Applications of slow-moving autonomous platforms for passive acoustic monitoring and density estimation of marine mammals

Creator:: Fregosi, Selene
Abstract:: Advances in mobile autonomous vehicles for oceanographic sensing provide new opportunities for passive acoustic monitoring of marine mammals. Acoustically equipped mobile autonomous platforms, including gliders, deep-water profiling floats, and drifting surface buoys can survey for a variety of marine mammal species over intermediate spatiotemporal scales. Additionally, such mobile platforms may...

The Factors Affecting the Diets of Groundfish in the Gulf of Alaska : Ecological and Modeling Considerations

Creator:: Thompson, Kevin A.
Abstract:: Marine systems undergo changes in community composition over time as a result of a variety of environmental and anthropogenic factors. Understanding these community changes and the factors that drive them is critical for ecosystem management of marine resources. The Gulf of Alaska (GOA) is a large marine ecosystem that includes...

Movement patterns and marine habitat associations of juvenile loggerhead sea turtles (Caretta caretta) in the southwestern Atlantic Ocean

Creator:: Barceló, Caren
Abstract:: Bycatch, or the incidental capture of non-target species, has been implicated as one of the main factors leading to population declines of many large marine vertebrates, including sea turtles. To effectively manage and conserve these long-lived species, their marine distribution, high use areas, foraging habitats, and regions of highest likelihood...

Divergent anti-predator strategies and risk allocation in juveniles of three NorthPacific flatfishes

Creator:: Boersma, Kate S.
Abstract:: Frequent or lengthy predation risk can cause one of two modifications of prey feeding behavior: 1) postponement of feeding to less risky periods, or 2) resumption of feeding behavior despite persistent risk. North Pacific flatfishes exhibit both of these responses when confronted with temporal variation in risk, and this experimental...

Physiological ecology of juvenile Chinook salmon (Oncorhynchus tshawytscha) rearing in fluctuating salinity environments

Creator:: Hackmann, Crystal R.
Abstract:: Estuaries provide juvenile salmonids with highly productive feeding grounds, refugia from tidal fluctuations and predators, and acclimation areas for smoltification. However, these dynamic, fluctuating salinity environments may also be physiologically stressful to growing juvenile fish. In order to evaluate the costs and benefits of estuarine marshes to juvenile Chinook salmon,...

Ecology of the northern subpopulation of northern anchovy (Engraulis mordax) in the California Current large marine ecosystem

Creator:: Litz, Marisa N. C.
Abstract:: Northern anchovy (Engraulis mordax) are a dominant forage fish in the California Current large marine ecosystem (CCLME). However, little is known about northern anchovy abundance, distribution, age structure, or population fluctuations relative to ocean conditions in the eastern boundary upwelling system off the U.S. West Coast. This thesis includes three...

Evaluation of data-poor and age-structure management strategies for west coast rockfish

Creator:: Arnold, Linsey M.
Abstract:: Management strategies to prevent overfishing while achieving optimum yield vary according to the available data and life history of the fished stock. I evaluated two sets of management strategies for Pacific coast rockfish: strategies to set harvest limits for data-poor stocks, and strategies intended to protect the age structure of...

Growth rates and species composition of juvenile rockfish (Sebastes spp.) in Oregon’s nearshore and estuarine habitats

Creator:: Gallagher, M. Brett
Abstract:: Identification of critical habitat for all life stages of commercially exploited fish populations is critical for effective management. Despite a clear need for basic biological information on juvenile rockfish life history, there have been very few efforts to describe distribution and habitat of this life stage, particularly along the Oregon...

Functional Diversity : A Tool to Track Spatiotemporal Changes in the Trophic Organization of Reef Fish Assemblages

Creator:: Rincón Diaz, Martha P.
Abstract:: Biodiversity loss in highly diverse systems such as coral reefs has been linked to significant declines in the ecosystem functions and services provided by marine species. Ecological functioning of coral reefs and the resistance of coral reef fish communities to disturbance depend on the functional traits of species that promotes...

Sequential isotopic analysis to characterize ontogenetic shifts and growth dynamics of loggerhead sea turtles (Caretta caretta)

Creator:: Ramirez, Matthew D.
Abstract:: Ontogenetic niche theory predicts that as organisms grow they make size-specific changes in habitat use and diet to optimize growth and survival. A variety of factors contribute to growth and survival in different habitats, ultimately leading to variation in life history that can affect population dynamics. An understanding of the...
