1. 1. 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.

3. 2. 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

5. 4. Pollution-Induced Community Tolerance (PICT) of Bacteria: Evaluation in Phenol- and Antibiotic Polluted Soil

   Författare :Louise Aldén; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Antibiotics; Bacteria; Community; Fungi; Leucine incorporation; Phenols; Soil; Pollution-Induced Community Tolerance PICT ;

   Sammanfattning : The effects of organic pollutants on the soil microbial community were studied in this work. The main aim was to evaluate the use of pollution-induced community tolerance (PICT) in studying the effects of pollution. The leucine incorporation technique (indicating bacterial growth) was used to monitor changes in tolerance. 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
