Validating songbird habitat relationship models

Creator:: Wilson, Dorothy G.
Abstract:: Models are commonly used to assess and predict wildlife response to management practices. Model validation is essential if managers are to use them with confidence. Fifteen forest bird-habitat relationship models were developed by biologists using data collected from private forestland in southwest Washington. These models predict species' probability of occurring...

Twenty-year changes in riparian bird communities of east-central Oregon

Creator:: Ellis, Michael S.
Abstract:: Over the last 50 years, riparian zones in the semi-arid West have gained recognition as disproportionately important habitats for both breeding bird communities and agricultural operations. Despite growing interest in exploring avian-habitat relationships in these systems to better inform land management, few studies have attempted to describe temporal changes in...

Small mammal responses to silvicultural fuels treatments in southwest Oregon

Creator:: Manning, Jeffrey A.
Abstract:: Despite the belief that fuels management, a form of prescribed fire that reduces accumulated fuels in commercially thinned forests, is necessary to restore forest 'health' in the Pacific Northwest, its effects on wildlife has received little attention in the scientific literature. Because fuels management is supported, funded, and implemented nationwide...

Riparian vegetation and larval Pacific Giant (Dicamptodon tenebrosus) and adult Western Redback (Plethodon vehiculum) salamanders in the Oregon Coast Range

Creator:: Graff, Paula (Paula Hayes)
Abstract:: Riparian areas in the Pacific Northwest provide important biotic and abiotic features, such as down wood, moist microsites, and abundant invertebrate prey that benefit aquatic and terrestrial amphibians. Reported high densities of amphibians from streams and riparian areas in the Pacific Northwest highlight their importance in riparian food webs. Amphibians...

Range-wide abundance and fluctuating asymmetry patterns of sagebrush-obligate passerine birds

Creator:: Krissman, Cortnie M.
Abstract:: North American sagebrush (Artemisia spp.) ecosystems are suffering from reductions in habitat extent and quality. Only about 50% of sagebrush remains from pre-settlement conditions, and much of the remaining habitat is fragmented or degraded by invasive species, fire suppression and overgrazing. Sagebrush-obligate species are experiencing population declines as a result...

Over-winter demography of the gray-tailed vole (Microtus canicaudus) in fragmented and continuous habitats

Creator:: Brunkal, Heidi L.
Abstract:: Large scale disruption of natural habitats worldwide has led to concern over the effects of habitat fragmentation on wildlife populations. Small scale experiments may be a useful tool for discovering effects of fragmentation over larger landscape scales. I sought to explore the potential for using voles as an experimental model...

Integrative risk analysis of vector-borne disease

Creator:: Orme Zavaleta, Jennifer
Abstract:: In this dissertation I explore the application of two novel modeling techniques for improving risk analysis of vector-borne disease and discuss their potential use in integrating environmental risk assessment that guides environmental and public health decisions. Techniques for analyzing risk have been considered inadequate due to a lack of understanding...

Influence of vegetation structure and food habits on effects of guthion 2S® (Azinphos-methyl) on small mammals

Creator:: Schauber, Eric M.
Abstract:: The Quotient Method (QM), a laboratory-based risk assessment methodology used by the Environmental Protection Agency to evaluate pesticides for registration and use, has not been thoroughly field-tested and its performance has not always been reliable. My objective was to determine if variation in vegetation structure or diet of exposed animals...

Improving ecological risk assessment of pesticides for nontarget terrestrial vertebrates

Creator:: Wang, Guiming
Abstract:: The Quotient Method (QM) is used by the United States Environmental Protection Agency (USEPA) in ecological risk assessments of pesticides for nontarget organisms. The QM requires several assumptions regarding exposure and hazards of pesticides to wildlife; several of these assumptions have not been tested. During 1997-99, I conducted three experiments...
