As part of a hierarchical approach to classifying watersheds and stream habitats based on geomorphic and geologic criteria, we defined ten classes of fluvial and lacustrine habitats at the scale of valley segments. Valley segments are landscape units which encompass surface waters and the adjacent floodplains and hillslopes with which...
One of the goals of ecosystem management is to integrate management of many species and processes across a range of temporal and spatial scales. I investigated the relationship between small mammals and amphibians at 3 spatial scales. My objective
was to identify, habitat associations of forest floor vertebrates at the...
Streamflow forecasts are essential to the optimal operation of
hydroelectric and irrigation reservoirs in the Pacific Northwest.
Satellite snow cover observations would aid in these streamflow forecasts
by providing snow cover data at regular time intervals. Unfortunately,
satellite capability to remotely sense mountain snow cover
conditions is indeterminate due to...
The objectives of this study were to quantify and describe:
(1) the major plant communities and their distribution, (2) the
distribution and movement patterns of large herbivores relative to
water, topography, and plant communities, (3) the daily activity
patterns of each herbivore, and (4) the borne range size of wild...
Tracer-derived estimates of hydraulic resistance and transient hydraulic
storage were related to measures of pool volume and channel morphometric
variability in small streams of the Oregon coast, U.S.A. Fourteen
100 m study reaches in 3 streams were selected to compare channel
and hydraulic characteristics in streams representing a time series...
Pacific Coast band-tailed pigeons (Columba fasciata) have declined markedly
during the past several decades. Despite implementation of increasingly restrictive
hunting regulations, populations have shown minimal signs of recovery. I radio-marked
127 adult band-tailed pigeons in the central Oregon Coast Range in April-May of 1993-95
to document nesting chronology and productivity,...
The purposes of the study were to: 1) evaluate health knowledge competencies,
2) assess health skills, and 3) determine interrelationships among health knowledge,
health skills, and self-reported behavioral demographic variables for Oregon
entry-level college freshmen who had graduated from Oregon schools. An instrument,
the "Health Education Survey," was developed with...
