New research on avian response to wildfires  

New research explores the effects fire has on ecosystems and the wildlife species that inhabit them. Scientists examined the impacts of fires of different severity levels on birds and how that changes as the time since fire increases. Scientists looked across 10 fires after they burned through forests in the Sierra Nevada. A key finding was that wildfire had strong, but varied, effects on the density of many of the bird species that were studied.

Wolf reintroduction: Yellowstone's 'landscape of fear' not so scary after all  

After wolves were reintroduced to Yellowstone National Park in the mid-1990s, some scientists thought the large predator reestablished a 'landscape of fear' that caused elk, the wolf's main prey, to avoid risky places where wolves killed them. But according to recent findings, Yellowstone's 'landscape of fear' is not as scary as first thought.
