Spatial and temporal scales of genetic change in two overfished rockfishes

Creator:: Gomez-Uchida, Daniel
Abstract:: Pacific rockfishes (genus Sebastes) have attracted wide scientific and public interest from an evolutionary, fishery and conservation standpoints. This dissertation addresses several hypotheses involving spatial and temporal scales of genetic change in two overfished rockfishes, darkblotched (S. crameri) and canary rockfish (S. pinniger), using statistical analyses of genetic variation within...

Development of a progeny marker for steelhead

Creator:: Shippentower, Gene E.
Abstract:: This study was undertaken to determine if strontium chloride could be used to create a trans-generational otolith mark in steelhead (Oncorhynchus mykiss). I completed two strontium injection trials and a survey of juvenile steelhead from various steelhead hatcheries. The two trials measured Sr:Ca ratios in otoliths in response to injections...

Crystal Records of the Origin, Evolution, and Thermal Histories of Magmas

Creator:: Bradshaw, Richard W., 1985-
Abstract:: In volcanic systems, magma is generally stored in the shallow crust prior to eruption. The conditions of this storage directly impact whether the magma eventually erupts, or crystallizes within the crust to form a pluton. In this dissertation I present four studies that investigate the storage conditions of a number...

Dynamics of a long-lived magmatic system as indicated by variations in amphibole composition and textures in dacites erupted over 11 M.y. at the Aucanquilcha Volcanic Cluster, Central Andes, Chile

Creator:: Giles, Denise E. L.
Abstract:: The Aucanquilcha Volcanic Cluster (AVC) is the erupted part of a magmatic system with a complex and long-lived history. The AVC lies at 21°S in the high Andes and is built on thick continental crust. The thick crust in the area combined with the prolonged magmatic activity make it an...

The origin of mid-ocean ridge basalts : insights from trace element contents in anorthite, anorthite-hosted melt inclusions, and ocean core complexes

Creator:: Weinsteiger, Allison B.
Abstract:: The primary goal of this study is to access the processes that alter primary melts after segregation from a mantle source and ultimately form petrologic Layers 2 and 3 of the Ocean Crust. Mineral, melt inclusion, and whole rock chemical compositions are utilized to further the understanding of 1) the...

Isolation and Pathogenicity of Naturally Occurring Entomopathogenic Fungi to Clover Root Borer (Coleoptera: Curculionidae: Scolytinae), a Pest of Red Clover Seed Crops

Creator:: Lestari, Anis S.
Abstract:: Entomopathogenic fungi are cosmopolitan microbial pathogens that cause fungous diseases in a wide range of insects via spore infection. Due to their natural enemy status, they have tremendous potential for use as microbial control agents against insect pests, especially subterranean pests for which few management options are available. The clover...

Evaluation of Pacific Lamprey Entosphenus Tridentatus Anatomical Structures as Records of Age and Isotope Histories

Creator:: Pelekai, Keala N.
Abstract:: The anadromous Pacific Lamprey (Entosphenus tridentatus) is a biologically and culturally important species native to the North Pacific Ocean and its adjacent freshwater tributaries. Pacific Lamprey have experienced declines in abundance and distribution throughout their native range, highlighting a need for further research on the species to better inform conservation...

The efficacy and costs of plasma transfusion in naturally diseased horses

Creator:: Busby, Madeleine F.
Abstract:: Hypoproteinemia secondary to gastrointestinal disease in horses has traditionally been treated with the administration of colloids such as equine plasma or hetastarch. While plasma transfusion is common, evidence-based guidelines for its use in hypoproteinemic horses are lacking. This study involved prospective and retrospective components that aimed to weigh the efficacy...

Identification, Quantification, and Risk Assessment of Polycyclic Aromatic Hydrocarbons and their Derivatives in Soil after Steam Enhanced Extraction

Creator:: Santiago Delgado, Lisandra
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are environmental contaminants produced mainly from the incomplete combustion and pyrolysis of organic matter. PAHs are among the major contaminants at over 800 Superfund sites, nationwide. Thermal remediation is used as a method to remediate soils contaminated with PAHs through the use of heat to mobilize...

Investigation of Nematocyst Discharge in Parasitic Cnidarians (Myxozoa)

Creator:: Americus, Benjamin E.
Abstract:: Myxozoans are an enigmatic group of obligately parasitic, microscopic cnidarians. They diverged from their free-living relatives over 600 million years ago and have highly reduced genomes. However, they have retained nematocyst stinging cells which characterize the phylum Cnidaria. Free-living cnidarians utilize this cellular weaponry for defense and predation whereas the...
