The Canopy Underground: Convergence of the Effect of Root Hydraulic Functioning and Root Hydraulic Redistribution on Ecosystem Carbon Balance Across Divergent Loblolly Pine Forests PDF document: PINEMAP Research Summary, November 2012. Authors: Jean-Christophe Domec, Jérôme Ogée, Asko Noormets, Julien Jouangy, Michael Gavazzi, Emrys Treasure, Ge Sun, Steve McNulty, and John S. King. Deep root water uptake and hydraulic redistribution (HR) have been shown to play a major role in forest ecosystems during drought, but little is known about the impact of climate change, fertilization, and soil characteristics on HR and its consequences on water and carbon fluxes. Using data from three mid-rotation loblolly pine plantations and simulations with the process-based model MuSICA, this study indicated that HR can mitigate the effects of soil drying and had important implications for carbon uptake potential and net ecosystem exchange (NEE), especially when N fertilization is considered.
