  • Rise in oxygen levels links to ancient explosion of life, researchers find
    on November 20, 2017 at 4:13 pm

    Scientists have found that oxygen levels appear to increase by roughly 80 percent at about the same time as a three-fold increase in biodiversity during the Ordovician Period, between 445 and 485 million years ago. […]

  • European forests might not be realizing their full potential
    on November 17, 2017 at 1:58 pm

    European forest managers can have their cake and eat it, because according to a new study maximizing timber production in a forest does not necessarily have to come at a cost of reduced species diversity or the capacity to regulate climate change by the same forest. However most European forests fall well below their possible maximum levels of these three capacities. […]

  • Poison-ivy an unlikely hero in warding off exotic invaders?
    on November 13, 2017 at 5:36 pm

    The invasive Japanese knotweed causes much more severe damage to floodplain forests along the Susquehanna River, Pennsylvania, USA, than previously thought. Furthermore, the researchers point to a key role for the often-maligned poison-ivy as a native species that can not only compete with knotweed but also help sustain the growth of new trees. […]

  • Mapping functional diversity of forests with remote sensing
    on November 13, 2017 at 2:55 pm

    Productivity and stability of forest ecosystems strongly depend on the functional diversity of plant communities. Researchers have developed a new method to measure and map functional diversity of forests at different scales -- from individual trees to whole communities -- using remote sensing by aircraft. Their work paves the way for future airborne and satellite missions to monitor global plant functional diversity. […]

  • Bringing back large herbivores to the steppes
    on November 7, 2017 at 7:08 pm

    On 24th October 2017, the first group of nine kulan (Asiatic wild ass) was released into an acclimatization enclosure on the edge of the Altyn Dala protected area in central Kazakhstan. The animals had been transported 1200 km by helicopter from Altyn Emel National Park in the southeast of the country. They will be released in early spring. This is the first step in a multi-year project that aims to restore the full range of large herbivores to this unique area of steppe habitat. […]

  • Tiny bees play big part in secret sex lives of trees
    on November 6, 2017 at 8:22 pm

    When it comes to sex between plants, tiny bees the size of ladybugs play a critical role in promoting long-distance pairings. That's what scientists discovered after one of the most detailed paternity tests in wild trees ever conducted. The research gives new insights into how certain bees promote genetic diversity that is essential for plants to adapt to various threats, from disease to climate change. […]

  • Winners and losers of forest fragmentation
    on November 1, 2017 at 6:17 pm

    Breaking up the rainforest into small, isolated patches is forcing more species to live at the forest edge and putting those that are dependent on the forest core at risk. Eighty-five percent of species are now being impacted by this forest fragmentation. […]

  • Spooky conservation: Saving endangered species over our dead bodies
    on October 31, 2017 at 5:03 pm

    The secret to the survival of critically endangered wildlife could lie beyond the grave. A reseacher suggests revenue from human burials could fund nature reserves and parks for threatened species, effectively amounting to dead humans protecting living creatures. […]

  • Tropical forest reserves slow down global warming
    on October 27, 2017 at 1:44 pm

    National parks and nature reserves in South America, Africa and Asia, created to protect wildlife, heritage sites and the territory of indigenous people, are reducing carbon emissions from tropical deforestation by a third, and so are slowing the rate of global warming, a new study shows. […]

  • Peatland plants adapting well to climate change
    on October 27, 2017 at 12:55 pm

    They account for just three per cent of the Earth's surface but play a major role in offsetting carbon dioxide emissions -- and now a team of scientists has discovered that the plants that make up peat bogs adapt exceptionally well to climate change. […]

  • How harmful are nano-copper and anti-fungal combinations in the waterways?
    on October 26, 2017 at 5:53 pm

    A new study explores the risks to the smallest creatures in aquatic communities posed by increased use of the anti-fouling wood treatment. […]

  • Investing in conservation pays off, study finds
    on October 25, 2017 at 6:11 pm

    Governments and donors have spent billions of dollars since the 1992 Rio Earth Summit attempting to slow the pace of species extinctions around the world. Now, a new article provides the first clear evidence that those efforts are working. […]

  • Deforestation linked to palm oil production is making Indonesia warmer, study finds
    on October 25, 2017 at 1:05 pm

    In the past decades, large areas of forest in Sumatra, Indonesia, have been replaced by cash crops like oil palm and rubber plantations. New research shows that these changes in land use increase temperatures in the region. The added warming could affect plants and animals and make parts of the country more vulnerable to wildfires. […]

  • Shallow soils promote savannas in South America
    on October 23, 2017 at 10:07 pm

    The boundary between South American tropical rainforests and savannas is influenced by the depth to which plants can root, research indicates. Shallow rooting depth promotes the establishment of savannas. Previous research has shown that precipitation and fire mediate tropical forest and savanna distributions. The study shows that below ground conditions need to be considered to understand the distribution of terrestrial vegetation both historically and in the face of future climate change. The study is based on computer vegetation models. […]

  • Fruit-eating increases biodiversity
    on October 23, 2017 at 7:05 pm

    By dispersing the seeds of plants, fruit-eating animals contribute to the possibility of increased plant speciation and thus biodiversity, investigators have discovered. […]

  • Rethinking well-being and sustainability measurements from local to global scales
    on October 23, 2017 at 5:20 pm

    A new study suggests that standard ways of measuring well-being and sustainability in communities used by global organizations may be missing critical information and could lead to missteps in management actions. The article suggests alternative and complementary approaches that use indicators grounded in the values of a particular community. […]

  • Reduced impact logging still harms biodiversity in tropical rainforests
    on October 23, 2017 at 4:35 pm

    Even low levels of logging in the Amazon rainforest may lead to great losses in biodiversity, new research has found. The research looked at 34 different plots in the state of Pará -- a focal point for Amazon protection efforts in the last decades. They found that even low levels of logging leaded to negative effects on dung beetle diversity and rates of dung beetle-mediated […]
