White-breasted nuthatch density and nesting ecology in oak woodlands of the Willamette Valley, Oregon

Creator:: Viste-Sparkman, Karen
Abstract:: Habitat loss causes a reduction in available resources for wildlife, alters the configuration of remaining habitat, and may isolate wildlife populations. White-breasted nuthatches (Sitta carolinensis) are experiencing long-term population declines in the Willamette Valley of Oregon, where they are historically associated with oak woodlands. As secondary cavity-nesters, white-breasted nuthatches may...

Hydrogeologic field investigation and groundwater flow model of the southern Willamette Valley, Oregon

Creator:: Craner, Jeremy D.
Abstract:: Elevated groundwater nitrate (NO3 -) concentrations in the Southern Willamette Valley (SWV) caused the Oregon Department of Environmental Quality (ODEQ) to declare a Groundwater Management Area (GWMA) in Spring, 2004. To better understand direction of groundwater flow, groundwater age, and nitrate transport pathways of the SWV we developed a steady-state...

Mapping a path to sustainable utilization of bay clam resources in Oregon’s 21st century estuaries : an investigation into the potential of Oregon’s commercial bay clam fishery : Report to the Oregon Department of Fish and Wildlife and the Oregon Commercial Bay Clam Industry

Creator:: Endreny, Polly A. and Sylvia, Gil
Abstract:: This study was commissioned and funded by the Coastal Oregon Marine Experiment Station (COMES) to 1) identify the scientific and management issues constraining the advancement of the Oregon bay clam commercial industry, 2) explore scientific, management, and economic opportunities for the enhancement of the fishery, 3) outline and suggest mechanisms...

Public acceptance of disturbance-based forest management : a study of the attentive public in the Central Cascades Adaptive Management Area

Creator:: Mallon, Angela L.
Abstract:: Growing emphasis on ecosystem and landscape-level forest management across North America has spurred an examination of alternative management strategies which focus on emulating dynamic natural disturbance processes, particularly those associated with forest fire regimes. This topic is the cornerstone of research in the Blue River Landscape Study (BRLS) taking place...

Temporal and spatial variability of groundwater nitrate in the southern Willamette Valley of Oregon

Creator:: Mutti, Jeffrey Glenn
Abstract:: Groundwater nitrate contamination is a well-documented issue in the Southern Willamette Valley (SWV) of Oregon, as a Groundwater Management Area (GWMA) has recently been declared. As a GWMA, groundwater nitrate monitoring must occur until regional concentrations are below 7 mg/L NO3-N. However, the presence of temporal variability can make it...

Interpreting a weird and scenic landscape to park visitors : tectonic and volcanic processes of Craters of the Moon National Monument and Preserve, Idaho

Creator:: Truitt, Kimberly E.
Abstract:: This thesis develops a geology training manual for the Interpretation staff of Craters of the Moon National Monument and Preserve (CRMO) in southern Idaho. The manual will help the staff convey geologic principles to park visitors who are experiencing a landscape formed by volcanic processes. Basic geology and the most...

Phylogeography and population structure of least terns (Sterna antillarum)

Creator:: Draheim, Hope M.
Abstract:: Historically, least terns (Sterna antillarum) were one of the most common tern species in North America. However, population declines have resulted from direct and indirect anthropogenic pressures on their breeding and foraging habitat. Three subspecies of least terns have been described within the United States: California least tern (S. a....

The effect of landscape topography and in-stream habitat on the distribution, growth, and survival of Lahontan cutthroat trout (Oncorhynchus clarki henshawi) in a high desert watershed

Creator:: Boxall, George D.
Abstract:: Lahontan cutthroat trout (LCT) (Oncorhynchus clarki henshawi) are currently limited in their distribution to a patchwork of small isolated populations, the result of habitat degradation and natural variation in landscape and in-stream conditions. The objectives of this study were to determine how landscape level topographic features influence LCT distribution patterns....

Measurement and modeling the physical controls of snowmelt in the Pacific Northwest

Creator:: Mazurkiewicz, Adam B.
Abstract:: The physical controls of snowmelt in the Pacific Northwest (PNW) are poorly understood. While there have been numerous field and modeling investigations at the plot and watershed scale, few studies have identified how the snow energy balance (EB) components vary in importance both spatially and temporally. The identification of how...

Spatial and age class analysis of managed western juniper (Juniperus occidentalis) woodlands in central Oregon

Creator:: Zophy, Kelley T.
Abstract:: Juniper is a native species to Oregon and confers ecological benefits to wildlife when it is at savannah and transitional densities. Its range and extent have fluctuated with climatic change, but the current range expansion is unprecedented in its extent. The range expansion has been associated with the degradation of...
