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

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

    Abstract : 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. READ MORE

  4. 2. Macroalgal community dynamics on coral reefs : Implications for management

    Author : Erik Mörk; Nils Kautsky; Magnus Nyström; Tim R. McClanahan; Stein Fredriksen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Macroalgae; Coral Reefs; Herbivory; Nutrients; Ecosystem change; Fish; Sea Urchins; East Africa; marin ekotoxikologi; Marine Ecotoxicology;

    Abstract : Although rather inconspicuous on healthy coral reefs, macroalgae form the basis of coral food webs. Today, macroalgae are generally increasing and many reefs undergo transitions from coral to macroalgal dominance resulting from e.g. enhanced nutrient loading or increased fishing. READ MORE

  5. 3. Wood-living beetle diversity and Swedish forest management

    Author : Oskar Gran; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biodiversity; forestry; harvest; insects; landscape; management;

    Abstract : Humans have impacted Fennoscandian forests for thousands of years, through grazing, burning, and since the industrial revolution increasingly through efficient industrial forestry. These impacts have changed the composition and structure of these forests, by reducing forest age, simplifying forest structure, and reducing the amount of broadleaved trees, among other things.

  6. 4. Population ecology and management of waders breeding on coastal meadows

    Author : Richard Ottvall; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Animal ecology; Djurekologi; grazing management; population modelling; demography; genetic structure; population decline; Tringa totanus;

    Abstract : Many wader (Charadrii) populations are declining throughout in Europe, but the underlying causes are often poorly known and diverse. To fully grasp the reasons behind declines in vulnerable wader populations, it is crucial to understand the demography. READ MORE

  7. 5. Towards adaptive management of reindeer grazing resources

    Author : Anna Olofsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis aims to create a scientifically founded proposal for improvement of optimal and sustainable use of reindeer pasture resources by an adaptive management approach. Hence, the adaptive management concept is reviewed and discussed with specific reference to reindeer husbandry. READ MORE
