Knowledge gained from scientific data and from firsthand experience are two different things. When combined, however, these two sources can offer a more complete picture than either one alone. Researchers applied this concept to the creation of state-and-transition models—studies of vegetation dynamics within ecological sites—using the expertise of conservation land managers and the local knowledge of ranchers.
Wind blowing on the ocean is a crucial factor mixing carbon dioxide into the ocean depths. For more than two decades scientists have suspected there’s another source of mixing at ocean fronts. However, there’s never been a way to get enough measurements of such a front to prove this – until now.
Chronic inhalation of polluted air appears to activate a protein that triggers the release of white blood cells, setting off events that lead to widespread inflammation, according to new research in an animal model.
The ongoing spread of non-native mussels in the Great Lakes has caused "massive, ecosystem-wide changes" throughout lakes Michigan and Huron, two of the planet's largest freshwater lakes, according to a new University of Michigan-led study.
A South Dakota State University researcher is using museum collections to assemble a metrics database on perhaps 60,000 duck eggs representing at least 40 species and subspecies of ducks found in North America. What she learns could ultimately add new knowledge about how waterfowl respond to climate cycles and long-term climate change.
For thousands of years, the native peoples living along the world’s northernmost seas have forged an intimate relationship with their environment. The indigenous inhabitants of the Arctic Ocean’s Chukchi and Beaufort seas view themselves as tied to the sea, ice, and other elements of the natural world—even spiritually connected to the animals they hunt and regard as offerings toward the continued subsistence of their people and way of life.
One year after the BP Deepwater Horizon oil rig explosion on the Gulf Coast, new research from the Carsey Institute at the University of New Hampshire shows that despite the roughly equivalent economic compensation, Louisiana and Florida residents differ in perceptions about the current and long-term effects of the largest marine oil spill in U.S. history.
Extracting natural gas from the Marcellus Shale could do more to aggravate global warming than mining coal, according to a Cornell study. Ecologist Robert Howarth warns about methane leaking into the atmosphere during hydraulic fracturing.
For the fifth consecutive year, the University of Michigan Hospitals and Health Centers has been given the Environmental Leadership Circle Award, Practice Greenhealth's most prestigious honor.
The turmoil in oil-producing nations is triggering turmoil at home, as rising oil prices force Americans to pay more at the pump. Meanwhile, there’s a growing industry that’s promising jobs and access to cheaper energy resources on American soil, but it’s not without its controversy. Deborah Kittner, a University of Cincinnati doctoral student in geography, presents, “What’s the Fracking Problem? Extraction Industry’s Neglect of the Locals in the Pennsylvania Marcellus Region,” at the annual meeting of the Association of American Geographers. Kittner will be presenting April 14 at the meeting in Seattle.

In an unprecedented collaborative analysis published in the journal PlosBiology, scientists from 49 nations demonstrated that the ability of reef fish systems to produce goods and services to humanity increases rapidly with the number of species. However, growing human populations hamper the ability of reefs to function normally, and counterintuitively, the most diverse reef fish systems suffer the greatest impairments from stressors triggered by human populations.
Fossil teeth of African animals show that during the past 10 million years, different plant-eating critters began grazing on grass at different times as many switched from a salad-bar diet of tree leaves and shrubs, says a University of Utah study.
Their bench-model scrubber turns carbon dioxide into a useful product.
Analysis published this week in the journal Science shows how declines of bat populations caused by a new wildlife disease and fatalities at industrial-scale wind turbines could lead to substantial economic losses on the farm.
Kunz and his coauthors review the role of bats in providing ecosystem services, focusing primarily on those that regulate and provide services needed to sustain humankind, with a brief overview of supporting and cultural services. One of the grand challenges that society faces is how best to identify, protect and conserve services that are critical for human and ecosystem health.
Cornell University researchers are calling on their colleagues around the world to focus on how aging global populations will intersect with climate change and calls for environmental sustainability.
In a scientific advance literally plucked from the waste heap, scientists today described a key step toward using the billions of pounds of waste chicken feathers produced each year to make one of the most important kinds of plastic.

In the first report on the uptake and internal processing of triclocarban (TCC) in fish, scientists today reported strong evidence that TCC — the source of environmental health concerns because of its potential endocrine-disrupting effects — has a “strong” tendency to bioaccumulate in fish. They presented the findings here today at the 241st National Meeting of the American Chemical Society.
The next-generation battery, like next-generation TV, may be 3-D, scientists reported at the 241st National Meeting and Exposition of the American Chemical Society (ACS) in Anaheim, CA.
