  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. 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.

  4. 3. Microbial Communities in Boreal Peatlands : Responses to Climate Change and Atmospheric Nitrogen and Sulfur Depositions

    Författare :Magalí Martí Genero; Bo Svensson; Åsa Danielsson; Torben Christensen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Microbial communities; methanogens; plant communities; peatland; temperature; nitrogen; long-term; field experiment; high-throughput sequencing; Microbiella samhällen; metanogener; växtsamhällen; myrar; torv; temperatur; kväve; långtid; fältexperiment; high-throughput-sekvensering;

    Sammanfattning : Myrmarker har en stor roll i regleringen av den globala kolbalansen och koncentrationerna av koldioxid och metan i atmosfären, vilket gör dem till speciellt viktiga ekosystem ur ett klimatförandringsperspektiv. Förändringar av myrmarker genom naturlig utveckling eller antropogen påverkan kan därför få långtgående störningar av myrars klimatreglerande funktion. LÄS MER

  5. 4. 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

  7. 5. Microbial temperature dependences in soil: The belowground feedback to climate change

    Författare :Dániel Tájmel; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; soil microbial community; microbial growth; microbial respiration; temperature dependence; climate change;

    Sammanfattning : Since the Industrial Revolution, human activities have elevated atmospheric CO2 concentrations. The consequences of this include rising temperatures, shifts in precipitation patterns, and increased intensity and frequency of extreme weather events, such as heat waves and droughts. LÄS MER
