The American robin, Turdus migratorius, is one of the best known
birds in North America. Robins are the largest member of the thrush family. Thrushes have large eyes, long legs, and strong bodies. Robins are known for their habit of feeding on earthworms in lawns and for the song they...
Nonlinear optical processes can be described as multiphoton scattering events in terms of high order perturbation theory. The standard procedure for quantitative calculation of high order terms is to impose a steady state condition on the perturbative radiation fields. In the present work, this condition will be lifted, and explicit...
Convergent evolution is common throughout the tree of life, but the molecular mechanisms
causing similar phenotypes to appear repeatedly are obscure. Yeasts have arisen in multiple
fungal clades, but the genetic causes and consequences of their evolutionary origins are
unknown. Here we show that the potential to develop yeast forms...

Mixia osmundae (Basidiomycota, Pucciniomycotina) represents a monotypic class containing
an unusual fern pathogen with incompletely understood biology. We sequenced and analyzed
the genome of M. osmundae, focusing on genes that may provide some insight into its
mode of pathogenicity and reproductive biology.

This presentation provides a detailed overview of the ways in which the Oral History Program at the Oregon State University Library Special Collections and Archives Research Center has used the Oral History Metadata Synchronizer (OHMS), Omeka, an open source plug-in, and custom .css and .php scripting to make contextualized oral...
As decomposers, fungi are key players in recycling plant material in global carbon cycles. We hypothesized that genomes of early diverging fungi may have inherited pectinases from an ancestral species that had been able to extract nutrients from pectin-containing land plants and their algal allies (Streptophytes). We aimed to infer,...

This paper explores some theoretical and practical issues in developing policy for the management of shared fisheries for maximum value. Maximisation of value from the use of resources is a key component of sustainability, and transferable rights in commercial fisheries management have contributed significantly toward this goal. Maximising value becomes...
Custom, and the United Nations Convention on the Law of the Sea of 1982 (UNCLOS), provide the right of all states to exploit stocks of tuna on the high seas, where roughly half of world tuna catches are taken. The UNCLOS also provides that states have the obligation to cooperate...
The use of in situ measurements is essential in the validation and evaluation of the algorithms that provide coastal water quality data products from ocean colour satellite remote sensing. Over the past decade, various types of ocean colour algorithms have been developed to deal with the optical complexity of coastal...

The genomes of five Cochliobolus heterostrophus strains, two Cochliobolus sativus strains, three additional Cochliobolus species (Cochliobolus victoriae, Cochliobolus carbonum, Cochliobolus miyabeanus), and closely related Setosphaeria turcica were sequenced at the Joint Genome Institute (JGI). The datasets were used to identify SNPs between strains and species, unique genomic regions, core secondary...
In partially migratory species, such as Oncorhynchus mykiss, the emergence of life history phenotypes is often attributed
to fitness trade-offs associated with growth and survival. Fitness trade-offs can be linked to reproductive tactics that vary between
the sexes, as well as the influence of environmental conditions. We found that O....
A contingent valuation methodology was applied to old-growth forests and critical habitat units for the Northern Spotted Owl in Oregon to esimate the economic value to the public in knowing that rare and unique ecosystems will be protected from fire for current and future generations. Generalizing to the whole state,...
Apprentice programs offer a method to encourage responsible individual behavior by laying the foundation for successful collective property rights. Apprenticeship has three purposes: to restrict the rate of entry, to affect the quality of the participant, and to create the conditions for collective action for sustainability. Apprenticeship could be an...
The objective of this lab is to gain experience collecting imagery with an unmanned aircraft system (UAS) and processing it in structure from motion (SfM) photogrammetry software to obtain georeferenced data products, including an orthomosaic in GeoTiff format and a point cloud in ASPRS’s LAS format.
Surface transient storage (STS) and hyporheic transient storage (HTS) have
functional significance in stream ecology and hydrology. Both provide refugia for aquatic
communities and their longer mean residence times (compared to the main flow) increase
the potential for biogeochemical reactions that can improve water quality. As STS and

These course materials provide students with a theoretical and practical background in operational use of UAS for surveying and mapping. Instructors can use these modules for a standalone course or integrate select modules into their existing curricula, as desired. Specifically, these materials cover the following learning outcomes to enable students...
An experiment evaluating three levels of vegetation competition control (no control, 1.5 m2 of vegetation control, and 3.3 m2 of vegetation control), each with two fertilization treatments (fertilization at the time of planting with complete slow-release fertilizer (Woodace® IBDU), or no fertilization), was installed at five sites. Two of these...

marking the predicted base of the gas-hydrate stability...
Reproductive tactics and migratory strategies in Pacific and Atlantic salmonines are inextricably linked through the effects of migration (or lack thereof) on age and size at maturity. In this review, we focus on the ecological and evolutionary patterns of freshwater maturation in salmonines, a key process resulting in the diversification...
An error in the calculation of the baroclinic pressure gradient term in the Princeton Ocean Model (POM) was identified while modeling the M₂ tidal current near its critical latitude in the southern Weddell Sea. The error arises from the present calculation of density, which involves the subtraction of a background...
Measurement of a quantum system - the process by which an observer gathers information about it - provides a link between the quantum and classical worlds. The nature of this process is the central issue for attempts to reconcile quantum and classical descriptions of physical processes. Here, we show that...
This report was written as a resource for water quality managers, watershed councils, municipalities and citizens to help understand the status of watershed conditions in the Willamette Basin. Our interpretations are based on chemical, physical and biological indicators at three different spatial scales: the basin scale, the subbasin scale and...
