Spawning, larval recruitment, and early life survival of Pacific lampreys in the South Fork Coquille River, Oregon

Creator:: Brumo, Abel F.
Abstract:: Recently, there has been concern over the decline of the Pacific lamprey, Lampetra tridentata, in the northwestern United States. However, effective management has been impeded by data gaps in basic biology, especially in the early life stages. Consequently, in 2004 and 2005 I examined reproductive ecology, larval recruitment, and lamprey...

Neural gene expression profiling in chinook salmon (Oncorhynchus tshawytscha) of alternate run times

Creator:: Bernier, Jeremiah C.
Abstract:: Chinook salmon (Oncorhynchus tshawytscha) display the greatest variability of return times to freshwater of all Pacific salmon. Differential return times to freshwater have segregated populations of Chinook into two broad types or runs, fall and spring, named for the time of year in which they migrate to freshwater. Migration time...

Using Oregon trawl logbooks to study spatial and temporal characteristics of commercial groundfish species associations

Creator:: Lee, Yong Woo
Abstract:: Species associations of fifteen major commercial groundfish species in the northeastern Pacific ocean and their spatial and temporal characteristics were studied using Oregon bottom trawl logbook data, 1987 to 1993. Screening procedures were used to remove questionable data from the original logbook files, which resulted in the exclusion of information...

Identification of candidate genes for survival and their use in predicting field performance of Pacific oyster Crassostrea gigas families in coastal waters

Creator:: Lang, Robert Paul
Abstract:: Summer mortality of farmed Pacific oysters causes financial losses for shellfish growers, and selective breeding to improve survival of offspring is a promising way to reduce losses. This dissertation has two objectives to assist the development of tools for use in selective breeding programs. Objective 1: Identify candidate genes for...

A macroscopic to microscopic study of the effects of barotrauma and the potential for long-term survival in Pacific rockfish

Creator:: Pribyl, Alena L.
Abstract:: Depleted species of rockfish (Sebastes spp.) from the Northeast Pacific experience high discard mortality due to "barotrauma," induced from the rapid change in pressure during capture. Research suggests rockfish have the potential to survive barotrauma if immediately recompressed, but the potential for long-term recovery is unknown. In this project, we...

The effects of environmental stressors on cardiac gene expression and contractility in rainbow trout (Oncorhynchus mykiss)

Creator:: Momoda, Tracey S.
Abstract:: Rainbow trout (Oncorhynchus mykiss) experience a variety of stressors in their natural environment as well as in aquaculture that can have negative effects on their physiology. The effects of physiological stress and endocrine disruption have been well described in fish. However, there is a scarcity of information on the effects...

Using parasite community data and population genetics for assessing Pacific sardine (Sardinops sagax) population structure along the west coast of North America

Creator:: Baldwin, Rebecca E. B.
Abstract:: Pacific sardines (Sardinops sagax) are an economically and ecologically important forage fish which transfer energy from planktonic primary producers and secondary consumers to upper trophic predators. Previous genetics studies of Pacific sardine suggested a panmictic population with a shallow genetic structure. However, more than one subpopulation within the Central California...

It’s in Their Bones: Ecological Drivers of Kemp’s Ridley Sea Turtle (Lepidochelys kempii) Somatic Growth and Population Dynamics

Creator:: Ramirez, Matthew D.
Abstract:: Somatic growth variation manifests from the cumulative effects of a suite of biological, ecological, and environmental processes and can have profound effects on individual fitness and species population dynamics. As ectotherms whose growth dynamics are greatly influenced by environmental factors, sea turtles display considerable variation in somatic growth within and...

Sequential isotopic analysis to characterize ontogenetic shifts and growth dynamics of loggerhead sea turtles (Caretta caretta)

Creator:: Ramirez, Matthew D.
Abstract:: Ontogenetic niche theory predicts that as organisms grow they make size-specific changes in habitat use and diet to optimize growth and survival. A variety of factors contribute to growth and survival in different habitats, ultimately leading to variation in life history that can affect population dynamics. An understanding of the...
