Comparison of the water relations characteristics of woody plants in western Oregon

Creator:: Davis, Kent J.
Abstract:: I studied the water relations traits, twig conductivity, C'3 isotopic composition, and wood density of three conifer and five angiosperm species in western Oregon. This study took place from spring 2002 to fall 2003 on four sites. Species were selected to represent the diversity of drought tolerance of woody plants...

Assessing the Potential for a Late Pleistocene-Early Holocene Occupation at the Tahkenitch Landing Site (35DO130), Siuslaw National Forest, Oregon Dunes National Recreation Area

Creator:: Kirkpatrick, Molly C.
Abstract:: The archaeological record of the First Americans is known almost exclusively from interior sites located away from coastal margins. While archaeologists hypothesize that early peoples initially migrated into the Americas along the Pacific coast, environmental changes associated with postglacial sea level rise may have destroyed or obscured such early sites....

Searching for Late Pleistocene and Early Holocene-age Deposits in the Paleo-Tahkenitch Stream Basin: A Geoarchaeological Investigation in Douglas County, Oregon

Creator:: Newell, Zachary A.
Abstract:: Coastal stream basins are of great importance to efforts aimed at refining our understanding of the earliest populations that inhabited the ancient Oregon coast. However, geomorphic responses to post-glacial sea level rise in these settings has produced depositional environments that destroy or deeply bury late Pleistocene and early Holocene-age archaeological...

Early Oligocene intrusions in the central Coast Range of Oregon : petrography, geochemistry, geochronology and implications for the Tertiary magmatic evolution of the Cascadia forearc

Creator:: Oxford, Jeremiah
Abstract:: The Early Oligocene Oregon Coast Range Intrusions (OCRI) consist of gabbroic rocks and lesser alkalic intrusive bodies that were emplaced in marine sedimentary units and volcanic sequences within a Tertiary Cascadia forearc basin. The alkalic intrusions include nepheline syenite, camptonite, and alkaline basalt. The gabbros occur as dikes and differentiated...

Impacts of multispecies parasitism on coho salmon (Oncorhynchus kisutch) in Oregon

Creator:: Ferguson, Jayde A.
Abstract:: Diseases caused by parasites are recognized as significant sources of mortality in wild fish populations. I assessed the impacts of multispecies parasitism on a threatened stock of juvenile coho salmon (Oncorhynchus kisutch). A crucial prerequisite to this research was proper identification of parasites, which can be difficult for species lacking...

Analysis of semi-volatile trace metals in basaltic glass by LA-ICP-MS

Creator:: Loewen, Matthew W.
Abstract:: Semi-volatile trace metals (e.g., Cd, Sn, Pb, Zn, Cu, Mo) have been analyzed by using laser ablation ICP-MS in a number of silicate glasses (GSE-1G, GSD-1G, NIST 610, NIST 612, BCR-2G, BHVO-2G). Our work investigates and highlights sources of uncertainty in the analysis of semi-volatile metals using LA-ICP-MS. We identify...

Development and disease of opakapaka (Pristiopomoides filamentosus) larvae in culture

Creator:: Keafer, Briana
Abstract:: Opakapaka (Pristipomoides filamentosus) is a snapper (family Lutjanidae) native to the waters around Hawaii. Recent population declines of this commercially important species have increased interest in the culture of this fish. Survival of this fish through the larval period in culture has been consistently low, usually not exceeding 2%. The...

Exploring Volcano-Tectonic Connections in Cascadia – Temporal Linkages between Tephra Deposition and Megathrust Earthquakes

Creator:: Gutierrez, Joel C.
Abstract:: Explosively erupting volcanoes and megathrust earthquakes (Mw 8+ magnitude) occur at subduction zones and adjacent volcanic arcs. Volcanic eruptions are observed occurring close in time to megathrust earthquakes in the historical record from at least the 18th century CE to present in locations globally, including Japan in 1707 CE (Chesley...

Mapping Minerals, Charting Community: A Petrographic Study of Dalma Ware in the Chalcolithic Near East

Creator:: Buehlman-Barbeau, Savanna S.
Abstract:: The recent recovery of Dalma Ware at the archaeological site of Surezha, Northern Mesopotamia (modern-day Iraqi-Kurdistan), has raised questions regarding the method of its arrival in the region (Stein 2017; Stein & Fisher 2018). In order to assess Dalma Ware’s potential modes of dispersal into Northern Mesopotamia, ceramic petrography and...

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...
