  1. 1. Land Use Change in Space and Time : implications for plant species conservation in semi-natural grasslands

    Författare :Regina Lindborg; Ove Eriksson; Johan Ehrlén; Thomas Elmqvist; Markus Fischer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diversity; management; restoration; landscape; history; Population viability analysis; seed-sowing; Primula farinosa; Campanula rotundifolia; grazing; fragmentation; extinction risk; Biology; Biologi;

    Sammanfattning : Land use change has during the last century altered the traditional rural landscape in Sweden, resulting in a major decline in species diversity. Traditional small-scale farming, with a remarkably high small-scale species richness, has changed in favour of rationalized agriculture, and many semi-natural grasslands, i.e. LÄS MER

  3. 2. Agricultural expansion impacts on wetland ecosystem services from Kilombero Valley, Tanzania

    Författare :Edmond Alavaisha; Regina Lindborg; Steve Lyon; Jennie Barron; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecosystem services; land use change; management practices; fertilization; irrigation; water quality; and smallholder; Physical Geography; naturgeografi;

    Sammanfattning : Land use change has major impact on the world’s wetland ecosystems and biodiversity. The motivation behind this change has been to increase agricultural production, often resulting in negative effects on water quality and soil fertility. LÄS MER

  4. 3. Urban shades of green : Current patterns and future prospects of nature conservation in urban landscapes

    Författare :Sara Borgström; Regina Lindborg; Sara Cousins; Thomas Elmqvist; Christer Nilsson; Stockholms universitet; []
    Nyckelord :urbanisation; nature conservation; urban planning; urban systems; nature reserves; Sweden; NATURAL SCIENCES; NATURVETENSKAP; naturresurshushållning; Natural Resources Management;

    Sammanfattning : Urban nature provides local ecosystem services such as absorption of air pollutants, reduction of noise, and provision of places for recreation, and is therefore crucial to urban sustainable development. Nature conservation in cities is also part of the global effort to halt biodiversity decline. 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. Woody or treeless pastures? Effects of EU tree density limitations on biodiversity in woody pastures

    Författare :Simon Jakobsson; Regina Lindborg; Tomas Pärt; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The high biological and cultural values of traditionally managed rural landscapes are threatened by habitat change and degradation due to homogenisation through modern agricultural practices and abandonment. Woody pastures are important for many different taxa, and hence crucial for biodiversity conservation in these agricultural landscapes. LÄS MER
