1. 1. Plant species diversity patterns in a Swedish rural landscape : effects of the past and consequences for the future

   Författare :Sara A. O. Cousins; Roy Haines-Young; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Plant species richness in rural landscapes is threatened as grassland management ceases or changes, and as many remaining semi-natural grasslands are becoming increasingly fragmented. This thesis is a study of plant species diversity in a rural landscape in south-eastern Sweden, and its relationship to management history and landscape pattern. LÄS MER

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

   Författare :Nina Roth; Sara A. O. Cousins; Carly Stevens; Stockholms universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

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

   Författare :Emelie Waldén; Regina Lindborg; Sara A O Cousins; Erik Öckinger; Aveliina Helm; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biodiversity; Ecosystem services; Farmer; Landscape ecology; Plant; Policy; Restoration; Semi-natural grassland; Biologisk mångfald; Ekosystemtjänster; Landskapsekologi; Lantbrukare; Naturbetesmark; Policy; Restaurering; Växter; Äng; Physical Geography; naturgeografi;

   Sammanfattning : 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. LÄS MER

5. 4. Wooded or treeless pastures? : Linking policy, farmers' decisions and biodiversity

   Författare :Simon Jakobsson; Regina Lindborg; Sara A O Cousins; Jan Plue; Tim Benton; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bat; biodiversity; bird; canopy cover; Common Agricultural Policy; European Union; farmer; functional diversity; germination; grassland; multi-taxa; pasture; plant; policy; seed sowing; tree density; trees; Physical Geography; naturgeografi;

   Sammanfattning : Worldwide, biodiversity conservation is one of the key challenges for a sustainable future of nature and society. It is particularly important to preserve high quality habitats within otherwise intensively managed agricultural landscapes. LÄS MER

7. 5. Plant community assembly in grazed grasslands

   Författare :Bryndís Marteinsdóttir; Eriksson Ove; Cousins Sara A. O.; Johan Ehrlén; Meelis Pärtel; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Assembly rules; dispersal limitation; environmental filtering; establishment limitation; ex-arable fields; functional traits; landscape history; semi-natural grasslands; seed bank; seed augmentation; seed rain; trait based filtering; Plant Ecology; växtekologi;

   Sammanfattning : 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. LÄS MER
