  1. 1. The hidden half of the meadow : Interactions between drought, soil carbon, roots and soil microbial communities

    Författare :Daniela Guasconi; Gustaf Hugelius; Sara Cousins; Stefano Manzoni; Petra Fransson; David Johnson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; soil; soil carbon; soil ecology; roots; root traits; microbial communities; grasslands; climate change; drought; land management; compost; naturgeografi; Physical Geography;

    Sammanfattning : Soil is a hidden ecosystem which harbours plant roots and countless microorganisms, vital for sustaining life aboveground. These belowground communities provide essential ecosystem services like soil stabilisation and organic matter decomposition. LÄS MER

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

    Författare :Pil Uthaug Rasmussen; Ayco J. M. Tack; Martijn Bezemer; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. Diversity of soil microbial communities: In the perspective of targeting functional genes

    Författare :Lokeshwaran Manoharan; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Soil; metagenomics; sequence capture; microbial communities; functional diversity; taxonomic diversity;

    Sammanfattning : Abstract Intensive land use in agriculture can lead to higher loss of biodiversity in soils and subsequently carbon due to tillage and application of pesticides and fertilizers. The microbial communities are pivotal to ecosystem processes in soil such as nutrient cycling, soil formation and plant productivity and thus are affected by land use. LÄS MER

  5. 4. Drivers of soil fungal communities in boreal forests : feedbacks on soil fertility and decomposition

    Författare :Erica Sterkenburg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Boreal forests harbour diverse fungal communities with decisive roles in decomposition and plant nutrition. Difficulties in studying soil fungi have limited knowledge about how fungal communities are shaped. LÄS MER

  7. 5. Soil salinity as a driver of microbial community structure and functioning

    Författare :Kristin Rath; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Soil salinization; Soil Microbiology; soil microbial community; Bacteria; Aerobic; Fungi; Drying-rewetting; Microbial growth; Microbial biomass; Soil respiration; salinity tolerance; Saline soils; Salinity gradient;

    Sammanfattning : Soil salinization is a pressing agricultural problem in many areas of the world, particularly in areas heavily reliant on irrigation agriculture. While the negative effects of salinity on crop plants have been widely studied, its effects on soil microorganisms have received less attention, and the impact of soil salinity on both microbial community structure and functioning is not well understood.
