A comprehensive approach for habitat restoration in the Columbia Basin

Creator:: Rieman, Bruce E., Smith, Courtland L., Naiman, Robert J., Ruggerone, Gregory T., Wood, Christ C., Huntly, Nancy, Merril, Erik N., Alldredge, J. Richard, Bisson, Peter A., Congleton, James, Fausch, Kurt D., Levings, Colin, Pearcy, William, Scarnecchia, Dennis, and Smouse, Peter
Abstract:: The Columbia Basin once supported a diversity of native fishes and large runs of anadromous salmonids that sustained substantial fisheries and cultural values. Extensive land conversion, watershed disruptions, and subsequent fishery declines have led to one of the most ambitious restoration programs in the world. Progress has been made, but...

The distribution and aggregation of Chinook salmon stocks on the Oregon Shelf as indicated by the commercial catch and genetics

Creator:: Ireland, Robert
Abstract:: Project CROOS, Collaborative Research on Oregon Ocean Salmon, is a unique partnership of scientists and commercial fishermen that combines catch location data with stock assignments obtained from genetic micro-satellite analysis to investigate the distribution of Oregon Chinook across multiple spatial scales. Using catch data collected by collaborating Oregon troll fishermen,...

Bio-physical interactions of small pelagic fish schools and zooplankton prey in the California Current System over multiple scales

Creator:: Kaltenberg, Amanda May
Abstract:: Small pelagic fish represent a critical trophic link between plankton and large predators in marine upwelling ecosystems such as the California Current System. Populations of these fish are highly variable over time and are characterized by extreme fluctuations in abundance, which have significant ecosystem impacts. The causes driving this instability...

Bioenergetics individual based model explorations of juvenile coho salmon growth during their first summer on the Oregon shelf

Creator:: Reser, Brendan Alexander
Abstract:: Salmon survival and eventual recruitment success have long been thought to be determined within the first summer following ocean migration. Juvenile growth during this period is largely influenced by ocean conditions such as temperature, prey availability, abundance, and quality. Shifts in these conditions due to climatic perturbations are particularly prevalent...

Are there two subgroups of albacore, Thunnus alalunga, in the North Pacific? Evidence from variability in catch, seasonal migrations, and length composition for two subgroups in the coastal fishery of North America

Creator:: Barr, Charles M.
Abstract:: North Pacific albacore (Thunnus alalunga) is a highly migratory and commercially valuable species of tuna. All stock assessments and management decisions for North Pacific albacore are presently based on the assumption of a single, uniform stock. However, a growing body of evidence from diverse sources suggests that there are two...

Integration of oceanographic information off the Washington and Oregon coasts into west coast groundfish ecology and fisheries management

Creator:: Juan Jorda, Maria Jose
Abstract:: To date, the use of oceanographic data in fisheries management has been limited by the scarcity and the difficulty of accessing complete oceanographic datasets. Consequently, fish stocks are managed with limited knowledge about the habitat where fish live and incomplete understanding of what oceanographic conditions affect their populations. With the...

Distribution, structure, and function of marine ecological communities in the northern California Current upwelling ecosystem

Creator:: Reese, Douglas Charles
Abstract:: Within systems characterized by substantial spatial and temporal variability, abundances of organisms tend to be higher in localized areas. Within the northern California Current system, the identification of such marine, biological hotspots would be of great importance to resource managers, conservationists, and research planners, and is consequently a growing area...

Comparative study of the population dynamics, secondary productivity, and reproductive ecology of the euphausiids Euphausia pacifica and Thysanoessa spinifera in the Oregon upwelling region

Creator:: Gutierrez, Jaime Gomez
Abstract:: I compare the seasonal abundance variation, population dynamics, fecundity, egg hatching mechanism and success, and apostome ciliate parasites of the euphausiids Euphausia pac?fica and Thysanoessa spinfera from the Oregon coast, USA. Community structure and nearshore distributions were examined from bi-weekly oceanographic surveys (1970-1972). This region has a strong cross-shelf change...

Oceanographic conditions around the Galápagos Archipelago and their influence on cetacean community structure

Creator:: Palacios, Daniel Mauricio
Abstract:: The objectives of this dissertation were to describe the complex oceanographic conditions around the Galápagos Archipelago (eastern equatorial Pacific), their seasonal variability, and their effects on patterns of cetacean occurrence. The physical and ecological factors leading to a plume of high phytoplankton biomass in the wake of the Galápagos were...

El Nino related variations in nutrient and chlorophyll distributions off Oregon

Creator:: Corwith, Holly L.
Abstract:: The Oregon continental shelf waters are typically characterized by four to five major upwelling events that occur between May and October. The upwelled water is rich in nutrients, which fuels an increase in phytoplankton biomass. The onset of El Nino, however, can disrupt the normal physical processes along the Oregon...
