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 …

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, …

How Climate And Vegetation Type Influence Evapotranspiration And Water Use Efficiency In Canadian Forest, Peatland And Grassland Ecosystems
Brümmer, C., Black, T. A., Jassal, R. S., Grant, N. J., Spittlehouse, D. L., Chen, B., Nesic, Z., Amiro, B. D., Arain, M. A., Barr, A. G., Bourque, C. P., Coursolle, C., Dunn, A. L., Flanagan, L. B., Humphreys, E. R., Lafleur, P. M., Margolis, H. A., McCaughey, J. H., Wofsy, S. C.

The effects of climatic factors and vegetation type on evapotranspiration (E) and water use efficiency (WUE) were analyzed using tower-based eddy-covariance (EC) data for nine mature forest sites, two peatland sites and one grassland site across an east–west …

Evidence Of Increased Net Ecosystem Productivity Associated With A Longer Vegetated Season In A Deciduous Forest In South-Central Indiana, Usa
DRAGONI, D., SCHMID, H. P., WAYSON, C. A., POTTER, H., GRIMMOND, C. S., RANDOLPH, J. C.

Observations of net ecosystem exchange (NEE) of carbon and its biophysical drivers have been collected at the AmeriFlux site in the Morgan-Monroe State Forest (MMSF) in Indiana, USA since 1998. Thus, this is one of the few deciduous forest sites in the world, where a decadal analysis on net ecosystem productivity (NEP) trends is …

Seasonal Pattern Of Regional Carbon Balance In The Central Rocky Mountains From Surface And Airborne Measurements
Desai, A.R., Moore, D.J.P., Ahue, W.K.M., Wilkes, P.T.V., De Wekker, S.F.J., Brooks, B.G., Campos, T.L., Stephens, B.B., Monson, R.K., Burns, S.P., Quaife, T., Aulenbach, S.M., Schimel, D.S.

High-elevation forests represent a large fraction of potential carbon uptake in North America, but this uptake is not well constrained by observations. Additionally, forests in the Rocky Mountains have recently been severely damaged by drought, fire, and insect outbreaks, which have been quantified at local scales but not assessed …

Disturbance And The Resilience Of Coupled Carbon And Nitrogen Cycling In A North Temperate Forest
Nave, L.E., Gough, C.M., Maurer, K.D., Bohrer, G, Hardiman, B.S., Le Moine, J., Munoz, A.B., Nadelhoffer, K.J., Sparks, J.P., Strahm, B.D., Vogel, C.S., Curtis, P.S.

Much of our biogeochemical understanding of forest disturbances comes from studies of severe or stand-replacing events, which may have different impacts on coupled carbon (C) and nitrogen (N) cycling than …

Comparing Laser-Based Open- And Closed-Path Gas Analyzers To Measure Methane Fluxes Using The Eddy Covariance Method
Detto, M., Verfaillie, J., Anderson, F., Xu, L., Baldocchi, D.

Closed- and open-path methane gas analyzers are used in eddy covariance systems to compare three potential methane emitting ecosystems in the Sacramento-San Joaquin Delta (CA, USA): a rice field, a peatland pasture and a restored wetland. The study points out similarities …

Sonnentag, O., Detto, M., Runkle, B. R. K., Teh, Y. A., Silver, W. L., Kelly, M., Baldocchi, D. D.

The net ecosystem carbon dioxide (CO2) exchange of invasive plant infestations, such as perennial pepperweed (Lepidium latifolium L.), is not well understood. A characteristic feature …

Characteristics Of The Flux Of Isoprene And Its Oxidation Products In An Urban Area
Park, C., Schade, G. W., Boedeker, I.

We measured the mixing ratios and fluxes of isoprene and its oxidation products, methacrolein (MACR) and methyl vinyl ketone (MVK) from a tall flux tower in metropolitan Houston, Texas, during summertime using a relaxed eddy accumulation (REA) system combined with a dual-channel GC-FID instrument. We show that isoprene was affected …
