  • Mammals cannot evolve fast enough to escape current extinction crisis
    on October 15, 2018 at 7:44 pm

    The sixth mass extinction is underway, this time caused by humans. A team of researchers have calculated that species are dying out so quickly that nature's built-in defense mechanism, evolution, cannot keep up. If current conservation efforts are not improved, so many mammal species will become extinct during the next five decades that nature will need 3-5 million years to recover to current biodiversity levels. And that's a best-case scenario. […]

  • PPR virus poses threat to conservation
    on October 15, 2018 at 5:29 pm

    Researchers have reviewed the threat of the virus peste des petits ruminants (PPR) to conservation. […]

  • Crowd-sourced data wins protection for endangered tricolored blackbird
    on October 9, 2018 at 9:56 pm

    Researchers used eBird data to convince California to list the Tricolored Blackbird as endangered. […]

  • Polar bears gorged on whales to survive past warm periods; won't suffice as climate warms
    on October 9, 2018 at 9:56 pm

    A new study found that while dead whales are valuable sources of fat and protein for some polar bears, this resource will likely not be enough to sustain most bear populations in the future when the Arctic becomes ice-free in summers. […]

  • In the absence of bees, flies are responsible for pollination in the Arctic region
    on October 9, 2018 at 5:59 pm

    Most of the fauna in the Arctic region take part in pollinating, yet during the busiest flowering weeks, there's a shortage of such services. A recent study indicates that the pollination services provided to plants and, thus, the plants' ability to produce seeds are dependent on the timing of the blooming season, and on how many other species are in bloom simultaneously. […]

  • Underestimating combined threats of deforestation and wildlife trade will push Southeast Asian birds
    on October 7, 2018 at 12:40 pm

    The combined impact of deforestation and wildlife exploitation on bird numbers is severely underestimated and could lead to some species becoming extinct, a study has found. […]

  • Common genetic toolkit shapes horns in scarab beetles
    on October 4, 2018 at 6:39 pm

    Horns have evolved independently multiple times in scarab beetles, but distantly related species have made use of the same genetic toolkit to grow these prominent structures, according to a new study. […]

  • Species-rich forests store twice as much carbon as monocultures
    on October 4, 2018 at 6:39 pm

    Species-rich subtropical forests can take up on average twice as much carbon as monocultures. An international research team has evaluated data from forests grown specifically for this purpose in China with a total of over 150,000 trees. The results speak in favor of using many different tree species during reforestation. […]

  • 25 UK species' genomes sequenced for first time
    on October 3, 2018 at 11:39 pm

    The newly sequenced genomes will enable research into why some brown trout migrate to the open ocean, whilst others don't, or investigations into the magneto receptors in robins' eyes that allow them to 'see' the magnetic fields of the Earth. The genomes could also help to shed light on why red squirrels are vulnerable to the squirrel pox virus, yet grey squirrels can carry and spread the virus without becoming ill. […]

  • Tropical frogs found to coexist with deadly fungus
    on October 3, 2018 at 2:27 pm

    In 2004, the frogs of El Copé, Panama, began dying by the thousands. The culprit: the deadly chytrid fungus Batrachochytrium dendrobatidis. Within months, roughly half of native frog species there went locally extinct. A new study suggests that frogs remaining in El Copé developed the ability to coexist with chytrid fungus due to ecological and/or evolutionary changes. The results could mean good news for other areas hit hard by chytrid fungus. […]

  • Finding middle ground on the range
    on October 1, 2018 at 5:03 pm

    Cattle ranching and conservation may seem an unusual pair in the American West, but new research reveals a clear link between the economic health of ranches and the ability to maintain habitat for an iconic wild bird that for years has been at the center of public land policy debate: the greater sage grouse. […]

  • Decline in native fish species: Invasive species on the increase
    on October 1, 2018 at 3:43 pm

    The majority of Bavaria's watercourses are in poor ecological condition. A team has now conducted the first systematic analysis of long-term data on fish stocks in the Upper Danube, Elbe and Main rivers. The team concluded that native fish species are on the verge of extinction, while the populations of some invasive species are increasing. […]

  • Steelhead life cycle linked to environment, pink salmon abundance
    on September 28, 2018 at 5:13 pm

    A new study has found that steelhead trout have a remarkable life-cycle variation that responds to changes in temperature and numbers of other species of salmon. […]

  • Newly discovered hummingbird species already critically endangered
    on September 26, 2018 at 3:09 pm

    In 2017, researchers working in the Ecuadorian Andes stumbled across a previously unknown species of hummingbird -- but as documented in a new study, its small range, specialized habitat, and threats from human activity mean the newly described blue-throated hillstar is likely already critically endangered. […]

  • Invasive snakes 'hitchhiking' on planes
    on September 26, 2018 at 3:06 pm

    Scientists have discovered why brown tree snakes have become one of the most successful invasive species. The research team has been studying why a type of cat-eyed snake has been so effective at devastating native bird populations on the island of Guam. […]

  • World's largest ever bird has been named: Vorombe titan
    on September 26, 2018 at 12:27 pm

    After decades of conflicting evidence and numerous publications, scientists have finally put the 'world's largest bird' debate to rest. Vorombe titan (meaning 'big bird' in Malagasy and Greek), has taken the title reaching weights of up to 800 kg and three meters tall, with the research also discovering unexpected diversity in these Madagascan creatures. […]

  • How reliable are turtles for measuring ocean trash and marine health?
    on September 26, 2018 at 12:24 pm

    A meta-analysis of fifty years worth of sea turtle research reveals some important information about ocean trash, but important data is largely missing. […]

  • Climate change not main driver of amphibian decline
    on September 25, 2018 at 7:04 pm

    While a warming climate in recent decades may be a factor in the waning of some local populations of frogs, toads, newts and salamanders, it cannot explain the overall steep decline of amphibians, according to researchers. […]

  • Once majestic Atlantic Forest 'empty' after 500 years of over-exploitation
    on September 25, 2018 at 6:04 pm

    New research finds that 500 years of over-exploitation has halved mammal populations in South America's once majestic Atlantic Forest. A new analysis of mammal populations reveals the devastating effects of human disturbance since the area was first colonized in the 1500s. They found that apex predators and large carnivores, such as jaguars and pumas, as well as large-bodied herbivores, such as tapirs, were among the groups whose numbers had suffered the most. […]

  • Ancient mice discovered by climate cavers
    on September 24, 2018 at 10:50 pm

    The fossils of two extinct mice species have been discovered in caves in tropical Queensland by scientists tracking environment changes. […]
