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, …

Woody Plants Modulate The Temporal Dynamics Of Soil Moisture In A Semi-Arid Mesquite Savanna
Potts, D. L., Scott, R. L., Bayram, S., Carbonara, J.

Climate variability and human activities interact to increase the abundance of woody plants in arid and semi-arid ecosystems worldwide. How woody plants interact with rainfall …

Biological And Physical Influences On The Carbon Isotope Content Of Co2 In A Subalpine Forest Snowpack, Niwot Ridge, Colorado
Bowling, D. R., Massman, W. J., Schaeffer, S. M., Burns, S. P., Monson, R. K., Williams, M. W.

Considerable research has recently been devoted to understanding biogeochemical processes under winter snow cover, leading to enhanced appreciation of the importance of many winter ecological processes. In this study, a comprehensive investigation of the stable carbon isotope composition (δ13C) of CO2 within a high-elevation subalpine …

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 …

Soil, Plant, And Transport Influences On Methane In A Subalpine Forest Under High Ultraviolet Irradiance
Bowling, D. R., Miller, J. B., Rhodes, M. E., Burns, S. P., Monson, R. K., Baer, D.

Recent studies have demonstrated direct methane emission from plant foliage under aerobic conditions, particularly under high ultraviolet (UV) irradiance. We examined the potential importance of this phenomenon in a high-elevation conifer forest using micrometeorological techniques. Vertical profiles of methane and carbon dioxide …

The Ecohydrologic Significance Of Hydraulic Redistribution In A Semiarid Savanna
Scott, R. L., Cable, W. L., Hultine, K. R.

Recent studies have illuminated the process of hydraulic redistribution, defined as the translocation of soil moisture via plant root systems, but the long-term ecohydrologic significance of this process is poorly understood. We investigated hydraulic redistribution (HR) by Prosopis velutina Woot. (velvet mesquite) in an …

Influence Of Vegetation And Seasonal Forcing On Carbon Dioxide Fluxes Across The Upper Midwest, Usa: Implications For Regional Scaling
Desai, A. R., Noormets, A., Bolstad, P. V., Chen, J., Cook, B. D., Davis, K. J., Euskirchen, E. S., Gough, C., Martin, J. G., Ricciuto, D. M., Schmid, H. P., Tang, J., Wang, W.

Carbon dioxide fluxes were examined over the growing seasons of 2002 and 2003 from 14 different sites in Upper Midwest (USA) to assess spatial variability of ecosystem–atmosphere CO2 exchange. These sites were exposed to similar temperature/precipitation regimes and spanned a range of vegetation types typical of the …

Environmental And Biological Controls On Water And Energy Exchange In Florida Scrub Oak And Pine Flatwoods Ecosystems
Bracho, R., Powell, T. L., Dore, S., Li, J., Hinkle, C. R., Drake, B. G.

Scrub oak and pine flatwoods are two contrasting ecosystems common to the humid subtropical climate of Florida. Scrub oak forests are short in stature (<2 m) and occur on well-drained sandy soils, and pine flatwoods are much taller and occur in areas with poorly drained soils. Eddy covariance measurements were made from January …

Temporal Changes In C And N Stocks Of Restored Prairie: Implications For C Sequestration Strategies
Matamala, R., Jastrow, J. D., Miller, R. M., Garten, C. T.

The recovery of ecosystem C and N dynamics after disturbance can be a slow process. Chronosequence approaches offer unique opportunities to use space-for-time substitution to quantify the recovery of ecosystem …
