  2. 11. Three faces of HELCOM - institution, organization, policy producer

    Author : Matilda Valman; Andreas Duit; Henrik Österblom; Per Olsson; Urika Mörth; Annica Sandström; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Helsinki Commission; institutional change; policy change; organizational response; ecosystem approach; Baltic Sea; BSAP; content analysis; Political Science; statsvetenskap;

    Abstract : Despite early initiatives during the 1960s and 1970s, and continuing efforts ever since, the Baltic Sea remains in poor condition. The Helsinki Commission (HELCOM) is the governing body tasked with protecting the marine environment from further deterioration through intergovernmental collaboration between the Baltic Sea states and the EU.

  4. 12. Future stratospheric ozone depletion will affect a subarctic dwarf shrub ecosystem

    Author : Ulf Johanson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Vaccinium; UVB; subarctic; shoot growth; ozone depletion; leaf thickness; irradiation system; heath ecosystem; Empetrum; dwarf shrubs; Calamagrostis; decomposition; Physiological biophysics; Växtfysiologi;

    Abstract : The stratospheric ozone depletion and the concomitant increase in ultraviolet-B (UV-B, 280-320 nm) radiation is of global concern due to the effects of UV-B on living organisms. To investigate the effects of increased levels of UV-B, a field irradiation system was established at a subarctic dwarf shrub heath in Northern Sweden (68 °N). READ MORE

  5. 13. The palaeolimnological record of regime shifts in lakes in response to climate change

    Author : Linda Randsalu Wendrup; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; palaeolimnology; regime shifts; thresholds; alternative stable states; climate change; ecosystem dynamics; diatoms; hydrocarbons; monitoring; lake sediments; shallow lakes; 8.2 ka event;

    Abstract : Regime shifts in lake ecosystems can occur in response to both abrupt and continuous climate change, and the imprints they leave in palaeolimnological records allow us to investigate and better understand patterns and processes governing ecological changes on geological time scales. This thesis aims at investigating palaeolimnological records of regime shifts in lakes during the Holocene to explore how lake ecosystems responded to climate changes and anthropogenic activities and to identify thresholds or tipping points that produced regime shifts.

  6. 14. In/visible - Conceptualizing Service Ecosystem Design

    Author : Josina Vink; Bård Tronvoll; Bo Edvardsson; Katarina Wetter-Edman; Birgit Mager; Raymond P. Fisk; Karlstads universitet; []
    Keywords : HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; service design; service research; service ecosystems; social structures; systemic design; institutional theory; service-dominant logic; Business Administration; Företagsekonomi;

    Abstract : This thesis explores and advances the evolving understanding of service design in service research. The study problematizes the prevailing view of service design as the design of service offerings to improve customer experiences. READ MORE

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

    Author : Xi Pang; Ulla Mörtberg; Berit Balfors; Brian Fath; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE
