Many cranberry growers on the Oregon coast are well aware that good pollination is necessary for quality fruit set. Multiple
visits to the flower deliver more pollen, which can increase the percentage fruit set, number of seeds per berry, and mature
berry weight. The better a bee is at delivering...
The decline of the Chinook Salmon has been a mystery of recent years due to their decline. It has been speculated that wild origin salmon have more vigor and survivability than hatchery reared fish. This is thought to be due to rearing conditions, possibly affecting sensory organ development. The sensory...

This study examines the ways in which community college transfer students develop a sense of belonging at the four-year institution. This inquiry was guided by a constructivist epistemology and qualitative methodology. Data was collected through conducting one-on-one interviews and focus groups to gather information on how transfer students develop a...
The purpose of this phenomenological study was to explore the lived experiences and understandings of professionals engaged in the interpretation of archaeological resources and heritage sites. The focus was on the examination of the experiences of professionals engaged in the interpretation of archaeological resources and their understandings of the following:...
Although the incidence of non-contact anterior cruciate ligament (ACL) injuries is greater among women than men athletes, the factors that contribute to this greater risk of injury are not well understood. One relevant question is whether decision making during landing influences the biomechanical and neuromuscular factors thought to contribute to...
The effect of anthropogenic disturbance on river systems is gaining attention, and concerns about the state of freshwater natural resources are increasing globally, as are efforts to restore habitat that has been degraded by disturbance. In rivers, non-point source pollution affects the physical characteristics of the habitat and the endemic...
This research focuses on the economic and social impacts to women’s and children’s dental health after methamphetamine abuse. Family oral health status, access to professional services, health literacy and home hygienic practices are evaluated in the frameworks of critical medical anthropology, applied anthropological praxis and matrix and bio-psycho-social addiction models...
Captive rearing programs (hatcheries) are often used in conservation and management efforts
for at-risk salmonid fish populations. However, hatcheries typically rear juveniles in environments
that contrast starkly with natural conditions, which may lead to phenotypic and/or genetic changes that adversely affect the performance of juveniles upon their release to the...

From 26 March – 19 September 2013 we monitored the distribution, abundance and productivity of the federally Threatened Western Snowy Plover (Charadrius nivosus nivosus) along the Oregon coast. From north to south, we surveyed and monitored plover activity at Sutton Beach, Siltcoos River estuary, the Dunes Overlook, North and South...
In 2002, the Biscuit Wildfire burned a portion of the previously established,
replicated conifer unthinned and thinned experimental units of the Siskiyou Long-Term
Ecosystem Productivity (LTEP) experiment, southwest Oregon. Charcoal C in pre and
post-fire O horizon and mineral soil was quantified by physical separation and a
peroxide-acid digestion method....
One common assumption in interpreting ice-core CO₂ records is that diffusion in the ice does not affect the concentration profile. However, this assumption remains untested because the extremely small CO₂ diffusion coefficient in ice has not been accurately determined in the laboratory. In this study we take advantage of high...
Disasters result from hazards affecting vulnerable people. Most disasters research by anthropologists focuses on vulnerability; this article focuses on natural hazards. We use the case of wildfire mitigation on United States Forest Service lands in the northwestern United States to examine social, political, and economic variables at multiple scales that...
