    Abstract : Land use change constitutes a primary driving force in shaping social-ecological systems world wide, and its effects reach far beyond the directly impacted areas. Graph based landscape ecological tools have become established as a promising way to efficiently explore and analyze the complex, spatial systems dynamics of ecological networks in physical landscapes.

  5. 3. Spatial prediction tools for biodiversity in environmental assessment

    Author : Mikael Gontier; Berit Balfors; Ulla Mörtberg; Davide Geneletti; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EIA; SEA; Species distribution modelling; Habitat suitability modelling; Impact prediction; GIS; Urbanisation; Environmental engineering; Miljöteknik;

    Abstract : Human activities in the form of land use changes, urbanisation and infrastructure developments are major threats to biodiversity. The loss and fragmentation of natural habitats are great obstacles for the long term preservation of biodiversity and nature protection measures alone may not be sufficient to tackle the problem.

  6. 4. Mobility and emigration in butterflies

    Author : Karin Enfjäll; Olof Leimar; Michel Baguette; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Keywords: conspecific density; dispersal; evolution; flight-behaviour; information; sexual conflict; social interactions; Ethology and behavioural ecology; Etologi och beteendeekologi; etologi; Ethology;

    Abstract : Because of its implications for the survival of many species, dispersal plays a key role in conservation biology. A good knowledge about the different factors that influence dispersal decisions is crucial for the understanding of inter-population movements. READ MORE

  7. 5. Ecological interactions in human modified landscapes : Landscape dependent remedies for the maintenance of biodiversity and ecosystem services

    Author : Arvid Bolin; Biodiversitet; []
    Keywords : Central place foraging; Agriculture; Competition; Ecosystem service; Species coexistence; bumble bees; landscape ecology; Biodiversity; Agri-environment scheme; Central place foraging; jordbruk; konkurrens; landskaps ekologi; humlor; bin;

    Abstract : Modern agricultural practices have led to an intensification of the agricultural landscape which has negatively affected both biodiversity and the ecosystem services it provides. In my thesis I have used ecological theory of optimal foraging to try and explain how landscape structure, landscape composition and agricultural management can explain the loss of biodiversity and how remedies can efficiently be implemented.
