We are studying the impacts of parasites on threatened stocks of Oregon coastal coho
salmon (Oncorhynchus kisutch). In our previous studies, we have found high infections of
digeneans and myxozoans in coho salmon parr from the lower main stem of West Fork Smith
River (WFSR), Oregon. In contrast parr from...

The recent increase in awareness of the seismic hazards in Oregon has led to a concern regarding the safety of Oregon State University buildings. While the decision has been made to initiate the seismic rehabilitation of campus facilities, the question of which buildings pose the greatest hazards, and are therefore...

AN ABSTRACT OF THE THESIS OF
Steven R. Trautwein for the degree
Surface transient storage (STS) and hyporheic transient storage (HTS) have
functional significance in stream ecology and hydrology. Both provide refugia for aquatic
communities and their longer mean residence times (compared to the main flow) increase
the potential for biogeochemical reactions that can improve water quality. As STS and
HTS have...

A 5-year-old, male, domestic rabbit had severe swelling of the left rear leg. Radiographs demonstrated a proliferative, infiltrative lesion involving the stifle joint, femur, and soft tissues of the thigh. Osteomyelitis or neoplasia was suspected, and the leg was surgically amputated. Grossly, a multilobular mass comprised cyst-like structures containing yellow...

Invasions have increased the size of regional species pools, but are typically assumed to reduce native diversity.
However, global-scale tests of this assumption have been elusive because of the focus on exotic species richness,
rather than relative abundance. This is problematic because low invader richness can indicate invasion resistance by...

Although most eastern North Pacific (ENP) gray whales feed in the Bering, Beaufort,
and Chukchi Seas during summer and fall, a small number of individuals,
referred to as the Pacific Coast Feeding Group (PCFG), show intra- and interseasonal
fidelity to feeding areas from northern California through southeastern Alaska. We
used...

A wide variety of consumer products that are treated with poly- and perfluoroalkyl substances (PFASs) and related formulations are disposed in landfills. Landfill leachate has significant concentrations of PFASs and acts as secondary point sources to surface water. Here, we model how PFASs enter leachate using four lab-scale anaerobic bioreactors...

CodY is known to regulate various virulence properties in several Gram-positive bacteria but has not yet been studied
in the important histotoxic and intestinal pathogen Clostridium perfringens. The present study prepared an isogenic codY-null
mutant in C. perfringens type D strain CN3718 by insertional mutagenesis using the Targetron system. Western...
