Abstract
Microbial regulation of global biogeochemical cycles.
Highlights
Global biogeochemical cycles of carbon and other nutrients are increasingly affected by human activities (Griggs et al, 2013)
The rate of organic matter degradation in a soil is determined by both the indigenous microbial community and the environmental conditions, which govern the biogeochemical activities of the microorganisms (Waksman and Gerretsen, 1931; Schmidt et al, 2011)
By determining how different groups of microorganisms respond to individual environmental conditions by allocating e.g. carbon to production of biomass, CO2 and other products, a mechanistic as well as quantitative understanding of formation and decomposition of organic matter, and the production and consumption of greenhouse gases, can be achieved. In this Research Topic, supported by the Swedish research councils’ program “Biodiversity and Ecosystem Services in a Changing Landscape” (BECC), we intend to promote an alternative framework to address how cycling of carbon and other nutrients will be altered in a changing environment from the first-principle mechanisms that drive them—namely the ecology, physiology and biogeography of microorganisms
Summary
Global biogeochemical cycles of carbon and other nutrients are increasingly affected by human activities (Griggs et al, 2013). The rate of organic matter degradation in a soil is determined by both the indigenous microbial community and the environmental conditions (e.g., temperature, pH, soil water capacity, etc.), which govern the biogeochemical activities of the microorganisms (Waksman and Gerretsen, 1931; Schmidt et al, 2011).
