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...

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...

Ecology and Distribution of Blue Whales in New Zealand Across Spatial and Temporal Scales

Creator:: Barlow, Dawn R.
Abstract:: The distribution of mobile marine predators often reflects underlying dynamic ecological processes. The geographical focus of this PhD is the South Taranaki Bight (STB) of New Zealand, where wind-driven coastal upwelling generates productivity and prey to support a blue whale foraging ground. The STB is also New Zealand’s most industrial...

Marine, Estuarine, and Diadromous Fish Stocks at Risk of Extinction in North America (Exclusive of Pacific Salmonids)

Creator:: Musick, J. A., Harbin, M. M., Berkeley, S. A., Burgess, G. H., Eklund, A. M., Findley, L., Gilmore, R. G., Golden, J. T., Ha, D. S., Huntsman, G. R., McGovern, J. C., Sedberry, G. R., Parker, S. J., Poss, S. G., Sala, E., Schmidt, T. W., Weeks, H., and Wright, S. G.
Abstract:: The problem of extinction in the sea has been recognized only recently by the scientific community (Roberts and Hawkins 1999). For the last decade, the American Fisheries Society (AFS) has pursued an initiative to identify marine fish stocks that may be at risk of extinction in North America (Musick 1998;...

Skin Deep: An Assessment of New Zealand Blue Whale Skin Condition

Creator:: Barlow, Dawn R., Pepper, Acacia L., and Torres, Leigh G.
Abstract:: Skin condition assessment of wildlife can provide insight into individual and population health. Yet, logistics can limit skin condition assessment of large whales. We developed a standardized, quantitative protocol using photographs to assess skin condition of blue whales in New Zealand, and demonstrate the value gained by testing hypotheses, documenting...

Hydrothermal activity in the Northwest Lau Backarc Basin: Evidence from water column measurements

Creator:: Lupton, J. E., Arculus, R. J., Resing, J., Massoth, G. J., Greene, R. R., Evans, L. J., and Buck, N.
Abstract:: The Northwest Lau Backarc Basin, consisting of the Northwest Lau Spreading Center (NWLSC) and the Rochambeau Rifts (RR), is unique in having elevated ³He/⁴He ratios (up to 28 R[subscript a]) in the erupted lavas, clearly indicating a hot spot or ocean island basalt (OIB)-type signature. This OIB-type helium signature does...

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...

An Evaluation of the Influence of Stock Origin and Outmigration History on the Disease Susceptibility and Survival of Juvenile Chinook Salmon

Creator:: Dietrich, Joseph P., Boylen, Deborah A., Thompson, Donald E., Loboschefsky, Erik J., Bravo, Claudia F., Spangenberg, Dina K., Ylitalo, Gina M., Collier, Tracy K., Fryer, Derek S., Arkoosh, Mary R., and Loge, Frank J.
Abstract:: Various methods have been developed to mitigate the adverse effects of the Federal Columbia River Power System on juvenile Pacific salmon out-migrating through the Columbia River basin. In this study, we found that hatchery-reared spring Chinook salmon Oncorhynchus tshawytscha in the river are in varying degrees of health, which may...

The application of GIS and spatiotemporal analyses to investigations of unusual marine mammal strandings and mortality events

Creator:: Norman, Stephanie A., Huggins, Jessie, Carpenter, Tim E., Case, James T., Lambourn, Dyanna M., Rice, Jim, Calambokidis, John, Gaydos, Joseph K., Hanson, M. Bradley, Duffield, Deborah A., Dubpernell, Sandra, Berta, Susan, and Klope, Matt
Abstract:: In 2006–2007, an unusually high number of harbor porpoises (Phocoena phocoena) stranded along the Washington and Oregon coastlines. Spatiotemporal analyses were used to examine their ability to detect clusters of porpoise strandings during an unusual mortality event (UME) in the Pacific Northwest using stranding location data. Strandings were evaluated as...
