  • Why nature restoration takes time
    on February 8, 2017 at 2:41 pm

    'Relationships' in the soil become stronger during nature restoration. Although all major groups of soil life are already present in former agricultural soils, they are not really 'connected'. These connections need time to (literally) grow, and fungi are the star performers. A European research team has shown the complete network of soil life for the first time. […]

  • More frequent, more intense and longer-lasting storms cause heavier spring rain in central US
    on December 1, 2016 at 9:48 pm

    Intense storms have become more frequent and longer-lasting in the Great Plains and Midwest in the last 35 years. What has fueled these storms? The temperature difference between the Southern Great Plains and the Atlantic Ocean produces winds that carry moisture from the Gulf of Mexico to the Great Plains, according to a recent study. […]

  • 6,000 years ago the Sahara Desert was tropical, so what happened?
    on November 30, 2016 at 7:10 pm

    As little as 6,000 years ago, the vast Sahara Desert was covered in grassland that received plenty of rainfall, but shifts in the world's weather patterns abruptly transformed the vegetated region into some of the driest land on Earth. Now a researcher is trying to uncover the clues responsible for this enormous climate transformation -- and the findings could lead to better rainfall predictions worldwide. […]

  • Intensification of land use leads to the same species everywhere
    on November 30, 2016 at 6:39 pm

    In places where humans use grasslands more intensively, it is not only the species diversity that decreases -- the landscape also becomes more monotonous, and ultimately only the same species remain everywhere. This results in nature no longer being able to provide its 'services', which range from soil formation for food production to pest control. 300 scientists have now studied the consequences of land-use intensification across different species groups at the landscape level for the very first time. […]

  • Bioenergy grass can withstand freezing temperatures
    on November 29, 2016 at 6:36 pm

    Prairie cordgrass, a native perennial grass used for biomass energy, is tolerant to salt, flooding, and freezing stress.
