  • Massive organism is crashing on our watch
    on October 17, 2018 at 6:10 pm

    Researchers have conducted the first complete assessment of the Pando aspen clone and the results show continuing deterioration of this 'forest of one tree.' While a portion of the famed grove is recovery nicely as a result of previous restoration, the majority of Pando (Latin for 'I Spread') is diminishing by attrition. […]

  • Forest carbon stocks have been overestimated for 50 years
    on October 16, 2018 at 3:01 pm

    A formula used to calculate basic wood density has recently been corrected. Basic density is widely used to compute carbon storage by trees. Researchers estimate that the error in the initial formula resulted in an overestimation of forest carbon stocks, to the tune of almost 5 percent. […]

  • Why tropical forests are so ecologically diverse
    on October 15, 2018 at 8:42 pm

    The population of a tropical tree increases mostly in places where it is rare, a new study found. […]

  • Mammals cannot evolve fast enough to escape current extinction crisis
    on October 15, 2018 at 7:44 pm

    The sixth mass extinction is underway, this time caused by humans. A team of researchers have calculated that species are dying out so quickly that nature's built-in defense mechanism, evolution, cannot keep up. If current conservation efforts are not improved, so many mammal species will become extinct during the next five decades that nature will need 3-5 million years to recover to current biodiversity levels. And that's a best-case scenario. […]

  • Oldest fossil of a flying squirrel sheds new light on its evolutionary tree
    on October 9, 2018 at 3:50 pm

    The oldest flying squirrel fossil ever found has unearthed new insight on the origin and evolution of these airborne animals. […]

  • Newly discovered moth named Icarus sports a flame-shaped mark and prefers high elevations
    on October 9, 2018 at 3:36 pm

    A new species of owlet moth recently discovered to inhabit high-elevation mountains in western North America has been named after the Greek mythological character Icarus. […]

  • Underestimating combined threats of deforestation and wildlife trade will push Southeast Asian birds
    on October 7, 2018 at 12:40 pm

    The combined impact of deforestation and wildlife exploitation on bird numbers is severely underestimated and could lead to some species becoming extinct, a study has found. […]

  • Species-rich forests store twice as much carbon as monocultures
    on October 4, 2018 at 6:39 pm

    Species-rich subtropical forests can take up on average twice as much carbon as monocultures. An international research team has evaluated data from forests grown specifically for this purpose in China with a total of over 150,000 trees. The results speak in favor of using many different tree species during reforestation. […]

  • Genome of Japanese insect delicacy sheds light on history of Earth
    on October 4, 2018 at 3:01 pm

    Scientists have shed light on the evolutionary biology and distribution of Stenopsyche caddisflies, a common insect in Japanese rivers and a local delicacy. The discovery also identified new genetic lineages among previously recognized species. […]

  • Primary tropical forests are best but regrowing forests are also vital to biodiversity
    on October 4, 2018 at 12:53 pm

    Even after 40 years of recovery, secondary forests remain species and carbon-poor compared to undisturbed primary forests, a new study reveals. However these secondary forests -- forests regrowing in previously deforested areas -- are still vitally important to biodiversity conservation and carbon storage, argue scientists. […]

  • 25 UK species' genomes sequenced for first time
    on October 3, 2018 at 11:39 pm

    The newly sequenced genomes will enable research into why some brown trout migrate to the open ocean, whilst others don't, or investigations into the magneto receptors in robins' eyes that allow them to 'see' the magnetic fields of the Earth. The genomes could also help to shed light on why red squirrels are vulnerable to the squirrel pox virus, yet grey squirrels can carry and spread the virus without becoming ill. […]

  • Green algae, white noise: Gas bubbles produced during photosynthesis 'ring' upon release
    on October 3, 2018 at 6:29 pm

    Gas bubbles released by marine algae during photosynthesis produce sound whose intensity correlates with the degree of algal cover on coral reefs, according to a new study. […]

  • Complex factors can drive the emergence and evolution of plant pathogens
    on October 3, 2018 at 2:27 pm

    New research sheds light on factors that contribute to the rise and spread of plant diseases. […]

  • Set in amber, fossil ants help reconstruct evolution of fungus farming
    on October 1, 2018 at 7:40 pm

    A new study makes it clear that the constant threat of crop parasites repeatedly pushed evolution in strikingly similar directions in ants, creating structures that helped the ants reinforce their partnership with bacteria. […]

  • Decline in native fish species: Invasive species on the increase
    on October 1, 2018 at 3:43 pm

    The majority of Bavaria's watercourses are in poor ecological condition. A team has now conducted the first systematic analysis of long-term data on fish stocks in the Upper Danube, Elbe and Main rivers. The team concluded that native fish species are on the verge of extinction, while the populations of some invasive species are increasing. […]

  • Where did broadleaved evergreen trees survive during the last glacial period in Japan?
    on October 1, 2018 at 2:19 pm

    Scientists have modeled the phylogeographic relationships and demographic changes of Castanopsis sieboldii, which is a dominant tree of the broadleaved evergreen forests of Japan, dating back to about 100,000 years ago. The model strongly suggested that C. sieboldii survived in at least 4 areas through the last glacial maximum (LGM). The results present new evidence concerning conservation of genetic diversity of C. sieboldii. […]

  • Invasive plants can boost blue carbon storage
    on October 1, 2018 at 12:21 pm

    When invasive species enter the picture, things are rarely black and white. A new article has revealed that some plant invaders could help fight climate change by making it easier for ecosystems to store 'blue carbon' -- the carbon stored in coastal environments like salt marshes, mangroves and seagrasses. But other invaders, most notably animals, can do the exact opposite. […]

  • New invasive bryozoan arrives in Alaskan waters
    on September 28, 2018 at 1:57 am

    Alaska has a near-pristine marine ecosystem--it has fewer invasive species in its waters than almost any other state in the U.S. But that could be changing. With help from local volunteers, biologists at the Smithsonian Environmental Research Center (SERC) and Temple University have reported a new invasive species in the Ketchikan region, the invertebrate filter-feeder Bugula neritina, and documented the continuing spread of three other non-native species. […]

  • Tiger mosquitoes are capable of transmitting yellow fever
    on September 26, 2018 at 3:08 pm

    Since December 2016, Brazil has been grappling with its worst yellow fever outbreak for several decades. Research has now demonstrated that the yellow fever virus can be transmitted via Aedes albopictus, the tiger mosquito. This opportunistic species is capable of colonizing both urban and forest areas. […]

  • Invasive snakes 'hitchhiking' on planes
    on September 26, 2018 at 3:06 pm

    Scientists have discovered why brown tree snakes have become one of the most successful invasive species. The research team has been studying why a type of cat-eyed snake has been so effective at devastating native bird populations on the island of Guam. […]
