Susceptibility of juvenile salmonids to avian predation : Are Caspian terns and double-crested cormorants only taking the sick and injured?

Creator:: Hostetter, Nathan J.
Abstract:: The ability to non-destructively assess fish condition and subsequently track fish behavior and survival can be vital in understanding natural and anthropogenic stressors and sources of mortality, especially in populations of fish listed as threatened or endangered. I investigated the use of a quick, non-lethal, external examination technique to assess...

Population Ecology of the Mariana Swiftlet (Aerodramus bartschi) on O'ahu, Hawaiian Islands

Creator:: Johnson, Nathan Christopher
Abstract:: The Mariana Swiftlet (Aerodramus bartschi) (Aves: Apodidae) is endemic to the Mariana Islands, where it currently occurs on Saipan, Aguiguan, and Guam. An introduced population of Mariana Swiftlets is also present on O'ahu in the Hawaiian Islands. Sparing interference with the endangered population in the Marianas, the introduced, surrogate population...

Effects of body size on the survival and timing of emigration of newly metamorphosed Northern Red-legged frogs

Creator:: Chelgren, Nathan D.
Abstract:: The purpose of this study was to investigate the survival and movements of newly metamorphosed Northern Red-legged frogs (Rana aurora aurora) as they emigrated from two ephemeral breeding ponds. Quantifying survival and movement rates will be important to our understanding how changes to terrestrial and aquatic systems affect behavior and...

Ecology of Columbian black-tailed deer fawns in western Oregon

Creator:: Pamplin, Nathan P.
Abstract:: Little is known about Columbian black-tailed deer (Odocoileus hemionus columbianus) because of their elusive nature and the logistical difficulty of studying them in densely forested and mountainous terrain. The Oregon Department of Fish and Wildlife has identified fawn survival as an important gap in the current knowledge of demography and...

Ungulate activity classification : calibrating activity monitor GPS collars for Rocky Mountain elk, mule deer, and cattle

Creator:: Gaylord, Adam J.
Abstract:: Ungulate behavior has been studied extensively but direct observation of free-ranging animals over long periods of time and large geographic areas is often prohibitively difficult. Improved technology, such as GPS collars fitted with motion-sensitive activity monitors, provides researchers with a potential tool to remotely collect fine scale activity and location...

Spatiotemporal Associations of Abundance and Vital Rates of Co-occurring Small Mammals in a Late Successional Forest

Creator:: Weldy, Matthew J.
Abstract:: Informed conservation of small mammals, ecosystems, and predators requires a detailed understanding of how small mammals species and communities vary in both space and time, as well as the relative cyclicity and synchrony of this variation. This variation can be especially informative to land managers interested in manipulating the abundance...

Caspian tern (Hydroprogne caspia) foraging ecology and predation on juvenile salmonids in San Francisco Bay, California

Creator:: Adrean, Lindsay J.
Abstract:: Brooks Island, located in central San Francisco Bay, California, currently supports the largest breeding colony of Caspian terns (Hydroprogne caspia) in the Bay Area, and is one of several proposed relocation sites for some Caspian terns from the world's largest colony in the Columbia River estuary of Oregon. Juvenile salmonids...

Potential barriers to movements and habitat selection of pygmy rabbits (Brachylagus idahoensis) after experimental translocation

Creator:: Lawes, Timothy J. (Timothy James)
Abstract:: I assessed potential barriers to dispersal using homing tendency and investigated the movements and settlement site selection of pygmy rabbits (Brachylagus idahoensis) after short distance translocations in southeastern Oregon from June – December 2008. I captured, radio marked, and translocated 59 pygmy rabbits 1-2 km across landscapes with (1) continuous...

Marine habitat use of black-footed and Laysan albatrosses during the post-breeding season and their spatial and temporal overlap with commercial fisheries

Creator:: Fischer, Karen Naess
Abstract:: Incidental bycatch in commercial fisheries has been identified as a threat to black-footed albatrosses (Phoebastria nigripes) and Laysan albatrosses (P. immutabilis). Effective long-term conservation of these albatrosses necessitates a thorough understanding of their marine distribution, which marine habitats are selected during foraging, and where they are most likely to interact...
