  2. 11. 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. 12. Niche differentiation of ammonia oxidizing bacteria and archaea in managed soils

    Author : Ella Wessén; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Soils offer humanity a multitude of ecosystem services, including production of food and clean drinking water, and many such services are driven by soil microbial communities. However, human activities are constantly affecting soil ecosystems through altered land use or various management strategies, and thereby influence microbial communities and their functions.

  5. 13. Imprint of management on microbial communities in arable soil : implications for N2O emissions

    Author : Tina Putz; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Arable soils are a major source of the greenhouse gas nitrous oxide (N2O), emissions of which are directly linked to increased use of N fertilizers. Microbial communities that drive N cycle processes in soil ultimately determine the fate of reactive N inputs and control N2O emissions. READ MORE

  6. 14. Decomposition of soil organic matter under a changing climate : a matter of efficiency?

    Author : Tobias Bölscher; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Soil organic matter is the largest carbon (C) pool in the terrestrial C cycle, and soil CO₂ emissions surpass anthropogenic emissions from fossil fuel combustion by a factor of nine. Therefore, mechanisms controlling C stabilisation in soils and its feedback to climate change are widely debated. READ MORE

  7. 15. Who comes first? Implications of the plant-microbiome-soil continuum feedback on plant performance

    Author : David Castro; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Plants are sessile organisms that rely on their ability to explore the soil to access the nutrients and water they need to survive. Plants have co-evolved with certain groups of bacteria and fungi that provide nutrients and water and enhance tolerance to abiotic and biotic stressors in exchange for Carbon (C). READ MORE
