State University research suggests. Federal mandates and market forces both are expected to promote rising biofuel production, MSU biologist Bruce Robertson says, but the environmental consequences of turning more acreage over to row crops for fuel are a serious concern. Ethanol in America is chiefly made from corn, but research is focusing...

New grasses suggested as alternatives to red fescue Erosion is a significant problem on highway embankments in New England. To mitigate erosion on the regions' highways, slopes are seeded with a grass"“legume mixture that usually including red fescue, a grass preferred for its drought-tolerance and ability to thrive in acidic, infertile soil. "A mixture of red fescue, perennial ryegrass, and kentucky bluegrass is planted to stabilize the soil, but only the red fescue survives long term...

In the minds of many, Miscanthus x giganteus is the forerunner in the race of viable feedstock options for lignocellulosic bioenergy production. But researchers believe "putting all their eggs in one basket" could be a big mistake. Scientists at the University of Illinois recently reported the first natural occurrence in several decades of Miscanthus hybrid plants in Japan. "If M. x giganteus is the only variety available, there are certainly risks involved such as diseases or pests causing...

According to a popular hypothesis, grasses such as maize, sugar cane, millet and sorghum got their evolutionary start as a result of a steep drop in atmospheric carbon dioxide levels during the Oligocene epoch, more than 23 million years ago. A new study overturns that hypothesis, presenting the first geological evidence that the ancestors of these and other C4 grasses emerged millions of years earlier than previously established. The findings are published in the journal Geology. C4 plants...

Innovative research technique reveals C4 grasses older than previously thought A new analysis of fossilized grass-pollen grains deposited on ancient European lake and sea bottoms 16-35 million years ago reveals that C4 grasses evolved earlier than previously thought. This new evidence casts doubt on the widely-held belief that the rise of this incredibly productive group of plants was driven by a large drop in atmospheric carbon dioxide concentrations during the Oligocene epoch. The...

University of North Carolina, Greensboro researchers are studying native grasses to develop a better understanding of the workings of fungal endophytesLegend has it that five railroad surveyors killed by Indians in 1854 in New Mexico lost their lives because they unwittingly allowed their horses to graze on "sleepy grass" the night before. The next morning, under attack, the surveyors jumped on their horses to escape--but the animals were frozen in place. Without the means for a quick...

ALBANY, Ore., Oct. 4 /PRNewswire/ -- Focused on identifying plants and lawn grasses that thrive on less water, the Turfgrass Water Conservation Alliance (TWCA) today announced it has qualified two dozen varieties of drought-tolerant grasses in time for fall planting season. The non-profit organization, made up of leading researchers and seed producers, is dedicated to the discovery, evaluation and development of environmentally green landscape products that can go weeks without water....

A rose by any other name may smell as sweet, but it would no longer be a rose. If a grass is booted out of the grass family, where does it go? Leah Morris and Dr. Melvin Duvall from Northern Illinois University recently investigated the evolution of grasses, one of the most economic and ecologically important plant families, by sequencing the chloroplast DNA of an early diverging grass genus, Anomochloa, and comparing it to the chloroplasts of other grasses. Their results are published in the...

4 grasses offer sustainable strategies for low-input turf Burgeoning restrictions on water use, fertilization, and pesticide application are becoming important considerations in golf course design and management. In response, scientists are searching for sustainable methods to lessen the environmental impact of golf courses. Other factors, including increasing energy costs, human health concerns, and environmental awareness are also prompting turfgrass managers to consider the use of...

As the U.S. Department of Energy (DOE) works toward developing sustainable sources of clean renewable energy, perennial grasses have emerged as major candidates for the commercial production of cellulosic biofuels from feedstocks. However, little is known about the specific biological traits of the grasses that might contribute to their usefulness for energy production, in part because such grasses typically have long lifecycles and possess large, complex genomes, making them difficult to...

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...

Greater Cane Rat, Thryonomys swinderianus
2012-05-16 12:22:36

The greater cane rat (Thryonomys swinderianus) is one of two species of cane rats found in Africa. They prefer to reside in reed beds or riverbanks south of the Saharan Desert. They have adapted well to urbanization and will also live on plantations. The nocturnal greater cane rat lives in small groups that are led by one alpha male and will make their burrows underground or in grasses. The diet of this cane rat consists of cane plants and grasses. When frightened, the greater cane rat will...
