Genetic Connectivity of Dungeness Crab (Cancer magister) in the California Current System and Puget Sound

Creator:: Jackson, Tyler M.
Abstract:: Understanding connectivity among exploited populations is critical to their sustainable management and long-term viability. In the marine environment, estimates of connectivity often rely on the use of genetic markers, as dispersal primarily occurs during a planktonic larval phase which is difficult to track using direct methods. In this thesis, we...

Big Fishery, Big Data, and Little Crabs: Using a Genomic Approach to Examine Larval Recruitment Patterns of Dungeness Crab (Cancer magister) in the California Current Ecosystem

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

Characterizing Fine-Scale Neutral and Adaptive Genetic Diversity of Oncorhynchus mykiss in the Klamath Basin Before Dam Removal

Creator:: Piotrowski, Stanley J.
Abstract:: An inextricable link exists between dams and human development in the Pacific Northwest, but they can fragment rivers and reduce genetic connectivity for freshwater and anadromous fishes. Since the early-twentieth century, a series of hydropower and irrigation dams on the mainstem Klamath River, California, has fragmented migratory corridors and eliminated...

Mate choice of wild spawning coho salmon (Oncorhynchus kisutch) in the Umpqua River, Oregon

Creator:: Whitcomb, Amelia C.
Abstract:: Evidence for reduced reproductive success (RS) of wild spawning hatchery-reared fish invites serious consideration with regard to the detrimental effects on subsequent generations of wild populations. Mate choice was evaluated as a potential mechanism contributing to these observed RS differences using a previous pedigree of wild spawning hatchery-reared and wild...

An investigation into the genetic basis of migration timing in Chinook salmon (Oncorhynchus tshawytscha)

Creator:: O'Malley, Kathleen G.
Abstract:: The genetic basis of adaptation is complex as many fitness-related traits are quantitative and likely influenced by multiple genes with variable effects across different selective environments. One important adaptation for anadromous Chinook salmon (Oncorhynchus tshawytscha) is the time at which individuals return to natal breeding sites within a reproductive season....

Use of Landscape Characteristics to Quantify Hybridization Risk Between Native and Introduced Salmonids

Creator:: Manning, Michael A.
Abstract:: The introduction of non-native species can negatively impact native species through reduced genetic fitness resulting from hybridization. The lack of spatiotemporal data of hybrids occurrences makes assessing hybridization risk difficult. Here, I developed a spatially-explicit GIS Hybridization Risk Model (HRM) between native ESA-listed Bull Trout and introduced Brook Trout by...

Comparing genetic connectivity among Dungeness crab (Cancer magister) inhabiting Puget Sound and coastal Washington

Creator:: Jackson, Tyler M. and O’Malley, Kathleen G.
Abstract:: Understanding connectivity of marine organisms is necessary for determining the appropriate scale of conservation and management strategies. For species that inhabit both the coastal ocean and partially enclosed water bodies (i.e., estuaries or fjords), this information is even more critical since estuaries and fjords are often characterized by hydrological complexities...

The influence of local fidelity and recruitment on population dynamics and specialized foraging of humpback whales in Glacier Bay and Icy Strait, Alaska

Creator:: Pierszalowski, Sophie Penny
Abstract:: Humpback whales (Megaptera novaeangliae, Borowski 1781) in the North Pacific migrate from mid- to high- latitude summer feeding grounds along the Pacific Rim, including areas off the coasts of the U.S., Canada, Russia and eastern Asia, to tropical breeding grounds each winter along Pacific coasts of Mexico and Central America...

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...

Evidence for interannual variation in genetic structure of Dungeness crab (Cancer magister) along the California Current System

Creator:: Jackson, Tyler M., Roegner, G. Curtis, and O'Malley, Kathleen G.
Abstract:: Using a combination of population‐ and individual‐based analytical approaches, we provide a comprehensive examination of genetic connectivity of Dungeness crab (Cancer magister) along ~1,200 km of the California Current System (CCS). We sampled individuals at 33 sites in 2012 to establish a baseline of genetic diversity and hierarchal population genetic...
