  1. 1. Effect of stand age on soil respiration in managed vs unmanaged Scots pine stands

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

    Författare :Richard Engholm; [2024]
    Nyckelord :chronosequence; soil respiration; total respiration; autotrophic respiration; heterotrophic respiration; forestry;

    Sammanfattning : How the forests in Sweden and around the world have been, and are still today, managed is a hot debate. The rotation forestry that is commonly used in Sweden has been the focus of debate regarding whether it is a sustainable management method, and whether it should be changed. LÄS MER

  3. 2. How do rainfall patterns change microbial induced carbon dynamics in soil?

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Författare :Maria João Silva; [2023]
    Nyckelord :drying and rewetting; bacterial growth; fungal growth; annual crops; perennial crops; soil depth; climate change; biotechnology; Biology and Life Sciences;

    Sammanfattning : Climate change is changing the precipitation patterns around the globe, leading to more extreme weather events like severe drought and heavy rainfalls. These events are intrinsically related to soil moisture fluctuations, which strongly modulates carbon fluxes in terrestrial ecosystems. LÄS MER

  4. 3. Effects of tillage and straw treatments on earthworm abundance : study in two Swedish long-term field trials

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

    Författare :Fredrik Ahlberg; [2023]
    Nyckelord :anecic; conventional tillage; endogeic; no-tillage; reduced tillage;

    Sammanfattning : Earthworms have several functions in the soil, for instance redistribution of organic matter and enhancing plant available nutrients. Earthworms are divided into three ecological groups, with different functions in the soil. The groups are: anecic, endogeic and epigeic. LÄS MER

  5. 4. Effekten av plöjning på biologisk mångfald i jordbruksmark

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

    Författare :Rebecca Björklund; [2023]
    Nyckelord :Earth and Environmental Sciences;

    Sammanfattning : This study was done to get an understanding of how tillage effects biodiversity in agriculture soil. Therefore, this study focused on the soil organisms and various physical and chemical processes that can affect them. LÄS MER

  7. 5. Legacy effects of temperature alterations on microbial resistance and resilience to drying and rewetting

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

    Författare :Franklin Lee Harris; [2023]
    Nyckelord :microbial ecology; soil; carbon dynamics; high latitudes; climate change; moisture stress; isotopes; respiration; trait based ecology; soil microbes; Environmental Changes in High Latitudes EnCHIL ; Earth and Environmental Sciences; Biology and Life Sciences;

    Sammanfattning : With warming in soils due to climate change, a series of secondary factors arise, which have multifaceted effects on soil microbial communities. Of these, alterations to soil moisture are among the most crucial to understanding how microbial functions will change in the face of climate change. LÄS MER
