An Evaluation Of Models For Partitioning Eddy Covariance-Measured Net Ecosystem Exchange Into Photosynthesis And Respiration
Stoy, P. C., Katul, G. G., Siqueira, M. B., Juang, J., Novick, K. A., Uebelherr, J. M., Oren, R.

We measured net ecosystem CO2 exchange (NEE) using the eddy covariance (EC) technique for 4 years at adjoining old field (OF), planted pine (PP) and hardwood forest (HW) ecosystems in the Duke Forest, NC. To compute annual sums of NEE and its components – gross …

Influences Of Canopy Photosynthesis And Summer Rain Pulses On Root Dynamics And Soil Respiration In A Young Ponderosa Pine Forest
Misson, L., Gershenson, A., Tang, J., McKay, M., Cheng, W., Goldstein, A.
Our first objective was to link the seasonality of fine root dynamics with soil respiration in a ponderosa pine (Pinus ponderosa P. & C. Lawson) plantation located in the Sierra Nevada of California. The second objective was to examine how canopy photosynthesis influences fine root initiation, …

An Eddy Covariance Mesonet To Measure The Effect Of Forest Age On Land-Atmosphere Exchange
Goulden, M. L., Winston, G. C., McMillan, A. M., Litvak, M. E., Read, E. L., Rocha, A. V., Rob Elliot, J.

We deployed a mesonet of year-round eddy covariance towers in boreal forest stands that last burned in ∼1850, ∼1930, 1964, 1981, 1989, 1998, and 2003 to understand how CO2 exchange and evapotranspiration change during secondary succession. We used MODIS imagery to establish that the tower sites were representative …

Model-Data Synthesis Of Diurnal And Seasonal CO2 Fluxes At Niwot Ridge, Colorado
Sacks, W. J., Schimel, D. S., Monson, R. K., Braswell, B. H.

Eddy covariance records hold great promise for understanding the processes controlling the net ecosystem exchange of CO2 (NEE). However, NEE is the small difference …

Winter Forest Soil Respiration Controlled By Climate And Microbial Community Composition
Monson, R. K., Lipson, D. L., Burns, S. P., Turnipseed, A. A., Delany, A. C., Williams, M. W., Schmidt, S. K.

Most terrestrial carbon sequestration at mid-latitudes in the Northern Hemisphere occurs in seasonal, montane forest ecosystems1. Winter respiratory carbon dioxide losses from these ecosystems are high, and over half of the carbon assimilated by photosynthesis in the summer can be lost the following winter2,3. The amount of winter …

Partitioning Of Evapotranspiration And Its Relation To Carbon Dioxide Exchange In A Chihuahuan Desert Shrubland
Scott, R. L., Huxman, T. E., Cable, W. L., Emmerich, W. E.

Key to evaluating the consequences of woody plant encroachment on water and carbon cycling in semiarid ecosystems is a mechanistic understanding of how biological and non-biological processes influence water loss to the atmosphere. To better understand how precipitation is partitioned into the components of evapotranspiration (bare-soil …

Measuring Canopy Structure And The Kinematics Of Subcanopy Flows In Two Forests
Staebler, R. M., Fitzjarrald, D. R.

A better understanding of forest subcanopy flows is needed to evaluate their role in the horizontal movement of scalars, particularly in complex terrain. This paper describes detailed measurements of the canopy structure and its variability in both the horizontal …
