Land-use in the Willamette Valley from 2004-2017

Creator:: Strimbu, Bogdan M., Mueller-Warrant, George, and Trippe, Kristin
Abstract:: The Willamette Valley, bounded on the west by the Coast Range and on the east by the Cascade Mountains, is the largest river valley completely confined to Oregon. The fertile valley soils combined with a temperate, marine climate create ideal agronomic conditions for seed production. Historically, seed cropping systems in...

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...

Assessing the Carbon Consequences of Western Juniper (Juniperus occidentalis) Encroachment Across Oregon, USA

Creator:: Campbell, John L., Kennedy, Robert E., Cohen, Warren B., and Miller, Richard F.
Abstract:: Our ability to assess the continental impacts of woody encroachment remains compromised by the paucity of studies quantifying regional encroachment rates. This knowledge gap is especially apparent when it comes to quantifying the impact of woody encroachment on large-scale carbon dynamics. In this study, we use a combination of aerial...

A comparison of selected parametric and imputation methods for estimating snag density and snag quality attributes

Creator:: Eskelson, B. N. I., Temesgen, Hailemariam, and Hagar, J. C.
Abstract:: Snags (standing dead trees) are an essential structural component of forests. Because wildlife use of snags depends on size and decay stage, snag density estimation without any information about snag quality attributes is of little value for wildlife management decision makers. Little work has been done to develop models that...

Burning the legacy? Influence of wildfire reburn on dead wood dynamics in a temperate conifer forest

Creator:: Donato, Daniel C., Fontaine, Joseph B., and Campbell, John L.
Abstract:: Dynamics of dead wood, a key component of forest structure, are not well described for mixed-severity fire regimes with widely varying fire intervals. A prominent form of such variation is when two stand-replacing fires occur in rapid succession, commonly termed an early-seral “reburn.” These events are thought to strongly influence...

Bees of the Pacific Northwest : key to genera (Hymenoptera : Anthophila)

Creator:: Best, Lincoln R., Dunlap, Joshua B., Jackson, August S., and Rivers, James W.
Abstract:: This key to the bee genera of the Pacific Northwest provides dichotomous couplets which aid the user in identifying 60 genera of bees which occur or may occur in the region. The key architecture is based strongly on the key to the genera of North and Central America published in...

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...

Bees of the Pacific Northwest : key to bumble bee species for females (Hymenoptera : Apidae : Bombus)

Creator:: Best, Lincoln R., Dunlap, Joshua B., Jackson, August S., Rivers, James W., and Williams, Paul H.
Abstract:: This species key to female bumble bees of the Pacific Northwest provides dichotomous couplets which aid the user in identifying 27 species which occur or have occurred historically, and may still be present in the region. The key architecture is based strongly on the key to species for females found...

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...
