The California Current Large Marine Ecosystem
(CCLME), a temperate marine region dominated by episodic
upwelling, is predicted to experience rapid environmental
change in the future due to ocean acidification. The aragonite
saturation state within the California Current System is
predicted to decrease in the future with near-permanent undersaturation
conditions expected...
Upper ocean hydrography in the central Arctic Ocean
has relaxed since 2000 to near-climatological conditions
that pertained before the dramatic changes of the 1990s. The
behavior of the anomalies of temperature and salinity in the
central Arctic Ocean follow a first-order linear response to
the AO with time constant of...
The coronavirus pandemic and its associated public health response resulted in disruptions in daily life as well as financial and other insecurities. This corresponded with an increase in adverse mental health outcomes in adolescents in the United States, including a temporary increase in suicidal ideation and behaviors. The pandemic also...
The focus of this single-site case study was to explore how rural dispersed Hispanic-serving community colleges in the Pacific Northwest support the development of Hispanic-Serving initiatives and strategies. The conceptual frameworks of Latino critical theory and the multicultural organizational development model were used to analyze and interpret the data. Interviews...
Many trace elements (e.g., Zn, Cd, Mo) are essential phytoplankton micronutrients, making them crucial to the marine ecosystem and ultimately the carbon cycle. Because of this association trace metals are also utilized in paleoceanographic studies (e.g., Mo, Cd). However, not much is known about what controls the cycling of these...
This study sought to better understand the voluntary adoption of water quality improving practices by agricultural producers in Northern Malheur County, Oregon. The Reasoned Action Approach/Theory of Planned Behavior was used as a theoretical framework to identify barriers and incentives to adoption. Study findings suggest that producers primarily consider practical...
The morphology and ecological importance of habitats associated with the margin of third-order stream channels in the Oregon Cascades were studied in streams in three different riparian types: 450-year-old conifers, 40-year-old alder, and an open, herbaceous-dominated clearcut. Margins, backwaters, and side channels in streams create important habitat for fry of...
Cydia latiferreana Wlshm. is recognized as the key
insect pest of cultivated filbert (hazelnut) in Oregon.
The purpose of this study was to obtain information on
mating and oviposition behavior of the adult insect, to
calculate the lower temperature threshold and degree-days
required for egg development, and to develop an...
A gas-permeable-membrane-supported (GPMS) biofilm consisting
of methylotrophic bacteria was effective in degrading chlorinated
methanes, ethanes, and ethenes. The biofilm was developed on a
gas-permeable fabric (Goretex, W.L.Gore & Associates, Elkton,
Maryland) that divided a reactor vessel into a liquid compartment
and a gas compartment. Goretex is a nylon-backed teflon mesh...
