  1. 1. Utvärdering av biotopvårdande åtgärder i Grimåsbäcken. En analys av fysikaliska egenskaper och sammansättning av makroevertebrater.

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Björn Andermo; [2024-01-22]
    Nyckelord :Channelized streams; retention; biotope preservation; macroinvertebrates; bottom substrate; woody debris.;

    Sammanfattning : Many streams have been exposed to extensive anthropogenic impact for the benefit of forestry and agriculture. The effects has mainly been channelization characterized by lowered and straightened channels. This homogeneous morphology leads to decreased ability to retain water as well as lost connection to the floodplain. LÄS MER

  3. 2. Tillväxt av öring (Salmo trutta) i bastuån : Täthets- och temperaturberoende?

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Fredrik Curman; [2024]
    Nyckelord :;

    Sammanfattning : Performance of stream living juvenile brown trout (Salmo trutta) may be affected by both intra- and intercohort competition. In this study I examined if growth and density of cohorts of young-of the-year (0+) trout are dependent on temperature and density of older (>0+) trout and 0+ trout. LÄS MER

  4. 3. Weather Factors and E. coli Concentration in Barnviken, Malmö - A Linear Mixed Model Approach

    Kandidat-uppsats, Lunds universitet/Statistiska institutionen

    Författare :Elias Gullberg; [2024]
    Nyckelord :Linear Mixed Models; Mathematics and Statistics;

    Sammanfattning : Barnviken in Malmö has persistently encountered challenges associated with elevated concentrations of Escherichia coli (E. coli) without a discernible source of contamination. LÄS MER

  5. 4. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Rasmus Staaf; [2024]
    Nyckelord :artificial waterways; riparian zone; novel ecosystems; ; forestry; ditch network maintenance; species richness; hill-diversity; drainage ditches; coarse woody debris; ditch cleaning; ecology;

    Sammanfattning : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

  7. 5. Shower Routine Creation: Application Design in a User-Centered Process

    Master-uppsats, Lunds universitet/Ergonomi och aerosolteknologi

    Författare :Jakob Sjödin; Teodor Ahlinder; [2024]
    Nyckelord :user-centered design; shower; routine; user testing; Technology and Engineering;

    Sammanfattning : A shower routine is a sequence of instructions that can be executed by a smart shower. This report explores how interfaces for creating shower routines can be designed. It further investigates the features that users prioritize in such an interface and how shower routines can enhance the shower experience. LÄS MER
