  1. 1. It's complicated: : The role of timing in microbial community coalescence

    Författare :Theresa Lumpi; Eva S. Lindström; Clara Ruiz-González; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; community coalescence; arrival timing; dispersal timing; microbial communities; community composition; lake bacteria; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Sammanfattning : In recent years, the importance of historical contingency has been increasingly recognized in microbial communities. During community coalescence, immigration history, and dispersal history can become decisive for the developing community. 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.

  5. 4. Microbial communities : descriptors of environmental change in marine ecosystems

    Författare :Li Zhao; Agneta Andersson; Xiao-Ru Wang; Alexander Eiler; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In northern marginal seas, like the northern Baltic Sea, climate change will lead to many alterations, for example increased inflows of nutrients and dissolved organic matter (DOM). Nutrients and DOM are fundamental drivers shaping marine microbial communities, including both bacterial and phytoplankton populations. LÄS MER

  7. 5. Microbial Community Assembly during Aerobic Granulation

    Författare :Raquel Liebana; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aerobic granular sludge; granulation; washout dynamics; membrane bioreactors; sequencing batch reactors; fluorescence in-situ hybridization; microbial community dynamics; reproducibility;

    Sammanfattning : Environmental deterioration together with the increasingly restrictive legislation of water quality standards have led to a demand for compact, efficient and less energy consuming technologies for wastewater treatment. Aerobic granular membrane bioreactors (AGMBRs) combine the advantages of aerobic granular sludge and membrane filtration. LÄS MER
