Evidence for xylem embolism as a primary factor in dehydration-induced declines in leaf hydraulic conductance

Creator:

Johnson, Daniel M., McCulloh, Katherine A., Woodruff, David R., and Meinzer, Frederick C.

Abstract:

Hydraulic conductance of leaves (K[subscript leaf]) typically decreases with increasing water stress and recent studies have proposed different mechanisms responsible for decreasing K[subscript leaf]. We measured K[subscript leaf] concurrently with ultrasonic acoustic emissions (UAEs) in dehydrating leaves of several species to determine whether declining K[subscript leaf] was associated with xylem...

Reconciling estimates of the contemporary North American carbon balance among terrestrial biosphere models, atmospheric inversions, and a new approach for estimating net ecosystem exchange from inventory-based data

Creator:

Hayes, Daniel J., Turner, David P., Stinson, Graham, McGuire, A. David, Wei, Yaxing, West, Tristram O., Heath, Linda S., de Jong, Bernardus, McConkey, Brian G., Birdsey, Richard A., Kurz, Werner A., Jacobson, Andrew R., Huntzinger, Deborah N., Pan, Yude, Post, W. Mac, and Cook, Robert B.

Abstract:

We develop an approach for estimating net ecosystem exchange (NEE) using inventory-based information over North America (NA) for a recent 7-year period (ca. 2000–2006). The approach notably retains information on the spatial distribution of NEE, or the vertical exchange between land and atmosphere of all non-fossil fuel sources and sinks...
