Researchers looking at corals in the western tropical Pacific Ocean have found records linking a profound shift in the depth of the division between warm surface water and colder, deeper water traceable to recent global warming.
Changes in population growth and composition, including aging and urbanization, could significantly affect global emissions of carbon dioxide over the next 40 years, according to a new study in PNAS out next week.
Hopes that coral reefs might be able to survive, and recover from, bleaching caused by climate change may have grown dimmer for certain coral species, according to new research by University at Buffalo marine biologists published this week in PLoS One.
Bioasphalt® developed by Iowa State University's Christopher Williams and produced by Avello Bioenergy Inc., a company started by three Iowa State graduates, will be tested on a Des Moines bicycle trail. Williams said asphalt mixtures derived from plants and trees could replace petroleum-based mixes. And that could provide markets for Iowa crop residues and business opportunities for Iowans.
Study of ocean migration indicates that local management of the population may be insufficient and supports recently proposed listing for Atlantic sturgeon under U.S. Endangered Species Act
A UNH professor of biochemistry and her colleagues have identified the first reproductive hormone of the hagfish – a gonadatropin -- representing a significant step toward unraveling the mystery of hagfish reproduction. At 500 million years old, hagfish are the oldest living vertebrate, predating the dinosaurs.
New research adds to growing evidence that, even though the temperature increase associated with a warming climate has been smaller in the tropics, the impact of warming on life could be much greater there than in colder climates.
A new study finds that fish located near coal-fired power plants have lower levels of mercury than fish that live much further away. The surprising finding appears to be linked to high levels of another chemical, selenium, found near such facilities, which unfortunately poses problems of its own.
It just got easier to pinpoint biological hot spots in the world’s oceans where some inhabitants are smaller than, well, a pinpoint.
Babies whose mothers had relatively high levels of the chemical DDE in their blood were more likely to both grow rapidly during their first 6 months and to have a high body mass index (BMI) by 14 months, according to a team of scientists based in Barcelona, Spain. DDE, an endocrine disrupter, is a by-product of the pesticide DDT.
Some fisheries in the United States are poised to undergo major changes in the regulations used to protect fish stocks, and Quinn Weninger and Rajesh Singh have estimated that the new system will be an economic boon to the fishing industry. The two estimated harvesting costs under the old system and compared that to the newly proposed fishing regulations that lift many restrictions that cause inefficiency while still limiting amounts to be harvested.
Nathan Pelletier and Peter Tyedmers of the Dalhousie University School for Resource and Environmental Studies have released a paper focusing on the environmental implications of the livestock industry. The paper illustrates a number of worrying statistics that call into question the sustainability of the livestock industry. If we continue to increase our consumption of livestock, we will fatally impact our environment on a local and global scale.
As the century warms, tropical forests will be at risk from many threats, especially conversion to cropland to sustain the population. A new report shows that crop productivity improvements and carbon emission limits together could prevent widespread tropical deforestation over the next 100 years.
Ambitious plans to expand acreage of bioenergy crops could have a major impact on birds in the Upper Midwest, according to a study published today (Oct. 4) in the online edition of the Proceedings of the National Academy of Sciences.
Reefs of deep-sea corals are discovered for the first time in the Mediterranean, offshore of Israel, by the "Nautilus" cruise. "It's like finding a flourishing oasis in the middle of the desert," said Dr. Yizhaq Makovsky.
What does it take to save a species in the 21st century? The specter of climate change, with predicted losses to biodiversity as high as 35 percent, has some scientists and managers considering taking their conservation strategies on the road.
The U.S. Department of Agriculture (USDA) today released a new study by scientists and conservationists showing that non-federal rangelands in the Western United States are productive, but that non-native grasses and shrubs pose a potential threat to the rangelands’ productivity.
The world’s rivers, the single largest renewable water resource for humans and a crucible of aquatic biodiversity, are in a crisis of ominous proportions, according to a new global analysis.
An article published online September 29 ahead of print in the peer-reviewed journal Environmental Health Perspectives (EHP) relates how the finding of unexpected biomarker results during a pilot community health study of school-age girls led to a debate about how and when to inform the study families. Ultimately, the transdisciplinary research team, which included community breast cancer advocates, was able to draw on its diverse experience and knowledge of ethical principles to craft a comprehensive plan to communicate the findings to the families.
A Wildlife Conservation Society (WCS) study on nesting birds in Argentina finds that increasing temperatures and rainfall—both side effects of climate change in some parts of the world—could be bad for birds of South America, but great for some of their parasites which thrive in warmer and wetter conditions.
The more complex a plant or animal, the more difficulty it should have adapting to changes in the environment. That's been a maxim of evolutionary theory since biologist Ronald Fisher put forth the idea in 1930.
Rising CO2 levels in atmosphere contribute to lower ocean pH levels, which interfere with development of shellfish larvae.
Dalhousie University's newest academic building, is also the greenest place on campus and sets a new standard for green buildings in the university community.
Florida State University oceanographer Jeff Chanton is part of an international team embarking on a new study of permafrost decomposition in arctic Sweden. What he and his fellow researchers discover there may be critical given the permafrost’s key role in climate change, and vice versa.
Jules White, with the Virginia Tech College of Engineering, seeks to create a massive data collection system that would rely on information captured by “citizen scientists” who would use devices such as smart phones to take photographic evidence from the site of disaster areas. Once collected at a single source, scientists and other responders could quickly sift through data, and decide how best to react.
New research shows a mid-20th century pause in global warming in the Northern Hemisphere might have resulted from an abrupt cooling event centered over the North Atlantic around 1970.
After the failure of the Deepwater Horizon oil well last spring, nearly 2 million gallons of dispersant were released into the Gulf of Mexico. The long-term effect of the dispersant on ecosystems, wildlife and humans remains to be seen.

The Clean Energy Trust has received a $1 million grant from the U.S. Department of Energy to help transfer research from the University of Chicago, Argonne National Laboratory, and other Illinois universities and science labs into clean-energy technologies and viable businesses.
So-called green chemists use all the tools and training of traditional chemistry, but instead of ending up with toxins that must be treated after the fact, they aim to create industrial processes that avert hazard problems altogether. The result is new materials that are not only safer to use but less expensive to make. Yet a decade after the phrase “green chemistry” was coined, less than 1% of patents in chemical-heavy industries are green.
As a member of the recently announced clean vehicles consortium, part of the U.S.-China Clean Energy Research Center, Oak Ridge National Laboratory researchers are focusing on a suite of technologies to put more electric and hybrid vehicles on the road.
Though the recent oil leak in the Gulf of Mexico caused by the BP/Deep Water Horizon oilrig explosion is no longer leading headlines, this fall, the disaster will be a major topic of conversation and study in environmental science classrooms around the country.

A new peer-reviewed paper by the Wildlife Conservation Society and other groups reveals an ominous finding: most of the world’s last remaining tigers—long decimated by overhunting, logging, and wildlife trade—are now clustered in just six percent of their available habitat.
The existing and potential benefits of clean energy to the upstate region will be touted in a half-day program hosted by Ithaca College. “The Clean Energy Summit: Re-Imagining Upstate New York’s Energy Future” is scheduled for Friday, Sept. 17, in the Ithaca College Campus Center.
August 2010 was the second hottest August in the 32-year satellite dataset, with a global temperature that was only 0.01 C cooler than the record set in August 1998. That difference is within the error range, so the two months might as well be tied for the hottest August in 32 years.
A white paper on California’s Proposition 23 finds the initiative would create legal turmoil, cut state revenue, and jeopardize clean energy jobs. Prop. 23 would also slow state efforts to reduce climate change and could have a domino effect nationwide.
The United States is in the thick of a “green trend.” Increased awareness of and commitment to sustainability and improving the environment through reduced carbon emissions and energy use have led to more consumer demand for “green” products—including green construction. Even with the downturn in the housing market, a 2008 poll showed that 91 percent of registered voters nationwide would still pay more for a house if that meant a reduced impact on the environment.

Something has been gobbling up a "doughnut" of phytoplankton in southern Lake Michigan, and it looks as though the culprit is the quagga mussel, a European mollusk about the size of a fat lima bean.
The National Institutes of Health will launch a multi-year study this fall to look at the potential health effects from the oil spill in the Gulf region.
The world’s most established fisheries certifier is failing on its promises as rapidly as it gains prominence, according to the world’s leading fisheries experts from the University of British Columbia (UBC), Scripps Institution of Oceanography at the University of California at San Diego and elsewhere.
The Wildlife Conservation Society’s New York Aquarium announced today the launch of the New York Seascape initiative—a conservation program designed to restore healthy populations of local marine species—many of them threatened—and to protect New York City and area waters, which are vital to wildlife and key to economic and cultural vitality.
What is Agriculture’s role in greenhouse gas emissions, capture?
With a simple click of the camera, scientists from the Wildlife Conservation Society and Zoological Society of London have developed a new way to accurately monitor long-term trends in rare and vanishing species over large landscapes.
Proponents of organic farming often speak of nature's balance in ways that sound almost spiritual, prompting criticism that their views are unscientific and naïve. At the other end of the spectrum are those who see farms as battlefields where insect pests and plant diseases must be vanquished with the magic bullets of modern agriculture: pesticides, fungicides and the like.
A molecular biologist will bring dozens of tiny, transparent animals that live in Gulf Coast waters back to his campus laboratory as part of an effort to better understand the oil spill’s long-term impact on the coastal environment and creatures living there.
The Wildlife Conservation Society (WCS) and the Zoological Society of London (ZSL) are requesting that the Government of Tanzania reconsider the proposed construction of a commercial road through the world’s best known wildlife sanctuary—Serengeti National Park—and recommend that alternative routes be used that can meet the transportation needs of the region without disrupting the greatest remaining migration of large land animals in the world.
