New research on avian response to wildfires Posted: 22 Jun 2018 04:08 PM PDT 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. |
Tiny jumping roundworm undergoes unusual sexual development Posted: 22 Jun 2018 02:48 PM PDT Biologists have shown that gonad development varies in other nematodes relative to C. elegans. Specifically, they focused on Steinernema carpocapsae, a nematode used in insect biocontrol applications in lawns and gardens. |
Biorenewable, biodegradable plastic alternative synthesized Posted: 22 Jun 2018 02:45 PM PDT Polymer chemists have taken another step toward a future of high-performance, biorenewable, biodegradable plastics. The team describes chemical synthesis of a polymer called bacterial poly(3-hydroxybutyrate) - or P3HB. The compound shows early promise as a substitute for petroleum plastics in major industrial uses. |
Starving fungi could save millions of lives each year Posted: 22 Jun 2018 07:46 AM PDT Researchers have identified a potentially new approach to treating lethal fungal infections that claim more than 1.6 million lives each year: starving the fungi of key nutrients, preventing their growth and spread. |
Wolf reintroduction: Yellowstone's 'landscape of fear' not so scary after all Posted: 22 Jun 2018 07:45 AM PDT 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. |
