When Vegetation Change Alters Ecosystem Water Availability
Scott, R. L., Huxman, T. E., Barron-Gafford, G. A., Darrel Jenerette, G., Young, J. M., Hamerlynck, E. P.

The combined effects of vegetation and climate change on biosphere–atmosphere water vapor (H2O) and carbon dioxide (CO2) exchanges are expected to vary depending, in part, on how biotic activity is controlled by and alters water availability. This is particularly important when a change in ecosystem composition alters the fractional …

Multiyear Riparian Evapotranspiration And Groundwater Use For A Semiarid Watershed
Scott, R., Cable, W., Huxman, T., Nagler, P., Hernandez, M., Goodrich, D.

Riparian evapotranspiration (ET) is a major component of the surface and subsurface water balance for many semiarid watersheds. Measurement or model-based estimates of ET are often made on a local scale, but spatially distributed estimates are needed to determine ET over catchments. In this paper, we document the ET that was quantified …

Intraseasonal Variation In Water And Carbon Dioxide Flux Components In A Semiarid Riparian Woodland
Yepez, E. A., Scott, R. L., Cable, W. L., Williams, D. G.

We investigated how the distribution of precipitation over a growing season influences the coupling
of carbon and water cycle components in a semiarid floodplain woodland dominated by the deep-rooted velvet mesquite (Prosopis velutina). Gross ecosystem production (GEP) and ecosystem respiration (Reco) were frequently uncoupled because …

Ecohydrological Impacts Of Woody-Plant Encroachment: Seasonal Patterns Of Water And Carbon Dioxide Exchange Within A Semiarid Riparian Environment
SCOTT, R. L., HUXMAN, T. E., WILLIAMS, D. G., GOODRICH, D. C.

Across many dryland regions, historically grass-dominated ecosystems have been encroached upon by woody-plant species. In this paper, we compare ecosystem water and carbon dioxide (CO2) fluxes over a grassland, a grassland–shrubland mosaic, and a fully developed woodland to evaluate potential consequences of woody-plant encroachment …

Interannual And Seasonal Variation In Fluxes Of Water And Carbon Dioxide From A Riparian Woodland Ecosystem
Scott, R. L., Edwards, E. A., Shuttleworth, W., Huxman, T. E., Watts, C., Goodrich, D. C.

Fluxes of water, energy and carbon dioxide (CO2) were measured using the eddy covariance technique over a mesquite (Prosopis velutina) woodland along the San Pedro River in southeastern Arizona for the entire growing seasons of 2001 and 2002, between the last freeze event of spring and the first of fall. Although the general pattern …
