Combining Disparate Data Sources with Ecosystem and Integrated Models: Case Studies for Improving Management of Protected Species

Creator:: Chasco, Brandon E.
Abstract:: Globally, the number of threatened species is increasing and conserving them is a high priority to the scientific community. Assessing the status of these protected species is challenging due to missing, contested, and or contradictory data streams. Integrated models (IMs) provide a statistical framework for combining disparate data sources to...

Long Term Trends and Sources of Sound in United States Waters

Creator:: Haver, Samara M.
Abstract:: Passive acoustic monitoring is a valuable tool for observing the status of marine environments. Comparisons of underwater soundscapes over temporal and spatial scales can provide data to inform marine conservation efforts, including protection of threatened and endangered species. This dissertation utilizes passive acoustic data collected via a broadly spaced array...

A mendelian study of Crassostrea gigas

Creator:: Smoker, Janet Van Dusen
Abstract:: The genotype frequencies of one-year-old oyster spat (Crassostrea gigas) from parents of known genotype, are compared to the frequencies expected with Mendelian inheritance. The genotypes are characterized at three enzyme loci, Aspartate amino-transferase (AAT), Phosphohexose isomerase (PHI) and Leucine aminopeptidase (LAP), and a general protein locus. In this study expression...

Using DNA Metabarcoding to Study Interactions Between Native Bees and Plants: Technical Developments and Applications

Creator:: Arstingstall, Katherine A.
Abstract:: Pollination is an essential ecosystem service that sustains functioning ecosystems and aids in food production. In response to recent, widespread declines of managed and native bee populations, many land managers have shown interest in developing conservation and restoration plans for enhancing native bee habitat. However, there is a lack of...

A genetic study of the red-band trout (Salmo sp.)

Creator:: Wilmot, Richard L.
Abstract:: A group of trout that reside in streams of the desiccating lake basins of southeastern Oregon differ markedly from other known Salmo. Known commonly as the red-band trout, this fish was subjected to chromosome analysis for comparison with other species of western North American Salmo. The karyotype of the red-banded...

Studies on the molluscan and fish hosts of the "salmon poisoning" fluke, Nanophyetus salmincola (Chapin)

Creator:: Gebhardt, Gary Alan.
Abstract:: This study¹ was undertaken: (1) to obtain information on the distribution of the snail, Oxytrema silicula, in three coastal rivers in Oregon, and the seasonal incidence of infection in these snails and in snails from an inland stream, with the cercariae of the trematode, Nanophyetus salinincola; (2) to follow cercarial...

Passive acoustic monitoring of owls: two studies in forested landscapes of the Pacific Northwest

Creator:: Duchac, Leila S.
Abstract:: Nearly all birds communicate through sound, and there has been much study of avian populations and communities using song and other vocalizations. Owls are no exception as they defend territories, advertise for mates, and defend against threats using various vocalizations. However, due to their generally nocturnal habits, some owl species...

A morphometric study of growth and condition in juvenile English sole (Pleuronectes vetulus) relative to environment

Creator:: Weber, Madeleine Demaries
Abstract:: This thesis focuses upon whether stressful aspects of an organism's environment are reflected by that organism's shape. It presents an application of the powerful thin-plate spline and relative warp methods from morphometric analysis to demonstrate the overall utility of morphometrics in detecting environmental stress in an estuarine flatfish, the English...

Using Oregon trawl logbooks to study spatial and temporal characteristics of commercial groundfish species associations

Creator:: Lee, Yong Woo
Abstract:: Species associations of fifteen major commercial groundfish species in the northeastern Pacific ocean and their spatial and temporal characteristics were studied using Oregon bottom trawl logbook data, 1987 to 1993. Screening procedures were used to remove questionable data from the original logbook files, which resulted in the exclusion of information...
