Toxic bird feed

Environmental toxins can move through the food chain with surprising speed, James Larison, an Oregon State University biologist, found after studying white-tailed ptarmigans in a 10,000-acre area in central Colorado.

Yellowstone’s bison get a time limit

Yellowstone National Park’s long-awaited plan for managing its wandering bison herds hasn’t made everyone happy. The park’s final environmental impact statement, released in early September, tries to satisfy both bison advocates and the Montana Department of Livestock, which kills bison it fears could spread brucellosis to cattle. The park’s preferred alternative would allow a bigger […]
