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 …

Seasonal Variation And Partitioning Of Ecosystem Respiration In A Southern Boreal Aspen Forest
Griffis, T., Black, T., Gaumont-Guay, D., Drewitt, G., Nesic, Z., Barr, A., Morgenstern, K., Kljun, N.

Continuous automatic chamber and eddy covariance (EC) measurements were made at an old aspen forest (SOA) located at southern boreal treeline in Saskatchewan, Canada to examine the temporal variability in soil (Rs), tree bole (Rb), and ecosystem respiration (RE) during 2001. …

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

Forest Thinning Experiment Confirms Ozone Deposition To Forest Canopy Is Dominated By Reaction With Biogenic VOCs
Goldstein, A. H., McKay, M., Kurpius, M. R., Schade, G. W., Lee, A., Holzinger, R., Rasmussen, R. A.

Ecosystem ozone uptake can occur through stomatal and surface deposition and through gas phase chemical reactions. In a California pine forest, thinning dramatically enhanced both monoterpene emission and ozone uptake. These simultaneous enhancements provide strong evidence that ozone reactions with unmeasured biogenically emitted …

Hybrid-Maize—A Maize Simulation Model That Combines Two Crop Modeling Approaches
Yang, H., Dobermann, A., Lindquist, J., Walters, D., Arkebauer, T., Cassman, K.

A new maize (Zea mays L.) simulation model, Hybrid-Maize, was developed by combining the strengths of two modeling approaches: the growth and development functions in maize-specific models represented by CERES-Maize, and the mechanistic formulation of photosynthesis and respiration in generic crop models such as INTERCOM …

Growing Season Carbon Dioxide Exchange In Irrigated And Rainfed Maize
Suyker, A., Verma, S., Burba, G., Arkebauer, T., Walters, D., Hubbard, K.

Net ecosystem CO2 exchange (NEE) was measured in maize-based agroecosystems in eastern Nebraska, USA, during the growing season in 2001. The objective of this study was to quantify and contrast NEE in irrigated and rainfed maize (Zea maize L.) fields. …
