Free-choice family learning in a bilingual marine science program : a qualitative investigation of interactions and long-term impacts among Mexican-descent families

Creator:: Schmoock, Heidi I.
Abstract:: In the past most research of family learning in informal science learning environments has included limited diversity among participants considering ethnic, cultural, and social economic status. The diversity seen in informal learning environments such as museums does not typically reflect that of the general population. Therefore, in order to foster...

The influence of pollinators on the maintenance of mixed mating in a population of the blue columbine, Aquilegia coerulea (Ranunculaceae)

Creator:: Sweet, Heather R.
Abstract:: Pollination ecology may play an important role in the maintenance of selfing in populations of self-compatible hermaphroditic plants where both selfing and outcrossing occur (mixed mating). Behavior and abundance of pollinators can influence the two major modes of selfing; autogamy (selfing within a flower) and geitonogamy (selfing between flowers on...

Phylogenetics and genomic patterns of speciation in Pinus with an empahsis on subgenus Strobus

Creator:: Syring, John V.
Abstract:: Data from nuclear ribosomal internal transcribed spacer regions (nrITS) and chloroplast DNA (cpDNA) have failed to resolve phylogenetic relationships in Pinus. To provide greater interspecific resolution, five low-copy nuclear genes were developed from mapped conifer anchor loci. Four genes were sequenced from species representing all Pinus subsections. Individual loci do...

New perspectives on evolutionary relationships within Pinus (Pinaceae) and within subsection Ponderosae (subgenus Pinus)

Creator:: Willyard, Ann Nachreiner
Abstract:: A fossil-calibrated phylogenetic framework based on exemplars from each of the four taxonomic sections within Pinus was created using multiple nuclear and chloroplast loci. Calibration at the well-defined subgeneric split within Pinus with either fossil leaves and cones (ca. 45 million years ago) or fossil wood (ca. 85 million years...

Biology and management of the potato tuberworm in the Pacific Northwest

Creator:: Oregon State University. Extension Service, Washington State University. Extension, University of Idaho. Extension, Rondon, Silvia I., DeBano, Sandra J., Clough, George H., 1945-, Dogramaci, Mahmut, Schreiber, Alan, Jensen, Andrew, Alvarez, Juan M., Thornton, Michael, Barbour, James, and Pacific Northwest Cooperative Extension
Abstract:: The potato tuberworm, Phthorimaea operculella, is a pest of many solanaceous crops, including potatoes. Commonly found in tropical and subtropical regions throughout the world, potato tuberworm (PTW) is one of the most important constraints to potato production worldwide. Larvae of this species mine leaves, stems, and petioles and excavate tunnels...

Active site studies and design of ligands for affinity column separation of 2,5-dihydroxyacetanilide epoxidase (DHAE) I and II

Creator:: Allen, Scott E.
Abstract:: A series of compounds, 7-8 and 20-25, were tested as competitive inhibitors of 2,5-dihydroxyacetanilide epoxidase I (DHAE I) and DHAE II. A Hammett plot was constructed for each enzyme to determine the effect of electron density on inhibition. DHAE I gave a linear, highly correlated plot (r²=0.91) that signifies the...

Biochemical, molecular and physiological characterization of 1-butanol dehydrogenases of Pseudomonas butanovora in butane and 1-butanol metabolism

Creator:: Vangnai, Alisa S.
Abstract:: Butane-grown Pseudomonas butanovora oxidized butane by a soluble butane monooxygenase through the terminal pathway yielding 1 -butanol as the predominant product. Alcohol dehydrogenases (ADHs) involved in butane oxidation in P. butanovora were purified and characterized at the biochemical, genetic and physiological levels. Butane-grown P. butanovora expressed a type I soluble...

Remote sensing for monitoring regional carbon dynamics associated with land cover and land use change along the Mesoamerican Biological Corridor

Creator:: Hayes, Daniel J., 1974-
Abstract:: Human activities are causing profound changes to the global environment, yet the potential consequences of these changes on rising atmospheric carbon dioxide and climate change are not well understood. Improving our understanding of these processes requires an enhanced awareness of how global ecosystems are changing and how these changes affect...

Part I: Synthetic studies toward the southern portion of Azaspiracid-1; Part II: Total synthesis of amphidinolide B₁ and the proposed structure of amphidinolide B₂

Creator:: Lu, Liang
Abstract:: The structural architecture present in marine toxin azaspiracid - 20 stereocenters, 9 rings, 3 separated spirocenters - has attracted considerable synthetic attention. Our efforts toward the synthesis of azaspiracid have led to the completion of both C₁-C₂₆ northern and C₂₇-C₄₀ southern halves. Herein, the synthesis of southern FGHI ring system...

Abstract:: In the North Atlantic, cold, relatively salty water sinks in the icy Labrador and Greenland seas, forming North Atlantic Deep Water (NADW). This circulates through the global ocean, driving ocean overturning and global heat transport and, thus, impacting global climate. As one of the most climatically sensitive regions on Earth,...
