  • US and Canada have lost more than 1 in 4 birds in the past 50 years
    on September 19, 2019 at 6:23 pm

    Data show that since 1970, the US and Canada have lost nearly 3 billion birds, a massive reduction in abundance involving hundreds of species, from beloved backyard songbirds to long-distance migrants.

  • Division by subtraction: Extinction of large mammal species likely drove survivors apart
    on September 19, 2019 at 6:23 pm

    A new study suggests that the extinctions of mammoths, dire wolves and other large mammal species in North America drove surviving species to distance themselves from their neighbors, reducing interactions as predators and prey, territorial competitors or scavengers. The discovery could preview the ecological effects of future extinctions, the researchers say.

  • Wild animals' immune systems decline with age, sheep study finds
    on September 19, 2019 at 6:22 pm

    It is well established that weakened immune systems in old age affect people's health and fitness, but a study suggests that it is also an issue for wild animals.

  • European hedgehogs in Denmark carry a secret
    on September 19, 2019 at 4:25 pm

    Scientists have discovered, that Danish hedgehogs carry mecC-MRSA in their snouts.

  • Planned roads would be 'dagger in the heart' for Borneo's forests and wildlife
    on September 18, 2019 at 6:20 pm

    Malaysia's plans to create a Pan-Borneo Highway will severely degrade one of the world's most environmentally imperiled regions, says a research team.

  • Coastal birds can weather the storm, but not the sea
    on September 18, 2019 at 4:25 pm

    Coastal birds survive because their populations can absorb impacts and recover quickly from hurricanes -- even storms many times larger than anything previously observed.

  • Ecologists find strong evidence of fishing down the food web in freshwater lake
    on September 18, 2019 at 3:59 pm

    Research by ecologists shows strong evidence in a freshwater lake of 'fishing down the food web' - the deliberate shift away from top predatory fish on the food chain to smaller species closer to the base. While the effect has historically been observed almost exclusively in marine ecosystems and ocean fisheries, there has been little evidence of the effect in freshwater ecosystems.

  • Guppies teach us why evolution happens
    on September 18, 2019 at 11:57 am

    New study on guppies shows that animals evolve in response the the environment they create in the absence of predators, rather than in response to the risk of being eaten.

  • One of world's oldest bird species found in Waipara, New Zealand
    on September 17, 2019 at 11:36 pm

    The ancestor of some of the largest flying birds ever has been found in Waipara, New Zealand.

  • Understanding gaps in conservation data
    on September 17, 2019 at 8:01 pm

    A new study seeks to understand the type and magnitude of gaps in scientific information as a way to improve conservation planning.

  • Genomic migration analysis shows antibiotic resistance moving from humans to animals
    on September 17, 2019 at 5:30 pm

    New results show that human-acquired antibiotic resistance genes are being transmitted to livestock, companion animals and wildlife. Researchers analyzed a global set of 901 genome sequences of the bacteria Streptococcus agalactiae (aka group B Strep) from nine different host species -- humans, cows, dogs, fish, frogs, gray seals, dolphins, goats and a camel -- to better understand the transmission process. Streptococcus agalactiae can cause life-threatening illnesses.

  • How much of corals' nutrition comes from hunting?
    on September 17, 2019 at 3:54 pm

    When it comes to feeding, corals have a few tricks up their sleeve. Most of their nutrients come from microscopic algae living inside of them, but if those algae aren't creating enough sustenance, corals can use their tentacles to grab and eat tiny prey swimming nearby.

  • Not the hairstyle, but the content: Hair indicates whether wild animals were 'stressed'
    on September 17, 2019 at 2:45 pm

    Scientists have now demonstrated that the 'stress' hormone cortisol is deposited in hair of wild mongooses in Portugal and determined baselines for cortisol in these carnivores. It is now possible to investigate whether different habitats and changed living conditions, such as the return of the Iberian lynx, place a particular burden on the mongooses.

  • Victorian hog deer genetics revealed
    on September 17, 2019 at 2:04 pm

    Australian researchers looking for a genetic lifeline to endangered hog deer species endemic to Pakistan, northern India and mainland southeast Asia have found widespread hybridization of the species in Victoria.

  • Scientists identify previously unknown 'hybrid zone' between hummingbird species
    on September 17, 2019 at 11:58 am

    We usually think of a species as being reproductively isolated -- that is, not mating with other species in the wild. Occasionally, however, closely related species do interbreed. New research documents the existence of a previously undiscovered hybrid zone along the coasts of California and Oregon where two related bird hummingbirds are blurring species boundaries, and researchers hope that studying cases such as this one could improve their understanding of how biodiversity is created and maintained.

  • Elephant seal 'supermoms' produce most of the population, study finds
    on September 17, 2019 at 11:58 am

    Most of the pups born in an elephant seal colony in California over a span of five decades were produced by a relatively small number of long-lived 'supermoms,' according to a new study.

  • New species of giant salamander is world's biggest amphibian
    on September 17, 2019 at 1:25 am

    Using DNA from museum specimens collected in the early 20th century, researchers identified two new species of giant salamander -- one of which they suspect is the world's biggest amphibian.

  • Look out, invasive species: The robots are coming
    on September 16, 2019 at 3:40 pm

    Researchers published the first experiments to gauge whether biomimetic robotic fish can induce fear-related changes in mosquitofish, aiming to discover whether the highly invasive species might be controlled without toxicants or trapping methods harmful to wildlife. Their findings indicate that even brief exposure to a robotic replica of the mosquitofish's primary predator can provoke meaningful avoidance behaviors and physiological changes associated with the loss of energy reserves, potentially translating into lower rates of reproduction.

  • Antibiotic resistance surges in dolphins, mirroring humans
    on September 15, 2019 at 5:00 pm

    Scientists obtained a total of 733 pathogen isolates from 171 individual wild Bottlenose dolphins in Florida and found that the overall prevalence of resistance to at least one antibiotic for the 733 isolates was 88.2%. Resistance was highest to erythromycin, followed by ampicillin. It is likely that these isolates from dolphins originated from a source where antibiotics are regularly used, potentially entering the marine environment through human activities or discharges from terrestrial sources.

  • Male Trinidad guppies find food thanks to females
    on September 13, 2019 at 1:21 pm

    For male Trinidad Guppies applies: if you are hungry, seek female company. A recent study provides evidence that male guppy fish in the presence of females more often ended up at novel food patches. In contrast, female food discovery was independent of male presence.
