21. The influence of soil structure on microbial processes in microfluidic models
Abstract : The way microbes behave in nature can vary widely depending on the spatial characteristics of the habitats they are located in. The spatial structure of the microbial environment can determine whether and to which extent processes such as organic matter degradation, and synergistic or antagonistic microbial processes occur.

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

23. Denitrification: from genes to ecosystems
Abstract : Denitrification is a part of the global nitrogen cycle in which fixed nitrogen in the biosphere is returned to the atmosphere, which is mediated by diverse communities of microorganisms. This thesis seeks to gain a greater understanding of the ecology of denitrifying microorganisms by examining the pathway from four different aspects; gene, population, community, and ecosystem.

24. Tracking the fate of biocontrol microorganisms in the environment using intrinsic SCAR markers
Abstract : Biocontrol microorganisms can be used as an alternative to conventional chemical pesticides to control plant diseases. This thesis investigated the fate and behaviour of three microbial model control agents with effect against fungal pathogens in cropping systems, and the spread of one of the model strains in bioaerosols.

25. Functional ecology of ectomycorrhizal fungi : peroxidases, decomposition, spatial community patterns
Abstract : Boreal forest ecosystems constitute a globally important carbon (C) sink, due to accumulation of complex organic matter, persistent to decomposition. Nitrogen (N) is immobilized in these complex compounds and, thereby, unavailable to the plant community. READ MORE
