Asian carp more adaptable than first thought or evolving

A Purdue researcher says Asian carp are going where experts thought the fish would not. Specifically, Forestry and Natural Resources Assistant Professor Reuben Goforth says the species are showing greater flexibility in the location and conditions under which they can spawn.

He says what’s not known is if they already have the ability to adapt, or if the fish is evolving in U.S. waters.

“In terms of their evolution, it’s certainly not unheard of for a species to be able to undergo in some level of microevolution to become adapted to new environments relatively quickly.”

French study points to pesticides as cause of CCD

Researchers believe they are closing in on what is causing the decline in the number of honeybees.

A new study by French scientists points to a pesticide called neonicotinoid (NEE-oh-NIK-uh-tin-oyd).

Purdue Entomologist Christian Krupke says there seems to be more of a direct link between chemical use and Colony Collapse Disorder. He says specifically, this nicotine-based class of pesticides. The French researchers gave a non-lethal dose to honeybees they studied, which led to behavioral changes.
