  2. 1. Wooded or treeless pastures? : Linking policy, farmers' decisions and biodiversity

    Author : Simon Jakobsson; Regina Lindborg; Sara A O Cousins; Jan Plue; Tim Benton; Stockholms universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Plant Species Composition and Diversity in Cliff and Mountain Ecosystems

    Author : Henrik Antonsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cliff ecology; bryophytes; biodiversity; beta diversity; dispersal; facilitation; nurse plant; plant-plant interactions; Silene acaulis; stress;

    Abstract : Ecosystems today are under increasing pressure from a rapidly changing climate, changes in land-use, habitat fragmentation and degradation and increasing anthropogenic disturbance. Studying drivers of biodiversity patterns is of increasing importance for understanding the dynamics of communities and their reactions and adaptation to changes in the future. READ MORE

  5. 3. 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

  6. 4. Fungal disease dynamics, genetic variation and biodiversity-yield relationships : — a study along a gradient of coffee management in southwestern Ethiopia

    Author : Beyene Zewdie Hailu; Kristoffer Hylander; Ayco J.M Tack; Jacques Avelino; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Armillaria root rot; biodiversity; biodiversity-yield trade-offs; coffee; Coffea arabica; coffee berry disease; coffee leaf rust; coffee wilt disease; coffee yield; genetic composition; genetic diversity; hyperparasite; management intensity gradient; southwestern Ethiopia; Plant Ecology; växtekologi;

    Abstract : Intensification of agricultural systems is a major threat to the associated biodiversity and could also affect the dynamics of pests and pathogens. One such system that is currently under an intensification trajectory is the production of Arabica coffee. READ MORE

  7. 5. Grassland restoration : Connectivity, plant community change and cows

    Author : Rozália E. Kapás; Sara Cousins; Adam Kimberley; Lars A. Brudvig; Stockholms universitet; []
