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...

Partial purification and determination of some properties of an aminotransferase of pea (Pisum sativum L.) plants

Creator:: Matheron, Michael Earl
Abstract:: A transaminase (aminotransferase, EC 2. 6. 1) was extracted and purified approximately 148-fold from shoot tips of pea (Pisum sativum L. cv. Alaska) seedlings and some properties of the enzyme were determined. The purification included acetone precipitation followed by column chromatography on hydroxylapatite. With a-ketoglutarate as co-substrate, the acetone precipitated...

Physiology of senescence of the shoot apex in Pisum sativum L.

Creator:: Ecklund, Paul Richard, 1941-
Abstract:: Shoot apex senescence is defined as the collective progressive and deteriorative processes which ultimately terminate the functional life of the shoot apex. Senescence of shoot apices of Pisum sativum L. 'Alaska' as measured by cessation of stem elongation was delayed by removal of flowers and by treatment with gibberellin A₃...

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 evaluation of well-water nitrate exposure and related health risks in the Lower Umatilla Basin of Oregon

Creator:: Mitchell, Thomas J.
Abstract:: Excessive nitrates in drinking water pose a human health threat, especially to infants. Methemoglobinemia, or blue-baby syndrome, is a potentially fatal condition that inhibits the ability of red blood cells to bind and transport oxygen. Nitrates/nitrites have also been linked to such conditions as cancer, birth defects, and behavioral and...

Universal computing systems. Part 1, Simulation of any Normal Algorithm by Turing machine. Part 2, A universal Turing machine to translate any Turing machine to a Normal Algorithm

Creator:: Nelson, Thomas Clayton
Abstract:: In this paper a direct, constructive proof of the equivalence of the Normal Algorithm and Turing machine using the Turing machines NAS (Normal Algorithm Simulator) and NAC (Normal Algorithm Converter) is presented. The Turing machine NAS can simulate any particular Normal Algorithm, and NAG can convert the quintuples of a...
