Microorganisms inhabit all biomes on Earth where they perform critical functions such as maintaining the biogeochemical cycling necessary for plant productivity and increasing organismal stress tolerance. Microbial effects can extend across ecological, spatial, and temporal scales to impact plant invasions, plant succession, and even ecosystem carbon feedback to the atmosphere. Yet we have limited knowledge on patterns and key drivers of microbial distributions especially at continental to global scales. This knowledge gap precludes us from understanding simple rules of life that apply to other “macro” organisms. For example, ”How big are microbial species ranges?”, “How many microbial environmental or host generalist versus specialist taxa exist?”, “Does environmental tolerance, competition, or dispersal limitation structure microbial distributions?”. Understanding these fundamental processes will resolve hotspots of current and future microbial biodiversity and function, provide information on distributions of microbial mutualists and pathogens, and lead to informed applications of microbial inocula to increase crop yields or sequester soil carbon. In addition, these are the types of questions that must be answered before microbial community composition can be predictive of ecosystem function. The research presented in the proposed symposium will appeal to a broad audience of ESA members as it (1) synthesizes multiple disciplines (macro, organismal, community, and ecosystem ecology), (2) defines rules of life that apply to macro and microorganisms, and (3) integrates microorganisms into frameworks to explain plant composition and ecosystem dynamics.
