Oxygen Isotope Composition Of Evapotranspiration And Its Relation To C4 Photosynthetic Discrimination
Griffis, T.J., Lee, X., Baker, J.M., Billmark, K., Erickson, N. Schultz,M., Zhang, X., Fassbinder, J., Xiao, W., Hu, N.

The oxygen isotope of water (18O-H2O) and carbon dioxide (18O-CO2) is an important signal of global change and can provide constraints on the coupled carbon-water cycle. Here, simultaneous observations of 18O-H2O (liquid and vapor phases) and 18O-CO2

Three-Dimensional Canopy Fuel Loading Predicted Using Upward And Downward Sensing LiDAR Systems
Skowronski, N. S., Clark, K. L., Duveneck, M., Hom, J.

We calibrated upward sensing profiling and downward sensing scanning LiDAR systems to estimates of canopy fuel loading developed from field plots and allometric equations, and then used the LiDAR datasets to predict canopy bulk density (CBD) and crown fuel weight (CFW) in wildfire prone stands in the New Jersey Pinelands. …

Large Greenhouse Gas Emissions From A Temperate Peatland Pasture
Teh, Y. A., Silver, W. L., Sonnentag, O., Detto, M., Kelly, M., Baldocchi, D. D.

Agricultural drainage is thought to alter greenhouse gas emissions from temperate peatlands, with CH4 emissions reduced in favor of greater CO2 losses. Attention has largely focussed on C trace gases, and less is known about the impacts …

Wildfire Reduces Carbon Dioxide Efflux And Increases Methane Uptake In Ponderosa Pine Forest Soils Of The Southwestern USA
Sullivan, B. W., Kolb, T. E., Hart, S. C., Kaye, J. P., Hungate, B. A., Dore, S., Montes-Helu, M.

Severe wildfire may cause long-term changes in the soil-atmosphere exchange of carbon dioxide and methane, two gases known to force atmospheric warming. We examined the effect of a severe wildfire 10 years after burning to determine decadal-scale changes in soil gas fluxes following fire, and explored mechanisms responsible for …

An Interannual Assessment Of The Relationship Between The Stable Carbon Isotopic Composition Of Ecosystem Respiration And Climate In A High-Elevation Subalpine Forest
Riveros-Iregui, D.A., Hu, J., Burns, S.P., Bowling, D.R., Monson, R.K.

We measured the carbon isotopic composition (δ13C) of ecosystem respiration (δ13CR) in a subalpine forest across four growing seasons to examine whether patterns in δ13CR were consistent with those expected based on leaf-level gas-exchange theory, …

Light-Stress Avoidance Mechanisms In A Sphagnum-Dominated Wet Coastal Arctic Tundra Ecosystem In Alaska
Zona, D., Oechel, W. C., Richards, J. H., Hastings, S., Kopetz, I., Ikawa, H., Oberbauer, S.

The Arctic experiences a high-radiation environment in the summer with 24-hour daylight for more than two months. Damage to plants and ecosystem metabolism can be muted by overcast conditions common in much of the Arctic. However, with climate change, extreme dry years and clearer skies could lead to the risk of increased photoxidation …

Improving Canopy Processes In The Community Land Model Version 4 (CLM4) Using Global Flux Fields Empirically Inferred From FLUXNET Data
Bonan, G.B., Lawrence, P.J., Oleson, K.W., Levis, S., Jung, M., Reichstein, M., Lawrence, D.M., Swenson, S.C.

The Community Land Model version 4 (CLM4) overestimates gross primary production (GPP) compared with data-driven estimates and other process models. We use global, spatially gridded GPP and latent heat flux …
