Seasonal Variability Of Forest Sensitivity To Heat And Drought Stresses: A Synthesis Based On Carbon Fluxes From North American Forest Ecosystems
Xu, B., Arain, M. A., Black, T. A., Law, B. E., Pastorello, G. Z., Chu, H.

Climate extremes such as heat waves and droughts are projected to occur more Frequently with increasing temperature and an intensified hydrological cycle. It is Important to understand and quantify how forest carbon fluxes respond to heat and drought stress. In this study, we developed a series of daily indices of sensitivity to …

Influence Of Stand Age On The Magnitude And Seasonality Of Carbon Fluxes In Canadian Forests
Coursolle, C., Margolis, H., Giasson, M., Bernier, P., Amiro, B., Arain, M., Barr, A., Black, T., Goulden, M., McCaughey, J., Chen, J., Dunn, A., Grant, R., Lafleur, P.

Proper management and accounting of forest carbon requires good knowledge of how disturbances and climate affect the carbon dynamics of different stand types. We have investigated such relationships by measuring, over a 5-year period (2003–2007), the net ecosystem productivity (NEP), gross ecosystem productivity …

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 …

Carbon Dioxide, Methane, And Nitrous Oxide Exchanges In An Age-Sequence Of Temperate Pine Forests
Peichl, M., Arain, M.A., Ullah, S., Moore, T.

We investigated soil carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) exchanges in an age-sequence (4, 17, 32, 67 years old) of …

Biometric And Eddy-Covariance Based Estimates Of Carbon Fluxes In An Age-Sequence Of Temperate Pine Forests
Peichl, M., Brodeur, J. J., Khomik, M., Arain, M. A.

We present four years (2005–2008) of biometric (B) and eddy-covariance (EC) measurements of carbon (C) fluxes to constrain estimates of gross primary production (GPP), net primary production (NPP), ecosystem respiration (RE) and net ecosystem production (NEP) in an age-sequence (6-, 19-, 34-, and 69-years-old in 2008) of pine forests …

Relative Contributions Of Soil, Foliar, And Woody Tissue Respiration To Total Ecosystem Respiration In Four Pine Forests Of Different Ages
Khomik, M., Arain, A.M., 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) …

Debut Of A Flexible Model For Simulating Soil Respiration–Soil Temperature Relationship: Gamma Model
Khomik M., Arain A. M.: Liaw K. L., McCaughey H. J.

A number of empirical models are used in literature to simulate the response of soil respiration (Rs) to soil temperature (Ts). The most widely used ones are the exponential Q10 model and the sigmoid-shaped Lloyd-Taylor and logistic models. None of these models are applicable across a wide range of ecosystems or climates, and none …

Allometry And Partitioning Of Above- And Belowground Tree Biomass In An Age-Sequence Of White Pine Forests
Peichl, M., Arain, M. A.

The allometry and partitioning of above- and belowground tree biomass was studied in an age-sequence of four eastern white pine (Pinus strobus L.) forests (2-, 15-, 30-, and 65-year-old) in southern Ontario, Canada. Biomass in each tree component, i.e. foliage, …
