Carp, Climate, and Water Quality: Applying Systems Modeling to Ecosystem Recovery in Malheur Lake

Creator:: Pearson, James B.
Abstract:: Shallow lakes exist in either a clear or turbid state, with the clear state characterized by an abundance of aquatic macrophytes, diverse aquatic biota, low water column nutrients and phytoplankton biomass, whereas the turbid state is characterized by the opposite. These two distinct states are maintained by reinforcing (positive) feedback...

Responses of juvenile coho salmon and larval lamprey to instream habitat restoration in a Pacific Northwest stream

Creator:: Gonzalez, Rosalinda
Abstract:: Large wood has been utilized in many restoration projects to improve in-stream habitat in the Pacific Northwest for salmon. However, the benefits of this practice remain the subject of ongoing debate and evaluation of these projects has scarcely been done for non-salmonid species such as lamprey. In this study we...

Early maturing males in a partially migratory population of anadromous and resident rainbow trout Oncorhynchus mykiss: influences of individual condition and stream temperature

Creator:: McMillan, John R.
Abstract:: Alternative male phenotypes in salmonine fishes arise from individuals that mature as either larger and older anadromous marine-migrants or as smaller and younger freshwater residents. Variability in age and size of males at maturity is hypothesized to be preceded by early differences in growth in size and lipid storage. Water...

Where the Stream Meets the Road : Prioritizing Culvert Replacement for Fish Passage

Creator:: Reagan, Rachel E.
Abstract:: Streams across the world are highly fragmented due to the presence of in-stream barriers (e.g., dams and stream-road crossings), many of which restrict or block fish passage. Retrofitting or replacing these structures is a high priority for restoring habitat connectivity for native fishes and other aquatic organisms in the Pacific...

Guidelines for developing a community college teacher education program in Oregon

Creator:: Dunham, Daniel Bentley
Abstract:: The primary purpose of this study was to develop guidelines for planning a preservice preparation program which would encompass the critical issues in community college teacher education identified in the related literature and by national and state authorities. The secondary purpose was to suggest a plan for a community college...

Douglas-fir hydraulic architecture and relationships among xylem properties at multiple scales via a Bayesian analysis

Creator:: Dunham, Sonya M.
Abstract:: This study investigated variation in xylem anatomy, hydraulic properties, and the relationship between anatomy and properties within Douglas-fir trees at multiple scales. The hierarchical scales in the study included fertilization treatments (fertilized and unfertilized), trees within the treatments, and positions within the trees. Tracheid diameter, tracheid length, percent latewood, number...

Annotated Bibliography of Research Focused on 1st-3rd Order Pygmy Rabbit (Brachylagus idahoensis) Habitat Selection

Creator:: Jencso, Emily D.
Abstract:: Wildlife managers often use species distribution models (SDMs) as an initial tool in conservation planning. Managers and researchers have made efforts to model the habitat and distribution of pygmy rabbits (Brachylagus idahoensis) across their historic range since the species was proposed for listing under the Endangered Species Act (USFWS 2003)....

Description and prediction of broad-scale spatial variability in expression of anadromy in female Oncorhynchus mykiss in the John Day River, Oregon, USA

Creator:: Mills, Justin S.
Abstract:: Partial migration is a common migratory behavior where some individuals in a population migrate and others do not. Patterns of partial migration can vary dramatically, especially for species that inhabit a wide range of environments. I described and predicted spatial variation in marine migration (anadromy) of female Oncorhynchus mykiss (steelhead...
