Small mountainous watersheds are disproportionate sources of land-derived particulate organic matter (POM) to long-term sinks like lake bottoms and the ocean. As such, these ecosystems are an essential component of the global carbon cycle. The burial of POM in lacustrine and marine sediments contributes to the drawdown of atmospheric CO2...
Managing agricultural diversity ensures a range of public services, such as genetic resource diversity, food security for subsistence-based economies, and landscape resilience in the context of climate change, among others. These agrobiodiversity conservation services are positive externalities from agrobiodiversity conservation. Whereas their value is not captured in market transactions, management...
The present study employs a normalized restricted quadratic profit function approach to estimate lumber and plywood supply and Marshallian factor demand elasticities for four region-product combinations in Oregon for the period 1970-2010. The four log demand functions will be employed as the "demand side" of the log market model of...
Along the Pacific coast of North America, from Alaska to Mexico, harmful algal blooms (HABs) have caused losses to natural resources and coastal economies, and have resulted in human sicknesses and deaths for decades. Recent reports indicate a possible increase in their prevalence and impacts of these events on living...
Background: The identification of proteins by mass spectrometry is a standard method in biopharmaceutical quality control and biochemical research. Prior to identification by mass spectrometry, proteins are usually pre-separated by electrophoresis. However, current protein staining and de-staining protocols are tedious and time consuming, and therefore prolong the sample preparation time...

Until the 1930s, flows of the Colorado River maintained approximately 781,060 hectares of wetlands in its delta. These wetlands provided important feeding and nesting grounds for resident and migratory birds as well as spawning and protection habitat for many fish and other invertebrate species. However, the Delta's wetlands started to...
Small-scale fisheries often suffer from weak, formal governance, and in response they organize in various ways. These self-organizational arrangements rely on the capacity of informal institutions, such as norms and communication, in generating social cohesion among actors in the supply chain and therefore improve the likelihood of generating commonly devised...

In the most challenging nuclear power plant accidents, transient critical heat flux (CHF) is a primary phenomenon that drives peak cladding temperature and ultimately fuel failure. It is not yet determined whether the use of steady-state CHF methods can accurately predict transient CHF under the conditions of a blowdown due...
Current bridge design codes do not account for the effects of duration of mega-thrust subduction zone earthquakes. Furthermore, codes and even recent performance-based design methodologies only make use of the peak response quantities (forces, displacements, and ductility demands) and do not account for the increased number of inelastic cycles that...
Pollution by pesticides is a ubiquitous concern for wildlife. The effects of
pesticides are especially concerning in aquatic environments, which are particularly
vulnerable as they have several exposure routes for the influx of chemicals. These
effects are of particular concern as biodiversity loss reaches unprecedented rates. This
includes recent declines...
Humans have drastically altered the physical habitat and food web structure of stream ecosystems. Two major impacts humans have had on Pacific Northwest streams are modification of streamside forests (as a result of agriculture, land development, and timber harvest), and declines in the return of wild anadromous salmon to headwater...
The purpose of this research was to develop tools and germplasm for the production of tomatoes (Solanum lycopersicum L.) with high fruit phenolics without the use of genetic engineering.

Spotted wing Drosophila (SWD), Drosophila suzukii (Diptera: Drosophilidae), is a pest of small and stone fruits that is widely distributed across much of the United States, Canada, Europe and Asia. Unlike other members of the Drosophilidae that only lay eggs in overripe or rotting fruit, SWD infest ripening and ripe...
Alternative male phenotypes in salmonine fishes arise from individuals that mature as either larger and older anadromous marine-migrants or as smaller and younger freshwater residents. Variability in age and size of males at maturity is hypothesized to be preceded by early differences in growth in size and lipid storage. Water...
Steelhead and rainbow trout are common names for marine-migratory (anadromous) and freshwater-resident forms of Oncorhynchus mykiss, a partially migratory salmonid fish. Anadromous and resident forms are sympatric and can produce offspring with a life history different from their own (i.e., steelhead parents can produce rainbow trout offspring and vice versa)....
The global Cross-Laminated Timber (CLT) industry has changed dramatically within the past decade, with expansion outside of its start in Alpine Europe. The societal focus on more sustainable options within the built environment has led to an increased use of mass timber construction and its products including cross-laminated timber. Examining...
