A comparison of the behavior and survival of juvenile coho salmon (Oncorhynchus kisutch) and steelhead trout (O. mykiss) in a small estuary system

Creator:: Clements, Shaun, Stahl, Thomas, and Schreck, Carl B.
Abstract:: We used radio and acoustic telemetry to study the behavior and survival of wild steelhead trout (Oncorhynchus mykiss) and hatchery coho salmon (Oncorhynchus kisutch) and steelhead outmigrants in a small coastal estuary during two years. Survival was generally low for hatchery fish but more variable, both within and between years,...

Climate change and the institutional resilience of international river basins

Creator:: De Stefano, Lucia, Duncan, James, Dinar, Shlomi, Stahl, Kerstin, Strzepek, Kenneth M., and Wolf, Aaron T.
Abstract:: In the existing 276 international river basins, the increase in water variability projected by most climate change scenarios may present serious challenges to riparian states.This research maps the institutional resilience to water variability in transboundary basins and combines it with both historic and projected variability regimes, with the objective of...

Characterizing the Accuracy of Phylogenetic Analyses that Leverage 16S rRNA Sequencing Data

Creator:: Humphreys, Ian R.
Abstract:: Investigations of 16S rRNA gene sequences hallmark modern microbiology. These sequences provide culture-independent insight into the abundance and distribution of microbiota and serve as a principle resource through which microbial community diversity is measured. Consequently, researchers rely on 16S gene sequences to test hypotheses rooted in ecology, evolution, and disease....

Genetic dissection of Victoria blight disease susceptibility in Arabidopsis thaliana

Creator:: Sweat, Teresa A.
Abstract:: The fungus Cochliobolus victoriae causes Victoria blight of oats and Arabidopsis and is pathogenic due to its production of a compound called victorin, which induces programmed cell death in sensitive plants. Victorin sensitivity in Arabidopsis is conferred by the dominant gene LOCUS ORCHESTRATING VICTORIN EFFECTS1 (LOV1), which encodes a coiled-coil-nucleotide...

Patterns of tree establishment and vegetation composition in relation to climate and topography of a subalpine meadow landscape, Jefferson Park, Oregon, USA

Creator:: Zald, Harold S. J.
Abstract:: The forest alpine tundra ecotone (FTE, also known as alpine treeline or subalpine parkland), is a conspicuous feature of mountain landscapes throughout the world. Climate change-driven increases in temperature are believed to result in FTE movement and tree invasion of subalpine meadows, which have been documented throughout the Northern Hemisphere...

An introduction to the analysis of shotgun metagenomic data

Creator:: Sharpton, Thomas J.
Abstract:: Environmental DNA sequencing has revealed the expansive biodiversity of microorganisms and clarified the relationship between host-associated microbial communities and host phenotype. Shotgun metagenomic DNA sequencing is a relatively new and powerful environmental sequencing approach that provides insight into community biodiversity and function. But, the analysis of metagenomic sequences is complicated...

Grazing Effects on Fuels and Plant Community Characteristics across Three Community Types in Wyoming Big Sagebrush Steppe

Creator:: Thomas, Tyler W.
Abstract:: Livestock grazing is the prominent land use in Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis [Beetle & A. Young] S.L. Welsh) steppe and has been present since the late 1800’s. There have been calls to remove livestock grazing from rangelands as historic grazing practices resulted in the degradation of some...

Investigation of hop downy mildew through association mapping and observations of the oospore

Creator:: Parker, Thomas B.
Abstract:: Hop downy mildew is a devastating disease affecting hop requiring expensive fungicide applications throughout the growing season. Plant resistance is highly desirable and theorized as being decidedly quantitative with dominance and epistasis involved in resistance. An association mapping approach using a mixed-model was used to identify AFLP markers associated with...

Natal source contributions of Pacific cod (Gadus macrocephalus) recruits in the southeastern Bering Sea

Creator:: DiMaria, Ruth A.
Abstract:: Effective and sustainable fisheries management not only depends on identifying and defining stocks (fundamental unit of management), but also on having knowledge of factors influencing the abundance, distribution and connectivity of stocks. Population structure of Pacific cod (Gadus macrocephalus) in the southeastern Bering Sea (EBS) remains unresolved although genetic data...

Implementation of a gross anatomical maturity key for the study of spawning phenology and geography of Pacific cod (Gadus macrocephalus)

Creator:: Neidetcher, Sandra
Abstract:: Pacific cod (Gadus macrocephalus) is an important species, both economically and ecologically in the Bering Sea and Aleutian Islands (BSAI). However, little is known about its spawning dynamics. To address this knowledge gap, I developed a gross anatomical maturity key for Pacific cod to assess temporal and spatial patterns of...
