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...

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...

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...

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...

Population Structure and Phylogeography in Nassau Grouper (Epinephelus striatus), a Mass-Aggregating Marine Fish

Creator:: Jackson, Alexis M., Semmens, Brice X., de Mitcheson, Yvonne Sadovy, Nemeth, Richard S., Heppell, Scott A., Bush, Phillippe G., Aguilar-Perera, Alfonso, Claydon, John A. B., Calosso, Marta C., Sealey, Kathleen S., Schärer, Michelle T., and Bernardi, Giacomo
Abstract:: To address patterns of genetic connectivity in a mass-aggregating marine fish, we analyzed genetic variation in mitochondrial DNA (mtDNA), microsatellites, and single nucleotide polymorphisms (SNPs) for Nassau grouper (Epinephelus striatus). We expected Nassau grouper to exhibit genetic differentiation among its subpopulations due to its reproductive behavior and retentive oceanographic conditions...

Enzyme-Linked Immunosorbent Assay (ELISA) of Vitellogenin in Temperate Basses (Genus Morone): Plasma and In Vitro Analyses

Creator:: Heppell, Scott A., Jackson, Leslie F., Weber, Gregory, M., and Sullivan, Craig, V.
Abstract:: Blood levels of the egg yolk precursor vi- tellogenin (VTG) can be used as a deﬁnitive marker for the onset and progress of maturation in female teleosts. In the present study, an enzyme-linked immunosorbent assay (ELISA) was developed to measure VTG in blood plasma from three species of temperate basses....

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...

Impact of land use patterns and agricultural practices on water quality in the Calapooia River Basin of western Oregon

Creator:: Mueller-Warrant, G. W., Griffith, S. M., Whittaker, G. W., Banowetz, G. M., Pfender, W. F., Garcia, T. S., and Giannico, G. R.
Abstract:: Agricultural practices, including tillage, fertilization, and residue management, can affect surface runoff, soil erosion, and nutrient cycling. These processes, in turn, may adversely affect (1) quality of aquatic resources as habitat for amphibians, fish, and invertebrates, (2) costs of treating surface and ground water to meet drinking water standards, and...

Survival and Home-range Size of Northern Spotted Owls in Southwestern Oregon

Creator:: Schilling, Jason W., Dugger, Katie M., and Anthony, Robert G.
Abstract:: In the Klamath province of southwestern Oregon, Northern Spotted Owls (Strix occidentalis caurina) occur in complex, productive forests that historically supported frequent fires of variable severity. However, little is known about the relationships between Spotted Owl survival and home-range size and the characteristics of fire-prone, mixed-conifer forests of the Klamath...

Population trends in northern spotted owls: Associations with climate in the Pacific Northwest

Creator:: Glenn, Elizabeth M., Anthony, Robert G., and Forsman, Eric D.
Abstract:: We used reverse time capture-mark-recapture models to describe associations between rate of population change (λ) and climate for northern spotted owls (Strix occidentalis caurina) at six long-term study areas in Washington and Oregon, USA. Populations in three of six areas showed strong evidence of declining populations, while populations in two...
