A Comparison Of Three Methods To Estimate Evapotranspiration In Two Contrasting Loblolly Pine Plantations: Age-Related Changes In Water Use And Drought Sensitivity Of Evapotranspiration Components
Domec, J., Sun, G., Noormets, A., Gavazzi, M. J., Treasure, E. A., Cohen, E., Swenson, J. J., McNulty, S. G., King, J. S.

Increasing variability of rainfall patterns requires detailed understanding of the pathways of water loss from ecosystems to optimize carbon uptake and management choices. In the current study we characterized the usability of three alternative methods of different rigor for quantifying stand-level evapotranspiration (ET), partitioned …

Interactive Effects Of Nocturnal Transpiration And Climate Change On The Root Hydraulic Redistribution And Carbon And Water Budgets Of Southern United States Pine Plantations
Domec, J., Ogee, J., Noormets, A., Jouangy, J., Gavazzi, M., Treasure, E., Sun, G., McNulty, S. G., King, J. S.

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, …

The Role Of Harvest Residue In Rotation Cycle Carbon Balance In Loblolly Pine Plantations. Respiration Partitioning Approach
Noormets, A., McNulty, S. G., Domec, J., Gavazzi, M., Sun, G., King, J. S.

Timber harvests remove a significant portion of ecosystem carbon. While some of the wood products moved off-site may last past the harvest cycle of the particular forest crop, the effect of the episodic disturbances …

Response Of Carbon Fluxes To Drought In A Coastal Plain Loblolly Pine Forest
Noormets, A., Gavazzi, M. J., Mcnulty, S. G., Domec, J., Sun, G., King, J. S., Chen, J.

Full accounting of ecosystem carbon (C) pools and fluxes in coastal plain ecosystems remains less studied compared with upland systems, even though the C stocks in these systems …

Energy And Water Balance Of Two Contrasting Loblolly Pine Plantations On The Lower Coastal Plain Of North Carolina, USA
Sun, G., Noormets, A., Gavazzi, M., McNulty, S., Chen, J., Domec, J., King, J., Amatya, D., Skaggs, R.

During 2005–2007, we used the eddy covariance and associated hydrometric methods to construct energy and water budgets along a chronosequence of loblolly pine (Pinus taeda) plantations that included a mid-rotation stand (LP) (i.e., 13–15 years old) and a recently established stand on a clearcut site (CC) (i.e., 4–6 …

Hydraulic Redistribution Of Soil Water By Roots Affects Whole-Stand Evapotranspiration And Net Ecosystem Carbon Exchange
Domec, J., King, J. S., Noormets, A., Treasure, E., Gavazzi, M. J., Sun, G., McNulty, S. G.
  • Hydraulic redistribution (HR) of water via roots from moist to drier portions of the soil occurs in many ecosystems, potentially influencing both water use and carbon assimilation.
  • By measuring soil water content, sap flow and eddy covariance, we investigated the temporal variability of …
