Defining Biodiversity: A Local Assessment Of The Tahuayo River, Peru Using Self-Directed Photography, Rozsika D. Steele

All Master's Theses

The Área de Conservación Regional Comunal Tamshiyacu Tahuayo (ACRCTT), located in Loreto, Peru, protects 420,000 hectares of the Amazon basin. In 2009, the ACRCTT received formal government recognition after three decades of advocacy and conservation work by resident communities. Local resource users who live a subsistence lifestyle possess sophisticated Traditional Ecological Knowledge (TEK) that can be used to identify which constituents of biodiversity are culturally relevant. This information can help resource managers develop an operational definition of biodiversity. Self-directed photography is a research method that allows participants the opportunity to direct data collection and empowers them to visually communicate their …

Land Use Variation On Mid-Columbia Plateau Upland And Lowland Archaeology Sites, Cathy J. Anderson

All Master's Theses

Investigators of the Mid-Plateau archaeological record have interpreted artifact deposits in their environmental settings as evidence of human land use labeled as site types. Land use models consisting of cultural and environmental variables were developed from those studies. Those variables were compared to a sample of archaeological records located in the upland eastSaddleMountainsand lowland Wenas Creek-Yakima River confluence. While much of the archaeological record fits expectations derived from cultural-environmental models of human land use developed during this research thesis, significant variation in the archaeological record remains unexplained.

Mapping And Radiocarbon Dating Archaic Period Monuments: La Alberca Structure Complex, Highland Michoacán, Mexico, Mark F. Steinkraus

All Master's Theses

Ongoing collaborations with the Comunidad Indígena de Nuevo San Juan Parangaricutiro hold great potential for exploring the origins of sedentary ranked communities that predate others in Mesoamerica by as much as one thousand years. Three carbon samples from the lower buried portions of the Central Structure at La Alberca Complex yield a date range of 7245-6470 cal B.P. The carbon sample laying on an upper tier of the feature yields a date of 4780 cal B.P. These dates suggest that the feature is 7000 to 6000 years old and may have been in use as recently as 5000 to 4000 …

Sustainable Safari Practices: Proximity To Wildlife, Educational Intervention And The Quality Of Experience, Ryan Devine Tarver

All Master's Theses

This research examines the perceived quality of experience for safari tourists in relation to wildlife viewing proximities and the potential of educational interventions as a management strategy to mitigate adverse impacts of safari participant crowding. Crowding emanates from the safari tourist preferences to obtain close proximity to animals, particularly large mammals. Recognizing these preferences and associated impacts to animal behavior defined in previous research, we develop and deliver a survey instrument designed to measure the perceived quality of experience of the safari tourist while controlling for the viewing proximity variable. The survey instrument involves responding to stock photos selected to …

Everyday Farm Life In The Moxee Valley 1915-1950: Historical Ethnography, Terri Towner

All Master's Theses

This study collected oral histories of those who lived or worked in the Moxee Valley, within the greater Yakima Valley of Washington State from 1915-1950. It documents and records the historical and cultural processes of farm life and its evolution for people living in this foremost hop-growing region of the United States. The larger goal is to characterize the community and social processes for use as primary source documentation to create historically accurate programs at the Gendron Hop Ranch-Living History Farm near Moxee. Nineteen participants were interviewed. Topics addressed in the study include farming in the Valley, the household, roles …

Enriched Continental Flood Basalts From Depleted Mantle Melts: Modeling The Lithospheric Contamination Of Karoo Lavas From Antarctica, Jussi S. Heinonen, Arto V. Luttinen, Wendy A. Bohrson

All Faculty Scholarship for the College of the Sciences

Continental flood basalts (CFBs) represent large-scale melting events in the Earth’s upper mantle and show considerable geochemical heterogeneity that is typically linked to substantial contribution from underlying continental lithosphere. Large-scale partial melting of the cold subcontinental lithospheric mantle and the large amounts of crustal contamination suggested by traditional binary mixing or assimilation-fractional crystallization models are difficult to reconcile with the thermal and compositional characteristics of continental lithosphere, however. The well-exposed CFBs of Vestfjella, western Dronning Maud Land, Antarctica, belong to the Jurassic Karoo large igneous province and provide a prime locality to quantify mass contributions of lithospheric and sublithospheric sources …

Dramatic Loss Of Glacier Accumulation Area On The Tibetan Plateau Revealed By Ice Core Tritium And Mercury Records, S. Kang, F. Wang, U. Morgenstern, Y. Zhang, B. Grigholm, Susan D. Kaspari, M. Schwikowski, J. Ren, T. Yao, D. Qin, P. A. Mayewski

All Faculty Scholarship for the College of the Sciences

Two ice cores were retrieved from high elevations (~5800 m a.s.l.) at Mt. Nyainqêntanglha and Mt. Geladaindong in the southern and central Tibetan Plateau region. The combined tracer analysis of tritium (³H), ²¹⁰Pb and mercury, along with other chemical records, provided multiple lines of evidence supporting that the two coring sites had not received net ice accumulation since at least the 1950s and 1980s, respectively. These results implied an annual ice loss rate of more than several hundred millimeter water equivalent over the past 30–60 years. Both mass balance modeling at the sites and in situ data …

Using Satellite Image Analysis For Locating Prehistoric Archaeological Sites In Alaska's Central Brooks Range, Robert Hickey, J. Keeney

Geography Faculty Scholarship

In this pilot study, we apply satellite image analysis to archaeological site prospection in Alaska's Brooks Range. Our goal was to test whether satellite remote sensing, which has been successful in locating large archaeological features associated with sedentary peoples, could be applied to arctic interior sites associated with mobile hunter–gatherers. In particular, we strove to develop a relatively straightforward and inexpensive model using existing data which could be used to help guide archaeology surveys. Using 1-m resolution IKONOS imagery of Lake Matcharak along the upper Noatak River, we produced a Normalized Difference Vegetation Index (NDVI) and tasseled cap transformation of …

Eastern Washington Wildfires: Tracking Land Recovery In The Colockum Tarps Wildfire Area, Michael Balda, Allison Shinn

Symposium Of University Research and Creative Expression (SOURCE)

Eastern Washington State has seen an increase in wildfire activity because of policies of fire suppression and changing climate. The Colockum Tarps wildfire started on July 27, 2013, in Malaga, Washington, due to a water pump malfunction. After ignition, the fire quickly moved south-southwest and burned a total area of 80,408 acres of grasslands and forest. We combined fieldwork and geospatial analysis of aerial photography and satellite imagery to examine vegetative recovery within the fire area. Using ArcGIS and PCI Geomatica, we analyzed 2013 National Agricultural Imaging Program (NAIP) images and a wildfire perimeter shapefile from the Bureau of Land …

Insect Communities: Ellensburg Upstream Versus Downstream Sites, Michael Balda

Symposium Of University Research and Creative Expression (SOURCE)

Urban stream syndrome occurs when an urban area affects a stream system. Stream burial is common in urban systems, and burial blocks incoming light, potentially affecting available food resources and, in turn, affecting the insect communities. I tested for changes to the stream ecosystem as a result of urbanization by measuring insect community parameters upstream and downstream of buried sites in the three creeks in Ellensburg, Washington, that are affected by urban stream syndrome. I measured chlorophyll on rocks, total suspended sediments (TSS), fine benthic organic matter (FBOM), ammonium, and phosphorus to relate to insect communities characteristics. I hypothesized that …

Mountain Passes And Saddle Points, James Bisgard

All Faculty Scholarship for the College of the Sciences

Variational methods find solutions of equations by considering a solution as a critical point of an appropriately chosen function. Local minima and maxima are well-known types of critical points. We explore methods for finding critical points that are neither local maxima or minima, but instead are mountain passes or saddle points. Criteria for the existence of minima or maxima are well known, but those for mountain passes or saddle points are less well known. We give an accessible treatment of some criteria for the existence of such points (including the mountain pass lemma), as well as describe a method that …

Analysis Of Spatial Variability Of Near-Surface Soil Moisture To Increase Rainfall-Runoff Modelling Accuracy In Sw Hungary, P. Hegedüs, S. Czigány, E. Pirkhoffer, L. Balatonyi, Robert Hickey

All Faculty Scholarship for the College of the Sciences

Between September 5, 2008 and September 5, 2009, near-surface soil moisture time series were collected in the northern part of a 1.7 km2 watershed in SWHungary at 14 monitoring locations using a portable TDR-300 soil moisture sensor. The objectives of this study are to increase the accuracy of soil moisture measurement at watershed scale, to improve flood forecasting accuracy, and to optimize soil moisture sensor density.

According to our results, in 10 of 13 cases, a strong correlation exists between the measured soil moisture data of Station 5 and all other monitoring stations; Station 5 is considered representative for the …

Twentieth Century Dust Lows And The Weakening Of The Westerly Winds Over The Tibetan Plateau, Bjorn Grigholm, P. A. Mayewski, S. Kang, Y. Zhang, U. Morgenstern, M. Schwikowski, Susan D. Kaspari, V. Aizen, E. Aizen, N. Takeuchi, K. A. Maasch, S. Birkel, M. Handley, S. Sneed

Understanding past atmospheric dust variability is necessary to put modern atmospheric dust into historical context and assess the impacts of dust on the climate. In Asia, meteorological data of atmospheric dust is temporally limited, beginning only in the 1950s. High‐resolution ice cores provide the ideal archive for reconstructing preinstrumental atmospheric dust concentrations. Using a ~500 year (1477–1982 A.D.) annually resolved calcium (Ca) dust proxy from a Tibetan Plateau (TP) ice core, we demonstrate the lowest atmospheric dust concentrations in the past ~500 years during the latter twentieth century. Declines in late nineteenth to twentieth century Ca concentrations significantly correspond with …

Significance Evaluation Of The Forgotten Creek Site, Joy D. Ferry

All Master's Theses

Archaeological research has recognized the importance of montane environments in the subsistence and settlement strategies of pre-contact peoples. Yet little is understood about variation in the manner in which pre-contact peoples were using upland environments. In order to ascertain whether there is functional and/or technological variation between montane sites in comparable environmental settings, four lithic assemblages (45PI406, 45PI408, 45PI429, and 45PI438) from sites in the upper maritime forest and subalpine zone of Mount Rainier were compared. An evolutionary archaeology model was applied to define and measure variables relevant to stone tool manufacture and use. Statistically significant non-random associations were contextualized …
