  1. 16. Biogeochemistry and Peat Properties of Restored Peatlands

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

    Författare :Pelle Belaieff Kronborg; [2022]
    Nyckelord :Drainage; Bulk density; Nitrogen; Carbon; Stable isotopes;

    Sammanfattning : Globally, peatlands comprise the most important soil organic carbon pool storing approximately one third of all terrestrial soil carbon. Drainage can turn peatlands to net sources of carbon dioxide. Peatlands have historically been drained to increase the productivity of agriculture and forestry. LÄS MER

  3. 17. POLLINATION ECOLOGY OF PEDICULARIS SCEPTRUM-CAROLINUM : An investigation on flower visits in northern Sweden

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

    Författare :Johan Närvä; [2022]
    Nyckelord :Pedicularis sceptrum-carolinum; Pollination; Pollination ecology; Pollinators; Bumblebees.;

    Sammanfattning : Pedicularis sceptrum-carolinum is threatened in much of its geographic range. As it reproduces vegetatively only to a limited extent, the species relies heavily on pollinators for reproduction. One aspect often overlooked in restoration efforts is the pollination ecology of flowering plants and their pollinators. LÄS MER

  4. 18. Impacts of peatland drainage on soil properties : a study of drainage effects on boreal peatlands in northern Sweden

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

    Författare :Frederika Klaus; [2022]
    Nyckelord :Boreal peatlands; Bulk density; Carbon; Greenhouse gas; Isotopes; Nitrogen; Organic matter; Peatlands; Peatland drainage; Peatland restoration;

    Sammanfattning : Peatlands cover approximately 3% of the terrestrial surface on Earth and perform several important ecosystem functions, such as carbon storage and water retention. During the late 19th and early 20th centuries, approximately 2 million hectares of peatlands in Sweden were drained to manage the land for forestry and agriculture. LÄS MER

  5. 19. Populationsförstärkande utplantering av martorn, Eryngium maritimum : miljöfaktorers inverkan på populationsutvecklingen hos unga, utplanterade bestånd i Västra Götalands län

    Kandidat-uppsats, SLU/Dept. of Ecology

    Författare :Clara Lerbro; [2022]
    Nyckelord :Bohuslän; Eryngium maritimum; martorn; populationsutveckling; restaurering; uppdrivning; utplantering; Västergötland; Västra Götaland;

    Sammanfattning : Martorn (Eryngium maritimum) är en taggig, perenn ört som växer på sandiga havsstränder med god ljustillgång och är i Sverige en hotad art i kategorin ’sårbar’ (VU) på den nationella rödlistan. Bevarandearbete i form av uppdrivning och utplantering av plantor har genomförts av Länsstyrelsen i Västra Götaland sedan 2016. LÄS MER

  7. 20. Älgbete i restaureringsbränning : älgens respons på brand

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

    Författare :Albin Björnudd; Svante Brus; [2022]
    Nyckelord :älg; viltbete; naturvårdsbränning; tall; biologisk mångfald;

    Sammanfattning : The moose is an important resource for Sweden but causes problems for forestry. Moose browsing damages annually cost forestry large amounts of money which makes it a hot topic of discussion. LÄS MER
