Genetic Connectivity of the Dungeness Crab (Cancer magister) Across Oceanographic Regimes

Creator:

Roegner, G. Curtis, Corbett, Kelly, Beacham, Terry D., Jacobson, Dave P., Jackson, Tyler M., and O'Malley, Kathleen G.

Abstract:

Limited approaches exist for studying population connectivity in widely dispersing marine benthic invertebrates. Genetic techniques can provide important insights toward identifying recruitment trajectories. Here, 10 microsatellite loci were used to examine connectivity among Oregon Dungeness crabs (Cancer magister, Dana, 1852) in the California Current System (CCS) (n = 801) as...

Bacteriophages Significantly Reduce Mortality of Larval Pacific Oysters Crassostrea gigas from Infection by the Pathogenic Bacterium Vibrio coralliilyticus RE98

Creator:

Madison, David B.

Abstract:

Vibrio coralliilyticus (Vcor) is a bacterial pathogen that is well adapted to shellfish hatcheries and is very pathogenic to the larvae of the Pacific oyster Crassostrea gigas. Vcor has been associated with several large scale larval mortality events in the Pacific Northwest that interrupt the supply of seed oysters available...

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...

Classification of Animal Movement Behavior through Residence in Space and Time

Creator:

Orben, Rachael A., Thompson, David R., Tolkova, Irina, and Torres, Leigh G.

Abstract:

Identification and classification of behavior states in animal movement data can be complex, temporally biased, time-intensive, scale-dependent, and unstandardized across studies and taxa. Large movement datasets are increasingly common and there is a need for efficient methods of data exploration that adjust to the individual variability of each track. We...

Long Term Trends and Sources of Sound in United States Waters

Creator:

Haver, Samara M.

Abstract:

Passive acoustic monitoring is a valuable tool for observing the status of marine environments. Comparisons of underwater soundscapes over temporal and spatial scales can provide data to inform marine conservation efforts, including protection of threatened and endangered species. This dissertation utilizes passive acoustic data collected via a broadly spaced array...

Submersible observations of deep-reef fishes of Heceta Bank, Oregon

Creator:

Pearcy, William G., Stein, David L., Hixon, Mark Anthony, Pikitch, Ellen K., Barss, William H., and Starr, Richard M.

Abstract:

Rockfishes, Sebastes spp.. were the most numerous and speciose fishes seen during 16 submersible dives from 64 to 305 m depth in the vicinity of Heceta Bank off the coast of Oregon. Dense schools of juvenile rockfishes and large yellowtail rockfish, S. flavidus, were observed only over rocky, high relief...

Big fishery, big data, and little crabs: Using genomic methods to examine the seasonal recruitment patterns of early life stage Dungeness crab (Cancer magister) in the California Current Ecosystem

Creator:

Lee, Elizabeth M. J. and O'Malley, Kathleen G.

Abstract:

The California Current Ecosystem (CCE) is a dynamic marine ecosystem from which many socioeconomically important fisheries species are harvested. Here, a genotyping- by-sequencing (GBS) approach was used to examine genomic variation in an early life stage (megalopae) of the Dungeness crab (Cancer magister), which constitutes the most valuable single-species commercial...

Sex matters: Otolith shape and genomic variation in deacon rockfish (Sebastes diaconus)

Creator:

Vaux, Felix, Rasmuson, Leif K., Kautzi, Lisa A., Rankin, Polly S., Blume, Matthew T. O., Lawrence, Kelly A., Bohn, Sandra, and O'Malley, Kathleen G.

Abstract:

Little is known about intraspecific variation within the deacon rockfish (Sebastes di‐ aconus), a recently described species found in the northeast Pacific Ocean. We in‐ vestigated population structure among fish sampled from two nearshore reefs (Siletz Reef and Seal Rock) and one offshore site (Stonewall Bank) within a <50‐km2 area...

Circumpolar Diversity and Geographic Differentiation of mtDNA in the Critically Endangered Antarctic Blue Whale (Balaenoptera musculus intermedia)

Creator:

Sremba, Angela L., Hancock-Hanser, Brittany, Branch, Trevor A., LeDuc, Rick L., and Baker, C. Scott

Abstract:

The Antarctic blue whale (Balaenoptera musculus intermedia) was hunted to near extinction between 1904 and 1972, declining from an estimated initial abundance of more than 250,000 to fewer than 400. Here, we describe mtDNA control region diversity and geographic differentiation in the surviving population of the Antarctic blue whale, using...

An Investigation into the Distribution, Residency Patterns, Population Connectivity, and Abundance of Blue Whales (Balaenoptera musculus) in New Zealand

Creator:

Barlow, Dawn R.

Abstract:

Species conservation depends on robust population assessment. Data on population abundance, distribution, and connectivity are critical for effective management, especially as baseline information for newly documented populations. I describe a pygmy blue whale (Balaenoptera musculus brevicauda) population in New Zealand waters with year-round presence that overlaps with industrial activities. This...
