  1. 11. Spatial Modelling of Coastal Fish – Methods and Applications

    Författare :Göran Sundblad; Ulf Bergström; Alfred Sandström; Peter Eklöv; Christian Möllmann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; habitat; niche; species distribution modelling; juvenile; fish; larvae; spawning; Marine ecology; Marin ekologi; NATURAL SCIENCES; NATURVETENSKAP; Freshwater ecology; Limnisk ekologi; Biology; Biologi; Biology with specialization in Limnology; Biologi med inriktning mot limnologi; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology; Limnologi; Limnology;

    Sammanfattning : Environmental factors influence species and habitats on multiple scales creating a mosaic of distribution patterns. Studying factors shaping these patterns are central to our understanding of population dynamics and ultimately ecosystem functioning. LÄS MER

  3. 12. Towards co-management of Gialova Lagoon : A Natura 2000 coastal wetland in Messinia, Greece

    Författare :Georgios Maneas; Håkan Berg; Stefano Manzoni; Ernsteins Raimonds; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Salinity; wetland restoration; ecosystem services; participatory modelling; social-ecological system; naturgeografi; Physical Geography;

    Sammanfattning : The management of Natura 2000 sites is considered as the cornerstone for the conservation and restoration of biodiversity within Europe. However, protected ecosystems provide a plethora of benefits to local societies, and support the local economy. LÄS MER

  4. 13. Structure and Stability of Ecological Networks : The role of dynamic dimensionality and species variability in resource use

    Författare :David Gilljam; Bo Ebenman; Peter Münger; José Montoya; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The main focus of this thesis is on the response of ecological communities to environmental variability and species loss. My approach is theoretical; I use mathematical models of networks where species population dynamics are described by ordinary differential equations. LÄS MER

  5. 14. Wild bees in agricultural landscapes: Modelling land use and climate effects across space and time

    Författare :Maria Blasi Romero; Centrum för miljö- och klimatvetenskap (CEC); []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Wild bees; Agricultural landscapes; climate change and agriculture; Phenology; Land-use; Model transferability; Ecological models; Pollination;

    Sammanfattning : Wild bees are declining in many parts of the world, which poses a risk for crop pollination and ecosystem health. Land use and climate change are two of the main drivers of the decline, and understanding the interactive effects of these two drivers and wild bees is very important to be able to develop proper responses and mitigate future negative effects.

  7. 15. Trade-off analysis of forest ecosystem services – A modelling approach

    Författare :Xi Pang; Ulla Mörtberg; Berit Balfors; Brian Fath; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Forest bioenergy feedstock; Landscape simulation; Forest simulation; Ecosystem services modelling; Integrated sustainability assessment; Spatial optimization; Optimization heuristics; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : Forest is a resource that is increasingly utilized for multiple purposes. The balance between energy demands and the long-term capacity of ecosystems to support biodiversity and other ecosystem services is crucial. LÄS MER
