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...

Tertiary geologic framework, neotectonics, and petroleum potential of the Oregon-Washington Continental Margin

Creator:

Snavely, P. D., Jr. and Geological Survey (U.S.)

Abstract:

The Tertiary geologic evolution of the Oregon and Washington continental margin was molded by episodic periods of convergence between the Pacific oceanic plates and the North American plate. This margin is the site of a deep basin that is floored by Paleocene to lower Eocene oceanic crust and contains more...
