Vegetation and Small Mammal Responses to Western Juniper (Juniperus occidentalis) Control in Eastern Oregon

Creator:: Morozumi, Corinne N.
Abstract:: Shrub-steppe ecosystems of western North America provide habitat for many wildlife species, are important components of public and private rangelands, and offer recreational opportunities for millions of people. They are some of the most vulnerable ecosystems in the United States and have been altered by human activities such as livestock...

Aspects of comparative neuromuscular physiology and pharmacology of black bass (Micropterus salmoides) as evidenced by the action of diisopropylfluorophosphate

Creator:: Schneider, Phillip William
Abstract:: Neuromuscular physiology has been extensively investigated in several groups of vertebrates excluding fish. To understand the nature of neuromuscular transmission in this group, the response of the pectoral fin abductor muscle of black bass (Micropterus salmoides) to nerve stimulation under the influence of an anticho1inesterase agent was studied. Diisopropylfluorophosphate (DFP),...

The Effects of Tank Structure and Egg Size on the Production of Wild Steelhead (Oncorhynchus mykiss) Surrogate Fish

Creator:: Self, Katharine E.
Abstract:: One of the biggest hurdles for a juvenile salmonid (Oncorhynchus mykiss) is migrating downstream from freshwater spawning grounds to the ocean. Juveniles from wild broodstock were reared from the South Santiam River for more than 1 year at the Oregon Hatchery Research Center (OHRC) in Alsea, OR. The fish were...

Body Condition and Hormone Assessment of Eastern North Pacific Gray Whales (Eschrichtius robustus) and Associations with Ambient Noise

Creator:: Lemos, Leila S.
Abstract:: Anthropogenic activities have posed many threats to the oceans and marine life. Understanding how individuals are affected and physiologically respond to these threats is crucial and allows for management and conservation applications. I evaluated the overall health condition of a subpopulation of gray whales (Eschrichtius robustus) along the Oregon coast,...

Local weather, regional climate, and population dynamics of northern spotted owls in Washington and Oregon

Creator:: Glenn, Elizabeth M.
Abstract:: Since the early 1990s, declines in northern spotted owl (Strix occidentalis caurina) populations have been documented through extensive field surveys and range-wide demographic analyses. Although loss of late-successional forest has been credited as the primary cause for spotted owl population declines, environmental variation has also been shown to influence vital...

Fine scale foraging behavior of gray whales in relation to prey fields and vessel disturbance along the Oregon Coast

Creator:: Sullivan, Florence A.
Abstract:: The desire to understand the spatial and temporal drivers of animal behavior and distribution relative to scale is central to movement ecology. Optimal foraging theory states that a predator should continue exploiting a patch until it is no longer profitable to do so. As human developments increasingly encroach on the...

Big Fishery, Big Data, and Little Crabs: Using a Genomic Approach to Examine Larval Recruitment Patterns of Dungeness Crab (Cancer magister) in the California Current Ecosystem

Creator:: Lee, Elizabeth M. J.
Abstract:: The California Current Ecosystem (CCE) is a dynamic marine ecosystem from which many socioeconomically important fisheries species are harvested. In this thesis, a genotyping-by-sequencing (GBS) approach was used to examine genomic variation in an early life stage of the Dungeness crab (Cancer magister), which constitutes the most valuable single-species commercial...

Cortisol and the immune system of juvenile Pacific salmon during stress and development

Creator:: Maule, Alec G.
Abstract:: Plasma concentrations of cortisol, a glucocorticoid hormone that is immunosuppressive in mammals, increase during stress and smoltification of salmonids. There was a reduction in the ability of lymphocytes to generate antibody producing cells (APC) in vivo concurrent with increased plasma cortisol titers during smoltification of coho salmon (Oncorhvnchus kisutch). Cortisol...

Landscape-Level Approaches to Desert Bighorn Sheep (Ovis canadensis nelsoni) Conservation in a Changing Environment

Creator:: Creech, Tyler G.
Abstract:: Landscape characteristics can strongly influence demographic and genetic processes in wildlife populations. Climate change and human land use are causing many landscapes to change rapidly, and the effects on wildlife populations must be understood to properly manage these threats and design effective conservation strategies. In this dissertation, I explored the...

Worldwide phylogeography and local population structure of the rough-toothed dolphin (Steno bredanensis)

Creator:: Albertson, G. Renee
Abstract:: Several dolphin species have global distributions. The extent of their radiation and limits to gene flow are presumably a product of oceanographic features both recent and historical, behavioral specializations and social organization. Rough-toothed dolphins (Steno bredanensis) are globally distributed in tropical and subtropical waters and are generally found in depths...
