Global climate change, invasion by nonnative species, and loss of biodiversity are changing communities, ecosystem processes, and the ecosystem services they provide. Concurrently, new technologies are enabling our ability to study soil ecosystems and how belowground microbial diversity is critical for understanding long-studied aboveground ecosystem responses. This session will explore how global change drivers coupled with our understanding of plant-soil interactions are changing our expectations of how above- and belowground communities and ecosystems will look in the future. We then expand to include how we should adapt our management of these ecosystems to maintain biodiversity and critical ecosystem processes. This session will bring together researchers working across diverse ecosystems—dunes, dry grasslands, forests, prairies, and shrublands—and a diversity of approaches—from molecular-level to ecosystem-level and empirical to theoretical—to explore this topic. The session will be broadly divided into two main sections: First, we will bring together basic research addressing how climate change, invasive species, and the changing diversity of both above- and belowground organisms can alter expectations of how plants and soil organisms interact with one another and successional trajectories of these interactions. Second, we will shift our focus to how this enhanced understanding of global change and plant-soil feedbacks might alter our management and restoration efforts.
