Integration Of CO2 Flux And Remotely-Sensed Data For Primary Production And Ecosystem Respiration Analyses In The Northern Great Plains: Potential For Quantitative Spatial Extrapolation
Gilmanov, T. G., Tieszen, L. L., Wylie, B. K., Flanagan, L. B., Frank, A. B., Haferkamp, M. R., Meyers, T. P., Morgan, J. A.

Aim  Extrapolation of tower CO2 fluxes will be greatly facilitated if robust relationships between flux components and remotely sensed factors are established. Long-term measurements at five Northern Great Plains locations were used to obtain relationships between CO2 fluxes and photosynthetically active …

Climate Impact On Net Ecosystem Productivity Of A Semi-Arid Natural Grassland: Modeling And Measurement
Li, T., Grant, R. F., Flanagan, L. B.

Models used to estimate net ecosystem productivity (NEP) during climate change should first be shown to simulate the effects on NEP of interannual variability in current climates. Energy and CO2 fluxes simulated by the ecosystem model ecosys were compared …

Molecular And Carbon Isotopic Composition Of Leaf Wax In Vegetation And Aerosols In A Northern Prairie Ecosystem
Conte, M. H., Weber, J. C., Carlson, P. J., Flanagan, L. B.

We measured the molecular and carbon isotopic composition of major leaf wax compound classes in northern mixed mesic prairie species (Agropyron smithii, Stipa viridula, Bouteloua gracilis,

Seasonal And Interannual Variation In Carbon Dioxide Exchange And Carbon Balance In A Northern Temperate Grassland
Flanagan, L. B., Wever, L. A., Carlson, P. J.

Net ecosystem carbon dioxide (CO2) exchange (NEE) was measured in a northern temperate grassland near Lethbridge, Alberta, Canada for three growing seasons using the eddy covariance technique. The study objectives were to document how NEE and its major component processes—gross photosynthesis (GPP) and total ecosystem …

Spatial And Temporal Variation In The Carbon And Oxygen Stable Isotope Ratio Of Respired CO2 In A Boreal Forest Ecosystem
Flanagan, L. B., Kubien, D. S., Ehleringer, J. R.

We measured the stable isotope ratio of respired carbon dioxide at two spatial scales in a black spruce forest in northern Canada: CO2 released from the forest floor and CO2 released from the entire ecosystem at night. Despite wide variation in the δ13C values of organic matter among above-ground plant species, …

Carbon Isotope Discrimination During Photosynthesis And The Isotope Ratio Of Respired CO2 in Boreal Forest Ecosystems
Flanagan, L. B., Brooks, J. R., Varney, G. T., Berry, S. C., Ehleringer, J. R.

Our objective was to measure the carbon isotope ratio of CO2 released by respiration (δr) within forest canopies at different times during the growing season and to use this information to estimate forest ecosystem carbon isotope discrimination. We made measurements in the three major forest types (black spruce, …
