In 2012 Oregon State University hosted the Oregon Tribal Archives Institute (OTAI), a week long archival
education training opportunity specifically designed for Oregon’s nine federally recognized tribes. This
article describes the OTAI project development, organization, and implementation. The authors offer
various lessons learned that can be applied by others who...
Stable oxygen and carbon isotope δ[superscript 18]O and δ[superscript 13]C analyses of otoliths are becoming increasingly common in fisheries science and management. However, little is known about the statistical properties of isotopic data and few attempts have been made to explore appropriate statistical methods that could be used for otolith...
Engineering is largely concerned with models and modelling. Models provide a context in which decisions are made. Here the modelling process is considered in a general sense and then the relationship with engineering models is developed. For understanding, a first step is to differentiate and categorize. Thus ten types of...
The responsibilities which civil engineers, and particularly the engineer of record, accept are considered. The interaction with other decision makers such as the owner, stakeholders, the law and contractors results in complexity that can be partially resolved by the introduction of protocols in the form of regulations and codes of...
Piscivory by birds can be significant, particularly on fish in small streams and during seasonal low flow when available cover from predators can be limited. Yet, how varying amounts of cover may change the extent of predation mortality from avian predators on fish is not clear. We evaluated size-selective survival...
Results of 28 field trials conducted over a 12-year period investigating management of hop powdery mildew caused by Podosphaera macularis were quantitatively summarized by meta-analysis to compare product efficacy and use patterns by mode of action as defined by Fungicide Resistance Action Committee (FRAC) groups. Availability of original observations enabled...
We used simulated magnetic displacements to test orientation preferences of juvenile steelhead trout (Oncorhynchus mykiss) exposed to magnetic fields existing at the northernmost and southernmost boundaries of their oceanic range. Fish reared in natural magnetic conditions distinguished between these two fields by orienting in opposite directions, with headings that would...
The federally threatened northern spotted owl (Strix occidentalis caurina) is the focus of intensive
conservation efforts that have led to much forested land being reserved as habitat for the owl and associated wildlife
species throughout the Pacific Northwest of the United States. Recently, however, a relatively new threat to spotted...
Morphologically divergent ecotypes arise in fish populations on postglacial time scales, and resource polymorphisms
are often invoked to explain their origin. However, genetic recombination can constrain the ability of divergent selection to produce
reproductive isolation in sympatry. Recombination breaks up favorable combinations of traits (”adaptive suites”) if individual
traits are...
