  1. 1. Framställandet av en utsläppshandel baserad på näringsämnen inom det svenska jordbruket

    Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Mathias Nilsson; [2023]
    Nyckelord :Baltiska havet; Östersjön; Östersjöområdet; ETS; Emission Trade Systems; NTS; Nutrient Trade System; eutrophication; övergödning; nutrient-based; näringsämnen; ekonomiska styrmedel; styrmedel; naturvårdsverket; Havs-och vattenmyndigheten; HaV; näringsläckage; växthusgas; utsläpp; pollution; Earth and Environmental Sciences;

    Sammanfattning : This study examines the potential of a nutrient-based emissions trading system and focuses on its possible implementation in the Baltic Sea region to address the problem with eutrophication in the inland sea. Emissions trading has proven to be an effective method for reducing greenhouse gas emissions within the EU through the EU ETS. LÄS MER

  3. 2. Reindeer induced changes in vegetation composition and plant traits on a tundra-forest border

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Femke Pijcke; [2019]
    Nyckelord :physical geography; ecosystem analysis; plant functional traits; nutrient allocation; grazing; reindeer; Earth and Environmental Sciences;

    Sammanfattning : Reindeer (Rangifer tarandus) are the most common large herbivores in the arctic. With a habitat spreading over the entire circumpolar region, they can have a substantial effect on plant species composition and ecosystem processes and functions. LÄS MER

  4. 3. Effects of cover crops and limiting resources on biomass allocation in Elymus repens (L.) Gould

    Master-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Ines Prieto; [2017]
    Nyckelord :elymus repens L. gould; couch grass; cover crops; competition; light; nutrients; weeds in organic farming; perennial weed;

    Sammanfattning : Weed control has always been a major challenge in arable lands. Elymus repens (couch grass), a rhizomatous perennial grass, is a particularly problematic weed in both annual and perennial crops in temperate climates. E. repens is dominant particularly in farming systems with no or limited use of herbicides. LÄS MER

  5. 4. RNA-Seq: Yellow Nutsedge (Cyperus esculentus) transcriptome analysis of lipid-accumulating tubers from early to late developmental stages

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Axel Thieffry; [2014]
    Nyckelord :Cyperus esculentus; transcriptome; tubers; RNA-seq; bioinformatics;

    Sammanfattning : Thanks to high amounts of starch and oil amassed in the parenchyma of its tubers, yellow nutsedge (Cyperus esculentus) stands as a unique plant species with regards to nutrient biosynthesis and accumulation in underground organs. In the last decades, understanding of enzymatic processes in lipid, starch and sugar pathways underwent great improvements. LÄS MER

  7. 5. Effects of soil substrate and nitrogen fertilizer on biomass production of Acacia senegal and Acacia sieberiana in North Eastern Uganda

    Master-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Moses Otuba; [2012]
    Nyckelord :Acacia ; nitrogen; fertilizer; growth rate; biomass allocation;

    Sammanfattning : A study on the effects of soil substrate and nitrogen fertilizer on the growth rate and biomass production of Acacia senegal and A. sieberiana in North Eastern Uganda was conducted between February and June, 2012. LÄS MER
