• Hydrologic connections can link hillslopes to channel networks, streams to lakes, subsurface to surface, land to atmosphere, terrestrial to aquatic, and upstream to downstream. These connections can develop across vertical, lateral, and longitudinal dimensions and span spatial and temporal scales. Each of these dimensions and scales are interconnected, creating a mosaic of nested hydrologic connections and associated processes. In turn, these interacting and nested processes influence the transport, cycling, and transformation of organic material and inorganic nutrients through watersheds and along fluvial networks. Although hydrologic connections span dimensions and spatiotemporal scales, relationships between connectivity and carbon and nutrient dynamics are rarely evaluated within this framework. The purpose of this paper is to provide a cross-disciplinary view of hydrologic connectivity — highlighting the various forms of hydrologic connectivity that control fluxes of organic material and nutrients — and to help stimulate integration across scales and dimensions, and collaboration among disciplines. •Hydrologic connections span numerous spatial dimensions and spatiotemporal scales creating a mosaic of nested processes•These nested processes influence organic carbon and inorganic nutrient transport through watersheds and fluvial networks•Human activity has altered hydrologic connectivity and nutrient dynamics along each of the spatial dimensions of connectivity•Collaboration and integration are necessary to unravel relationships between connectivity and biogeochemical dynamics
