Soil microbial communities and global change

December 31, 2019

Soils and soil microbial communities mediate the biogeochemical processes that underly ecosystem-level changes. This chapter examines why soils and soil microbial communities are important for understanding impacts and feedbacks to global change. It discusses the technological approaches and challenges that are at the frontiers of this research area. Global change impacts on microbial communities can be categorized as press or pulse disturbances. Global increases in atmospheric temperature are among the most profound and concerning long-term changes affecting human society. The chapter focuses on the examples from Western North America, where issues such as land cover change, wildfire, and permafrost thaw are some of the most observable global change impacts. Wildfire is a natural phenomenon that lies at the basis of the process of plant succession. Recovery and regrowth of vegetation after wildfire regenerates carbon and nutrient pools, such that long-term impacts on the ecosystems may be small.
