Southern pine beetle impacts on forest ecosystems
Research by USDA Forest Service Southern Research Station (SRS) scientists shows that the impacts of recent outbreaks of southern pine beetle further degraded shortleaf pine-hardwood forest ecosystems in the southern Appalachian region. View More (2012-05-18)
A study points to the importance of seeking new pine varieties resistant to climate change
The radiata pine is the tree species par excellence in the Basque Country's forests. Like other types of pine, the lack of water is one of the factors having the greatest effect on its survival and productivity. View More (2012-04-20)
Stoneflies mapped across Ohio, with implications for water quality and nature conservation
Stoneflies, or Plecoptera, are insects that live in water during immature stages, but are terrestrial as adults. They are among the best bioindicators of river water quality and general landscape disturbance. Anglers often model their dry and wet flies (lures) after these insects. View More (2012-04-13)
Which plants will survive droughts, climate change?
New research by UCLA life scientists could lead to predictions of which plant species will escape extinction from climate change. View More (2012-04-06)
New forage plant prepares farmers for climate changes
Researchers, including plant researchers from the University of Copenhagen, have developed a new type of the corn-like crop sorghum, which may become very significant for food supplies in drought-prone areas. View More (2012-04-05)
Stomata development in plants unraveled -- a valuable discovery for environmental research
Plant leaves are protected from drying out by an airtight wax layer. They breathe and release water through microscopic pores called stomata. View More (2012-04-04)
Study Links Past Changes in Monsoon to Major Shifts in Indian Civilizations
A fundamental shift in the Indian monsoon has occurred over the last few millennia, from a steady humid monsoon that favored lush vegetation to extended periods of drought, reports a new study led by researchers at the Woods Hole Oceanographic Institution (WHOI). View More (2012-03-19)
Time of Year Important in Projections of Climate Change Effects on Ecosystems
Does it matter whether long periods of hot weather, such as last year's heat wave that gripped the U.S. Midwest, happen in June or July, August or September? View More (2012-02-16)
Climate change may increase risk of water shortages in hundreds of US counties by 2050
More than 1 in 3 counties in the United States could face a "high" or "extreme" risk of water shortages due to climate change by the middle of the 21st century. View More (2012-02-16)
Extreme droughts could increase by 15 percent in Spain by the middle of the century
A team at the Polytechnic University of Cartagena has designed a new method for calculating drought trends. Initial results suggest that by the year 2050 there could be a 15% increase compared to the droughts seen in 1990 in the Segura river basin. View More (2012-01-26)
Barley adapts to climate change
The upsurge in droughts is one of the main consequences of climate change, and affects crops in particular. However, Anabel Robredo, a biologist at the University of the Basque Country (UPV/EHU), has confirmed that in the case of barley at least, climate change itself is providing it with self-defence mechanisms to tackle a lack of water.

Van Andel Research Institute Study Provides New Details of Fundamental Cellular Process
A recent Van Andel Research Institute (VARI) study published in the journal Science investigating the molecular structure and function of an essential plant hormone could profoundly change our understanding of a key cell process, and might ultimately lead to the development of new drugs for a variety of diseases.

UMass Amherst Ecologists Call for Screening Imported Plants to Prevent a New Wave of Invasive Species
A recent analysis led by ecologist Bethany Bradley at the University of Massachusetts Amherst suggests that climate change predicted for the United States will boost demand for imported drought- and heat-tolerant landscaping plants from Africa and the Middle East. View More (2012-01-05)
Exploiting Trichoderma: From food security to biotechnology
From improving food security to their use as biotechnology power horses, Trichoderma fungi are increasingly being exploited by industry. View More (2011-12-21)
A major step forward towards drought tolerance in crops
When a plant encounters drought, it does its best to cope with this stress by activating a set of protein molecules called receptors. These receptors, once activated, turn on processes that help the plant survive the stress. View More (2011-12-20)
Scientists forecast crops that adapt to changing weather
Crops that can cope with sudden fluctuations in the weather could be developed, thanks to fresh discoveries about the survival mechanisms of plants. View More (2011-12-14)
Climate change blamed for dead trees in Africa
Trees are dying in the Sahel, a region in Africa south of the Sahara Desert, and human-caused climate change is to blame, according to a new study led by a scientist at the University of California, Berkeley. View More (2011-12-13)
Climate change effect on release of CO2 from peat far greater than assumed
Climate change effect on release of CO2 from peat far greater than assumed Drought causes peat to release far more carbon dioxide into the atmosphere than has previously been realised. View More (2011-11-21)
ICRISAT-led team cracks pigeonpea genome
Hyderabad, India and Shenzhen, China, 06 November 2011 - Once referred to as an "orphan crop" mainly grown by poor farmers, pigeonpea is now set to join the world's league of major food crops with the completion of its genome sequence. View More (2011-11-07)
UA scientists find evidence of Roman period megadrought
Almost nine hundred years ago, in the mid-12th century, the southwestern U.S. was in the middle of a multi-decade megadrought. It was the most recent extended period of severe drought known for this region. But it was not the first. View More (2011-11-07)
