Since 2001, librarians at Oregon State University’s Valley Library have been working to build a “teaching library” supported by a clearly articulated instruction program. From the start, we believed that we needed to assess the “teaching library’s” impact, not only to determine the success or failure of our efforts but...
Hydraulic conductance of leaves (K[subscript leaf]) typically decreases with increasing water stress and recent studies have proposed different mechanisms responsible for decreasing K[subscript leaf]. We measured K[subscript leaf] concurrently with ultrasonic acoustic emissions (UAEs) in dehydrating leaves of several species to determine whether declining K[subscript leaf] was associated with xylem...

(Lepidoptera: Tortricidae), in apple, Malus domestica Bordk. The treatments involved the use of clear, orange, and white traps baited with one or more of the following attractants: the major...
OBJECTIVE: Pharmacokinetic interactions exist between combined
oral contraceptives and protease inhibitors (PI). However, such
information is lacking for progestin-only oral contraception. We
sought to define the steady-state pharmacokinetic interaction between
norethindrone (NET) and PI in HIV-infected women.
METHODS AND DESIGN: We conducted an open-label, prospective,
nonrandomized trial to characterize the...
In Kentucky bluegrass (Poa pratensis), Claviceps purpurea, the causal agent of ergot, typically releases ascospores during the early-morning hours, between about midnight and 10:00 A.M., corresponding to time of flowering, when the unfertilized ovaries are most susceptible to infection. During aeromycology studies of C. purpurea in perennial ryegrass (Lolium perenne)...

The production of novel hybrid zones is an ecologically important consequence of globally increasing rates of species introductions and invasions. Interspecific hybridization can facilitate gene flow between parent species or produce novel taxa that may alter invasion dynamics or ecosystem services. The coastal sand dunes of the U.S. Pacific Northwest...
The adaptive capacity of marine calcifiers to ocean acidification (OA) is a topic of great interest to evolutionary biologists and ecologists. Previous studies have provided evidence to suggest that larval resilience to high pCO2 seawater for these species is a trait with a genetic basis and variability in natural populations....
Balancing selection is one of the mechanisms which has been proposed to explain the maintenance of genetic diversity in species across generations. For species with large populations and complex life histories, however, heterogeneous selection pressures may create a scenario in which the net effects of selection are balanced across developmental...
Trust is a key variable for successful natural resource management and is commonly the focus of conceptual and methodological development. Distrust, on the other hand, is frequently cited as an obstacle to management, but appears to be rarely defined, conceptually underdeveloped, and inconsistently examined.
