Effects of stand density on the growth of young Douglas-fir trees

Creator:: Woodruff, David R., Bond, Barbara J., Ritchie, Gary A., and Scott, William
Abstract:: The objectives of this study were (i) to provide further evidence of a positive correlation of stand density with early growth of coastal Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii); (ii) to determine when after planting the positive growth response occurs and how long it lasts; and (iii) to use...

Hydraulic safety margins and embolism reversal in stems and leaves: Why are conifers and angiosperms so different?

Creator:: Johnson, Daniel M., McCulloh, Katherine A., Woodruff, David R., and Meinzer, Frederick C.
Abstract:: Angiosperm and coniferous tree species utilize a continuum of hydraulic strategies. Hydraulic safety margins (defined as differences between naturally occurring xylem pressures and pressures that would cause hydraulic dysfunction, or differences between pressures resulting in loss of hydraulic function in adjacent organs (e.g., stems vs. leaves) tend to be much...

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...

Comparative hydraulic architecture of tropical tree species representing a range of successional stages and wood density

Creator:: McCulloh, Katherine A., Meinzer, Frederick C., Sperry, John S., Lachenbruch, Barbara, Voelker, Steven L., Woodruff, David R., and Domec, Jean-Christophe
Abstract:: Plant hydraulic architecture (PHA) has been linked to water transport sufficiency, photosynthetic rates, growth form and attendant carbon allocation. Despite its influence on traits central to conferring an overall competitive advantage in a given environment, few studies have examined whether key aspects of PHA are indicative of successional stage, especially...

Dynamics of water transport and storage in conifers studied with deuterium and heat tracing techniques

Creator:: Meinzer, Frederick C., Brooks, J. R., Domec, Jean-Christophe, Gartner, Barbara L., Warren, J. M., Woodruff, D. R., Bible, K., and Shaw, D. C.
Abstract:: The volume and complexity of their vascular systems make the dynamics of long‐distance water transport in large trees difficult to study. We used heat and deuterated water (D₂O) as tracers to characterize whole‐tree water transport and storage properties in individual trees belonging to the coniferous species Pseudotsuga menziesii (Mirb.) Franco...

Conservation plans for the northern spotted owl and other forest management proposals in Oregon : the economics of changing timber availability

Creator:: Greber, Brian J., Johnson, K. Norman, and Lettman, Gary
Abstract:: The goal of this study is to analyze how the ISC Conservation Strategy may influence Oregon's timber availability and economy in the context of overall changes in public land management. Two themes are important: first, how the state's future will differ from today and second, how the state's future will...

Clonal expansion and seedling recruitment of Oregon grape (Berberis nervosa) in Douglas-fir (Pseudotsuga menziesii) forests: comparisons with salal (Gaultheria shallon)

Creator:: Huffman, David W. (William), 1962- and Tappeiner, John C.
Abstract:: Seedling regeneration and morphology of Oregon grape (Berberis nervosa Pursh) and salal (Gaultheria shallon Pursh) were studied in thinned and unthinned Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stands in the central Coast Range, Oregon. Above- and below-ground growth of both species were significantly and negatively correlated with stand density. Oregon grape...
