Year-class regulation of mid-upper Columbia River spring Chinook salmon Oncorhynchus tshawytscha : the role of juvenile size, growth, and migratory behavior

Creator:: Tomaro, Londi M.
Abstract:: Early ocean residence is assumed to be a critical period for juvenile Pacific salmon Oncorhynchus spp. However, the specific mechanisms influencing growth and survival in the ocean have not been identified for most populations. Therefore, three hypotheses regarding the relationship between early marine residence and subsequent survival of mid-upper Columbia...

Why aren't pigeon guillemots in Prince William Sound, Alaska recovering from the Exxon Valdez oil spill?

Creator:: Bixler, Kirsten S.
Abstract:: The Pigeon Guillemot (Cepphus columba) is now the only species of marine bird in Prince William Sound (PWS), Alaska that is listed as "not recovering" on the Exxon Valdez Oil Spill (EVOS) Trustee Council's Injured Resources List and has shown no sign of population recovery. During the 20 years since...

Where the Stream Meets the Road : Prioritizing Culvert Replacement for Fish Passage

Creator:: Reagan, Rachel E.
Abstract:: Streams across the world are highly fragmented due to the presence of in-stream barriers (e.g., dams and stream-road crossings), many of which restrict or block fish passage. Retrofitting or replacing these structures is a high priority for restoring habitat connectivity for native fishes and other aquatic organisms in the Pacific...

When is bigger better? Early marine residence of middle and upper Columbia River spring Chinook salmon

Creator:: Tomaro, Londi M., Teel, David J., Peterson, William T., and Miller, Jessica A.
Abstract:: Early ocean residence is considered a critical period for juvenile salmon although specific survival mechanisms are often unidentified and may vary by species or life stage. Columbia River spring-run Chinook salmon Oncorhynchus tshawytscha abundance has declined dramatically since the early 1900s. To elucidate mechanisms of early marine survival, we tested...

Vertebral elemental markers in elasmobranchs : potential for reconstructing environmental history and population structure

Creator:: Smith, Wade D.
Abstract:: Differences in the chemical composition of calcified structures can be used to reveal natal origins, connectivity, metapopulation structure, and reconstruct the environmental history or movement patterns of many marine organisms. Sharks, skates, and rays (elasmobranchs) lack the calcified structures, known as otoliths, that are typically used for geochemical studies of...

Variation in mitochondrial DNA and allozymes discriminates early and late forms of chinook salmon (Oncorhynchus tshawytscha) in the Kenai and Kasilof Rivers, Alaska

Creator:: Adams, Noah Swayambhu
Abstract:: Genetic differences between early and late forms of Alaskan chinook salmon (Oncorhynchus tshawytscha) were identified using two genetic approaches: mitochondrial DNA (mtDNA) analysis and protein electrophoresis. The study populations consisted of early- and late-run chinook salmon in each of the Kenai and Kasilof rivers in Alaska, and a single population...

Value of Prior and Novel Information in Managing a Mixed-Stock Recreational Chinook Salmon Fishery

Creator:: Jensen, Alexander J.
Abstract:: Many economically important Pacific salmon fisheries along the west coast of North America are mixed-stock, recreational systems, in which managers strive to account for interactions between fish, anglers, and management policy while balancing fishery access against conservation of vulnerable stocks. Specific challenges facing fisheries managers include limited control over angling...

Utilization of mineral sites by bandtailed pigeons

Creator:: Passmore, Michael Forrest
Abstract:: The occurrence of band-tailed pigeons (Columba fasciata) three mineral sites in Western Oregon was studied during the summers of 1974-1976. Objectives of the study were o: determine seasonal patterns of utilization of mineral sites by pigeons of different sex and age classes; determine productivity of pigeon populations associated with Mineral...

Using Satellite Imagery to Count Nesting Albatross from Space

Creator:: Dolliver, Jane E.
Abstract:: One fundamental concern in conservation biology is species abundance. For many taxa, however, these data are costly to obtain via direct observation and thus limited in geographic or temporal scope. Very high-resolution satellite imagery provides a means to address these limitations and provide remotely-sensed counts of large, colonial species. We...

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...
