  1. 1. Cooperation and conflict during reproduction in polyterritorial wood warblers (Phylloscopus sibilatrix)

    Författare :Susanne Stenius; Trond Amundsen; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; zoologi; Zoology;

    Sammanfattning : In this thesis, the reproductive strategies of male and female wood warblers are studied. Males which arrived early to the breeding grounds had higher reproductive success than later males. This was due to early males more often mating polygynously than late males. LÄS MER

  3. 2. The return of the wolf : effects on prey, competitors and scavengers

    Författare :Camilla Wikenros; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Apex predators may have both direct and indirect effects on other species through predation and competition. I investigated the effects of wolves (Canis lupus) on prey species, competitors (including humans) and the scavenging guild after the re-colonization by wolves of the Scandinavian Peninsula. LÄS MER

  4. 3. Assessing District-Heating Sustainability – Case Studies of CO2 Mitigation Strategies and Environmental Cost Accounting

    Författare :Elsa Fahlén; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; absorption cooling; biomass gasification; bio transport fuel; policy instruments; carbon dioxide; external costs; combined heat and power; district heating and cooling;

    Sammanfattning : District heating (DH) may play an important role in achieving the EU goal of a secure, competitive and sustainable energy supply. Integrated energy solutions based on technologies, such as biomass gasification for transport fuel, electricity and heat production and heat-driven absorption cooling, create new optimisation possibilities through the linkage between heat, power, cooling and transport fuel markets which may reduce the global warming contribution of the energy sector.
