Study finds weather extremes harmful to grasslands

ScienceDaily: Fluctuations in extreme weather events, such as heavy rains and droughts, are affecting ecosystems in unexpected ways -- creating "winners and losers" among plant species that humans depend upon for food. Arizona State University investigators conducted a six-year experiment on the effects of climatic variability on desert grassland. The study revealed that when unpredictable weather patterns create alternating wet and dry years, ecosystem productivity declines -- mostly because grasses diminish,...

Millions of Acres of Grasslands Cleared For Biofuel Crops in U.S., Study Finds
2015-04-06 17:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: Biofuel crops expanded onto 7 million acres of new land in the U.S. over a recent four-year period, replacing millions of acres of grasslands, according to new research from the University of Wisconsin. Using high-resolution satellite imagery, the researchers calculated that converting grasslands to croplands for corn and soy biofuels could have emitted as much carbon dioxide as 34 coal-fired power plants operating for one year, or the equivalent of an additional 28 million cars on the road. Nearly...

Trees Threaten Growing Grasslands
2014-09-26 20:05:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Trees are currently threatening growing grasslands, turning tallgrass prairies into shrublands and forests, and a pair of researchers is concerned that if nothing is done to stop or slow down this process, an important part of the ecosystem may soon be lost. Two Kansas State University biologists, doctoral student Allison Veach and professor Walter Dodds, are researching grassland streams and the expansion of nearby woody vegetation, such as trees and shrubs, to see what can be done to save growing...

Change in critical grasslands diminishing cattle production
2014-08-18 18:49:00| Climate Ark Climate Change & Global Warming Newsfeed
ASU: Half of the Earths land mass is made up of rangelands, which include grasslands and savannas, yet they are being transformed at an alarming rate. Woody plants, such as trees and shrubs are taking over, leading to a loss of critical habitat and causing a drastic change in the ability of ecosystems to produce food specifically meat.
