Carbon Dioxide Fluxes In Coastal Douglas-Fir Stands At Different Stages Of Development After Clearcut Harvesting
Humphreys, E. R., Black, T. A., Morgenstern, K., Cai, T., Drewitt, G. B., Nesic, Z., Trofymow, J.

Forests play a significant role in the global carbon (C) cycle. Variability in weather, species, stand age, and current and past disturbances are some of the factors that control stand-level C dynamics. This study examines the relative roles of stand age and associated structural …

Seasonality Of Photosynthetic Parameters In A Multi-Specific And Vertically Complex Forest Ecosystem In The Sierra Nevada Of California
Misson, L., Tu, K. P., Boniello, R. A., Goldstein, A. H.

Understanding seasonal variations of photosynthetic parameters is critical for accurate modeling of carbon dioxide (CO2) uptake by ecosystems. Maximum carboxylation velocity (Vcmax), maximum rate of electron transport (Jmax), leaf respiration in the light (Rday), …

Environmental Control Of Net Ecosystem Co2 Exchange In A Treed, Moderately Rich Fen In Northern Alberta
Syed, K. H., Flanagan, L. B., Carlson, P. J., Glenn, A. J., Van Gaalen, K. E.

Peatlands cover about 21% of the landscape and contain about 80% of the soil carbon stock in western Canada. However, the current rates of carbon accumulation and the environmental controls on ecosystem photosynthesis and respiration in peatland ecosystems are poorly understood. …

Environmental Controls Over Net Ecosystem Carbon Exchange Of Scrub Oak In Central Florida
Powell, T. L., Bracho, R., Li, J., Dore, S., Hinkle, C. R., Drake, B. G.

Biological and physical controls regulating variation of seasonal and interannual ecosystem carbon exchange in a scrub oak ecosystem in central Florida were determined by measuring net ecosystem exchange of CO2 (NEE) between the atmosphere and vegetation using …

Surface Energy And Carbon Dioxide Fluxes Above Different Vegetation Types Within ABLE
Coulter, R., Pekour, M., Cook, D., Klazura, G., Martin, T., Lucas, J.

Nineteen months of continuous data from two sites within the atmospheric boundary layer experiments (ABLE) facility are used to compare surface energy fluxes, carbon dioxide fluxes and controlling parameters. One site, which has been monitored continuously since 1997, is …

Ecosystem-Level CO2 Fluxes From A Boreal Cutover In Eastern Canada Before And After Scarification
Giasson, M., Coursolle, C., Margolis, H. A.

Carbon (C) cycling in the boreal forest is driven by both natural and human disturbances, but there is little information on the impact of forest management practices on ecosystem-level C balance. We evaluated the C balance of a recently harvested boreal site in eastern …

The Contribution Of Beneath-Snow Soil Respiration To Total Ecosystem Respiration In A High-Elevation, Subalpine Forest
Monson, R. K., Burns, S. P., Williams, M. W., Delany, A. C., Weintraub, M., Lipson, D. A.

The respiratory loss of CO2 from soil microbes beneath winter snow in forests from cold climates can significantly influence the annual carbon budget. We explored the magnitude of winter soil respiration using continuous measurements of beneath‐snow CO2 concentration within the footprint of a flux tower in a subalpine forest in …
