This book is an environmental primer for the people of the Willamette Valley. It sets forth basic principles showing how men's actions cause future consequences in the environment.
Forty-nine genera and ninty-eight species of Lichenized fungi are reported from the H. J. Andrews Experimental Forest (Oregon). Substrates, growth form, and type of phycobiont are indicated for each taxon.
This research focused on the use of classical and modern two-dimensional spectral estimation techniques for enhancing inverse synthetic aperture radar (ISAR) imagery. 2-D Classical spectral estimation methods and 2-D modern parametric and non-parametric spectral estimation methods are applied to simulated and real data sets in order to achieve both range...
Polycyclic aromatic hydrocarbons (PAHs) are significant pollutants in aquatic environments. Many are carcinogenic and lead to DNA fragmentation and adduct formation in marine and freshwater organisms. Previous research demonstrates that rainbow trout (Oncorhynchus mykiss) compensate to long-term PAH dietary exposures and reduce the DNA damage.
The aim of this study...
The earth is undergoing a “biodiversity crisis” characterized by loss of populations, species, genetic diversity, and ecosystem services. Part of this crisis consists of population declines, extinctions, and increased incidence of deformities in amphibians. It is unknown whether deformities contribute to these declines. Many cases of population declines in amphibians...
Wheat is a globally traded staple crop. Wheat is important in human diets because of its agronomic adaptability, physical characteristics, functionality for the production of leavened products and nutritional value. Two significant characteristics make wheat an important staple food-crop. First, the proteins present in wheat endosperm have attributes that enable...
The absence of federal climate legislation in the United States has led to a growth of sub-federal and non-governmental programs to combat greenhouse gas emissions. One such program, the American College and University Presidents’ Climate Commitment (ACUPCC) seeks to mitigate greenhouse emissions from higher education through the voluntary commitment of...
Emerging infectious diseases are increasing globally and are a threat to human, wildlife, and ecosystem health. The emerging fungal pathogen, Batrachochytrium dendrobatidis (Bd), or amphibian chytrid fungus, is associated with worldwide amphibian population declines and extinctions. Bd has been found on every continent where amphibians exist and has been documented...
Pactamycin, a complex aminocyclitol compound produced by Streptomyces pactum, has significant antibiotic, antitumor, and antiplasmodial activity. However, this natural product has not been developed for clinical use due to its high cytotoxicity. Modulation of its biological properties by chemical synthesis has been difficult due to its complex chemical structure. Therefore,...

Chitosan based hemorrhage control dressings provide effective external hemorrhage control while having few side effects. Known residual contaminants present in chitosan formulations include endotoxins and proteins known to stimulate gene expression in the liver. This study investigated gene expression in the liver using rat bio-compatibility models to gain knowledge regarding...

Controversy regarding moral development research has given rise to a proliferation of theories competing for acceptance. For all these researchers, the work of Lawrence Kohlberg is the pivot point for comparisons, contrasts, and discussions. Still, no theories to date adequately describe and document a theoretically complete conception of moral judgment...
Normal faults characterizing extensional provinces may terminate along-strike at regions of zero extension, at zones of transform faults, or at triple junctions. Termination of the Basin and Range extensional province in southeastern Oregon is thought to occur by right-lateral transform motion distributed across the Brothers Fault zone (BFZ) in central...
The atmospheric transport and deposition of semi-volatile organic compounds (SOCs), including current and historic use pesticides, polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs), to mountain ecosystems may result in the exposure of tadpoles to these SOCs. This exposure has been implicated in amphibian population declines in California. Tadpoles encounter...
Characteristics of minke whale (Balaenoptera acutorostrata) habitat at the head of the Laurentian Channel in the St. Lawrence Estuary, Canada were identified by quantifying environmental and temporal habitat variables and comparing them to the presence or absence of minke whales during the summer of 1996. Identification photographs of minke whales...
This research examines the response from the National Rifle Association (NRA) to the tragic shooting at Sandy Hook Elementary School on December 14, 2012. Specifically, the research seeks to conclude whether the NRA engaged in propaganda, and if so, what the ethical implications of such use are. Using literature from...
For adult learners to succeed in their educational endeavors, adult educators and event planners must meet their needs and goals (Storksdieck, Ellenbogen, & Heimlich, 2005). The learning environment affects how adults learn and what outcomes they achieve (e.g., Hamilton & Tee, 2010; Knowles, 1990; Lim, Morris, & Kupritz, 2007; Young,...
