  • Ocean channel in Bahamas marks genetic divide in Brazilian free-tailed bats
    on August 18, 2017 at 8:24 pm

    Brazilian free-tailed bats are expert flyers, capable of migrating hundreds of miles and regularly traveling more than 30 miles a night. But they pull up short at a narrow ocean channel that cuts across the Bahamas, dividing bat populations that last shared an ancestor hundreds of thousands of years ago. […]

  • Climate change and habitat conversion combine to homogenize nature
    on August 18, 2017 at 1:21 pm

    Climate change and habitat conversion to agriculture are working together to homogenize nature. In other words, the more things change, the more they are the same. […]

  • Popular sungazer lizards under threat from poaching
    on August 16, 2017 at 2:02 pm

    The sungazer (Smaug giganteus), a dragon-like lizard species endemic to the Highveld regions of South Africa, is facing an assault on two fronts as farming and industrialization encroaches on its natural habitat -- which already consist of only a several hundred square kilometers globally -- while the illegal global pet trade is adding pressure on pushing the species into extinction. […]

  • A decade of monitoring shows the dynamics of a conserved Atlantic tropical forest
    on August 16, 2017 at 2:02 pm

    Characterized with high levels of biodiversity and endemism, the Atlantic Tropical Forest has been facing serious anthropogenic threats over the last several decades. Having put important ecosystem services at risk, such activities need to be closely studied as part of the forest dynamics. Thus, a Brazilian team of researchers spent a decade monitoring a semi-deciduous forest located in an ecological park in Southeast Brazil. […]

  • Human intrusion on fruit bat habitats raises exposure risk to Hendra virus in Australia
    on August 15, 2017 at 1:51 pm

    There is a rising risk of human and domestic animal exposure to deadly Hendra virus (HeV) carried by fruit bats in Eastern Australia due to human intrusion into their habitats, human proximity to woodlands and vegetation loss, a new study reveals. […]

  • Tiny fraction of oceans could meet world's fish demand
    on August 14, 2017 at 4:53 pm

    Covering 70 percent of Earth's surface, the world's oceans are vast and deep. So vast, in fact, that nearly every coastal country has the potential to meet its own domestic seafood needs through aquaculture. In fact, each country could do so using a tiny fraction of its ocean territory. […]

  • Meadow of dancing brittle stars shows evolution at work
    on August 14, 2017 at 1:34 pm

    Newly-described fossil shows how brittle stars evolved in response to pressure from predators, and how an 'evolutionary hangover' managed to escape them. […]

  • Canary in a coal mine: Survey captures global picture of air pollution's effects on birds
    on August 11, 2017 at 4:48 pm

    Writing Aug. 11 in the journal Environmental Research Letters, University of Wisconsin-Madison Professor Tracey Holloway, an expert on air quality, and her former graduate student Olivia Sanderfoot sort through nearly 70 years of the scientific literature to assess the state of knowledge of how air pollution directly affects the health, well-being, reproductive success and diversity of birds.

    on August 10, 2017 at 2:48 pm

    The Australian Sunshine Coast's plant diversity has helped researchers confirm that nurture has the upper hand -- at least when it comes to plant microbes. A study of microbial communities necessary for plant development could improve crop and plant yields. […]

  • Yoda bat gets happy: New species officially recognized
    on August 10, 2017 at 2:48 pm

    An unusual breed of fruit bat -- previously nicknamed 'Yoda' due to its resemblance to the Star Wars Jedi Master -- has now officially been registered as a new species and renamed the happy (Hamamas) tube-nosed fruit bat. […]

  • Climate change: Silver fir beats Norway spruce and European beech
    on August 10, 2017 at 12:21 pm

    Climate change is making Swiss forests warmer and drier. The trees would have to adapt genetically to the rapidly changing climate to continue flourishing at their current growth location. Yet, they are unlikely to do so in such a short period of time – a single tree generation already takes 100 years or longer. Therefore, the question on how well adapted the trees already are today to the future climate will be crucial for the forests' future. […]

  • Ants dominate waste management in tropical rainforests
    on August 10, 2017 at 1:40 am

    A study has found that ants are responsible for moving more than half of food resources from the rainforest floor, playing a key role in maintaining a healthy ecosystem. […]

  • Salamanders that breed in the fall are less likely to disperse
    on August 9, 2017 at 7:14 pm

    With changing environments, pond-breeding salamanders face increasingly hazardous treks as the space between breeding ponds and their non-breeding habitat widens or is degraded. A study now suggests that a salamander's success may depend more on when it breeds than on the landscape obstacles it might face. Scientists believe that knowing the patterns in which salamanders move back and forth could lead to better forest management and conservation strategies. […]

  • The color of people's clothing affects lizard escape behavior
    on August 9, 2017 at 6:20 pm

    The color of T-shirts people wear affects escape behavior in western fence lizards, according to a new study. […]

  • First winged mammals from the Jurassic period discovered
    on August 9, 2017 at 6:03 pm

    Two 160-million-year-old mammal fossils discovered in China show that the forerunners of mammals in the Jurassic Period evolved to glide and live in trees. With long limbs, long hand and foot fingers, and wing-like membranes for tree-to-tree gliding, Maiopatagium furculiferum and Vilevolodon diplomylos are the oldest known gliders in the long history of early mammals. […]

  • Incomplete drought recovery may be the new normal
    on August 9, 2017 at 6:02 pm

    The amount of time it takes for an ecosystem to recover from a drought is an important measure of a drought's severity. During the 20th century, the total area of land affected by drought increased, and longer recovery times became more common, according to new research published by Nature by a group of scientists including Carnegie's Anna Michalak and Yuanyuan Fang. […]
