  1. 1. Sustainable development and tourism in a biosphere reserve : A case study of Lake Vänern Archipelago Biosphere Reserve, Sweden

    Författare :Fredrik Hoppstadius; Margareta Dahlström; Cecilia Möller; Jarkko Saarinen; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sustainable Development; Sustainable Tourism; Biosphere Reserves; Place; Landscape; Kulturgeografi; Human Geography;

    Sammanfattning : In this thesis I analyse sustainable development by researching tourism in a biosphere reserve. Sustainable development is based on a broad range of environmental, economic and social elements, bound together by the fact that development is limited by boundaries in the environment. LÄS MER

  3. 2. Exposing the Dark Microbial Biosphere

    Författare :Valerie Hubalek; Stefan Bertilsson; Alexander Eiler; Tim Urich; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Dark biosphere research has been widely neglected, although by volume this biome comprises the lion’s share of habitats on our planet. In these systems the main metabolic strategies are of chemotrophic nature, leading to gradual depletion of redox gradients essential for sustaining life. LÄS MER

  4. 3. Structure and function of microbial communities in acid sulfate soil and the terrestrial deep biosphere

    Författare :Xiaofen Wu; Mark Dopson; Ricardo Amils; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular phylogeny; acid sulfate soils; metal; acidophiles; deep biosphere; oligotrophy; biofilm formation; metagenome; binning; metabolism; Mikrobiologi; Microbiology;

    Sammanfattning : This thesis describes the use of different DNA sequencing technologies to investigate the structure and function of microbial communities in two extreme environments, boreal acid sulfate soil and the terrestrial deep biosphere.The first of the two investigated environments was soils containing un-oxidized metal sulfides that are termed ‘potential acid sulfate soil’ (PASS) materials.

  5. 4. Financial institutions, companies, and the biosphere

    Författare :Alice Dauriach; Victor Galaz; Beatrice Crona; Jan Bebbington; Örjan Sjöberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; vetenskap om hållbar utveckling; Sustainability Science;

    Sammanfattning : International organisations, governments and civil society have become increasingly vocal in their demands that financial institutions take social and environmental responsibility for the companies they invest in. Some financial institutions have started to assume this responsibility in practice by building international alliances and standards, by reallocating their capital, and by trying to influence corporate policies towards environmental and social goals.

  7. 5. Diversity of aquatic viruses from genes to host interactions

    Författare :Emelie Nilsson; Karin Holmfeldt; Martha Clokie; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microbial ecology; bacteriophage; ‘omics; isolation; host range; temporal variation; deep biosphere; Baltic Sea; Akvatisk ekologi; Aquatic Ecology; Mikrobiologi; Microbiology;

    Sammanfattning : Viruses are the most numerous entities on Earth, and can be found in all waters. In aquatic ecosystems, viruses are key players since they alter the way energy and nutrients are transferred by killing larger organisms. LÄS MER
