  • Penned release of green geckos has potential to help preserve threatened native species
    on January 14, 2021 at 2:58 pm

    Researchers outlined how they translocated 19 barking geckos to Mana Island, using the method of penned release – enclosing them in a 100m² pen for three months so they get used to the site and hopefully establish a breeding population.

  • Bees respond to wildfire aftermath by producing more female offspring
    on January 14, 2021 at 1:54 pm

    Researchers have found that the blue orchard bee, an important native pollinator, produces female offspring at higher rates in the aftermath of wildfire in forests.

  • Asian butterfly mimics other species to defend against predators
    on January 13, 2021 at 5:07 pm

    Many animal and insect species use Batesian mimicry — mimicking a poisonous species — as a defense against predators. The common palmfly Elymnias hypermnestra — a species of satyrine butterfly that is found throughout wide areas of tropical and subtropical Asia — adds a twist to this evolutionary strategy.

  • DNA in water used to uncover genes of invasive fish
    on January 12, 2021 at 7:48 pm

    In a proof-of-principle study, researchers describe a new technique in which they analyzed environmental DNA – or eDNA – from water samples in Cayuga Lake to gather nuanced information about the presence of these invasive fish.

  • Study of flowers with two types of anthers solves mystery that baffled Darwin
    on January 12, 2021 at 5:52 pm

    Most flowering plants depend on pollinators such as bees to transfer pollen from the male anthers of one flower to the female stigma of another flower, enabling fertilization and the production of fruits and seeds. Bee pollination, however, involves an inherent conflict of interest, because bees are only interested in pollen as a food source. A new study describes a pollination strategy involving flowers with two distinct sets of anthers that differ in color, size, and position.

  • Tiny bubbles tell tales of big volcanic eruptions
    on January 19, 2021 at 5:20 pm

    Microscopic bubbles can tell stories about Earth’s biggest volcanic eruptions and geoscientists have discovered some of those stories are written in nanoparticles.

  • Acidification impedes shell development of plankton off the U.S. West Coast, study shows
    on January 19, 2021 at 5:20 pm

    Results from a 2016 research cruise show ocean acidification has interfered with shell development of zooplankton that are a critical part of the marine food web.

  • New clues help explain why PFAS chemicals resist remediation
    on January 19, 2021 at 5:20 pm

    Chemicals used in firefighting foam and other products can last for decades in the environment, resisting efforts to remove them. New research suggest why that happens and new avenues for remediation.

  • New tool removes chemotherapy drugs from water systems
    on January 19, 2021 at 1:52 pm

    ‘What goes in, must come out’ is a familiar refrain. It is especially pertinent to the challenges facing researchers who are investigating methods to remove chemicals and pharmaceuticals from public water systems. Cleaning products, organic dyes and pharmaceuticals are finding their ways into water bodies with wide-ranging negative implications to health and the environment, a mechanical engineer explains.

  • Climate change will alter the position of the Earth’s tropical rain belt
    on January 18, 2021 at 4:31 pm

    Researchers describe future changes to the tropical rain belt with expected climate change. The changes will cause droughts in large sections of the globe, threatening biodiversity and food security.

  • Extreme fire weather
    on January 14, 2021 at 11:06 pm

    When the Thomas Fire raged through Ventura and Santa Barbara counties in December 2017, an earth science researcher was stunned by its severity. Burning for more than a month and scorching 440 square miles, the fire was then considered the worst in California’s history.

  • Bees respond to wildfire aftermath by producing more female offspring

  • Wildfire smoke is more cooling on climate than computer models assume
    on January 12, 2021 at 9:36 pm

    Many of the most advanced climate models simulate smoke that is darker, or more light absorbing, than what researchers see in observations.

  • Identifying where to reforest after wildfire
    on December 18, 2020 at 9:51 pm

    Forest managers can now look to a newly enhanced, predictive mapping tool to learn where forests are likely to regenerate on their own and where replanting efforts may be beneficial. This study also indicates a not-so-evergreen future of fewer conifers.

  • Fire-resistant tropical forest on brink of disappearance
    on December 18, 2020 at 1:41 pm

    A new study reveals the extreme scale of loss and fragmentation of tropical forests, which once covered much of the Indonesian islands of Sumatra and Kalimantan. The study also reveals that only 10 percent of the forest that is left remains fire-resistant. The researchers warn that protecting this is crucial for preventing catastrophic fire.
