Social calling behavior of Southeast Alaskan humpback whales (Megaptera novaeangliae) : classification and context

Creator:: Fournet, Michelle Elizabeth Hardy
Abstract:: Humpback whales (Megaptera novaeangliae) are vocal baleen whales that exhibit complex social interactions that vary spatially and seasonally. Across their range, humpback whales produce a wide array of vocalizations including ‘song’, foraging vocalizations, and a range of vocalizations known as social calls -- unclassified non-song vocalizations. This study investigates the...

Distributions and fishery associations of immature short-tailed albatrosses (Phoebastria albatrus) in the North Pacific

Creator:: O'Connor, Amelia J.
Abstract:: Short-tailed albatrosses (Phoebastria albatrus, hereafter "STAL") migrate throughout the North Pacific, overlapping with multiple large scale fisheries. In the Bering Sea, documented bycatch of this species is a focal conservation concern, due to the fact that this species is listed as "endangered" under the U.S. Endangered Species Act. We conducted...

Effects of land use policy on urban growth rates in the Willamette Valley, Oregon

Creator:: Davis, Ellen and Davis, Ellen H.
Abstract:: This study seeks to determine the correlation between changes in statewide land use planning policies and the resulting periods of high or low urban growth in the Willamette Valley, Oregon using automated classification methods and freely available satellite imagery. To protect its farms, forests and open spaces, Oregon became the...

Risky business : evaluating the vulnerability and impacts from simulated oil spills in the Gulf of Mexico

Creator:: Nelson, Jake R.
Abstract:: Exploration and production of oil in the Gulf of Mexico has seen an astonishing increase since the first well was drilled in 1936. Much of the current exploration is occurring in waters greater than 5000 feet. The largest and most unprecedented oil spill in the United States occurred on April...

A Bayesian approach to marine spatial planning

Creator:: Erhardt, Morgan William
Abstract:: The marine ecosystem provides a broad spectrum of services for a wide array of user groups. Such broad use of marine resources often results in use conflicts between ecosystem elements and human interests. To help mitigate these conflicts, the Bayesian Analysis for Spatial Siting (BASS) tool was developed to incorporate...

A GIS investigation of indigenous intensification of native food plants : humans as environmental variable in maxent habitat suitability modeling of Camassia in Oregon

Creator:: Elliott, Braden T.
Abstract:: This thesis merges the fields of Ecology and Anthropology by applying Habitat Suitability Modeling to the relationship between people and plants in the Pacific Northwest. In it, I create and optimize two Maxent habitat suitability models for camas (Camassia spp.) in Oregon. The first model describes the physical environment of...

Range-use estimation and encounter probability for juvenile Steller sea lions (Eumetopias jubatus) in the Prince William Sound-Kenai Fjords region of Alaska

Creator:: Meck, Stephen R.
Abstract:: Range, areas of concentrated activity, and dispersal characteristics for juvenile Steller sea lions Eumetopias jubatus in the endangered western population (west of 144° W in the Gulf of Alaska) are poorly understood. This study quantified space use by analyzing post-release telemetric tracking data from satellite transmitters externally attached to n...

Spatial and temporal effects of atmospheric deposition, climate, and land management on forest nutrient cycling and biodiversity

Creator:: McDonnell, Todd C.
Abstract:: Emissions largely associated with the combustion of fossil fuels and agriculture has caused elevated atmospheric deposition of nitrogen (N) and sulfur (S) throughout much of the developed world. Increased atmospheric deposition of N and S can lead to soil and surface water acidification and affect forest soil nutrient supply. The...

Economic optimization of forest biomass processing and transport

Creator:: Zamora Cristales, René Arturo
Abstract:: An economic analysis and optimization of forest biomass processing and transportation at the operational level is presented. Renewable sources of energy have captured the interest of public and private institutions to develop cost-effective supply chains to reduce dependence on fossil fuels. The production of energy from forest harvest residues constitutes...

Spatial distribution and the probability of occurrence of beluga whales (Delphinapterus leucas) in Alaskan Arctic

Creator:: Romeo, Lucy F.
Abstract:: The known distribution of beluga whales ranges from sub-Arctic to Arctic waters where they migrate in pods in response to environmental factors such as the presence of sea ice and prey. This study uses bivariate and multivariate analysis techniques to measure how environmental covariates are associated with the spatial-temporal distribution...
