Journal: Global Change Biology, Volume 18 (10): 3171-3185 (2012), ISBN . DOI: 10.1111/j.1365-2486.2012.02775.x Sites: US-Fmf, US-Fuf, US-Fwf

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 Imprint Of Surface Fluxes And Transport On Variations In Total Column Carbon Dioxide

New observations of the vertically integrated CO2 mixing ratio, ⟨CO2⟩, from ground-based remote sensing show that variations in CO2⟩ are primarily determined by large-scale flux patterns. They therefore provide fundamentally different information than observations made …

Using Model-Data Fusion To Interpret Past Trends, And Quantify Uncertainties In Future Projections, Of Terrestrial Ecosystem Carbon Cycling
Keenan, T. F., Davidson, E., Moffat, A. M., Munger, W., Richardson, A. D.

Uncertainties in model projections of carbon cycling in terrestrial ecosystems stem from inaccurate parameterization of incorporated processes (endogenous uncertainties) and processes or drivers that are not accounted for by the model (exogenous uncertainties). Here, we assess endogenous and exogenous uncertainties using a model-data …

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 …

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 …

Five Years Of Carbon Fluxes And Inherent Water-Use Efficiency At Two Semi-Arid Pine Forests With Different Disturbance Histories
Vickers, D., Thomas, C., Pettijohn, C., Martin, J.G., Law, B.E.

Five years of eddy-covariance and other measurements at a mature ponderosa pine forest and a nearby young plantation are used to contrast the carbon fluxes for long-term averages, seasonal patterns, diel patterns and interannual variability, and to examine …

CO2 Fluxes Of A Boreal Black Spruce Chronosequence In Eastern North America
Payeur-Poirier, J., Coursolle, C., Margolis, H. A., Giasson, M.

Forest harvest and subsequent stand development can have major effects on the carbon cycle of boreal stands. Carbon dioxide (CO2) fluxes of a three-point black spruce harvest chronosequence located in the boreal forest of eastern North America were measured over a one-year period at the ecosystem scale with the eddy covariance …

Upscaling Of CO2 Fluxes From Heterogeneous Tundra Plant Communities In Arctic Alaska
Kade, A., Bret-Harte, M. S., Euskirchen, E. S., Edgar, C., Fulweber, R. A.

We characterized the tundra vegetation at three eddy covariance towers located along a toposequence in northern Alaska and studied seasonal variations in plot-level CO2 fluxes among the dominant vegetation types with chambers during the summer and with the gradient-diffusion technique during the winter. We performed footprint …

Seven-Year Trends Of CO2 Exchange In A Tundra Ecosystem Affected By Long-Term Permafrost Thaw
Trucco, C., Schuur, E. A., Natali, S. M., Belshe, E. F., Bracho, R., Vogel, J.

Arctic warming has led to permafrost degradation and ground subsidence, created as a result of ground ice melting. Frozen soil organic matter that thaws can increase carbon (C) emissions to the atmosphere, but this can be offset in part by increases in plant growth. The balance of plant and microbial processes, and how this balance …
