  1. 1. The effect of the COVID-19 lockdown on the spatial ecology of moose in an area with high recreational activity

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

    Författare :Maximilian Dörr; [2024]
    Nyckelord :Moose; Alces alces; habitat selection; tourism; human disturbance; activity; movement; speed; seasons; Covid-19; pandemic;

    Sammanfattning : In diverse landscapes, the coexistence of wildlife habitat requirements and human land use often leads to conflicts, posing challenges for sustainable species management. Recreational activities, especially in sparsely populated areas, frequently disturb wildlife behavior, necessitating a comprehensive assessment of anthropogenic impacts on habitats. LÄS MER

  3. 2. Restaurering av grässandhedar genom aktiv markstörning - en jämförelse av florans kolonisation av plöjningar och sandblottor på Revingefältet utanför Lund

    Master-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Erik Borgström; [2023]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : The conservation value of sandy habitats for a flora and fauna adapted to open, light, dry, warm, and often nutrient-poor conditions, is well recognized. Today this environment is threatened by lack of disturbance, fragmentation and exploitation, acidification and increased levels of nitrogen and phosphorus. LÄS MER

  4. 3. Fungal Effects on Tree Growth in a Primary Succession

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

    Författare :August Hedberg; Julian Säflund; [2023]
    Nyckelord :primary succession; succession; ectomycorrhiza; saprotroph; tree growth; Pinus sylvestris; soil fungi;

    Sammanfattning : In the Boreal zone, ectomycorrhiza is the most common mycorrhiza found among trees and helps with nitrogen and nutrient uptake. Most research on mycorrhiza, its effect, and community development are done on secondary succession (succession in an ecosystem after a disturbance) such as after a clearcut. LÄS MER

  5. 4. Exploring the factors affecting tree establishment after wildfire in a boreal forest in Sweden

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Robert Pim; [2023]
    Nyckelord :tree regeneration; tree establishment; wildfire; boreal forests; disturbance; sapling regeneration; generalized linear mixed models;

    Sammanfattning : The factors affecting tree establishment in boreal forests after fire will help determine the community composition of the regenerating forest. These may have large consequences on the community dynamics for years after the fire disturbance. LÄS MER

  7. 5. 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.
