Fungi colonizing redwood in cooling towers: Identities and effects on wood properties

Creator:: Morrell, Jeffrey J. and Smith, Susan M.
Abstract:: Heartwood from coastal redwood [Sequoia sempervirens (D. Don.) Endl.] is very durable and is often used untreated in harsh environments, such as cooling towers of power or chemical processing plants. Wood in this environment is often attacked by soft rot fungi. Some wood users attempt to bolster protection by including...

Supercritical fluid (SCF) treatment: Its effect on bending strength and stiffness of ponderosa pine sapwood

Creator:: Smith, Susan M., Demessie, E. Sahle, Morrell, Jeffrey J., Levien, Keith L., and Ng, Harry
Abstract:: Adverse effects on mechanical properties from using a supercritical fluid (SCF) to increase preservative penetration of refractory woods were evaluated by treating small ponderosa pine sapwood specimens with supercritical carbon dioxide at 64 combinations of temperatures (35 to 80 C), pressure (1,000 to 4,000 psig), and time (0.5 to 2...

Arbutus menziesii (Ericaceae) facilitates regeneration dynamics in mixed evergreen forests by promoting mycorrhizal fungal diversity and host connectivity

Creator:: Kennedy, Peter G., Smith, Dylan P., Horton, Tom R., and Molina, Randy J.
Abstract:: • Premise of study: In the mixed evergreen forests in the western United States, Arbutus menziesii is able to quickly resprout following disturbance and, as such, act as a nurse tree during forest regeneration. The mechanism for this nurse tree effect has frequently been ascribed to mycorrhizal fungi, but no...

Evidence for Mate Guarding Behavior in the Taylor's Checkerspot Butterfly

Creator:: Bennett, Victoria J., Smith, Winston P., and Betts, Matthew G.
Abstract:: Discerning the intricacies of mating systems in butterflies can be difficult, particularly when multiple mating strategies are employed and are cryptic and not exclusive. We observed the behavior and habitat use of 113 male Taylor’s checkerspot butterflies (Euphydryas editha taylori). We confirmed that two distinct mating strategies were exhibited; patrolling...

Shared compatibility of ectomycorrhizae on Pseudotsuga menziesii and Betula papyrifera seedlings grown in mixture in soils from southern British Columbia

Creator:: Simard, Suzanne W., Molina, Randy, Smith, Jane E., Perry, David A., and Jones, Melanie D.
Abstract:: Seedlings of Pseudotsuga menziesii (Mirb.) Franco and Betula papyrifera Marsh. were grown in the greenhouse in monoculture and dual culture in soils collected from a young mixed species plantation in the southern interior of British Columbia. The objectives of the study were (i) to evaluate the ability of P. menziesii...

Patterns of xylem variation within a tree and their hydraulic and mechanical consequences

Creator:: Gartner, Barbara L.
Abstract:: Xylem is nonuniform in its structure and function throughout the plant stem. Xylem structure varies from pith to bark, from root to apical meristem, from stem to branch, at nodes vs internodes, and at junctions of branches, stems or roots compared to the internodal regions nearby. At smaller scales, anatomy...

A Dual-Objective-Based Tornado Design Philosophy

Creator:: van de Lindt, John W., Pei, Shiling, Dao, Thang, Graettinger, Andrew, Prevatt, David O., Gupta, Rakesh, and Coulbourne, William
Abstract:: Tornadoes represent a unique natural hazard because of the very low probability of occurrence, short warning times (on the order of only a few minutes), and the intense and destructive forces imposed on engineered and non-engineered buildings. The very low-probability very high-consequence nature of a tornado strike makes designing for...
