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.

Long-Term Studies Detect Effects of Disappearing Snow and Ice

Regions of Earth where water is frozen for at least a month each year are shrinking as a result of global warming. Some of the effects on ecosystems are now being revealed through research conducted at affected sites over decades

Rena's Owner Charged in Court

Daina Shipping Co., a Greek company, has been charged under section 338(1B) and 15(B) of the Resource Management Act of 1991 and could face significant fines.

Is Rainfall a Greater Threat to China's Agriculture than Warming?

New research into the impact of climate change on Chinese cereal crops has found rainfall has a greater impact than rising temperature. The research, published in the Journal of the Science of Food and Agriculture found that while maize is sensitive to warming increases in temperature from 1980 onwards correlated with both higher and lower yields of rice and wheat.

History of Abandoned Urban Sites Found in Soil

Old houses and vacant lots may not look like much to the naked eye, but to some, the site is better than gold. Excavations over the years can create a challenge to study what's left behind and often appears as if dirt and debris ended up mixed in a blender then pressed by a giant trash compactor.

Impact of Warming Climate Doesn't Always Translate to Streamflow

An analysis of 35 headwater basins in the United States and Canada found that the impact of warmer air temperatures on streamflow rates was less than expected in many locations, suggesting that some ecosystems may be resilient to certain aspects of climate change.

Long-term Research Reveals Causes and Consequences of Environmental Change

As global temperatures rise, the most threatened ecosystems are those that depend on a season of snow and ice, scientists from the nation's Long Term Ecological Research (LTER) Network say."The vulnerability of cool, wet areas to climate change is striking," says Julia Jones, a lead author in a special issue of the journal BioScience released today featuring results from more than 30 years of LTER, a program of the National Science Foundation (NSF).

Solar Reactor May Enable Clean Fuel Derived from Sunlight

Producing hydrogen from non-fossil fuel sources is a problem that continues to elude many scientists but University of Delaware’s Erik Koepf thinks he may have discovered a solution.



Fasting for Lent Forces Hyenas to Change Diet

Many Christians give up certain foods for Lent, however ecologists have discovered these changes in human diet have a dramatic impact on the diet of wild animals.

Green Homes Use 80 Percent Less Energy

Clever, inexpensive design can cut the energy used in new homes by up to 80 percent, says a Queensland University of Technology (QUT) researcher.

Mapping Grasslands for Biofuel Potential

USGS scientists have developed a new method for mapping grasslands that demonstrate high potential for biofuel crops with relatively little energy input and environmental impact.

Assessing Protected Area Effectiveness

A new study published in Conservation Letters aims to measure whether parks and reserves in the tropics succeed in protecting forests.

Sediment Chemicals in Coastal Rivers Overall Lower in U.S. than Worldwide Averages

Almost all the sediment-associated chemical concentrations found in 131 of the nation's rivers that drain to the Atlantic, Pacific and Gulf Coasts are lower than worldwide averages, according to a new study by the USGS.

NRC Releases Report on the State of Polar Regions

The U.S. National Research Council (NRC) released a synthesis of reports from thousands of scientists in 60 countries who took part in the International Polar Year (IPY) 2007-08, the first in over 50 years to offer a benchmark for environmental conditions and new discoveries in the polar regions.

Drawing Connections Between Food Webs

Ecosystems today face various threats, from climate change to invasive species to encroaching civilization. If we hope to protect these systems and the species that live in them, we must understand them — an extremely difficult and time-consuming task, given the world's seemingly endless number of ecosystems, each with its own complex dynamics and relationships.

Earth Institute Researchers Develop Interactive Map of NYC's Energy Use

Midtown Manhattan is red hot; Greenpoint a cool yellow and beige. It’s all a matter of energy: A new interactive, color-coded map created by a team at Columbia’s engineering school allows viewers to pinpoint and compare estimated energy usage, building lot by building lot, throughout New York City.

Approximately 80,000 Acres of Guatemala Forest Protected

The Wildlife Conservation Society (WCS) and partners signed an agreement this month that will safeguard some 80,000 acres of intact forest in Guatemala in the heart of the sprawling Maya Biosphere Reserve. Home to jaguars, macaws, pumas and various wildlife, the protected land will continue to serve as a safe haven to all inhabitants.

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.

Reforestation Efforts Reshape Hawaii's Soil Hydrology

Starting with the arrival of Polynesian settlers in the fourth century, and peaking in the mid-1800s, the destructive forces of wildfires and pests and the grazing of feral pigs, goats, and cattle reduced the native forests of Maui, Hawaii, to just a tenth of their original extent.

Natural River Networks are Essential for Biodiversity

To alter natural waterways is to take a serious risk of endangering species living on the entire length of a river. In a joint project, scientists from EPFL, EAWAG and Princeton University have modeled the flow of organisms living along river networks. Their research will be published this week in the journal PNAS.
