  • New research on avian response to wildfires
    on June 22, 2018 at 11:08 pm

    New research explores the effects fire has on ecosystems and the wildlife species that inhabit them. Scientists examined the impacts of fires of different severity levels on birds and how that changes as the time since fire increases. Scientists looked across 10 fires after they burned through forests in the Sierra Nevada. A key finding was that wildfire had strong, but varied, effects on the density of many of the bird species that were studied. […]

  • Zebrafish's near 360 degree UV-vision knocks stripes off Google Street View
    on June 21, 2018 at 6:11 pm

    A zebrafish view of the world has been forensically analyzed by researchers to reveal that how they see their surroundings changes hugely depending on what direction they are looking. […]

  • Fish's use of electricity might shed light on human illnesses
    on June 21, 2018 at 6:10 pm

    African weakly electric fish, commonly called baby whales, use incredibly brief electrical pulses to sense the world around them and communicate with other members of their species. Part of that electrical mechanism exists in humans -- and by studying these fish, scientists may unlock clues about conditions like epilepsy. […]

  • A mechanism behind choosing alcohol over healthy rewards is found
    on June 21, 2018 at 6:10 pm

    Changes in a brain signalling system contribute to the development of alcohol addiction-like behaviors in rats, according to a new study. The findings indicate a similar mechanism in humans. […]

  • Sticklebacks infected with parasites influence behavior of healthy fish
    on June 21, 2018 at 2:13 pm

    Certain types of tapeworm make sticklebacks behave carelessly and thus become easier prey for birds. A team of biologists have now demonstrated for the first time that the tapeworm not only influences the behavior of the infected fish -- indirectly, it can also induce risky behavior in other fish in the group. […]

  • Garden seed diet for threatened turtle doves has negative impact
    on June 21, 2018 at 2:13 pm

    New research into Britain's fastest declining bird species has found that young turtle doves raised on a diet of seeds foraged from non-cultivated arable plants rather than food provided in people's gardens are more likely to survive after fledging. Ecologists investigated the dietary habits of European turtle doves using DNA analysis of faecal samples and found significant associations between the body condition and the source of the bird's diet. […]

  • When cozying up with would-be predators, cleaner shrimp follow a dependable script
    on June 20, 2018 at 9:46 pm

    It's a mystery how cleaner shrimp partner with would-be fish predators -- sometimes even climbing in their mouths -- without getting eaten. A new study reveals how the shrimp convinces fish not to eat them, and the fish conveys that it's a friend and not a foe. […]

  • Neonics are being ingested by free-ranging animals
    on June 20, 2018 at 8:24 pm

    University of Guelph researchers found residues of the insecticides in the livers of wild turkeys, providing evidence that this common agrochemical is being ingested by free-ranging animals. […]

  • The sounds of climate change
    on June 20, 2018 at 7:02 pm

    Researchers describe a way to quickly sift through thousands of hours of field recordings to estimate when songbirds arrive at their Arctic breeding grounds. Their research could be applied to any dataset of animal vocalizations to understand how migratory animals are responding to climate change. […]

  • Gene-edited pigs are resistant to billion-dollar virus
    on June 20, 2018 at 7:01 pm

    Scientists have produced pigs that can resist one of the world's most costly animal diseases, by changing their genetic code. Tests with the virus -- called Porcine Reproductive and Respiratory Syndrome, or PRRS -- found the pigs do not become infected at all. The animals show no signs that the change in their DNA has had any other impact on their health or wellbeing. […]

  • T. Rex couldn't stick out its tongue
    on June 20, 2018 at 7:01 pm

    Dinosaurs are often depicted as fierce creatures, baring their teeth, with tongues wildly stretching from their mouths like giant, deranged lizards. But new research reveals a major problem with this classic image: Dinosaurs couldn't stick out their tongues like lizards. Instead, their tongues were probably rooted to the bottoms of their mouths in a manner akin to alligators. […]

  • People who feel threatened by vegetarianism more likely to care less about animals
    on June 20, 2018 at 4:59 pm

    New research suggests that if people perceive the rise of vegetarianism as a threat to their way of life they are more likely to care less for some animals. […]

  • Beluga whales have sensitive hearing, little age-related loss
    on June 20, 2018 at 2:06 pm

    Scientists published the first hearing tests on a wild population of healthy marine mammals. The tests on beluga whales in Bristol Bay, Alaska, revealed that the whales have sensitive hearing abilities and the number of animals that experienced extensive hearing losses was far less than what scientists had anticipated. […]

  • When you're a sitting duck, you learn to adapt
    on June 20, 2018 at 1:49 pm

    For common loons, black flies are a common blood-feeding pest and can cause nest abandonment and decreased fledging rates. A new study presents some of the best data to date supporting hypotheses about the effects that black flies have on common loon nesting behavior and success. […]

  • Birds have time-honored traditions, too
    on June 20, 2018 at 1:48 pm

    By faithfully copying the most popular songs, swamp sparrows create time-honored song traditions that can be just as long-lasting as human traditions, finds a new study. The results show that creating traditions that pass the test of time doesn't necessarily require exceptional smarts. […]

  • Do bats adapt to gates at abandoned mines?
    on June 20, 2018 at 1:47 pm

  • Light pollution a reason for insect decline
    on June 19, 2018 at 4:24 pm

    Climate change, pesticides and land use changes alone cannot fully explain the decline in insect populations in Germany. Scientists have now discovered that regions that have experienced a sharp decline in flying insects also have high levels of light pollution. Many studies already suggest that artificial light at night has negative impacts on insects, and scientists should pay greater attention to this factor when exploring the causes of insect population declines in the future. […]
