Geochemical characterization methods are commonly used in the reconstruction of prehistoric raw material use and procurement systems. Trace element studies of lithic source material and artifacts, specifically those made of obsidian, can reveal important information about the environmental and cultural factors which influence the prehistoric distribution of raw material. The...
Since the late 1970s, archaeology has grown into an industry whose
practitioners work in both public and private sectors. As an industry, modern
archeology is commonly known as Cultural Resources Management, or CRM. CRM
emerged from a surplus of employment opportunities made available to archeologists
after the passing of National...
The purpose of this research was to see if there were technological differences in ground stone manufacturing and use from a single site that had been occupied for over 600 years, A.D. 550-A.D. 1150, and had multiple occupations that evolved over time (Late Pithouse Phases, Georgetown, San Francisco, and Three...
The prehistory of Central Oregon is explored through the examination of six archaeological sites and two isolated finds from the Upper Deschutes River Basin. Inquiry focuses on the land use, mobility, technological organization, and raw material procurement of the aboriginal inhabitants of the area. Archaeological data presented here are augmented...
In the past, archaeological investigations have recovered material culture that have often been stored as museum property without a focused analysis or written report of the results. This study focuses on one such assemblage ofchipped stone projectile points from the Bachman Cave locality of southwestern Idaho that has been stored...
Bone Cave is located in the High Lava Plains of Central Oregon, just east of Bend. Excavations were conducted at the site to examine the extent of looter disturbance, and to address research questions focused on prehistoric settlement and subsistence. In the excavation of more than 10 m3 of sediment...
This thesis examines prehistoric land use patterns of the entire North Santiam subbasin, located on the western slopes of the Oregon Cascade Range. The objective of this analysis is three-fold: 1) to contribute to reconstructing the cultural chronology of the area; 2) to address the use of raw material by...
The Quartz Mountain Obsidian Quarry is located in the Southeast corner of the
Bend Fort Rock Ranger District in central Oregon, approximately forty-five miles
southeast of Bend, Oregon.
The research of the Quartz Mountain Obsidian Quarry began with a literature
search of other quarry sites in the area and the...
This project hypothesizes that the use of multiple ground-based remote sensing methods can collectively characterize the geophysical signatures of four marked human burials at the Confederated Tribes of Siletz Indians historic period cemetery. If the geophysical signatures of the marked burials can be characterized, these signatures may be used to...
Located on the central Oregon coast, the Umpqua Eden site (35D083) yielded an artifact assemblage which is one of the five largest assemblages from the Oregon coast. The first aspect of the site that I looked at is the people who lived at the site, the ancestors of the Confederated...
Prehistoric rock art has intrigued and fascinated researchers from around the world for nearly 300 years. Having once been embraced for its cultural and scientific
uniqueness, the study of prehistoric rock art showed promise in being able to open new
doors of understanding, above and beyond the written record. In...
The remodeling of the central nervous system (CNS) during metamorphosis in Drosophila melanogaster is a prime model system in which to study the genetic control of the sexual dimorphisms in the abdominal ganglion of the CNS. I have been using a P[tau-lacZ] enhancer trap line, 4.078, to label a segmentally...
The fruitless (fru) gene in Drosophila melanogaster is a multifunctional gene having sex-specific functions in the regulation of male sexual behavior and sex-nonspecific functions affecting adult viability and external morphology. While much attention has focused on fru's sex-specific roles, little is known about its sex-nonspecific functions. The embryonic central nervous...
Courtship and copulation behaviors in Drosophila melanogaster males are regulated by sex-specific products from the gene fruitless (fru). Male-specific FRU proteins (FRU[superscript M]) are putative transcription factors of the BTB-ZnF family that likely act by controlling development and maintenance of the neural circuitry used during male sexual behavior. However, which...
With human activity causing increases in turbidity in coastal marine waters, it is of economic and ecological importance to understand how this increase will affect organisms living in these areas. At most risk may be predators, such as many teleosts and cephalopods, reliant on vision to detect and capture prey....
CantonS wild-type flies were used to determine sex-specific differences in the daily
locomotor activity patterns in males and females. Under light entrainment, when flies are
kept in a 12:12 light-dark condition, both males and females showed bimodal activity
with a morning peak around lights-on and an evening peak around lights...
Soil respiration, or the combined CO₂ emissions from roots and soil microorganisms, constitutes one of the largest losses of carbon (C) from terrestrial ecosystems. The major drivers of soil respiration, which include soil moisture, temperature, and substrate quality, have been known for some time. Nevertheless,
correlations between these drivers and...
My objectives were to investigate the correlation of height and diameter growth in young Douglas-fir (Pseudotsuga menziesii) plantations with stand density, and to determine the effects of stand density on the canopy boundary layer conductance (g[subscript]ac) and microclimate characteristics of young Douglas-fir plantations. I measured annual height (h) and diameter...
Canopy structure has a significant impact on the canopy hydrology of
Douglas-fir forests in the Pacific Northwest (PNW). Whole canopy rainfall
interception was measured for young Douglas-fir forest and compared to an
old-growth Douglas-fir forest. The old-growth forest had significantly greater
canopy water storage capacity (5) and direct throughfall fraction...
