  1. 1. Estimation of Site-Specific Biomass and Leaf Area Index in a Young Scots pine Stand in Southern Sweden

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Olamide Michael Adu; [2023]
    Nyckelord :Scots pine; Biomass estimation; Leaf area index; Model validation; Site-specific models;

    Sammanfattning : Accurate biomass and leaf area index (LAI) estimation are crucial for understanding forest productivity and carbon dynamics. Models are crucial to estimating forest biomass and LAI. This study aimed to estimate site-specific aboveground biomass and LAI in a young Scots pine stand in southern Sweden. LÄS MER

  3. 2. Tritrophic interactions with Silphium integrifolium at the axis : elucidating the role of arbuscular mycorrhizal fungal species on plant phenotype

    Master-uppsats, SLU/Dept. of Plant Protection Biology

    Författare :Philipp Hansen; [2023]
    Nyckelord :Arbuscular mycorrhiza; mycorrhizal responsiveness; induced plant volatiles; Silphium integrifolium Silflower ; perennial grains; new crops; ecological intensification;

    Sammanfattning : A fundamental understanding of the intricate interactions between crops and their environment may help guide the development of ecologically intensified agriculture. Arbuscular mycorrhizal fungi (AMF) are root symbionts that can increase a plant’s access to soil resources and have been found to reprogram plant defensive mechanisms, potentially influencing the performance of plant antagonists.

  4. 3. Forest Aboveground Biomass Monitoring in Southern Sweden Using Random Forest Modelwith Sentinel-1, Sentinel-2, and LiDAR Data

    Magister-uppsats, Högskolan i Gävle/Samhällsbyggnad

    Författare :Wan Ni Lin; [2023]
    Nyckelord :Aboveground biomass; Sentinel-1; Sentinel-2; LiDAR; random forest; GEE;

    Sammanfattning : Monitoring carbon stock has emerged as a critical environmental problem among several worldwide organizations and collaborations in the context of global warming and climate change. This study seeks to provide a remote sensing solution based on three types of data, to explore the feasibility and reliability of estimating aboveground biomass (AGB) in order to improve the efficiency of monitoring carbon stock.

  5. 4. Emissions of nitrous oxide associated with frost killed cover crops

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Felicia Olofsson; [2022]
    Nyckelord :Nitrous oxide; cover crops; greenhouse gases; freeze-thaw cycles;

    Sammanfattning : Agriculture is responsible for approximately 80% of anthropogenic emissions of the potent and long-lived greenhouse gas nitrous oxide (N2O). N2O emissions from agricultural soils are characterized by high temporal and spatial variability and often peak in short bursts related to events such as precipitation, fertilization and soil thawing.

  7. 5. Forest structure of Dalby Söderskog National Park : patterns of carbon storage in living and dead trees

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Kumetra Achuthan; [2021]
    Nyckelord :ash dieback disease; deadwood; Dutch elm disease; living tree volume; coarse woody debris; carbon stock and storage; pest invasions; temperate mixed broadleaved forest;

    Sammanfattning : Carbon sequestration and storage is an ecosystem service supplied by forests, and is of increasing importance in the context of mitigation of global climate change. Forest pest invasions, driven primarily by globalizations, represent a risk to the efficiency of carbon sequestration as they may greatly reduce the amount of the living biomass in forests. LÄS MER
