The Land €“Atmosphere Water Flux In The Tropics
Fisher, J.B., Malhi, Y., Bonal, D., Rocha, H.R.D., Araújo, A.C.D., Gamo, M., Goulden, M.L., Hirano, T., Huete, A.R., Kondo, H., Kumagai, T., Loescher, H.W., Miller, S., Nobre, A.D., Nouvellon, Y., Oberbauer, S.F., Panuthai, S., Roupsard, O., Saleska, S., Tanaka, K., Tanaka, N., Tu, K.P., Randow, C.V.

Tropical vegetation is a major source of global land surface evapotranspiration, and can thus play a major role in global hydrological cycles and global atmospheric circulation. Accurate prediction of tropical evapotranspiration is critical to our understanding of these processes under changing climate. We examined the controls on …

Physiological Responses Of Red Mangroves To The Climate In The Florida Everglades
Barr, J. G., Fuentes, J. D., Engel, V., Zieman, J. C.

This manuscript reports the findings of physiological studies of red mangrove (Rhizophora mangle L.) conducted from June to August 2001 and from May to June 2003 in the Florida Everglades. In situ physiological measurements were made using environmentally controlled gas exchange systems. The field investigations were carried …

The Effect Of Permafrost Thaw On Old Carbon Release And Net Carbon Exchange From Tundra
Schuur, E. A., Vogel, J. G., Crummer, K. G., Lee, H., Sickman, J. O., Osterkamp, T. E.

Permafrost soils in boreal and Arctic ecosystems store almost twice as much carbon1, 2 as is currently present in the atmosphere

Persistent Effects Of Fire-Induced Vegetation Change On Energy Partitioning And Evapotranspiration In Ponderosa Pine Forests
Montes-Helu, M., Kolb, T., Dore, S., Sullivan, B., Hart, S., Koch, G., Hungate, B.

We compared energy fluxes between a site converted from ponderosa pine (Pinus ponderosa) forest to sparse grassland by a severe wildfire 10 years ago and a nearby, unburned forest. We used eddy covariance and associated instruments to measure total radiation, net radiation, albedo, and fluxes of energy into latent heat, …

Soil Evaporation Response To Lehmann Lovegrass (Eragrostis Lehmanniana) Invasion In A Semiarid Watershed
Moran, M. S., Scott, R. L., Hamerlynck, E. P., Green, K. N., Emmerich, W. E., Holifield Collins, C. D.

Across the western United States, warm-season grasslands are being invaded by the exotic perennial grass, Eragrostis lehmanniana (Lehmann lovegrass). The objective of this study was to quantify the change in surface water balance, particularly the evaporation from bare soil, associated with E. lehmanniana invasion. …

Seasonal Hydrology Explains Interannual And Seasonal Variation In Carbon And Water Exchange In A Semiarid Mature Ponderosa Pine Forest In Central Oregon
Thomas, C. K., Law, B. E., Irvine, J., Martin, J. G., Pettijohn, J. C., Davis, K. J.

We analyzed 7 years (2002–2008) of micrometeorological and concurrent biological observations of carbon and water fluxes at a mature ponderosa pine forest in central Oregon in a semiarid climate. We sought to evaluate the extent that gross primary productivity, net ecosystem exchange, ecosystem respiration, net primary productivity, …

Comparison Of Carbon Dynamics And Water Use Efficiency Following Fire And Harvesting In Canadian Boreal Forests
Mkhabela, M., Amiro, B., Barr, A., Black, T., Hawthorne, I., Kidston, J., McCaughey, J., Orchansky, A., Nesic, Z., Sass, A., Shashkov, A., Zha, T.

Fire and harvesting are major forest renewal processes in the Canadian boreal forest. The eddy covariance method was used to compare ecosystem fluxes of carbon dioxide between harvested and burned boreal forest sites in Saskatchewan, Canada. The harvest chronosequence had …

Nocturnal Evapotranspiration In Eddy-Covariance Records From Three Co-Located Ecosystems In The Southeastern U.S.: Implications For Annual Fluxes
Novick, K., Oren, R., Stoy, P., Siqueira, M., Katul, G.

Nocturnal evapotranspiration (ETN) is often assumed to be negligible in terrestrial ecosystems, reflecting the common assumption that plant stomata close at night to prevent water loss from transpiration. However, recent evidence across a wide …

Impact Of Reduced Tillage And Cover Cropping On The Greenhouse Gas Budget Of A Maize/Soybean Rotation Ecosystem
Bavin, T., Griffis, T., Baker, J., Venterea, R.

Agricultural ecosystems have been viewed with the potential to sequester atmospheric carbon dioxide (CO2) by increasing soil organic carbon (SOC) through reduced tillage and cover cropping practices. There remains considerable uncertainty, however, regarding the …
