The City of Florence, local stakeholders, and partner agencies recently formed the Siuslaw Estuary Partnership (SEP) to address threats to drinking water quality and fish and wildlife habitat in the lower Siuslaw watershed. The Sole Source Dunal Aquifer within the lower Siuslaw watershed, which supplies the City ’s drinking water,...

“Perennial ryegrass staggers” is a neurological condition characterized by muscular tremors and ataxia in livestock that ingest the indole diterpene lolitrem B from endophyte-infected perennial ryegrass. While the neurotoxic mechanism of action of ryegrass staggers has been defined, little is known about metabolic and other molecular processes that lolitrem B...
The conservation of declining desert fish species requires the identification of relations between fish population dynamics and their environments. Dynamic occupancy modeling, an approach that requires less information than traditional mark-recapture studies, may help identify important factors affecting population processes and aid desert fish conservation and restoration efforts. I used...
Lesser quadriceps explosive strength following anterior cruciate ligament (ACL) reconstruction (ACLR) may result in the use of altered landing mechanics that increase the risk for a second ACL injury. Reduced capacity to produce explosive strength in the quadriceps is potentially driven, at least in part, by quadriceps arthrogenic muscle inhibition...
Observations of temperature, winds, and atmospheric trace gases suggest that the transition from troposphere to stratosphere occurs in a layer, rather than at a sharp ‘‘tropopause.’’ In the tropics, this layer is often called the ‘‘tropical tropopause layer’’ (TTL). We present an overview of observations in the TTL and discuss...
Nitrogen is one of the major nutrients limiting microbial productivity in the ocean, and as a result, most marine microorganisms
have evolved systems for responding to nitrogen stress. The highly abundant alphaproteobacterium “Candidatus
Pelagibacter ubique,” a cultured member of the order Pelagibacterales (SAR11), lacks the canonical GlnB, GlnD, GlnK, and...

Women are highly-underrepresented in undergraduate engineering majors, making up just over 15% of students in engineering and computer science at Oregon State University. High school girls' interest in pursuing engineering in college is affected by the way language frames engineering careers. The status-quo engineering frame is made up of terms...
