  1. 1. Marktäckets och markfuktighetens påverkan på blomsterlupinens (Lupinus polyphyllus) utbredning i Jämtland

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Julia Svedh; [2024]
    Nyckelord :Garden lupine; Lupinus polyphyllus; soil moisture; land cover; invasive alien species; Jämtland; ; Blomsterlupin; Lupinus polyphyllus; marktäcke; markfuktighet; invasiva främmande arter; Jämtland;

    Sammanfattning : Biodiversity is the prerequisite for well-functioning ecosystem services that are crucial, like clean water and clean air. Invasive alien species (IAS) are a serious and long-term issue that is actively threatening the genetic diversity within ecosystems. LÄS MER

  3. 2. Mängden död ved i värdekärnor i Söderåsens nationalpark

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Gustav Thurell; [2024]
    Nyckelord :volym död ved; stående död ved; liggande död ved; bokskog; nedbrytningsgrad; värdekärna;

    Sammanfattning : There is a lack of knowledge about the development of the dead wood in former production beech (Fagus sylvatica) forests that have been protected. The present study has been carried out in Söderåsen National Park to compare the distribution of dead wood in relatively unaffected beech forests that have been protected for a long time (A-value cores) and older, previously managed beech forest that has only been protected for 20-30 years (B-value cores).

  4. 3. Förekomst av snöskytte i hyggesfria metoden schackrutehuggning i Västerbotten

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Jenny Johansson; [2024]
    Nyckelord :phacidium infestans; kontinuitetsskogsbruk; Norrland;

    Sammanfattning : Skogen är och har länge varit en viktig resurs för länet Västerbotten och den står för cirka 14 procent av den produktiva skogsmarksarealen i Sverige. Skogen i Västerbotten har brukats sedan medeltiden från småskaligt hushållsbehov till storskaligt skogsbruk i modern tid. LÄS MER

  5. 4. SOIL GROSS NITROGEN MINERALISATION AND FOREST GROWTH IN FOUR HEMIBOREAL FOREST STANDS IN SOUTHWEST SWEDEN

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Linnéa Eriksson; [2023-04-20]
    Nyckelord :soil C:N; forest production; 15N isotope dilution; gross N mineralisation; ammonium; soil carbon; soil nitrogen; root exudates; stoichiometric decomposition; boreal forests; priming; microbial C limitation;

    Sammanfattning : Boreal and temperate forests together make up the largest terrestrial net C sink in the world. They take up carbon dioxide (CO2) from the atmosphere and store it in plant biomass and soil as they grow, making them crucial in mitigating global climate change. LÄS MER

  7. 5. Can urban tree re-inventories inform future species selection? : diameter at breast height as an indicator for tree performance in Malmö municipality’s tree database

    Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Hannah Kit Kraynick Braegelmann; [2023]
    Nyckelord :DBH; ; diameter at breast height; tree inventories; tree re-inventories; urban forestry; species selection; tree management;

    Sammanfattning : Using the inventory database of trees for Malmö municipality, Sweden, this study explored the potential of using the diameter at breast height (DBH) measurement in re-inventories, as a decision-making tool for species selection and management in urban forests. With the escalating pressures of urbanization and unpredictable climate change effects, there is an urgent need for urban forest managers to possess reliable tools that can facilitate the selection of resilient tree species capable of thriving in diverse and changing urban contexts.
