Scientists find elephant memories may hold key to survival
A recent study by the Wildlife Conservation Society and the Zoological Society of London (ZSL) suggests that old female elephants-and perhaps their memories of distant, life-sustaining sources of food and water-may be the key to survival during the worst of times. view more (2008-08-12)
Water table depth tied to droughts
Will there be another "dust bowl" in the Great Plains similar to the one that swept the region in the 1930s? view more (2008-09-30)
Counting sheep in climate change predictions
Climate change can have devastating effects on endangered species, but new mathematical models may be able to aid conservation of a population of bighorn sheep. view more (2009-06-01)
Industrialization of China increases fragility of global food supply
Global grain markets are facing breaking point according to new research by the University of Leeds into the agricultural stability of China. view more (2009-01-22)
Dry autumns and winters may lead to fewer tornadoes in the spring, says UGA researcher
Global warming will likely mean more unpredictable weather, scientists say, and a new study by researchers at the University of Georgia pins down, possibly for the first time, how drought conditions in an area's fall and winter may effect tornado activity the following spring. view more (2009-06-24)
Extreme weather postpones the flowering time of plants
Extreme weather events have a greater effect on flora than previously presumed. A one-month drought postpones the time of flowering of grassland and heathland plants in Central Europe by an average of 4 days. view more (2008-11-06)
Drought reduces nitrogen-fixing in legumes
In drought conditions, the capacity for retaining carbon in legume nodules is limited and this may be the reason why there is a drop in nitrogen-fixing in legumes under these conditions. This was the conclusion of Mar'a Dolores G'Ħlvez in defending her PhD thesis at the Public University of Navarre. Her PhD was entitled, "Nodule metabolism... view more... (2005-02-04)
Climate change threatens rice production
Once-in-a-lifetime floods in the Philippines, India's delayed monsoon, and extensive drought in Australia are taking their toll on this year's rice crops, demonstrating the vulnerability of rice to extreme weather. view more (2009-10-16)
New Models of Weather Pattern
For a mathematician, Joseph Biello spends a lot of time thinking about the weather. But the UC Davis assistant professor isn't looking out the office window. He is using mathematical theory to build a model of the Madden-Julian Oscillation, a tropical weather pattern that influences drought and rainfall in the western U.S. view more (2005-12-12)
Tropical Atlantic cooling and African deforestation correlate to drought, report scientists
Against the backdrop of the Montreal Summit on global climate being held this week, an article on African droughts and monsoons, by a University of California, Santa Barbara scientist and others, which appears in the December issue of the journal Geology, underlines concern about the effects of global climate change. view more (2005-12-05)
Annual plants may cope with global warming better than long-living species
Countering Charles Darwin's view that evolution occurs gradually, UC Irvine scientists have discovered that plants with short life cycles can evolutionally adapt in just a few years to climate change. view more (2007-01-09)
Past droughts geographically widespread in the West, according to tree-ring data
When it's dry, it's dry all over, according to a new analysis of more than 400 years of annual streamflow in the Upper Colorado and Salt and Verde river basins. view more (2005-08-19)
Water shortages in Northeast Linked to Human Activity
Recent water shortages in Rockland County, N.Y., reveal an increasing mismatch between water demand and supply following rapid growth in the Northeast during period of abnormally high precipitation. view more (2006-05-18)
Colorado River streamflow history reveals megadrought before 1490
An epic drought during the mid-1100s dwarfs any drought previously documented for a region that includes areas of Arizona, Colorado, New Mexico, Utah and Wyoming. view more (2007-05-18)
Breakthrough in plant research
The research groups of the Department of Biological and Environmental Sciences of the University of Helsinki and the University of California in San Diego have discovered a gene that is centrally involved in the regulation of carbon dioxide uptake for photosynthesis and water evaporation in plants. view more (2008-02-28)
Disease-impact models may rely on incorrect assumptions
Even when we know how a disease affects individual animals, it is challenging to predict what impact it will have on the whole population, and yet predicting how disease affects a population is a primary concern for wildlife conservation and even public health. view more (2006-04-13)
UCR plant scientist's research spawns new discoveries showing how crops survive drought
Breakthrough research done earlier this year by a plant cell biologist at the University of California, Riverside has greatly accelerated scientists' knowledge on how plants and crops can survive difficult environmental conditions such as drought. view more (2009-11-19)
Stressed crops emit more methane than thought
Scientists at the University of Calgary have found that methane emission by plants could be a bigger problem in global warming than previously thought. view more (2009-08-18)
Texas A&M researcher shows possible link between 1918 El Niño and flu pandemic
Research conducted at Texas A&M University casts doubts on the notion that El Niño has been getting stronger because of global warming and raises interesting questions about the relationship between El Niño and a severe flu pandemic 91 years ago. view more (2009-09-15)
New climate record shows century-long droughts in eastern North America
A stalagmite in a West Virginia cave has yielded the most detailed geological record to date on climate cycles in eastern North America over the past 7,000 years. view more (2008-08-19)
