Contextual systems description of an Oregon coastal watershed

Creator:: Goetze, Brigitte
Abstract:: Many resource management controversies indicate disagreement about the possible intended and unintended effects of management actions on ecosystems. Researchers have documented a variety of negative effects on specific ecosystems, e. g. the degradation of salmonid habitat due to mass wasting (Hagans et al. 1986). While the effects of some management...

Agricultural erosion and sediment in the western Willamette Valley as indicated by redistribution of Cesium-137

Creator:: Brown, R. B. (Randall Barber)
Abstract:: Modern agricultural erosion was studied using ¹³⁷Cs from fallout as an indicator of erosion/deposition. The study area was a 285 ha agricultural watershed in the hilly western margin of the Willamette Valley, a high winter rainfall zone in which fall-planted crops are commonly grown. Objectives of the study were (i)...

An investigation into modeling snow cover elements at Crater Lake National Park and surrounding environs as an improved "ground truth" method for satellite snow observations

Creator:: Hamilton, William L.
Abstract:: 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...

Understory response to tree harvesting in pinyon-juniper woodlands

Creator:: Everett, Richard L.
Abstract:: Understory species associations and their association with tree species were examined on three intensively studied stands. We studied the chronosequence of understory species associated with different aged singleleaf pinyon (Pinus monophylla Torr. and Frem.) trees. Mid- to late pinyon-juniper understory succession was found to be more spatial than floristic in...

A morphologic and morphometric analysis of the "Sorex vagrans species complex" in the Pacific Coast region

Creator:: Carraway, Leslie N.
Abstract:: Shrews of the "Sorex vagrans species complex" were classified into nine taxa on the basis of morphologic and morphometric analyses of 2,299 specimens from Washington, west of the Cascade Mountains in Oregon, and in the Coast Ranges of California. In Washington, Sorex monticolus setosus and S. m. obscurus occur west...

An analysis of trustee role perceptions in the state controlled Washington community college system and the locally controlled Oregon community college system and the relationship between trustee personal characteristics and these role perceptions

Creator:: Boyse, Peter Dent
Abstract:: This study examined the role perceptions of trustees in the locally controlled Oregon community college system and the state controlled Washington community college system. Authorities in the literature were consulted to define the "ideal trustee role" and the study determined which governance system was most effective in fostering this "ideal...

A molecular study of the viral proteins of infectious hematopoietic necrosis virus

Creator:: Hsu, Ya-li
Abstract:: The virion protein patterns of 72 isolates of infectious hematopoietic necrosis virus (IHNV) were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of S-methionine labeled virus. This analysis led to the classification of these virus isolates into 4 or more types. Type 1 virus is characterized by a nucleocapsid protein...
