Modeling Whole-Tree Carbon Assimilation Rate Using Observed Transpiration Rates And Needle Sugar Carbon Isotope Ratios
Hu, J., Moore, D. J., Riveros-Iregui, D. A., Burns, S. P., Monson, R. K.

• Understanding controls over plant–atmosphere CO 2 exchange is important for
quantifying carbon budgets across a range of spatial and temporal scales. In this
study, we used a simple approach to estimate whole-tree CO 2 assimilation rate
(A Tree ) in a subalpine forest ecosystem.
• We analysed the carbon isotope ratio …

Tree Species Effects On Ecosystem Water-Use Efficiency In A High-Elevation, Subalpine Forest
Monson, R. K., Prater, M. R., Hu, J., Burns, S. P., Sparks, J. P., Sparks, K. L., Scott-Denton, L. E.

Ecosystem water-use efficiency (eWUE; the ratio of net ecosystem productivity to evapotranspiration rate) is a complex landscape-scale parameter controlled by both physical and biological processes occurring in soil and plants. Leaf WUE (lWUE; the ratio of leaf CO2 assimilation rate to transpiration rate) is controlled at short time …

Longer Growing Seasons Lead To Less Carbon Sequestration By A Subalpine Forest
Hu, J., Moore, D. J., Burns, S. P., Monson, R. K.

As global temperatures increase, the potential for longer growing seasons to enhance the terrestrial carbon sink has been proposed as a mechanism to reduce the rate of further warming. At the Niwot Ridge AmeriFlux site, a subalpine forest in the Colorado Rocky Mountains, we used a 9‐year record (1999–2007) of continuous eddy …

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 …

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, …
