significant differences between the three groups of teachers: (1)
Mentor-Teacher Program interns (G.T.A.'s), (2) outstanding O.S.U.

Comparatively little work has been done to determine the ecology
of Clostridium botulinum type E since its initial isolation in the
nineteen-thirties. This spore forming, anaerobic microorganism is
relatively heat labile and has been missed in ecological surveys in
which heat was used to selectively screen for spore formers. Use...

Fire severity is hypothesized as an important driver of bird responses to wildfire. For those species that typically respond negatively to increasing severity, Accessibility of high-severity burned forest may be dependent on the proximity of unburned or low-severity burned forest to meet all of the needs of breeding bird species...
Riparian areas in the Pacific Northwest provide important biotic and abiotic
features, such as down wood, moist microsites, and abundant invertebrate prey that
benefit aquatic and terrestrial amphibians. Reported high densities of amphibians from
streams and riparian areas in the Pacific Northwest highlight their importance in riparian
food webs. Amphibians...
As the western United States faces warmer and increasingly varied climate conditions, as well as predicted water insecurity, concerns over water quality and water availability are growing. While humans, fish, and wildlife are dependent on clean water for survival in the present, management of water resources needs to consider future...
Background. The prevalence of pediatric dental caries (PDC) is 55.7% nationally, 52% in Oregon, and 73% in Southeastern Oregon. We examined prevention programs, clinical services, and water fluoride levels in Southeastern Oregon to understand the high PDC prevalence.
Methods. We conducted telephone surveys and used secondary data to assess water...
