Creator:: Miller, D. B. and Morrell, Jeffrey J.
Abstract:: Vapam(r) (NaMDC) is the fumigant most commonly used to arrest and control decay of utility poles. While volatile fungitoxins are detectable only 1 to 2 years after treatment, poles treated with Vapam(r) remain free of decay fungi for 6 to 17 years. Vapam(r) decomposes to produce volatile fungicides as well...

Abstract:: The factors that determine sapwood width and volume in a tree are not known. This study asked whether sapwood width is related to a need for stem storage sites. Experiments were conducted on 12 34-year-old Douglas-fir [(Pseudotsuga menziesii (Mirb.) Franco] trees with a 6-7 fold range of leaf areas and...

Abstract:: The physical demands of rapid and economical running differ from the demands of fighting in ways that may prevent the simultaneous evolution of optimal performance in these two behaviors. Here, we test an hypothesis of functional trade-off in limb bones by measuring mechanical properties of limb bones in two breeds...

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...

Creator:: Vatovec, M., Miller, T. H., Gupta, R., and Lewis, S.
Abstract:: A previously developed, three-dimensional (3-D) finite-element (FE) joint model and several two-dimensional (2-D), beam-element based FE models with different joint-stiffness assumptions (pinned, rigid, and semi-rigid) were used to analyze the full-scale behavior of a metal-plate-connected (MPC) wood scissors truss. The truss displacement and force results were investigated for sensitivity with...

Creator:: Vatovec, M., Miller, T. H., and Gupta, R.
Abstract:: A commercially available, three-dimensional finite-element analysis software was used to model the load-displacement behavior of metal-plate-connected (MPC) joints in wooden trusses. Model features included consideration of material properties, teeth-to-grain-to-direction-of-force orientation, wood-to-wood interaction, and gaps between wood members. To simulate wood-to-plate interaction, the main feature of the model, each tooth of...

Abstract:: Fungal mitospores may function as dispersal units and/ or spermatia, and thus play a role in distribution and/or mating of species that produce them. Mitospore production in ectomycorrhizal (EcM) Pezizales is rarely reported, but here we document mitospore production by a high diversity of EcM Pezizales on three continents, in...

Abstract:: The inter-relationships among δ¹³C and δ¹⁸O in tree ring cellulose and ring width have the potential to illuminate long-term physiological and environmental information in forest stands that have not been monitored. We examine how within-stand competition and environmental gradients affect ring widths and the stable isotopes of cellulose. We utilize...

Creator:: Gupta, R., Gebremedhin, K. G., and Cook, J. R.
Abstract:: Metal-plate-connected wood trusses with semi-rigid joints were investigated by the matrix method of structural analysis. The element-stiffness matrix and fixed-end forces of an individual member with one or both ends semi-rigid were derived as modifications of the idealized cases. The case of unequal elastic connections at two ends of a...

Abstract:: ASTM standard sizes for bending tests (either 50 × 50 mm or 25 × 25 mm in cross-section) are not always suitable for research purposes that characterize smaller sections of wood. Moreover, the ASTM standards specify loading the sample on the longitudinal-tangential surface. If specimens are small enough, then the...
