  1. 1. Effekter av torka och vall på marklevande nematoder

    Kandidat-uppsats, SLU/Dept. of Ecology

    Författare :Linda Nilsson; [2022]
    Nyckelord :nematoder; torka; markfuktighet; vall; växtföljd;

    Sammanfattning : Nematoder finns i stora mängder i marken och påverkar jordbruket på flera sätt. Det finns nematoder som har en positiv inverkan då de bidrar till markens näringsomsättning och mobiliserar kväve men det finns även växtätande nematoder som kan orsaka skördeförluster. LÄS MER

  3. 2. Implications of a dynamic vertical root distribution for modelled water and carbon fluxes across selected ecosystems : incorporating a novel rooting scheme into LPJ-GUESS

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

    Författare :Lasse Keetz; [2019]
    Nyckelord :Physical Geography and Ecosystem Analysis; Ecosystem Modelling; LPJ-GUESS; Vertical Root Distribution; Dynamic Root Distribution; Carbon and Water Fluxes; Earth and Environmental Sciences;

    Sammanfattning : Roots play a key role in terrestrial carbon and water cycles, and therefore for the global climate system. They mediate plant evapotranspiration, influence photosynthetic processes and are responsible for atmospheric carbon transport into the pedosphere. Fine roots, in particular, are chiefly regulating water and nutrient uptake. LÄS MER

  4. 3. Vegetation responses to summer- and winter warming : flower power in the Alaskan tussock tundra?

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

    Författare :Maja Wressel; [2018]
    Nyckelord :Arctic vegetation; snow depth; warming; vertical root distribution; tundra;

    Sammanfattning : Plants have an important role in the tundra carbon (C) cycle by storing C in primary production and thus potentially counteract the C released from thawing permafrost. Tundra vegetation is limited by nitrogen (N), which is predicted to increase with rising temperatures and increased snow depth. LÄS MER

  5. 4. The Vertical Route Forecast : an Evaluation of a New Flight Path Based Weather Forecast Product with HARMONIE-AROME High Resolution Forecasts over Scandinavia

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Ingela Leffler; [2017]
    Nyckelord :Vertical route forecast; Model evaluation; HARMONIE-AROME; GFS; Aviation weather; Vertikal ruttprognos; Modellutvärdering; HARMONIE-AROME; GFS; Flygväder;

    Sammanfattning : As a complement to existing weather forecast products for aviation, a prototype of a new product is presented and evaluated. It shows the atmosphere in a vertical cross section along the intended route. LÄS MER

  7. 5. Commercial eucalyptus plantations with Taungya system in Lao PDR: analysis of tree root biomass

    Kandidat-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Simon Edberg; [2015]
    Nyckelord :eucalyptus; agroforestry; root development; root system; Southeast Asia;

    Sammanfattning : The increasing demand for wood, fibre and pulp coupled with efforts to mitigate greenhouse gas emission has put immense importance on the development of forest plantations. The rapidly growing human population will also face shortage of food, particularly in developing world where agricultural productivity is generally low. LÄS MER
