"As climate change transforms their habitat, some animals are already on the move. But a new analysis from the University of Washington warns that many species won't be able to run fast enough to survive a warming world."

"The eastern diamondback rattlesnake, North America's largest venomous snake, may need its own antidote. The U.S. Fish and Wildlife Service is considering adding the reptile to the Endangered Species List to restrict its hunting, killing and sale."

"'We are going to do our best to keep these beautiful animals on the planet with us,' said Dan Everson, Deputy Field Supervisor for the U.S. Fish and Wildlife service in Alabama.

"Chemical titans say they have what farmers need to fight superweeds, but will they only be adding to a growing problem?"

"A fast-spreading plague of 'super weeds' taking over U.S. farmland will not be stopped easily, and farmers and government officials need to change existing practices if food production is to be protected, industry experts said on Thursday."

"More people on the East Coast are acquiring a taste for snakehead, an exotic fish that's moved here from Asia. But the fish are still multiplying and spreading."

"It’s the kind of scenario that might evolve in Hollywood: A college professor detects drug-resistance genes collecting in local wetlands, where they survive for weeks and are spread far and wide by seabirds.

But the discovery of extra-hardy DNA flourishing on the edge of San Diego isn’t science fiction. It’s the result of research by David Cummings, a microbiologist at Point Loma Nazarene University.

"Plants are flowering faster than scientists predicted in response to climate change, research in the United States showed on Wednesday, which could have devastating knock-on effects for food chains and ecosystems. Global warming is having a significant impact on hundreds of plant and animal species around the world, changing some breeding, migration and feeding patterns, scientists say."

"Some bomb-sniffing dogs trained to help fight terrorism are turning their olfactory attention toward a different scourge: Burmese pythons in Florida's Everglades National Park."
