Prompted by the Deepwater Horizon oil spill, a UC Santa Barbara scientist has come up with a new way of predicting how contaminants like oil will spread. He was able to forecast several days in advance that oil from that spill would wash ashore in particular parts of the Gulf of Mexico.

Side-by-side comparisons of organic and conventional strawberry farms and their fruit found the organic farms produced more flavorful and nutritious berries while leaving the soil healthier and more genetically diverse.

The use of salt to deice pavement can leave urban streams toxic to aquatic life, according to a new U.S. Geological Survey study on the influence of winter runoff in northern U.S. cities, with a special focus on eastern Wisconsin and Milwaukee.

Previous research has claimed that the reintroduction of wolves to Yellowstone National Park in 1995 is helping restore quaking aspen in risky areas where wolves prowl. But apparently elk hungry for winter food had a different idea. They did not know they were supposed to be responding to a "landscape of fear."

Global degradation of ecosystems is widely believed to threaten human welfare, yet accepted measures of well-being show that it is on average improving globally, both in poor countries and rich ones. A team of authors writing in the September issue of BioScience dissects explanations for this "environmentalist's paradox."

Inorganic elements known to be toxic at low concentrations are being discharged to air and water by oilsands mining and processing according to University of Alberta (U of A) research findings being published this month in one of the world's top scientific journals.

Tests of the potential vaccine against "Ich" ― the dreaded "white-spot" disease that plagues fish in commercial fish farms, public aquariums, pet fish retail outlets, and home aquariums ― are raising hopes for finally controlling the disease, scientists reported here today at the 240th National Meeting of the American Chemical Society (ACS).

Plants have developed a sophisticated defense system. They can not only directly fend off herbivores by producing toxins, but also do so indirectly by emitting odorant molecules into the atmosphere that are perceived by predatory insects; these predators are lured to the attacked plant and feed on the herbivore or parasitize it – thereby providing a benefit for the plant.
