When eradicating invasive species threatens endangered species recovery
Efforts to eradicate invasive species increasingly occur side by side with programs focused on recovery of endangered ones. But what should resource managers do when the eradication of an invasive species threatens an endangered species? In a new study, UC Davis scientists examine that conundrum now taking place in the San Francisco Bay.

Crow or raven? New birdsnap app can help!
Columbia Engineering computer scientists have taken bird-watching to a new level. Using computer vision and machine learning techniques, they have developed Birdsnap, a new iPhone app that is an electronic field guide featuring 500 of the most common North American bird species. The free app, which enables users to identify bird species through uploaded photos, accompanies a visually beautiful, comprehensive website that includes some 50,000 images.

New study finds Antarctic Ice Sheet unstable at end of last ice age
A new study has found that the Antarctic Ice Sheet began melting about 5,000 years earlier than previously thought coming out of the last ice age -- and that shrinkage of the vast ice sheet accelerated during eight distinct episodes, causing rapid sea level rise.

What can plants reveal about gene flow? That it's an important evolutionary force
How much gene flow is there between plant populations? How important is gene flow for maintaining a species' identity and diversity, and what are the implications of these processes for evolution, conservation of endangered species, invasiveness, or unintentional gene flow from domesticated crops to wild relatives?

Vines choke a forest's ability to capture carbon, Smithsonian scientists report
As tropical forests take over abandoned agricultural land, scientists expect these new forests to mop up industrial quantities of atmospheric carbon. New research by Smithsonian scientists shows increasingly abundant vines could hamper carbon uptake and may even cause tropical forests to lose carbon.

A new concept to improve power production performance of wind turbines in a wind farm
A modern wind farm usually consists of multiple wind turbines arranged in an organized pattern or array. Wake interferences among wind turbines have been found to affect the performance of the wind turbines significantly. In 2014(5) issue of Science China: Physics, Mechanics & Astronomy, the effects of relative rotation direction of wind turbines on the wake interferences among tandem turbines were studied for improved power production performance of wind turbines in a wind farm.
