Short-term response of Dicamptodon tenebrosus larvae to timber management in southwestern Oregon

Creator:: Leuthold, Niels, Adams, Michael J., and Hayes, John P.
Abstract:: In the Pacific Northwest, previous studies have found a negative effect of timber management on the abundance of stream amphibians, but results have been variable and region specific. These studies have generally used survey methods that did not account for differences in capture probability and focused on stands that were...

Relating Forest Attributes with Area- and Tree-Based Light Detection and Ranging Metrics for Western Oregon

Creator:: Goerndt, Michael E., Monleon, Vicente J., and Temesgen, Hailemariam
Abstract:: Three sets of linear models were developed to predict several forest attributes, using stand-level and single-tree remote sensing (STRS) light detection and ranging (LiDAR) metrics as predictor variables. The first used only area-level metrics (ALM) associated with first-return height distribution, percentage of cover, and canopy transparency. The second alternative included...

A comparison of small-area estimation techniques to estimate selected stand attributes using LiDAR-derived auxiliary variables

Creator:: Goerndt, Michael E., Monleon, Vicente J., and Temesgen, Hailemariam
Abstract:: One of the challenges often faced in forestry is the estimation of forest attributes for smaller areas of interest within a larger population. Small-area estimation (SAE) is a set of techniques well suited to estimation of forest attributes for small areas in which the existing sample size is small and...

Effects of glycol on leachability and efficacy of boron wood preservatives

Creator:: Gezer, Engin Derya, Michael, Judd H., and Morrell, Jeffrey J.
Abstract:: Although boron has many advantages as a wood preservative, this chemical performs poorly in leaching exposures. In this study, we investigated the potential for decreasing the leachability of boron preservatives with polyethylene glycol (PEG). Southern pine (Pinus spp.) test samples impregnated with combinations of sodium borate or boric acid and...

Effects of ungulate herbivory on aspen, cottonwood, and willow development under forest fuels treatment regimes

Creator:: Endress, Bryan A., Wisdom, Michael J., Vavra, Martin, Parks, Catherine G., Dick, Brian L., Naylor, Bridgett J., and Boyd, Jennifer M.
Abstract:: Herbivory by domestic and wild ungulates can dramatically affect vegetation structure, composition and dynamics in nearly every terrestrial ecosystem of the world. These effects are of particular concern in forests of western North America, where intensive herbivory by native and domestic ungulates has the potential to substantially reduce or eliminate...

Prediction of understory vegetation cover with airborne lidar in an interior ponderosa pine forest

Creator:: Wing, Brian M., Ritchie, Martin W., Boston, Kevin, Cohen, Warren B., Gitelman, Alix, and Olsen, Michael J.
Abstract:: Forest understory communities are important components in forest ecosystems providing wildlife habitat and influencing nutrient cycling, fuel loadings, fire behavior and tree species composition over time. One of the most widely utilized understory component metrics is understory vegetation cover, often used as a measure of vegetation abundance. To date, understory...

Effect of high temperature drying on permeability and treatment of western hemlock lumber

Creator:: Rhatigan, Ronald G., Milota, Michael R., Morrell, Jeffrey J., 1955-, and Lavery, Mark R.
Abstract:: The effect of drying conditions on gas permeability and preservative treatability was assessed on western hemlock lumber. Although there were no differences in gas permeability between lumber dried at conventional and high temperatures, there were differences in preservative penetration. High-temperature drying was associated with improved penetration of ammoniacal copper zinc...

Automated reconstruction of tree and canopy structure for modeling the internal canopy radiation regime

Creator:: van Leeuwen, Martin, Coops, Nicholas C., Hilker, Thomas, Wulder, Michael A., Newnham, Glenn J., and Culvenor, Darius S.
Abstract:: Understanding canopy radiation regimes is critical to successfully modeling vegetation growth and function. For instance, the vertical distribution of photosynthetically active radiation (PAR) affects vegetation growth, informative upon carbon and energy cycling. Availing upon advances in information capture and computing power, geometrically explicit modeling of forest structure becomes increasingly possible....

Prediction of Wood Fiber Attributes from LiDAR-Derived Forest Canopy Indicators

Creator:: Hilker, Thomas, Frazer, Gordon W., Coops, Nicholas C., Wulder, Michael A., Newnham, Glenn J., Stewart, James D., van Leeuwen, Martin, and Culvenor, Darius S.
Abstract:: We investigated the potential use of airborne light detection and ranging (LiDAR) data to predict key wood fiber properties from extrinsic indicators in lodgepole pine leading forest stands located in the foothills of central Alberta, Canada. Six wood fiber attributes (wood density, cell perimeter, cell coarseness, mature fiber length, microfibril...

Genome resequencing reveals multiscale geographic structure and extensive linkage disequilibrium in the forest tree Populus trichocarpa

Creator:: Slavov, Gancho T., DiFazio, Stephen P., Martin, Joel, Schackwitz, Wendy, Muchero, Wellington, Rodgers-Melnick, Eli, Lipphardt, Mindie F., Pennacchio, Christa P., Hellsten, Uffe, Pennacchio, Len A., Gunter, Lee E., Ranjan, Priya, Vining, Kelly, Pomraning, Kyle R., Wilhelm, Larry J., Pellegrini, Matteo, Mockler, Todd C., Freitag, Michael, Geraldes, Armando, El-Kassaby, Yousry A., Mansfield, Shawn D., Cronk, Quentin C. B., Douglas, Carl J., Strauss, Steven H., Rokhsar, Dan, and Tuskan, Gerald A.
Abstract:: •Plant population genomics informs evolutionary biology, breeding, conservation and bioenergy feedstock development. For example, the detection of reliable phenotype–genotype associations and molecular signatures of selection requires a detailed knowledge about genome-wide patterns of allele frequency variation, linkage disequilibrium and recombination. •We resequenced 16 genomes of the model tree Populus trichocarpa...
