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

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Richard Engholm; [2024]
    Keywords : chronosequence; soil respiration; total respiration; autotrophic respiration; heterotrophic respiration; forestry;

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

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

    Abstract : 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. READ MORE

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

    University essay from SLU/Dept. of Soil and Environment

    Author : Fredrik Ahlberg; [2023]
    Keywords : anecic; conventional tillage; endogeic; no-tillage; reduced tillage;

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Franklin Lee Harris; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 5. Controls of the partitioning of nitrate between DNRA and denitrifiers

    University essay from SLU/Dept. of Forest Mycology and Plant Pathology

    Author : Frida Lindvall; [2022]
    Keywords : DNRA; denitrification; microcosm; experiment; arable soil;

    Abstract : In arable soils, the importance of denitrification, a respiratory process where nitrate (NO3-) is stepwisely reduced to nitrogen gas and nitrous oxide (N2O) is well established. More recently has dissimilatory nitrate reduction to ammonium (DNRA) gained interest as its importance in agricultural soils might have been largely overlooked. READ MORE
