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...

Using GIS to illustrate the geospatial and socio-ecological intersection between climate change, energy production, and sustainable fisheries management in Oregon

Creator:: Cohn, Leanne A.
Abstract:: There could be a geospatial and socio-ecological intersection between climate change, energy production, and sustainable fisheries management in the United States. Marine renewable energy generation efforts are currently being planned, studied, and initially implemented in the country as a response to climate change. The Bureau of Ocean Energy Management is...

The influence of biophysical feedbacks and species interactions on grass invasions and coastal dune morphology in the Pacific Northwest, USA

Creator:: Zarnetske, Phoebe Lehmann
Abstract:: Biological invasions provide a unique opportunity to study the mechanisms that regulate community composition and ecosystem function. Invasive species that are also ecosystem engineers can substantially alter physical features in an environment, and this can lead to cascading effects on the biological community. Aquatic-terrestrial interface ecosystems are excellent systems to...

An Integrated Approach to Gauge the Effects of Global Climate Change on Headwater Stream Ecosystems

Creator:: Bury, Gwendolynn W.
Abstract:: Climate change is predicted to affect ecosystems, including systems already stressed by human impacts. One ecosystem that is already highly impacted by human land use is the cold headwater stream system of the Pacific Northwest. One method of assessing the function of an ecosystem is by using an indicator species....

Cooperation and Conflict Dynamics in Small-Scale Fisheries

Creator:: Villegas, Ciera A.
Abstract:: Small-scale fisheries account for at least 40 percent of global fisheries catch, 90 percent of the people employed along capture fisheries value chains operate in small-scale fisheries, and 45 million women participate in small-scale fisheries globally. The past few years have brought warnings from policymakers and resource managers about risks...

Multiscale assessment of thermal patterns and the distribution of chinook salmon in the John Day River Basin, Oregon

Creator:: Torgersen, Christian E.
Abstract:: This study examined the distribution and behavior of adult spring chinook salmon (Oncorhynchus tshawytscha) related to patterns of stream temperature and physical habitat at channel unit, reach, and basin-wide spatial scales in both a wilderness stream and a disturbed stream in the John Day River basin in northeastern Oregon. Thermal...

Lamprey of the Goose Lake Basin: A Multi-Scale Habitat & Distribution Analysis

Creator:: Dickey, Jacob C.
Abstract:: Two ecologically important lamprey species found in the endorheic Goose Lake Basin face conservation threats; however, relatively little is known about their habitat needs or spatial distribution. Lamprey and their habitat are often found to be patchy; to evaluate these relationships for the lamprey in this basin, I utilized a...

Identifying "at-risk" regions of snow accumulation within California's Sierra Nevada Mountains, and assessing implications on reservoir operations

Creator:: Kalyan, Imtiaz-Ali M.
Abstract:: California's water resources vary throughout the state owing to the regions varying topography, diverse climate, and the distribution of precipitation. Most of the state's precipitation falls over the northern coastal range and the western slopes of the Sierra Nevada Mountains. Winter snowpack that accumulates within these mountain basins serves as...

Distribution and habitat use of bull trout following the removal of nonnative brook trout

Creator:: Renner, Dirk
Abstract:: Invasion by nonnative brook trout (Salvelinus fontinalis) often results in replacement of bull trout (Salvelinus confluentus) in western North America, but the causal mechanisms are not well understood. Removal of brook trout from 1992 to 2000 from Sun Creek in southern Oregon, provided an opportunity to investigate the changes in...

Spatiotemporal Assessment of Crop Histories in the Pacific Northwest

Creator:: Kumbhakar, Ishika G.
Abstract:: The cultivated potato (Solanum tuberosum) is one of the most important food crops in the United States, as well as globally. As demand rises, growers in the Pacific Northwest are revisiting their crop management strategies to determine whether there are additional ways to enhance crop productivity while managing plant and...
