  1. 1. Evaluating the effects of climate change on Arctic char : including impacts of brown trout competition

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Ola Carlström; [2023]
    Nyckelord :arctic char; brown trout; climate change; diet; habitat use; temperature;

    Sammanfattning : Climate change is predicted to increase the average global temperature with 1.5 °C between 2030 and 2052. The areas that are most vulnerable for climate change are the arctic regions. Arctic char (Salvelinus alpinus) is a cold-water salmonid species with the most northern distribution of all freshwater fish species. LÄS MER

  3. 2. Effects of soil factors on pioneer bryophyte species composition

    Master-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Dora Mijić; [2023]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Bryophytes play a significant role in various ecological processes, including soil succession and colonization after disturbances. Although they are commonly believed to take up nutrients from soil solutions rather than the soil itself, the influence of soil on their growth and distribution is evident from previous studies.

    Nyckelord :Weighted Usable Area WUA ; minimitappning; HEC-RAS; salmo; Helge å; den nationella planen för omprövning av vattenkraft NAP ; Technology and Engineering;

    Sammanfattning : Hydropower is the dominant source of electricity in Sweden, constituting 45% of the national supply. While pivotal for decarbonization and climate goals, its environmental impact on freshwater biodiversity is concerning. LÄS MER

  5. 4. Den svarthuvade snigelns (Krynickillus melanocephalus) substratpreferens vid äggläggning

    Kandidat-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Författare :Geir Brodén; [2023]
    Nyckelord :Krynickillus melanocephalus finns ingen engelsk översättning ; Ecology; Slugs; Pest; Invasive species; Substrate preference; Oviposition; Egg laying; Fältsnigel; Ekologi; Äggläggning; Habitat; Substrat; Invasiv; Svarthuvad snigel;

    Sammanfattning : Krynickillus melanocephalus was first seen in Sweden 2015. It is now labeled as an invasive species and it potentially poses a threat to the ecosystem, but the slug has not yet shown to have great negative impact in gardens and agricultural fields. There is limited ecological knowledge about the species. LÄS MER

  7. 5. Habitatpreferens hos Anguilla anguilla: makrofyters påverkan på gulålars habitatval under dag och natt

    Kandidat-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Författare :Hannah Wiklund; [2023]
    Nyckelord :European eel; Anguilla anguilla; Yellow eel; Habitat preference; Macrophytes; Substrate; Europeisk ål; Anguilla anguilla; Gulål; Habitatpreferens; Makrofyter; Substrat;

    Sammanfattning : Aquatic vegetation and different substrates can be important factors for fish habitat. The European eel (Anguilla anguilla) is threatened by habitat loss in freshwater systems during its life stage as a yellow eel. To conserve the species, restoration measures and increased knowledge about its preference for benthic habitats are needed. LÄS MER
