  2. 1. Microbial communities : descriptors of environmental change in marine ecosystems

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

    Abstract : 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. READ MORE

  4. 2. Soil salinity as a driver of microbial community structure and functioning

    Author : Kristin Rath; MEMEG; []
    Keywords : 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;

    Abstract : 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.

    Abstract : Many factors can influence the rate of microbial degradation of organic contaminants in aquifers. Some of these factors, e.g. READ MORE

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

    Author : Theresa Lumpi; Eva S. Lindström; Clara Ruiz-González; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 5. Microbial communities in biological electrochemical systems

    Author : Marie Abadikhah; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; viruses; microbial ecology. microbial electrolysis cells; bioelectrochemical system; biocathode; bioanode; microbial community assembly;

    Abstract : Biological electrochemical systems (BES) can be used as biosensors and for recovery of resources from waste streams. BES utilizes microbial communities that grow on the surface of electrodes in the form of biofilms. READ MORE
