  • Colombia peace deal brings new threat to country's rainforest
    on July 19, 2018 at 12:54 pm

    The historic peace treaty in Colombia which brought an end to half a century of violence has led to mass deforestation. Once FARC soldiers were disarmed, it led to a vacuum of power which is being exploited by large landowners who are now deforesting the area at an alarming rate to make way for farms and for the illegal growth of coca crops. An ecologically significant region of Colombia, is now at risk of disappearing. […]

  • For one tropical tree, effective seed dispersal relies especially on elephants
    on July 18, 2018 at 6:31 pm

  • Protecting tropical forest carbon stocks may not prevent large-scale species loss
    on July 16, 2018 at 8:45 pm

    As the world seeks to curb human-induced climate change, will protecting the carbon of tropical forests also ensure the survival of their species? A study suggests the answer to this question is far from straightforward. Forests with the greatest carbon content do not necessarily house the most species, meaning carbon-focused conservation can miss large swathes of tropical forest biodiversity. […]

  • Mangroves to mudflats and not back again
    on July 16, 2018 at 3:46 pm

    The long-term conversion of mangroves to mudflats can lead to destabilization of shorelines, negatively impacting their resilience to extreme weather events. […]

  • Particulate matter increases drought vulnerability of trees
    on July 16, 2018 at 2:35 pm

    Particulate matter deposits on leaves increase plant transpiration and the risk of plants suffering from drought. Particulate matter could thus be contributing more strongly to tree mortality and forest decline than previously assumed. This is suggested by results from a greenhouse study, in which tree seedlings grown in almost particulate matter free air or in unfiltered air were compared. […]
