Climatic And Phenological Controls On Coherent Regional Interannual Variability Of Carbon Dioxide Flux In A Heterogeneous Landscape
Desai, A.R.

The climate sensitivity of plant seasonal life cycles, or phenology, may impart significant carbon cycle feedbacks on climatic change. Analysis of interannual ecosystem carbon exchange provides one way to assess this climate sensitivity. Multiyear eddy covariance carbon dioxide flux observations from five different ecosystems (deciduous …

CO2 Fluxes At Northern Fens And Bogs Have Opposite Responses To Inter-Annual Fluctuations In Water Table
Sulman, B. N., Desai, A. R., Saliendra, N. Z., Lafleur, P. M., Flanagan, L. B., Sonnentag, O., Mackay, D. S., Barr, A. G., van der Kamp, G.

This study compares eddy-covariance measurements of carbon dioxide fluxes at six northern temperate and boreal peatland sites in Canada and the northern United States of America, representing both bogs and fens. The two peatland types had opposite responses of gross ecosystem photosynthesis (GEP) and ecosystem respiration (ER) to …

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 …

Using Watershed Water Balance To Evaluate The Accuracy Of Eddy Covariance Evaporation Measurements For Three Semiarid Ecosystems
Scott, R. L.

The eddy covariance technique is a widely used and accepted method to quantify ecosystem-scale mass and energy fluxes. Eddy covariance measurements of evaporation, also known as evapotranspiration, are used to determine local, regional and global water budgets, calibrate …

Age Effects On Carbon Fluxes In Temperate Pine Forests
Peichl, M., Arain, M. A., Brodeur, J. J.

This study evaluates age-related patterns of ecosystem carbon (C) fluxes in a chronosequence (5-, 18-, 33-, and 68-year old in 2007) of planted pine (Pinus strobus L.) forests in southern Ontario, Canada, from 2003 to 2007. Carbon fluxes determined with the eddy covariance technique were normalized by differences in site …

Relative Contributions Of Soil, Foliar, And Woody Tissue Respiration To Total Ecosystem Respiration In Four Pine Forests Of Different Ages
Khomik, M., Arain, M. A., Brodeur, J. J., Peichl, M., Restrepo-Coupé, N., McLaren, J. D.

Carbon dioxide (CO2) emissions from soil, foliage, and live woody tissue were measured throughout the year in afforested, white pine (Pinus strobus L.) stands (67, 32, 17, and 4 years old as of 2006), growing in a northern temperate climate. The data were used to estimate annual ecosystem respiration (Re) …

Climatic Controls Of Interannual Variability In Regional Carbon Fluxes From Top-Down And Bottom-Up Perspectives
Desai, A. R., Helliker, B. R., Moorcroft, P. R., Andrews, A. E., Berry, J. A.

Observations of regional net ecosystem exchange (NEE) of CO2 for 1997–2007 were analyzed for climatic controls on interannual variability (IAV). Quantifying IAV of regional (104–106 km2) NEE over long time periods is key to understanding potential feedbacks between climate and the carbon …

Runoff And Erosional Responses To A Drought-Induced Shift In A Desert Grassland Community Composition
Polyakov, V.O., Nearing, M.A., Stone, J.J., Hamerlynck, E.P., Nichols, M.H., Holifield Collins, C.D., Scott, R.L.

This study investigates how drought-induced change in semiarid grassland community affected runoff and sediment yield in a small watershed in southeast Arizona, USA. Three distinct periods in ecosystem composition and associated runoff and sediment yield were identified according to dominant species: native bunchgrass (1974–2005), …
