  • Chimpanzees at the crossroads: Adapt to living outside protected areas
    on May 22, 2019 at 4:05 pm

    Research carried out into the impact of changes to chimpanzee habitats found they have adapted to human developments in a number of ways -- including learning how to cross roads safely and the best times to visit human habitats -- but their survival is still threatened. […]

  • Extreme draining of reservoir aids young salmon and eliminates invasive fish
    on May 21, 2019 at 8:24 pm

    A new study finds that the low-cost, extreme draining of a reservoir in Oregon aided downstream migration of juvenile chinook salmon -- and led to the gradual disappearance of two species of predatory invasive fish in the artificial lake. […]

  • Baby tiger sharks eat songbirds
    on May 21, 2019 at 4:45 pm

    Tiger sharks have a reputation for being the 'garbage cans of the sea' -- they'll eat just about anything, from dolphins and sea turtles to rubber tires. And in a new study, scientists just discovered that baby tiger sharks eat birds. And not seabirds like gulls or pelicans -- familiar backyard birds like sparrows, woodpeckers, and doves. In short: Baby sharks, doo doo doo doo doo doo They eat birds, doo doo doo doo doo doo […]

  • Penguins and their chicks' responses to local fish numbers informs marine conservation
    on May 21, 2019 at 11:51 am

    Endangered penguins respond rapidly to changes in local fish numbers, and monitoring them could inform fisheries management and marine conservation. […]

  • Scientists propose rethinking 'endangered species' definition to save slow-breeding giants
    on May 17, 2019 at 12:16 pm

    Conservation decisions based on population counts may fail to protect large, slow-breeding animals from irrevocable decline, according to new research. […]

  • Protecting rare species can benefit human life
    on May 16, 2019 at 7:53 pm

    Preserving rare species for the sake of global biodiversity has long been the primary focus for conservationists. To better protect rare animals, insects and plants, and to prepare for an uncertain future influenced by climate change, a team of researchers is aiming to merge this conventional wisdom with a new way of thinking: arguing researchers needs to better understand how rare species benefit people outside of their existence value. […]

  • Organic animal farms benefit birds nesting in agricultural environments
    on May 16, 2019 at 2:14 pm

    Environmental subsidies for agriculture awarded by the European Union aim to improve biodiversity in agricultural environments. A recently completed Finnish study indicates that the proximity of organic animal farms increases bird numbers, and this has enabled environmental subsidies to positively impact bird populations. […]

  • As bumblebee diets narrow, ours could too
    on May 15, 2019 at 5:02 pm

    A new study reveals the loss of plant diversity harms the humble bumblebee at a critical stage in its development from egg to adult. […]

  • Escaped pet parrots are now naturalized in 23 US states, study finds
    on May 14, 2019 at 8:22 pm

    Research data on bird sightings finds that 56 different parrot species have been spotted in 43 states, and 25 of those species are now breeding in the wild in 23 different states. […]

  • Antarctic biodiversity hotspots exist wherever penguins and seals poop
    on May 9, 2019 at 6:28 pm

    Scientists have found that on the desolate Antarctic peninsula, nitrogen-rich poop from colonies of penguins and seals enriches the soil so well that it helps create biodiversity hotspots throughout the region. […]

  • How sea level rise affects birds in coastal forests
    on May 9, 2019 at 6:28 pm

    Saltwater intrusion changes coastal vegetation that provides bird habitat. Researchers found that the transition from forests to marshes along the North Carolina coast due to climate change could benefit some bird species of concern for conservation. […]

  • Birds outside their comfort zone are more vulnerable to deforestation
    on May 9, 2019 at 2:18 pm

    Members of the same bird species can have dramatically different responses to deforestation depending on where they live, finds a new study. […]

  • Are otters threatening amphibian populations?
    on May 9, 2019 at 12:00 pm

    The Eurasian otter typically eats fish, but amphibians, which are in global decline, are also part of its diet, especially when fish are scarce. Researchers identified bones of amphibians in otter feces from southern Italy to determine which types of amphibians are typically eaten. They also reviewed 64 studies of otter diet. […]

  • Threatened sturgeon learns for the fitness
    on May 7, 2019 at 4:14 pm

    An international team is providing one of the first proofs of the complex learning behavior of fish in a recent study. The Atlantic sturgeon is thought to be locally extinct in Germany. Scientists are working toward sturgeon reintroduction and are investigating whether sturgeon training can increase their fitness for the wild. An important fitness factor is their feeding behavior. A two-week 'learning lead' made the search for food more efficient. […]

  • Even more amphibians are endangered than we thought
    on May 6, 2019 at 4:41 pm

    Due to a lack of data on many amphibian species, only about 44 percent of amphibians have up-to-date assessments on their risk of extinction, compared to nearly 100% of both birds and mammals. Now, researchers have used known ecological, geographical, and evolutionary attributes of these data-deficient species to model their extinction risk -- and their assessment suggests that at least 1,000 more species are threatened than was previously believed. […]

  • Hunting jeopardizes forest carbon storage, yet is overlooked in climate mitigation efforts
    on May 6, 2019 at 2:54 pm

    The loss of animals, often due to unregulated or illegal hunting, has consequences for the carbon storage capacity of forests, yet this link is rarely mentioned in high-level climate policy discussions, according to a new study. […]

  • Cattle ranching could help conserve rare African antelope, lions
    on May 3, 2019 at 5:13 pm

    Ranch managers' placement of cattle corrals away from Jackson's hartebeest likely would allow the antelope species to increase, with lions focused on the zebras that congregate at the resulting glades in central Kenya. […]

  • Giant panda's bamboo diet still looks surprisingly carnivorous
    on May 2, 2019 at 3:10 pm

    Giant pandas are unusual in being extremely specialized herbivores that feed almost exclusively on highly fibrous bamboo, despite belonging to a clade (Carnivora) of primarily flesh-eating carnivores. But a study suggests that the switch to a restricted vegetarian diet wasn't, in some respects, as big an evolutionary leap as it seems. […]

  • New scat study provides clues to puzzling existence of Humboldt martens in Oregon Dunes National Recreation Area
    on May 1, 2019 at 7:33 pm

    With a new scat study, researchers are chipping away at solving a biological mystery on the central Oregon coast: the existence of an isolated population of a small but fierce forest predator that makes its home in the Oregon Dunes National Recreation Area. […]

  • For certain invasive species, catching infestation early pays off
    on April 29, 2019 at 10:28 pm

    Researchers have conducted a global meta-analysis of the characteristics and size of invasive alien species' impacts on native species as invaders become more abundant. […]
