  • New bird that humans drove to extinction discovered in Azores
    on July 26, 2017 at 3:09 pm

    Inside the crater of a volcano on Graciosa Island in the Azores archipelago, in the Atlantic Ocean, an international team of researchers has discovered the bones of a new extinct species of songbird, a bullfinch which they have named Pyrrhula crassa. The remains were found in a small cavity through which time ago the lava flowed. This bird disappeared a few hundreds of years ago due to human colonization of the islands and the introduction of invasive species. […]

  • How fear alone can cause animal extinction
    on July 25, 2017 at 4:22 pm

    Fear alone may contribute to the extinction of animal populations according to a recent study. When scientists exposed fruit flies to the scent of a praying mantis, a known predator, they found that the risk of extinction increased up to seven fold. The increased risk of extinction occurred because at small population sizes, as the flies spent more time being vigilant and less time eating, populations that declined could not quickly rebound. […]

  • 'Sound' research shows slower boats may cause manatees more harm than good
    on July 20, 2017 at 1:53 pm

    Slower boat speeds reduce risks to manatees. Or do they? Not exactly, according to new research. In fact, the very laws enacted to slow down boats in manatee habitats may actually be doing more harm than good. Slowing down boats makes it more difficult for manatees to detect and locate approaching boats. An innovative alerting device is proving to deliver a better solution. […]

  • Damming and lost connectivity for fish in Northeastern ecosystems
    on July 19, 2017 at 6:09 pm

    Fish that migrate between freshwater and sea ecosystems play a multitude of ecological roles. In the centuries since Europeans first colonized the Americas, damming and other disruptions to river connectivity have greatly decreased the migration opportunities of these species. A new article outlines the effects of lost habitat and river connectivity for these crucial fish. […]

  • Conserve intact forest landscapes to maximize biodiversity, reduce extinction risk
    on July 19, 2017 at 5:22 pm

  • Why Tyrannosaurus was a slow runner and why the largest are not always the fastest
    on July 17, 2017 at 3:56 pm

    No other animal on land is faster than a cheetah -- the elephant is indeed larger, but slower. For small to medium-sized animals, larger also means faster, but for really large animals, when it comes to speed, everything goes downhill again. For the first time, it is now possible to describe how this parabola-like relationship between body size and speed comes about. […]
