  • In a warming climate, Arctic geese are rushing north
    on July 19, 2018 at 6:21 pm

    As Arctic temperatures continue to rise, migratory barnacle geese have responded by speeding up their 3,000-kilometer migration in order to reach their destination more quickly with fewer stops along the way, according to new evidence. Unfortunately, the birds' earlier arrival isn't making as much of a difference as one might expect. […]

    on July 19, 2018 at 3:22 pm

    A new study has proposed an ecological threshold concentration of 9 metals for 10 taxa of aquatic macroinvertebrates from clean sites in the Nalón river basin (Asturias). This is the first step towards incorporating into river management plans quality criteria relating to the bioaccumulation of hazardous substances, as required by the EU. […]

    on July 17, 2018 at 6:25 pm

    New research demonstrates dramatic positive benefits for native trees following rat removal at Palmyra Atoll, a magnificent National Wildlife Refuge and natural research laboratory located about 1000 miles south of Hawaii. For five native tree species, including Pisonia grandis, fewer than 150 seedlings were counted in the presence of rats, and more than 7700 seedlings were counted five years after rats were removed. […]

  • Social isolation: Animals that break away from the pack can influence evolution
    on July 17, 2018 at 3:25 pm

    For some animals -- such as beetles, ants, toads, and primates -- short-term social isolation can be just as vital as social interaction to development and long-term evolution. Evolutionary biologists describe approaches for testing how an animal's isolation might impact natural selection and evolution. This framework can help design more effective breeding, reintroduction, and conservation strategies. […]

  • The ancient armor of fish -- scales -- provide clues to hair, feather development
    on July 17, 2018 at 1:47 pm

    How do scale patterns on fish provide understanding of the development of feathers, fur -- and even cancer? Biologists are investigating. […]

  • Variations of a single gene drive diverse pigeon feather patterns
    on July 17, 2018 at 1:47 pm

    Biologists have discovered that different versions of a single gene, called NDP (Norrie Disease Protein), have unexpected links between color patterns in pigeons, and vision defects in humans. These gene variations were likely bred into pigeons by humans from a different pigeon species and are now evolutionarily advantageous in wild populations of feral pigeons living in urban environments. […]

  • Friendlier fish may be quicker to take the bait
    on July 16, 2018 at 3:45 pm

    The bluegill on your dinner plate might have been more social than the rest of its group, according to a new study, and its removal from the lake could mean major changes for the remaining population. […]

  • Australia has a new venomous snake -- And it may already be threatened
    on July 16, 2018 at 2:35 pm

    The ink has not yet dried on a scientific paper describing a new species of snake, yet the reptile may already be in danger of extinction due to mining. A team of biologists discovered a new species of bandy-bandy snake at Weipa on the west coast of the Cape York Peninsula. […]

  • Ant soldiers don't need big brains
    on July 13, 2018 at 12:44 am

    Army ant (Eciton) soldiers are bigger but do not have larger brains than other workers within the same colony that fulfill more complex tasks, according to a new study. A collaborative team of researchers suggests that because the very specific and limited tasks soldiers fulfill place limited cognitive demands on them, investment in the development of brain tissue is also limited. […]

  • Rats trail behind shrews, monkeys, and humans in visual problem solving
    on July 12, 2018 at 9:22 pm

    Rats take a fundamentally different approach toward solving a simple visual discrimination task than tree shrews, monkeys, and humans, according to a comparative study of the four mammal species. The work could have important implications for the translation of research in animal models to humans. […]

  • Fuzzy yellow bats reveal evolutionary relationships in Kenya
    on July 12, 2018 at 9:22 pm

    DNA analysis of fuzzy yellow bats in Kenya revealed at least two new species unknown to science. It's important because Africa's biodiversity is often under-studied and poorly understood, even though bats play a crucial role in agriculture and public health. […]

  • Financial incentives create critical waterbird habitat in extreme drought
    on July 12, 2018 at 9:22 pm

    New research shows how financial incentive programs can create vital habitat for waterbirds, filling a critical need in drought years. Researchers used satellite images to evaluate two issues: 1) the impact of the 2013-2015 drought on waterbird habitat in the Central Valley; and, 2) the amount of habitat created by incentive programs. […]

  • Understanding the social dynamics that cause cooperation to thrive, or fail
    on July 12, 2018 at 6:34 pm

    Biologists address the question of how an evolving social network influences the likelihood of cooperation in a theoretical social group. They find that, although networks where connected individuals are closely related are more likely to cooperate, such groups can trigger a feedback loop that alters the structure of the network and leads to cooperation's collapse. […]

  • Parental chromosomes kept apart during embryo's first division
    on July 12, 2018 at 6:16 pm

    It was long thought that during an embryo's first cell division, one spindle is responsible for segregating the embryo's chromosomes into two cells. Scientists now show that there are actually two spindles, one for each set of parental chromosomes, meaning that the genetic information from each parent is kept apart throughout the first division. […]

  • Tree shrews can tolerate hot peppers: Mutation in pain receptor makes peppery plant palatable
    on July 12, 2018 at 6:16 pm

    Almost all mammals avoid eating chili peppers and other 'hot' foods, because of the pain they induce. But not the tree shrew, according to a new study. The researchers found that this close relative of primates is unaffected by the active ingredient in chili peppers due to a subtle mutation in the receptor that detects it. […]

  • New evidence of two subspecies of American pikas in Rocky Mountain National Park
    on July 12, 2018 at 4:39 pm

    Rocky Mountain National Park provides habitat for not one, but two subspecies of the American pika. […]

  • Imaging technique illuminates immune status of monkeys with HIV-like virus
    on July 12, 2018 at 3:44 pm

    Findings from an animal study suggest that a non-invasive imaging technique could, with further development, become a tool to assess immune system recovery in people receiving treatment for HIV infection. Researchers used single-photon emission computed tomography (SPECT) and a CD4-specific imaging probe to assess immune system changes throughout the bodies of macaques infected with SIV following initiation and interruption of antiretroviral therapy (ART). They evaluated pools of CD4+ T cells in tissues. […]
