Development and application of steelhead (Oncorhynchus mykiss) kelt identification techniques

Creator:: Evans, Allen F.
Abstract:: The migrations upstream of pre-spawned adult steelhead (Oncorhynchus mykiss) and downstream of post-spawned steelhead (referred to as "kelts") can geographically and temporally overlap in the Snake River, leading to management challenges for populations listed under the Endangered Species Act (ESA). This thesis describes the development and application of a method...

Effects of o,p'-DDE on the immune system of juvenile chinook salmon (Oncorhynchus tshawytscha)

Creator:: Milston, Ruth Helen
Abstract:: Environmental factors such as chemical contamination can have immunomodulatory effects on the immune response of fish and may be contributing to the decline in salmonid populations by augmenting disease susceptibility. Xenobiotics can interfere with the immune system at several levels of complexity, and different immune cells and processes have variable...

Effects of acute stress and tagging on the swimming performance and physiology of Pacific lampreys (Lampetra tridentata)

Creator:: Close, David A.
Abstract:: Pacific lampreys (Lampetra tridentata) have declined in abundance in the Columbia River Basin. Although, the reasons for the decline are unclear, we suggest that development of hydroelectric dams and habitat alterations in tributaries as the main causes. The available knowledge of life history of Pacific lampreys and status from dam...

Bioinformatics applied to freshwater cyanobacterial blooms and cyanophage

Creator:: Schwartz, Andrew D.
Abstract:: Freshwater cyanobacterial blooms are a nuisance and health threat in the Pacific Northwest. The accepted methods of characterizing these blooms by microscopic cell counts cannot differentiate between toxic and non-toxic strains of the cyanobacterium Microcystis. Also, there is limited understanding of freshwater cyanophage that may control bloom dynamics. In order...

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...

Involvement of the Ets-1 transcription factor in early bovine and porcine embryo development

Creator:: Stauber, Leah
Abstract:: Early embryo development is dependent on maternally derived RNA and protein synthesized during oogenesis. In the bovine embryo this dependence lasts until the 8-16 cell stage, at which time embryonic transcripts become essential for continued development. One proposed mechanism for this transition from maternal to zygotic control of development (maternal...

Reproductive biology and behavior of the brown tree snake (Boiga irregularis) on Guam.

Creator:: Waye, Heather L.
Abstract:: While there are many more species of reptiles in the tropics than in temperate latitudes, relatively little is known about the natural history of tropical species of snakes. Even basic information, such as reproductive ecology and behavior, is lacking. Patterns of reproduction in tropical species differ from patterns in temperate...

Biochemical and physiological indicators of behavioral impairment in salmonids exposed to chlorpyrifos and copper

Creator:: Sandahl, Jason
Abstract:: The purpose of this work was to determine if environmentally-relevant concentrations of chlorpyrifos and copper, two commonly detected chemicals in Western surface waters, can negatively impact the biological health of salmonids. Both compounds are highly neurotoxic to fish, but each with distinct biological target sites and mechanisms of action. We...

Playing by the Rules: A Formal Specification of BoGL’s Loops and Type System

Creator:: Grejuc, Alex
Abstract:: BoGL is a programming language created for the purpose of computer science education that is specific to the domain of board games. Although there is a language grammar and an existing implementation that is currently used by students, a complete and formal language standard does not yet exist. In the...

Potential of eradicating noxious weed seeds from the soil with heat and carabid seed predators

Creator:: Marshall, Nicole S.
Abstract:: The goal of this project was to develop and test non-herbicidal techniques that remove nonnative plant or weed seeds from the top 2 inches of the soil. The Nature Conservancy (TNC) is currently restoring prairies in the Willamette Valley. Some areas of the Pacific Northwest have already seen loss of...
