Fusarium proliferatum is a fungus found in soils which produces the mycotoxin group known as fumonisins. Of human concern due to hepato-, nephro- and neurotoxicity, the threat of fumonisins lies within several food items, including corn, wheat sorghum, asparagus and, more recently, garlic. Manifesting as ““garlic rot”,” F. proliferatum infection...
Emerging data showing the presence of atmospheric microplastics (MPs) has recently raised awareness surrounding the potential of human nanoplastics (NPs) exposure. Due to factors such as weathering, UV exposure, and other biodegradation processes, plastic pollution in the environment breaks down over time into micro (<5 micrometers) and nanoscale (<1000nm) particles....

This paper examines how the Trinidadian diaspora currently residing in places like New York, Toronto or London’s are influenced by...
This article seeks to make a compelling case for authors’ rights training through emphasis on academic librarians’ dual roles as both authors and as liaisons to research and teaching faculty. Using the example of the Rights Well Workshop developed at Oregon State University Libraries, the article demonstrates the value of...
Students today perform research in a disintermediated environment, which often allows them to struggle directly with the process of selecting research tools and choosing scholarly sources. The authors conducted a qualitative study with twenty students, using structured observations to determine the processes students use to select databases and choose sources...
How are academic libraries organizing themselves in order to engage in the content selection and digitization of local collections? Are libraries creating new positions or units, assigning responsibilities to existing departments, setting up cross-functional collaboration among existing departments, or using a combination of these strategies? Who holds responsibility for the...
This paper asks whether animals can ever break out of anthropocentric value systems in literary narratives and, if so, what critical methods might be enlisted to reveal a literary animal’s independent agency. Examining the representation of a gray wolf in Cormac McCarthy’s novel The Crossing, it concludes that the animal’s...
Temperate forests play an important role in the global carbon cycle, and are thought to currently be a sink for atmospheric CO₂. However, we lack understanding of the drivers of forest carbon accumulation and loss, hampering our ability to predict carbon cycle responses to global change. In this study, we...

Oxygen uptakes of Douglas-fir beetles collected during November
1969 through April 1970 were measured at different experimental temperatures.
The oxygen uptakes of adult beetles increased at each
experimental temperature as the seasons progressed from winter to
spring.
The larval and pupal Douglas-fir beetles, collected in February
1970, had lower oxygen...
Many streams in eastern Oregon are listed as water quality impaired on the basis of water temperature. However, it is often difficult to predict water temperature for these streams even if there are no anthropogenic impacts. We measured air and water temperature and stream characteristics on three Type C and...
Due to its importance, the phenomenon of hydrogen
bonding has been the subject of much research over the
years. Among the different techniques used to study
hydrogen bonded systems, vibrational spectroscopy is
perhaps the most sensitive because of the striking
changes induced in molecular spectra by the formation of
hydrogen...
Radon-222 gas has unique properties allowing it to be used as an indicator for the
presence of organic phase liquids in the saturated zone. It naturally occurs in soils. It is
radioactive, making quantitative detection straight forward. A noble gas, it is chemically
inert and does not react with aquifer...
Tennyson and Hopkins scholarship is dominated by a focus on antithetical dichotomies. Tennyson's speakers are fractured selves focused on the gap between matter and spirit, faith and reason, solitude and community. Likewise, Hopkins' doubled vocation as priest and poet is presented as a contradiction to the point that the transition...
During extreme exercise, athletes experience increased inflammation that is similar to the acute phase response. Endurance athletes, distance runners in particular, are also more susceptible to compromised iron stores. This study evaluated inflammation, immune function and iron status in athletes completing a 50K ultramarathon. Twenty-two well-trained distance runners, 11 males...
Dietary excesses and imbalances play a prominent role in five of the ten leading causes of death in the U.S. Recognizing that many Americans tend to have poor dietary habits, the government has implemented several nutrition education strategies. Although these efforts have attempted to improve the nutritional status of Americans,...
The bark beetle Dendroctonus ponderosae Hopkins (Coleoptera:
Scolytidae) has caused severe mortality in recent decades to young
stands of ponderosa pine in the western United States. Insect parasites
and predators, believed to be of importance in the population
dynamics of the beetle, were the subject of the thesis research, conducted...
Behavioral responses exhibited by the Douglas-fir beetle,
Dendroctonus pseudotsugae Hopkins, to various attractant sources
were investigated under both laboratory and field conditions. Tests

Populations of Dendroctonus ponderosae Hopkins from three pine
hosts, Pinus ponderosa Laws., P. contorta Dougl. and P. monticola
Dougl., were sampled with regard to their acoustic signals, the
morphology of their stridulatory apparatus and some aspects of their
emergence behavior. Comparisons of these characteristics were made
between samples from different...
Landforms are natural features on the Earth’s surface that both reflect and shape geophysical and ecological process. The result is a defining part of landscapes that so often impact on human perception and interactions with environment. Blascyznki (1997) defines landforms as, “specific geomorphic features on the surface of the Earth,...
Six species of Cleridae, including Enoclerus spegeus Fabricius,
E. lecontei Wolcott, E. schaefferi (Barr), E. eximius Mannerheim,
Thanasimus undatulus Say, and an undescribed species of Enoclerus,
were found on Douglas-fir in western Oregon. E. sphegeus was the
only clerid of the six species studied which was primarily associated
with the...
Factors considered were phloem moisture, sour-phloem (which
may be furthered by the presence of ample phloem moisture), oleoresin of the host, and the presence of unmated female beetles in
suitable host material.
Levels of phloem moisture present in variously prepared logs
in the field ranged from about 100 to upwards...
