Abstract

To improve predictions of ecosystem function under future environments we need to integrate the ecological and environmental histories experienced by microbial communities with hydrobiogeochemistry across scales. A key question is whether we can derive generalizable scaling relationships that describe this multiscale integration. There is a strong foundation for addressing these challenges. We have the ability to infer ecological history with null models and reveal impacts of environmental history through lab and field experimentation. Recent developments also provide opportunities to inform ecosystem models with targeted –omics data. A major next step is coupling knowledge derived from such studies with multiscale modeling frameworks that are predictive for non-steady state conditions. This is particularly true for systems spanning dynamic interfaces, which are often hotspots of hydrobiogeochemical function. We can advance predictive capabilities through a holistic perspective focused on the nexus of history, ecology, and hydrobiogeochemistry.
