  2. 1. Grasslands in a changing climate : Summer drought and winter warming effects on grassland vegetation

    Author : Nina Roth; Sara A. O. Cousins; Carly Stevens; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biodiversity; climate change; compost; floral resources; grasslands; in-situ experiments; mowing; nectar; open-top chambers; plants; rain-out shelters; sheep grazing; soil amendments; summer drought; winter warming; naturgeografi; Physical Geography;

    Abstract : Grasslands harbour a high biodiversity of both plants and animals, and they provide many ecosystem services such as fodder production, pollination, and carbon storage. Climate change is likely to alter grassland ecosystems, with the effects varying according to the exact nature and timing of changes. READ MORE

    Abstract : Species assembly into local communities from the surrounding region can be caused either by species failure to reach the site (i.e. seed limitation) or to establish (i.e. READ MORE

  6. 4. Restoration of semi-natural grasslands : Impacts on biodiversity, ecosystem services and stakeholder perceptions

    Abstract : Humans play a major role shaping the living conditions for not only ourselves, but also all other species on Earth. In fact, some species-rich habitat types require human management to uphold the biodiversity and related ecosystem services. READ MORE

  7. 5. Conservation of semi-natural grasslands : Effects of different management methods on biodiversity

    Author : Malin Tälle; Lars Westerberg; Per Milberg; Uno Wennergren; Hans Henrik Bruun; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Species-rich semi-natural grassland are valuable habitats in the agricultural landscape as they may contain a high diversity of both plant and animal species, as well as provide essential ecosystem services like pollination. To keep these habitats open and to maintain the biodiversity in them, management like grazing or mowing is necessary. READ MORE
