  2. 1. Plant-associated soil communities : Patterns, drivers and aboveground consequences

    Author : Pil Uthaug Rasmussen; Ayco J. M. Tack; Martijn Bezemer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aboveground-belowground interactions; arbuscular mycorrhiza; climate; dispersal; environmental drivers; fungi; genetic variation; nematodes; plant-herbivore interactions; soil communities; spatial patterns; ekologi och evolution; Ecology and Evolution;

    Abstract : Soil contains a wealth of diversity – bacteria, fungi, nematodes, arthropods and earthworms are just some of the many organisms found belowground. These organisms play an important role in shaping the soil environment and they strongly influence plant fitness, diversity and community composition. READ MORE

  4. 2. Soil microbial responses to mild winters and seasonal change

    Author : Johanna Birgander; Biodiversitet; []
    Keywords : Arbuscular mycorrhizal fungi AMF ; RESPIRATION; Stable isotope; Fungal growth; PLFA; NLFA; Microbial community composition; bacterial growth; Aboveground-belowground interactions; Temperature adaptation; Climate change;

    Abstract : The aim with this thesis work was to study microorganisms response to milder winters, different seasons, and altered temperature. Winter warming treatments were established in a semi-natural temperate grassland, simulating mild winters for two years. READ MORE

  5. 3. Biogeochemistry in Subarctic birch forests : Perspectives on insect herbivory

    Author : Jeppe Ågård Kristensen; MERGE: ModElling the Regional and Global Earth system; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biogeochemistry; Aboveground-belowground interactions; Herbivory; Insects; Subarctic; Birch; soil microbes;

    Abstract : Herbivory can influence ecosystem processes, partly through long-term changes of the plant community compositions, but also more rapidly through the herbivores’ digestive alteration of the organic matter that is cycled through the soil and back to the primary producers. In the Subarctic mountain birch (Betula pubescens ssp. READ MORE
