Seals Protect Brain, Conserve Oxygen By Turning Off Shivering Response On Icy Dives
10-11-2006 · ScienceDaily
Seals shiver when exposed to cold air but not when diving in chilly water, a finding that researchers believe allows the diving seal to conserve oxygen and minimize brain damage that could result from long dives. This research into hypothermia and hypoxia is important to treating people who are hypothermic or who have suffered hypoxia following cardiac arrest, stroke, etc. Research was presented at the American Physiological Society conference, " Comparative Physiology 2006: Integrating Diversity."

Study challenges belief that tree frogs depress metabolic rate after 'waxing' themselves
10-16-2006 · EurekAlert!
Researchers from the University of Florida explore wiping behaviours in a tree frog that waxes itself, and test whether these frogs become dormant to conserve energy during dehydration. Many amphibians have skin that offers little resistance to evaporative water loss. To compensate, these and some other arboreal frogs secrete lipids and then use an elaborate series of wiping motions to rub the waxy secretions over their entire bodies.

CGIAR climate change research
12-04-2006 · EurekAlert!
The Consultative Group on International Agricultural Research (CGIAR), in consultation with the global environmental change science community, is refining a comprehensive climate change agenda that is already generating climate-resilient innovations, including crops bred to withstand heat, salt, waterlogging and drought, and more efficient farming techniques to help poor farmers better use increasingly scarce water and fragile soil. Researchers are also focusing on boosting agriculture's role in reducing climate-altering greenhouse gases.

How trees manage water in arid environments
01-03-2007 · EurekAlert!
Mountain-top forests in Arizona have survived a three-year period of extreme drought. These conifers have evolved the ability to "turn themselves on" whenever water is available, both in winter when such trees elsewhere are dormant and in summer when sudden heavy rains must be exploited quickly. When water is scarce, the trees greatly reduce their activity.

New system of wastewater treatment could reduce the size of treatment plants by half
08-09-2007 · EurekAlert!
UGR researchers have developed new technologies to obtain cheaper water of higher quality that would also reduce unwanted mud production. Research is particularly interesting if the current drought is taken into account, as well as the lack of space many municipalities have when the number of inhabitants grows, which makes it impossible to enlarge their water treatment plants. Results of this research were recently published in several prestigious scientific journals: Journal of Environmental Science Health, Part A; and Applied Microbiology and Biotechnology.

US needs to plan for climate change-induced summer droughts
02-16-2007 · EurekAlert!
The western United States has experienced increasing drought conditions in recent years -- and conditions may worsen if global climate change models are accurate -- yet the country is doing little to prepare for potential catastrophe. The U.S. should consider a national drought policy to help achieve sustainable water for drinking, agriculture and fisheries, and also manage water supplies to protect environmental values and protect urban property from sea level rise and extreme weather events.

Moss genome shows how plants invaded the land and learned to survive heat and drought
12-13-2007 · EurekAlert!
A dainty yet ephemeral moss is the latest organism to have its genome sequenced, providing scientists with keys to the genetic changes that allowed aquatic plants to venture onto land. The genes for tolerance to desiccation, for example, may aid researchers seeking to develop drought-tolerant biofuel feedstocks. Proposed by UC Berkeley and Washington University botanists, the moss genome sequencing was conducted by DOE's Joint Genome Institute and annotated by scientists from more than 40 institutions.
