Production, Respiration, And Overall Carbon Balance In An Old-Growth Pseudotsuga-Tsuga Forest Ecosystem
Harmon, M.E., Bible, K., Ryan, M.G., Shaw, D.C., Chen, H., Klopatek, J., Li, X.

Ground-based measurements of stores, growth, mortality, litterfall, respiration, and decomposition were conducted in an old-growth forest at Wind River Experimental Forest, Washington, USA. These measurements were used to estimate gross primary production (GPP) and net primary production (NPP); autotrophic respiration (Ra) …

Dynamics Of Carbon Stocks In Soils And Detritus Across Chronosequences Of Different Forest Types In The Pacific Northwest, USA
Sun, O. J., Campbell, J., Law, B. E., Wolf, V.

We investigated variation in carbon stock in soils and detritus (forest floor and woody debris) in chronosequences that represent the range of forest types in the US Pacific Northwest. Stands range in age from <13 to >600 years. Soil carbon, to a depth of 100 cm, was highest in coastal Sitka spruce/western hemlock forests …

Limitations To Carbon Mineralization In Litter And Mineral Soil Of Young And Old Ponderosa Pine Forests
Kelliher, F., Ross, D., Law, B., Baldocchi, D., Rodda, N.

Summer drought is a feature of the semi-arid region of central Oregon, USA, where vegetation naturally develops into ponderosa pine (Pinus ponderosa var. Laws) forest. Forest management consists of clearcut harvest and natural regeneration. Soil microbial activity …

Respiration From A Tropical Forest Ecosystem: Partitioning Of Sources And Low Carbon Use Efficiency
Chambers, J. Q., Tribuzy, E. S., Toledo, L. C., Crispim, B. F., Higuchi, N., Santos, J. d., Araújo, A. C., Kruijt, B., Nobre, A. D., Trumbore, S. E.

Understanding how tropical forest carbon balance will respond to global change requires knowledge of individual heterotrophic and autotrophic respiratory sources, together with factors that control respiratory …

A Global Relationship Between The Heterotrophic And Autotrophic Components Of Soil Respiration?
Bond-Lamberty, B., Wang, C., Gower, S. T.

Soil surface CO2 flux (RS) is overwhelmingly the product of respiration by roots (autotrophic respiration, RA) and soil organisms (heterotrophic respiration, RH). Many studies have attempted to partition RS into these two components, with highly …

Spatial And Temporal Variability In Forest-Atmosphere CO2 Exchange
Hollinger, D. Y., Aber, J., Dail, B., Davidson, E. A., Goltz, S. M., Hughes, H., Leclerc, M. Y., Lee, J. T., Richardson, A. D., Rodrigues, C., Scott, N., Achuatavarier, D., Walsh, J.

Seven years of carbon dioxide flux measurements indicate that a ∼90-year-old spruce dominated forest in Maine, USA, has been sequestering 174±46 g C m−2 yr−1 (mean±1 standard deviation, nocturnal friction velocity (u*) threshold >0.25 m s−1). An analysis of monthly …

Remote Measurement Of Energy And Carbon Flux From Wildfires In Brazil
Riggan, P. J., Tissell, R. G., Lockwood, R. N., Brass, J. A., Pereira, J. A., Miranda, H. S., Miranda, A. C., Campos, T., Higgins, R.

Temperature, intensity, spread, and dimensions of fires burning in tropical savanna and slashed tropical forest in central Brazil were measured for the first time by remote sensing with an infrared imaging spectrometer that was designed to accommodate the high radiances of wildland fires. Furthermore, the first in situ airborne measurements …

Component And Whole-System Respiration Fluxes In Northern Deciduous Forests
Bolstad, P. V., Davis, K. J., Martin, J., Cook, B. D., Wang, W.

We measured component and whole-system respiration fluxes in northern hardwood (Acer saccharumMarsh., Tilia americana L., Fraxinus pennsylvanica Marsh.) and aspen (Populus tremuloides Michx.) forest stands in Price County, northern Wisconsin from 1999 through 2002. Measurements of soil, leaf and …

Respiratory Carbon Use And Carbon Storage In Mid-Rotation Loblolly Pine (Pinus Taeda L.) Plantations: The Effect Of Site Resources On The Stand Carbon Balance
Maier, C. A., Albaugh, T. J., Allen, H. L., Dougherty, P. M.

We used estimates of autotrophic respiration (RA), net primary productivity (NPP) and soil CO2 evolution (Sff), to develop component carbon budgets for 12-year-old loblolly pine plantations during the fifth year of a fertilization and irrigation experiment. Annual carbon use in RA
