Crossing paths in plants
On Monday 31 March ecologists will meet with molecular biologists at the University of Southampton for the most novel and broad-ranging scientific session of its kind. They will present findings in Session C5/P3 which show that the biochemical pathways which influence a plant's response to stimuli... view more (2003-03-26)

Drought sensitivity shapes species distribution patterns in tropical forests
Looking at a rainforest it's easy to see that there are hundreds of different tropical plant species that inhabit the forest. Although the patterns of plant distributions in tropical forests have been widely studied, the reasonings behind these patterns are not as well known.   view more (2007-05-15)

Drought limits tropical plant distributions, scientists at the Smithsonian report
Drought tolerance is a critical determinant of tropical plant distributions, researchers working at the Smithsonian Tropical Research Institute in Panama report in the journal Nature, May 3.   view more (2007-05-03)

Salt of the Earth
A yeast gene responsible for salt tolerance has successfully been used to grow tobacco in a salty environment lethal to most plants. Dr Janey Henderson and Professor Phil Harris from Coventry University inserted the halotolerance gene HAL1 from yeast into a tobacco plant. HAL1 has previously been... view more (2001-04-04)

Beavers can help ease drought
They may be considered pests, but beaver can help mitigate the effects of drought, and because of that, their removal from wetlands to accommodate industrial, urban and agricultural demands should be avoided, according to a new University of Alberta study.   view more (2008-02-21)

Breakthrough in environmental monitoring from space
Scientists working at the Joint Research Centre of the European Commission have developed a new way to interpret data from satellites observing the earth. The satellites monitor the nature, state and evolution of the earth's vegetation. This enhanced monitoring capacity will make it more possible... view more (2004-12-17)

Drought tolerance in potatoes
Climate change is expected to exacerbate drought events throughout the world, resulting in large-scale ecosystem alteration and failure of drought-sensitive crops.   view more (2008-06-30)

Amazon forest shows unexpected resiliency during drought
Drought-stricken regions of the Amazon forest grew particularly vigorously during the 2005 drought, according to new research.   view more (2007-09-24)

Why juniper trees can live on less water
An ability to avoid the plant equivalent of vapor lock and a favorable evolutionary history may explain the unusual drought resistance of junipers, some varieties of which are now spreading rapidly in water-starved regions of the western United States, a Duke University study has found.   view more (2008-02-28)

MONSOON IN WEST AFRICA:CLASSIC CONTINUITY HIDES A DUAL-CYCLE RAINFALL REGIME
Since the end of the 1960s West Africa has continuously been suffering hard drought. The rainfall deficit for the 1970s and 1980s, calculated to compare with the 1950s and 1960s, thus reached as high as 50% over the northern part of the Sahel. The hydrological cycle as a whole is affected by this... view more (2003-01-28)

Why UK households should splash out on water meters

Livestock interventions can protect lives, livelihoods
Pastoralist communities in dryland areas of Africa are reliant on livestock as sources of food, income and social support. However drought is common in sub-Saharan Africa, making these communities vulnerable to loss of livestock when rains fail.   view more (2007-04-24)

Congo River Basin : Geology And Soil Type Influence Drought Impact
The Congo drainage basin is situated in Central Africa. Its hydrological system straddles several countries (Congo and the Democratic Republic of Congo for the most part, but also Angola, Cameroon, the Central African Republic, Zambia and Tanzania, stretching through Lake Tanganyika). The River... view more (2002-01-03)

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)

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... view more (2005-02-04)

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... 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... 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)

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)

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)

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)

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)

AgriLife Research breeder develops drought-tolerant corn
At the end of the day, drought tolerance in corn has to equate to good yields and good quality, not just good looks, said a Texas AgriLife Research scientist.   view more (2008-08-26)
