OOS 73 - Root Dynamics in a Changing World: Deep and Dark Effects on Ecosystem Function

Amanda Longhi Cordeiro and Lee H. Dietterich
Roots and their growth, activity, and turnover represent a fundamentally important but poorly understood component of ecosystem function. Globally, all terrestrial biomes are facing multiple global change factors, from climate change to nitrogen deposition to land use and land cover change. The response of root dynamics to global change is of particular importance. Roots represent the primary input of new C to subsurface soils, which represent the largest stocks of C on Earth. Roots also play major roles in the cycling of nutrients, and root dynamics may shape plant-plant interactions and belowground food webs. This Organized Oral Session will explore advances in our understanding of how root dynamics respond to, feedback to, and/or adapt to global change across terrestrial ecosystems, with implications for altered ecosystem function in a changing world.
