Rodents are an increasing problem in fields and pastures. Birds of prey play a vital part in integrated pest management of rodent pests. This publication succinctly describes the value to farmers and ranchers of barn owls and American kestrels for rodent control, and ways to help build up local populations...
Sound and essential management practices, succinctly described, for maintaining a high quality, productive pasture and healthy livestock. The publication is primarily directed to eastern Oregon small acreage landowners.
Living on The Land — Managing Manure contains concise information on the basics of livestock manure management. Content includes handling, storage, composting, use, and ways to reduce negative effects on the environment. It particularly applies to the region east of the Cascade Mountains. Companion audio files include: The Scoop on...
We gathered baseline data to assess alder tree damage in western Oregon riparian ecosystems. We sought to determine if Phytophthora-type cankers found in Europe or the pathogen Phytophthora alni subsp. alni, which represent a major threat to alder forests in the Pacific Northwest, were present in the study area. Damage...
The Expanded Food and Nutrition Education program (EFNEP) helps limited income families in Oregon improve their nutrition practices. These include learning to: □ Stretch family food dollars □ Choose foods for better nutrition for family members □ Purchase food for nutritional needs □ Improve food production, preparation, storage, safety, and...
Background: Arsenic is an immunotoxicant. Clinical reports observe the reactivation of varicella zoster virus (VZV) in people who have recovered from arsenic poisoning and in patients with acute promyelocytic leukemia that have been treated with arsenic trioxide. Objective: We evaluated the association between arsenic and the seroprevalence of VZV IgG...
Several taxonomic issues in the moth families Erebidae and Noctuidae are addressed for Northwestern North America. Drasteria parallela Crabo & Mustelin and Cycnia oregonensis tristis Crabo in the Erebidae and Eudryas brevipennis bonneville Shepard & Crabo, Resapamea diluvius Crabo, Resapamea angelika Crabo, Resapamea mammuthus Crabo, Fishia nigrescens Hammond & Crabo,...
Diatom remains indicate the oceanic Ge/Si ratio (μmol/mol) has varied temporally, ranging from Miocene values of 0.9 to Last Glacial Maximum (LGM) values of 0.55, with the present value of 0.69. These ratios lie between those for the primary sources for these elements: continental weathering (Ge/Si = 0.5) and hydrothermal...
To quantify total fishing mortality it is necessary to incorporate mortality rates attributed to bycatch,
including animals that are discarded and that interact with the gear without being caught. The Reflex
Action Mortality Predictor (RAMP) approach has been increasingly used to determine bycatch mortality
rates in fisheries. This methodology creates...
Non-prescription stimulant use is a high-risk behavior prevalent in the college population. To date, research on this substance use behavior lacks a comprehensive theoretical lens, as well as geographical diversity. Guided by the Theory of Triadic Influence (TTI), multilevel (i.e. students within schools) modeling was used to analyze survey data...
A theory-guided instrument for examining prescription stimulant misuse in the college population was developed and its psychometric properties were evaluated from 2011-2012 at one Pacific Northwest (United States) university. Study methods included instrument development, assessment by five health and measurement professionals, group interviews with six college students, a test-retest pilot...
BACKGROUND: The illicit use of prescription stimulants (IUPS) has emerged as a high-risk behavior of the 21st century college student. As the study of IUPS is relatively new, we aimed to understand 1) characteristics of IUPS (i.e., initiation, administration routes, drug sources, motives, experiences), and 2) theory-guided intrapersonal, interpersonal, and...
The illicit use of prescription stimulants (IUPS) is a substance use behavior that remains prevalent on college campuses. As theory can guide research and practice, we provide a systematic review of the college-based IUPS epidemiological literature guided by one ecological framework, the Theory of Triadic Influence (TTI). We aim to...
BACKGROUND: Poorly ventilated combustion stoves and pollutants emitted from combustion stoves increase the risk of acute lower respiratory illnesses (ALRI) in children living in developing countries but few studies have examined these issues in developed countries. Our objective is to investigate behaviors related to gas stove use, namely using them...
This is the third publication in the Nutri-Kids series by the Expanded Foods and Nutrition Education Program (EFNEP) of Oregon. The federal program, administered by OSU Extension Services, offers nutrition education to low income adults and youth. Nutri-Kids Visit the Zoo (first grade materials) and Nutri-Kids Visit Goodeater Farm (kindergarten...
The Expanded Food and Nutrition Education program (EFNEP) helps limited income
families in Oregon improve their nutrition practices. These include
learning to:
□ Stretch family food dollars
□ Choose foods for better nutrition for family members
□ Purchase food for nutritional needs
□ Improve food production, preparation, storage, safety, and...
The objective of this study was to compare two techniques for estimating benthic fluxes of nutrients (nitrate, phosphate, and silicic acid) and Ge/Si flux ratios. In situ flux chambers were deployed, and cores were collected and incubated at 9 sites along the California margin in July 2001. Both techniques were...
Using a probability-based neighborhood sample of urban African American youth and a sample of their close friends (N = 202), we conducted a one-year longitudinal study to examine key questions regarding sexual and drug using norms. The results provide validation of social norms governing sexual behavior, condom use, and substance...
OBJECTIVE: To test a theory-driven model of health behavior to predict the illicit use of
prescription stimulants (IUPS) among college students. PARTICIPANTS: A probability sample of
554 students from one university located in California (response rate = 90.52%).
METHODS: Students completed a paper-based survey developed with guidance from the Theory...
Rockfishes, Sebastes spp.. were the most numerous and speciose fishes seen during 16 submersible dives from 64 to 305 m depth in the vicinity of Heceta Bank off the coast of Oregon. Dense schools of juvenile rockfishes and large yellowtail rockfish, S. flavidus, were observed only over rocky, high relief...
