  1. 16. A remote-sensing approach to studying drought resistance in Swedish old-growth and production forests

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Julika Wolf; [2020]
    Nyckelord :Physical Geography and Ecosystem Analysis; drought impacts; old-growth forests; forest management; remote sensing; Earth and Environmental Sciences;

    Sammanfattning : Boreal forest ecosystems are predicted to experience hotter and drier summers due to climate change, leading to more frequently reduced soil water availability and an increased risk of droughts, as was already the case in Northern Europe during the severe summer drought of 2018. Prolonged water stress in forest ecosystems can lead to impacts ranging from reduced photosynthesis to forest dieback. LÄS MER

  3. 17. Optimal Pitch Distance and Tilt Angleof PV Power Plant for Different Climate

    Master-uppsats, Högskolan Dalarna/Energiteknik

    Författare :Mohamad Alsulaiman; Najmeh Mohammadi; [2020]
    Nyckelord :Pitch distance; Tilt angle; LCOE; Optimization; Configuration; Large scale PV plant;

    Sammanfattning : Finding the optimum inter-row spacing and installation tilt for tilted or ground mounted PV systems is a big issue in designing the large-scale PV systems. Increasing the array spacing leads to higher annual generated energy because of the reduced impact of row-shading, but on the other hand, it increases costs of land purchase/lease and wiring costs.

  4. 18. Investigating Sand Dune Location, Orientation and Geomorphometry Through GEOBIA-Based Mapping: A Case Study in Northern Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Melanie Stammler; [2020]
    Nyckelord :sand dunes; geomorphological mapping; object-based image analysis; landscape development; sanddyner; geomorfologisk kartläggning; geografisk objektbaserad bildanalys; landskapsutveckling;

    Sammanfattning : Climate change has repeatedly been framed as the defining issue of the Anthropocene and with the Arctic changing at unpreceded speed need is high for a profound understanding of the Northern Swedish landscape. Northern Swedish aeolian sand dunes have been impacted by climatic changes throughout time. LÄS MER

  5. 19. Validation of Theoretical Approach to measure Biodiversity using Bird Species of a Seminatural Grassland in Sweden

    Magister-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Henry Toe; [2020]
    Nyckelord :;

    Sammanfattning : Biodiversity is a term that has recently been widely used. It is the variety and variability among living organisms and the ecological complexes in which they occur. LÄS MER

  7. 20. Plant functional diversity across a spatial climate gradient in Sweden

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Nina Lončarević; [2019]
    Nyckelord :landscape ecology; plant functional ecology;

    Sammanfattning : Introduction. Climate is a well-known and well-studied abiotic driver of the natural world working through e.g. physiological alterations in species, changes in species’ ranges and growing season, reduction in growth or causing mortality. LÄS MER
