Eastern Gray Squirrel Ecology and Interactions with Western Gray Squirrels
(2013-07-23)Populations of State-threatened western gray squirrels (<italic>Sciurus griseus</italic>) have declined in areas invaded by introduced eastern gray squirrels (<italic>S. carolinensis</italic>) in the Western United States, ... -
Ecological constraints of antibiotic resistant gram-negative coliforms in an urban riverine ecosystem
The distribution of antibiotic resistant bacteria in surface water is largely unknown but nowhere is this information more critical to understanding ecosystem function and protecting public health than in urban streams. ... -
Ecological interactions between Euphydryas editha larvae and their host plants
I examined ecological interactions between larvae of Euphydryas editha (Lepidoptera: Nymphalidae) and their host plants. These caterpillars, and the plants they eat, provide an intriguing system for studying several aspects ... -
Ecologists and Organizers: Participatory Research for Shared Understanding in the Green Seattle Partnership
(2012-09-13)The city of Seattle's landscape of urban natural areas provides a myriad of social and ecological services, but many of Seattle's forested parks are experiencing a serious decline in biodiversity and ecosystem function due ... -
Ecology and Conservation of the Western Gray Squirrel (Sciurus griseus) in the North Cascades
(2012-09-13)University of Washington Abstract Ecology and Conservation of the Western Gray Squirrel in the North Cascades Kathryn Diane Stuart Chair of the Supervisory Committee: Associate Director and Professor Stephen D. West School ... -
An Econometric Analysis of Paid Sewer Backup Damage Claims in Seattle
(2013-07-25)University of Washington Abstract An Econometric Analysis of Paid Sewer Backup Damage Claims in Seattle Joshua Simpson Chair of the Supervisory Committee: Assistant Professor Sergey Rabotyagov School of Environment and ... -
Ecophysiology as a tool for evaluating invasive-plant based bioenergies: physiological and ecological case-studies of Arundo donax and Elaeagnus angustifolia
(2013-02-25)In recent years, environmental and social pressures have fostered the development of biomass based energies. Development of `ideal' biomass feedstocks has led to characterizations of physiological traits that are similar ... -
The Effect of Agricultural Riparian Buffer Width on Generalist Natural Enemy Diversity
(2014-02-24)University of Washington Abstract The Effect of Agricultural Riparian Buffer Width on Generalist Natural Enemy Diversity Matthew Chabot Maria Chair of the Supervisory Committee: Professor Sarah E. Reichard School of ... -
Effect of Armillaria Root Disease on Stand Structure, Composition, and Potential Fire Behavior in a Managed Ponderosa Pine Forest near Glenwood, WA
(2012-09-13)Root disease and wildfire are important disturbance agents in western North American forests. It has been speculated that root disease increases potential fire behavior, since root disease kills trees and contributes to ... -
Effects of agricultural drainage ditch maintenance on water temperature in the Snoqualmie River valley, Washington State
(2013-07-25)Water temperature profoundly affects the health of freshwater ecosystems and is an increasing water quality concern in the Pacific Northwest, where warm stream temperatures can threaten the survival and growth of already ... -
Effects of artificial, stand-level induced drought and thinning on Pseudotsuga menziesii plantation eco-physiology, and soil respiration
Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) is an important tree species in the Pacific Northwest (PNW), ranging from central British Columbia to Mexico. Douglas-fir is widely used for wood production and silvicultural ... -
The Effects of Biogeoclimatic Properties on Water and Nitrogen Availability and Douglas-Fir Growth and Fertilizer Response in the Pacific Northwest
(2012-09-13)Coastal Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) is the predominant plantation species of the western Pacific Northwest, although soil and climate characteristics vary throughout the region. This study investigated ... -
Effects of Cooper's hawk predation and presence on songbird survivorship, nesting success, and community structure
(2012-09-13)The field of urban ecology seeks to incorporate humans into ecological studies, particularly within the built environment. This can include both the study of urban landscapes, as well as the study of ecology in urban ... -
Effects of dam removal on resident fish movement in Cijiawan River, Taiwan
(2012-09-13)Freshwater fish change their movement patterns in response to natural or anthropogenic changes in habitat. Dam removal, a major restoration practice to restore river longitudinal connectivity, can affect river habitat with ... -
The effects of forest management intensity on carbon storage and revenue in Western Washington: A model and Monte Carlo-based case study of tradeoffs at Pack Forest
(2013-07-23)Forest C offsets allow payments to forest owners who improve carbon (C) uptake and storage. I quantified the amount and value of C under different intensities of management practices at Pack Forest in the western Cascade ... -
Effects of forest management, prey, and predators on the habitat selection of fishers in the South Cascades of Washington.
One of the most common reasons for failure of wildlife reintroductions is releasing animals into low quality habitat that does not meet resource needs. Food availability and the presence of potential predators or competitors ... -
Effects of High-Severity Wildfires on the Ectomycorrhizal Fungal Community of Ponderosa Pine Ecosystems in Eastern Washington
Ectomycorrhizal (EcM) fungi have the ability to mediate ecosystem responses to post-fire environmental changes, yet we have limited understanding of how high-severity wildfires influence the EcM community, especially in ... -
Effects of local vegetation and landscape patterns on avian biodiversity in the threatened oak habitat of the Willamette Valley, Oregon
(2013-02-25)Both fine scale patterns of vegetation and coarser scale landscape patterns affect bird community composition and structure. However, the relative importance of the drivers at these two spatial scales continues to be ... -
Effects of low-severity fire on species composition and structure in montane forests of the Sierra Nevada, California, USA
Climate, topography, and fire influence the species composition and structure of montane forest communities in the Sierra Nevada. This thesis uses data from 97, 0.1 ha plots (46 unburned since 1930; 51 burned at moderate-severity ...
