Fifty years of change in a Pacific Northwest winter forest bird community

Creator:: Clements, Nolan
Abstract:: North American bird populations have declined throughout the past half century. The majority of studies quantifying these declines have focused on spring and summer breeding birds; not the season of scarcity, winter. We re-surveyed 7 large study plots in Douglas fir forests initially surveyed in winter during the late 1960s...

Songbird feathers as indicators of mercury exposure : Patterns across feather tracts and correlations to other tissues

Creator:: Low, Katherine E.
Abstract:: Monitoring mercury (Hg) exposure in avian populations is critical to understanding the effects of this neurotoxin. Avian Hg exposure is commonly evaluated by measuring Hg concentrations in internal tissues, blood, and feathers. Feathers are a popular sampling matrix due to ease of sampling and limited stress to birds. However, it...

Avian Community Assembly Following Volcanic Disturbance at Volcán Arenal, Costa Rica and Mount St. Helens, USA

Creator:: Fairchild, Karl C.
Abstract:: Volcanism is an agent of major disturbance in many parts of the world. While the effects of volcanic disturbance are fairly well-known among some groups of species, few studies have been performed in bird communities. Likewise, few studies have attempted to compare how communities in temperate and tropical biomes respond...

Ecology and distribution of red crossbill call types in western Oregon

Creator:: Centanni, Caleb
Abstract:: Red Crossbills (Fringillidae: Loxia curvirostra), irruptive finches which feed on conifer seeds, have long presented an evolutionary conundrum. Variable morphology and vocalizations in the species can be classified into several flight call types, which may be discrete lineages. The key conifer hypothesis suggests that each type diverged by specializing on...

Thin-Film Dielectric Structure of Spin-Coated ZrO2 from Aqueous Inorganic Solution

Creator:: Moreno Luna, Hidekel A.
Abstract:: An inorganic aqueous precursor for the deposition of ZrO2 thin films via spincoating was developed. Hydrolysis and condensation chemistries of ZrOCl₂·8H₂O were used as the principal reactions to guide the synthesis. Refractive index, n, for a film annealed at 300 °C at 550 nm was measured to be n=1.97 by...

Comparing Native Oral History and Scientific Research to Produce Historical Evidence of Native Occupation During and After the Missoula Floods

Creator:: Woodside, Gail J.
Abstract:: The Missoula Floods occurred approximately fifteen thousand to thirteen thousand years ago during the last ice age. The floods occurred when waters held back by a finger of the Purcell Ice Lobe gave way allowing water which covered present day Missoula, Montana to inundate areas of Idaho, Washington, and Oregon....

Adaptation to long-term osmotic stress in a domesticated Saccharomyces cerevisiae strain

Creator:: Holman, Douglas S.
Abstract:: Osmotic stress is a common challenge faced by organisms in environments with variable salinity or aridity. Understanding the evolutionary mechanisms underlying adaptation to osmotic stress may have wide applications, including management of populations experiencing climate change, or engineering industrial organisms involved in processes such as fermentation. While Saccharomyces cerevisiae is...

Prevalence of Canine Brucellosis in the United States

Creator:: Douglas, Lisa
Abstract:: Brucella canis is a zoonotic proteobacterium causing brucellosis in dogs and other wild canidae. It is primarily spread to the fetus through the placenta, to other dogs through fetal fluids and vaginal discharge after abortion, and to mating partners through vaginal and seminal fluids. Transmission to other dogs can also...

A genomic and proteomic characterization of the first cultured oligotrophic marine Gammaproteobacterium from the SAR92 clade

Creator:: Mellbye, Brett L.
Abstract:: High-throughput culturing (HTC) consisting of extinction culturing in autoclaved seawater has led to the isolation and characterization of many novel strains of oligotrophic marine bacteria. Strain HTCC 2207 was isolated from the Oregon coast by the HTC method. Phylogenetic analysis based on 16S rRNA gene sequence showed that this strain...

Interactive visualization of Douglas fir forest growth using 3-PG

Creator:: Thompson, Allison
Abstract:: Forests are important to Oregon for their beauty as well as economic value, and Douglas fir trees are among the most common and important in the state. Managing and monitoring Oregon’s forests is imperative to ensure they can remain healthy and productive. One tool that helps forest scientists to understand...
