Eddies Warm Up The Ocean
Eddies appear in the ocean like in the atmosphere. Atmospheric eddies are short-lived, extremely speedy, and often very hazardous. Oceanic eddies are slower and can be observed only with the use of special equipment, but these eddies gently mixing ocean waters affect the climate in general. For more than ten years specialists from the Pacific... view more... (2002-02-19)
Symbiotic fungi promote invasion into diverse plant communities (Rudgers et al.)
The biodiversity of a community can affect its functional properties, such as its productiveness or its ability to resist invasion by exotic species. Many grass species host fungi in their leaves that can render them more resistant to herbivory, drought, and competition. In a forthcoming issue of Ecology Letters, Rudgers, Koslow and Clay... view more... (2003-12-10)
Atmospheric scientists trace the human role in Indonesian forest fires
Severe fires in Indonesia - responsible for some of the worst air quality conditions worldwide - are linked not only to drought, but also to changes in land use and population density, according to a new study in Nature Geoscience led by Robert Field of the University of Toronto. view more (2009-02-23)
How trees manage water in arid environments
The summer of 2006 was the second warmest in the continental United States since records began in 1895, according to the National Climatic Data Center. Moderate to extreme drought conditions were evident in about 40 percent of the country. view more (2007-01-05)
A link between greenhouse gases and the evolution of C4 grasses
How a changing climate can affect ecosystems is an important and timely question, especially considering the recent global rise in greenhouse gases. view more (2007-12-21)
Hybrid bluegrasses analyzed for use in transition zone
The transition zone can be one of the most challenging places to maintain high-quality turfgrass; changeable growing conditions in these regions often prove too hot for some grasses and too cold for others. Finding turfgrass that thrives in these challenging environments can be perplexing for turf management professionals and homeowners alike. view more (2009-11-05)
Lake Mead Could Be Dry by 2021
There is a 50 percent chance Lake Mead, a key source of water for millions of people in the southwestern United States, will be dry by 2021 if climate changes as expected and future water usage is not curtailed, according to a pair of researchers at Scripps Institution of Oceanography, UC San Diego. view more (2008-02-13)
Researchers to determine if aeration reduces compaction, runoff on no-till fields
Much of Texas' wheat may be grazed as a part of a dual-use crop. But many fields are still prepared using conventional tillage, which may not efficiently capture rainfall - a key to economic success in a semi-arid environment, said a Texas AgriLife Research scientist. view more (2009-04-02)
Surprising Killer of Southeastern Salt Marshes: Common Sea Snails
Periwinkles, the spiral-shelled snails commonly found along rocky U.S. shorelines, play a primary role in the unprecedented disappearance of salt marsh in the southeastern states, according to new research published in Science. view more (2005-12-16)
Climate change: The rice genome to the rescue
The sequencing of the rice genome could help mitigate the impact of climate change on the world's poor. view more (2006-03-28)
Predetermined winners and losers in the Ice Age extinction game
The Quaternary ice ages caused severe decimation of the European tree flora. Of the diverse pre-Ice Age tree flora only a minority of the genera are still widespread in Europe. Most of the remainder have been lost altogether from the European flora and now only occurs in Asia and/or North America, although some persist as relicts in southern... view more... (2003-07-02)
Droughts and reservoirs: Finding storage space underground
Odd as it sounds, in some places the smartest way to safeguard the water supply is to let it drain out of the reservoirs and soak into the ground. view more (2006-09-19)
Vine invasion? UWM ecologist looks at coexistence of trees and lianas
Among the hundreds of species of woody vines that University of Wisconsin-Milwaukee ecologist Stefan Schnitzer has encountered in the tropical forests of Panama, the largest has a stalk nearly 20 inches in circumference. view more (2008-08-06)
`Nature` highlights use of satellite imagery to study massive CO2 release in Indonesian fires
Writing in tomorrow’s issue of Nature magazine, a team of European and Indonesian scientists used satellite imagery from ESA’s ERS and NASA’s Landsat satellites to help measure the huge amounts of carbon dioxide gas released into the atmosphere by 1997-98 fires in the tropical bush of Indonesia. A series of peatland and forest... view more... (2002-11-06)
Accord on international waterways not followed
The use of international watercourses, that is, rivers and lakes shared by two or more states, has long been the object of numerous international agreements. States enter agreements with each other regarding the distribution of the water itself as a resource, maritime use of the waterway, or the extraction of water resources (fish stocks,... view more...

New study links western tree mortality to warming temperatures, water stress
A new study led by the U.S. Geological Survey and involving the University of Colorado at Boulder indicates tree deaths in the West's old-growth forests have more than doubled in recent decades, likely from regional warming and related drought conditions. view more (2009-01-23)
NASA uses satellite to unearth innovation in crop forecasting
Soil moisture is essential for seeds to germinate and for crops to grow. But record droughts and scorching temperatures in certain parts of the globe in recent years have caused soil to dry up, crippling crop production. view more (2009-05-27)
New publication shows index insurance has potential to help manage climate risks and reduce poverty
Climate has always presented a challenge to farmers, herders, fishermen and others whose livelihoods are closely linked to their environment, particularly those in poor areas of the world. view more (2009-06-24)
First all-African produced genetically engineered maize is resistant to maize streak virus
Maize streak viruses (MSV), geminiviruses that can destroy most of a maize crop, are endemic to sub-Saharan Africa and adjacent Indian Ocean islands where they are transmitted by leafhoppers in the genus Cicadulina. view more (2007-07-09)
New Water Management Tool May Help Ease Effects of Drought
Continued improvement of climate forecasts is resulting in better information about what rainfall and streamflow may look like months in advance. view more (2009-11-13)
