This publication identifies and describes the natural occurring plant associations within the central Oregon Pumice deposition zone. A dichotomous vegetation-site key is provided toward the front of the publication to assist administrators and field personnel in on-site identification of the associations. The descriptions are grouped according to similarities in dominant...
The study was conducted over approximately 191,000 acres in central Klamath County, Oregon. The research had three objectives: first, to describe and classify the seral and near-climax vegetation by using polyclimax principles; secondly, to determine the southern extension of five plant associations and one plant associes as previously described by...
A biosystematic study was made in seven populations of Mimulus
nanus Hook. & Arn. and M. cusickii (Greene) Piper (Scrophulariaceae)
in central Oregon, and a taxonomic revision was made of the four
species of section Eunanus reported from Oregon--M. nanus, M.
cusickii, M. clivicola Greenm. and M. jepsonii Grant. Mimulus...
The central part of the Bayhorse Mining District is located in the Salmon River Mountains in north-central Idaho between the towns of Challis and Clayton. The area is underlain by metasedimentary rocks of Early to Middle Paleozoic age that were profoundly affected by the emplacement of a plutonic complex in...

AN ABSTRACT OF THE THESIS OF
WADE ALLAN HODGES for the MASTER
This paper discussed the human electrocardiogram, the instrumentation
used to graphically record it, and the design and performance
of a specialized system for vector cardiography: the Vector Electrocardioscope
(VECS) System. The introduction reviews in considerable
detail the pertinent known physiology of the heart, especially the
electrophysiology responsible for the genesis...
We test hypothetical tsunami scenarios against a 4,600-year record of sandy deposits in a southern Oregon coastal lake that offer minimum inundation limits for prehistoric Cascadia tsunamis. Tsunami simulations constrain coseismic slip estimates for the southern Cascadia megathrust and contrast with slip deficits implied by earthquake recurrence intervals from turbidite...
As a key factor contributing to slope stability, in-stream habitat for aquatic species (e.g., salmonids), nutrient cycling, and corridors for upland species, riparian vegetation and its maintenance is of critical conservation importance. Subsequently, the chronic degradation of aquatic and riparian ecosystems in the semi-arid and arid landscapes of the western...
