  1. 41. Resource economy of carnivorous plants: Interactions between prey capture and plant performance in three subarctic Pinguicula species

    Författare :Magnus Thorén; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant ecology; income breeder; capital breeder; supplementary feeding; reproductive effort; life-history; cost of reproduction; Växtekologi;

    Sammanfattning : In this thesis, I have studied in situ the resource economy of the three carnivorous plant species Pinguicula alpina, P. villosa and P. vulgaris in a subarctic environment. The prey capture varied among individual plants, years and species. LÄS MER

  3. 42. Climate change impacts upon plants and soils along environmental gradients : insights from Swedish subarctic tundra and boreal forests

    Författare :Jonathan De Long; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Climate change is altering ecosystems worldwide. Despite advances in our understanding of the effects of increasing temperature, little is known about how increased temperatures will impact upon plants and soils across environmental gradients. LÄS MER

  4. 43. Energy efficiency strategies for residential buildings in a subarctic climate: Impacts on energy use and indoor thermal climate

    Författare :Shimantika Bhattacharjee; Lars Stehn; Sofia Lidelöw; Thomas Olofsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggproduktion och teknik; Construction Management and Building Technology;

    Sammanfattning : Adopting energy efficiency strategies in residential buildings are beneficial as these not only improve the energy performance but also improves the indoor thermal climate and minimizes the greenhouse gas emissions. There exist numerous studies on energy efficiency strategies and their influence on indoor thermal climate in residential buildings in cold climates. LÄS MER

  5. 44. Climate-induced ecological change in subarctic lakes - Evidence from biological archives, long-term monitoring, and contemporary field studies

    Författare :Jenny Nilsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Northern lakes have a unique flora and fauna and are sensitive ecosystems that experience rapid rates of change. Multiple environmental changes are currently affecting these lakes, including climate-induced oligotrophication, with nutrient levels decreasing in waters throughout the Scandinavian mountain range.

  7. 45. Outdoor Comfort in Cold Climates : Integrating Microclimate Factors in Urban Design

    Författare :Saeed Ebrahimabadi; Sigrid Reiter; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Architecture; Arkitektur;

    Sammanfattning : Designing urban spaces that provide outdoor comfort is an important but challenging goal in subarctic climates. An approach to urban design that is sensitive to subarctic climatic conditions is essential, but this requires effective incorporation of urban climate knowledge into urban design, which presently is impeded by several barriers.
