3) The standard deviations of the SST anomalies in the HadISST1.1 dataset are 0.2–0.4°C smaller prior to 1949 than after 1949. This nonstationarity could complicate interpretations of the long HadISST1.1 data record for some studies of climate variability. It is likely attributable mostly to the improved sampling of SST observations...
This study explored how micro-credit benefits women processing cultured catfish into smoked form by obtaining and analyzing their perceptions. The specific objectives included identifying micro-credit sources used, sources preferred and ranking factors considered when deciding on a micro-credit choice. Multi-stage sampling technique was used in selecting 120 processors analyzed. Analytical...
Over 70% of the Antarctic krill population exists along the Antarctic Peninsula, a region undergoing rapid climate change. Recent studies have shown a clear correlation between krill recruitment each spring and the timing and coverage of sea ice the winter before, with less sea ice and a shorter duration being...
The Forest Elevation Snow Transect (ForEST) project is a paired site elevational snow study. It is designed to measure how snow accumulates and ablates under different forest structures across an elevation range. The ForEST project has been ongoing since the winter of 2011-2012 within the McKenzie River Basin of the...
The SLICES framework is intended for use in making decisions about conservation and restoration in the Willamette River floodplain. It makes use of distinct spatial units, called slices, for planning and tracking change in the floodplain. The first of these units are 1 kilometer long slices drawn at right angles...
Wildfire risk in temperate forests has become a nearly intractable problem that can be characterized as a socioecological “pathology”: that is, a set of complex and problematic interactions among social and ecological systems across multiple spatial and temporal scales. Assessments of wildfire risk could benefit from recognizing and accounting for...
An understanding of fishers' decisions to exit or stay in a fishery is important for developing effective policy measures. In this study, we analyze the factors influencing this decision using a large administrative database covering the entire Swedish fisher population, their family ties, and detailed labour market data spanning two...
We investigate how individual preferences affect noncompliance in fisheries. We use data from a combined web-based experiment and survey of Norwegian fishermen to empirically analyze this. In the economic experiment, the participants won real money in a set of lotteries based on their answers and lottery outcomes. Based on the...

Individual quota (IQ) management systems in commercial marine fisheries are highly diverse, differing in the security, durability and exclusivity of the harvesting privilege and the transferability of quota units. This diversity in the degree of harvest rights may influence the effectiveness of IQ fisheries to meet management objectives. We conducted...
The forest sector and the global financial crisis (GFC) provide a unique setting for investigating the relationships among market orientation, innovativeness and firm performance. While most of the extant literature suggests that market orientation helps a firm build its innovativeness, we suggest that in the production oriented forest sector, especially...
This document provides an overview of a presentation held during the Industry and Policy Day at the IIFET 2016 Scotland conference in July 2016. The presentation was part of Session A3: Reformed CFP - Implications for Routes to Market. The session was chaired by Marcus Coleman, and the presentation was...
On March 31, 2016 the Oregon State University Postdoctoral Association and the Oregon State University Libraries hosted an open access panel moderated by Pedro Molina-Sanchez. Speakers included Michaela Willi Hooper, Scholarly Communication Librarian at OSU Libraries; Rachael Kuintzle, PhD student in the OSU College of Science; Marit Bovbjerg, Faculty in...
The interplay of natural selection and genetic drift, influenced by geographic isolation, mating systems and population size, determines patterns of genetic diversity within species. The sperm whale provides an interesting example of a long-lived species with few geographic barriers to dispersal. Worldwide mtDNA diversity is relatively low, but highly structured...
This report summarizes vegetation data collected in July 2015 in wet meadow and marshy habitats on the Double O Unit of Malheur National Wildlife Refuge (MNWR). Because vegetation sampled at the Double O was wetter and more alkaline than wet meadows sampled at the south end of the refuge in...
Relatively little is known about aboveground nutrient content of organic blackberry, and there is no published work on total carbon (C) content. Treatment effects on biomass, C, and nutrient content, accumulation, and removal were assessed over 2 years in a mature organic trailing blackberry (Rubus L. subgenus Rubus, Watson) production...
Organic production of blackberries is increasing, but there is relatively little known about how production practices affect plant and soil nutrient status. The impact of cultivar (Black Diamond and Marion), weed management (nonweeded, hand-weeded, and weed mat), primocane training time (August and February), and irrigation (throughout the summer and none...
The spatio-temporal overlap of morphologically undistinguishable weak and healthy stocks is a major concern for the Pacific Northwest troll Chinook salmon fishery. Regular fishery closures have led to major financial losses calling for alternative regulatory measures. One approach for such complex and pressing socio-ecological challenges is the transition towards transdisciplinary...
Observations of winds, waves, and turbulence at the ocean surface are compared with several analytic formulations and a numerical model for the input of turbulent kinetic energy by wave breaking and the subsequent dissipation. The observations are generally consistent with all of the formulations, although some differences are notable at...
Sharing of research data has begun to gain traction in many areas of the sciences in the past few years because of changing expectations from the scientific community, funding agencies, and academic journals. National Science Foundation (NSF) requirements for a data management plan (DMP) went into effect in 2011, with...
This is PMEL Contribution 4396.
Acidification has sparked discussion about whether regulatory agencies should place coastal waters on the Clean Water Act 303(d) impaired water bodies list. Here we describe scientific challenges in assessing impairment with existing data, exploring use of both pH and biological criteria. Application of pH criteria...
The global terrestrial carbon sink offsets one-third of the world’s fossil fuel emissions, but the strength of this sink is highly sensitive to large-scale extreme events. In 2012, the contiguous United States experienced exceptionally warm temperatures and the most severe drought since the Dust Bowl era of the 1930s, resulting...

Previous studies of coral viruses have employed either microscopy or metagenomics, but few have attempted to comprehensively link the presence of a virus-like particle (VLP) to a genomic sequence. We conducted transmission electron microscopy imaging and virome analysis in tandem to characterize the most conspicuous viral types found within the...
