  1. 6. Skyddet av biologisk mångfald vid jakt : en studie om rättens förhållande till komplexa och dynamiska ekosystem tillämpat på uttag av viltarter

    Författare :Anna Christiernsson; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Law; Rättsvetenskap;

    Sammanfattning : Biological diversity, or the variety of genes, species and ecosystem, is fundamental to all life on Earth. The conservation of biodiversity is consequently recognized both in national and international law as one of the prerequisites for achieving a sustainable development. However, the decrease in biodiversity is continuing, at all levels. LÄS MER

  3. 7. The importance of biodiversity for ecosystem processes in sediments : experimental examples from the Baltic Sea

    Författare :Johan Näslund; Jonas Gunnarsson; Sara Sjöling; Nils Kautsky; Antoine Grémare; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biodiversity; Soft-bottom sediment; Ecosystem processes; Ecosystem function; Benthic-pelagic coupling; Baltic Sea; Trophic interactions; Pollutant biodegradation; Organic matter mineralization; Deposit feeder; Detritivore; Invasive species; Marine ecology; Marin ekologi; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : Aquatic sediments are, by surface, the largest habitat on Earth. A wide diversity of organisms inhabit these sediments and by their actions they have a large influence on and also mediate many ecosystem processes. LÄS MER

  4. 8. Biodiversity and green infrastructure in urban landscapes

    Sammanfattning : In this thesis, I evaluate the extent to which biodiversity is affected, and taken into consideration by, urban planning. Based on landscape ecology, I apply an interdisciplinary approach. LÄS MER

  5. 9. Naturvetenskap i tillblivelse : Barns meningsskapande kring biologisk mångfald och en hållbar framtid

    Författare :Cecilia Caiman; Iann Lundegård; Per-Olof Wickman; Johan Öhman; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; meaning making; science education; preschool children; education for sustainability; naturvetenskapsämnenas didaktik; Science Education;

    Sammanfattning : The objective of this thesis is to analyze children’s meaning making processes in science related to environment and sustainability at the pre-school level. This thesis examines an approach to early childhood education which is conceptualized by an explorative as well as a listening approach that specifically addresses children’s questions. LÄS MER

  7. 10. Managing mountains, past and present conditions for traditional summer farming and Sami reindeer husbandry in northern Scandinavia

    Författare :Weronika Axelsson Linkowski; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Traditional land use and conditions for maintenance of biodiversity are often interlinked. When land use changes and ecosystems change as a result, there is a risk to loose both the traditional ecological knowledge and the biodiversity connected to this land use. LÄS MER
