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...

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...

Effects of release from suppression on wood functional characteristics in young Douglas-fir and western hemlock

Creator:: Renninger, Heidi J., Gartner, Barbara L., and Meinzer, Frederick C.
Abstract:: Little is known of wood properties in trees that were initially suppressed and subsequently released from suppression. The purpose of this study was to assess differences in growth ring width, specific conductivity (Ks), tracheid dimensions, moisture content, and wood density in suppressed Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) and western hemlock...

Potential for Using Essential Oils to Protect Viscoelastic Thermal Compression–Treated Hybrid Poplar

Creator:: Scouse, Adam, Kamke, Frederick A., and Morrell, Jeffrey J.
Abstract:: The potential for using pretreatment with cinnamon leaf oil or juniper foliage oil to improve the durability of viscoelastic thermal compression (VTC)–treated hybrid poplar was explored in a field termite test and a laboratory mold test. The addition of oils prior to VTC processing had variable effects on resistance to...

Development of Douglas-fir seedling root architecture in response to localized nutrient supply

Creator:: Jacobs, Douglass Frederick, Rose, Robin, and Haase, Diane L.
Abstract:: Three months following sowing, Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings were transplanted into pots with controlled-release fertilizer (CRF) applied at rates of 0, 8, 16, and 24 g/2200 cm3 soil as a single uniform layer beneath the root system. Seedlings were destructively harvested periodically, and roots were divided into vertical...

Influence of the thermo-hydro-mechanical treatments of wood on the performance against wood degrading fungi

Creator:: Lesar, Bostjan, Humar, Miha, Kamke, Frederick A., and Kutnar, Andreja
Abstract:: Hybrid poplar (Populus deltoides × Populus trichocarpa) and Douglas-fir (Pseudotsuga menziesii) wood specimens were densified with three variations of Thermo-Hydro-Mechanical (THM) treatment. The THM treatments differed in the steam environment, including transient steam (TS), saturated steam (SS), and saturated steam with 1 minute post-heat-treatment at 200°C (SS+PHT). The bending properties,...

Estimation and analysis of costs for developed recreation sites in U.S. Forest Service Region One

Creator:: Gibbs, Kenneth C., Reed, Frederick L., and Oregon State University. Forest Research Laboratory
Abstract:: An economic cost analysis of 258 Forest Service developed recreation sites in Region One examined eleven different site types, including campgrounds, picnic grounds, boating and swimming sites, interpretive sites, and information sites. Costs were estimated for planning, facilities, and operation and maintenance. Averaging costs by category showed that, in general,...
