  • Ozark grasslands experience major increase in trees and shrubs
    on September 21, 2017 at 8:12 pm

    Woody vegetation, such as trees and shrubs, has increased dramatically in Ozark grasslands over the past 75 years, according to a study. If these ecosystems continue to favor woody vegetation, will it be possible to maintain open grasslands for the foreseeable future? […]

    on September 20, 2017 at 10:21 pm

    A new study of the world's seven sea turtle species provides evidence that their numbers are growing overall (unlike many endangered vertebrates), thanks to years of conservation efforts that have played a key role in sea turtle recovery -- even for small sea turtle populations. […]

  • When residents take charge of their rainforests, fewer trees die
    on September 20, 2017 at 10:21 pm

    When the government gives citizens a personal stake in forested land, trees don't disappear as quickly and environmental harm slows down, research finds. […]

  • Animal acoustic activity decline shows forest fire pollution wreaks havoc on wildlife
    on September 20, 2017 at 5:17 pm

    Forest fires in Southeast Asia during the El Niño droughts of 2015 caused considerable disruption to the biodiversity of the region due to the smoke-induced 'haze' they created, according to new research. […]

  • A cereal crop survives heat and drought
    on September 18, 2017 at 6:30 pm

    Scientists have published the genome sequence of Pearl millet, a drought resistant crop plant most important in arid regions in Africa and Asia. This plant is important to small and medium farmers who grow the plant without larger irrigation. Pearl millet delivers a good harvest index under drought and heat conditions when rice, maize or wheat already have no grains anymore. […]

  • Old fish few and far between under fishing pressure
    on September 14, 2017 at 7:23 pm

    A new study has found that, for dozens of fish populations around the globe, old fish are greatly depleted -- mainly because of fishing pressure. Old fish are increasingly missing in many populations around the world. […]

  • Light at the end of the tunnel: Restored forest now shelters dozens of endangered species
    on September 14, 2017 at 7:22 pm

    A twenty-year effort to protect and manage tiny remnants of a dilapidated forest in Benin, along with its agricultural and fallow vegetation surroundings, resulted in 14 ha of rich secondary forest, which corresponds to the size of nearly 20 sacred groves. This sanctuary now protects the critically endangered red-bellied monkey together with 52 endangered plant species. […]

    New research shows, in contrast to expectations, 'the rapid global range expansion of true frogs was not associated with increased net-diversification.' […]

  • Coffee and bees: New model of climate change effects
    on September 12, 2017 at 2:28 pm

    Areas in Latin America suitable for growing coffee face predicted declines of 73-88 percent by 2050. But bee species diversity may save the day, even if many species in cool highland regions are lost as the climate warms. […]

  • 'Keep it local' approach more effective than government schemes at protecting rainforest
    on September 12, 2017 at 1:31 pm

    Conservation initiatives led by local and indigenous groups can be just as effective as schemes led by government, according to new research. In some cases in the Amazon rainforest, grassroots initiatives can be even more effective at protecting this vital ecosystem. […]

  • Cold region 'tipping point' now inevitable
    on September 11, 2017 at 4:26 pm

    The decline of cold regions called periglacial zones is now inevitable due to climate change, researchers say. […]

  • Biodiversity just as powerful as climate change for healthy ecosystems
    on September 11, 2017 at 4:26 pm

    Biodiversity is proving to be one of humanity's best defenses against extreme weather. In past experiments, diversity has fostered healthier, more productive ecosystems, like shoreline vegetation that guards against hurricanes. However, many experts doubted whether these experiments would hold up in the real world. A study offers a decisive answer: biodiversity's power in the wild surpasses experimental predictions, in some cases topping even effects of climate. […]

  • Eighteenth century nautical charts reveal coral loss
    on September 7, 2017 at 6:27 pm

    Centuries-old nautical charts, mapped by long-deceased sailors to avoid shipwrecks, have been used by modern scientists to study loss of coral reefs. A new study compared early British charts to modern coral habitat maps to understand changes to reef environments. […]

  • The sand trap: Demand outpaces caution, knowledge
    on September 7, 2017 at 6:27 pm

    Sand, spanning miles of beaches, carpeting vast oceans and deserts, is a visual metaphor for limitless resources. Yet seize another metaphor -- sand in an hourglass, marking time running out. […]

  • Courts' critical, underappreciated role in climate policy
    on September 7, 2017 at 6:26 pm

  • Increasing effective decision-making for coastal marine ecosystems
    on September 7, 2017 at 2:23 pm

    Marine restoration, rather than protection, might be the most cost-effective solution for coastal marine ecosystems suffering from human activities, a new study has found. The study examined how to best benefit coastal marine ecosystems on limited conservation budgets, to help managers better understand the trade-offs. […]

  • Warmer world may bring more local, less global, temperature variability
    on September 5, 2017 at 4:32 pm

    Many tropical or subtropical regions could see increases in naturally occurring temperature variability as Earth warms over coming decades, a new study suggests. These local changes could occur even though Earth's global mean surface temperature variability will likely decrease because of less solar reflection from icecaps at high latitudes. […]

  • Diverse landscapes are more productive and adapt better to climate change
    on September 4, 2017 at 8:56 pm

    Ecosystems with high biodiversity are more productive and stable towards annual fluctuations in environmental conditions than those with a low diversity of species. They also adapt better to climate-driven environmental changes. These are the key findings environmental scientists made in a study of about 450 landscapes harboring 2,200 plants and animal species. […]
