Identification of optimal broodstock for Pacific Northwest oysters

Creator:: Stick, David A.
Abstract:: The United States Pacific Northwest is well known for its shellfish farming. Historically, commercial harvests were dominated by the native Olympia oyster, Ostrea lurida, but over-exploitation, habitat degradation, and competition and predation by non-native species has drastically depleted their densities and extirpated many local populations. As a result, shellfish aquaculture...

Electrofishing mark-recapture and depletion methodologies evoke behavioral and physiological changes in cutthroat trout (Oncorhynchus clarki)

Creator:: Mesa, Matthew G.
Abstract:: We examined the behavioral and physiological responses of wild and hatchery-reared cutthroat trout Oncorhynchus clarki subjected to a single electroshock, electroshock plus marking, and multiple electroshocking in natural and artificial streams. In a natural stream, trout released after capture by electrofishing and marking showed distinct behavioral changes: fish immediately sought...

Mark-recapture estimates of population parameters for selected species of small mammals

Creator:: Hammond, Ellen L.
Abstract:: I used program CAPTURE to analyze 1,535 data sets for 33 North American species of small mammals for sources of variation in capture probabilities and to characterize species-specific responses to markrecapture trapping. CAPTURE incorporates seven models to account for all possible combinations of heterogeneity (h), behavioral response (b), and time...

Prey preference of lingcod (Ophiodon elongatus), a top marine predator : implications for ecosystem-based fisheries management

Creator:: Tinus, Craig A.
Abstract:: Many highly exploited ecosystems are managed on the basis of single-species demographic information. This management approach can exacerbate tensions among stakeholders with competing interests who in turn rely on data with notoriously high variance. In this case study, an application of diet and dive survey data was used to describe...

Supplemental data to "Estimating the Genetic Diversity of Pacific salmon and trout using Multi-gene eDNA Metabarcoding"

Creator:: Weitemier, Kevin A.
Abstract:: This dataset contains DNA sequence data of Oncorhynchus species, isolated from environmental DNA (eDNA) from Pacific Northwest streams via microfluidic eDNA metabarcoding and high-throughput (Ilummina) sequencing (samples collected from 2017-09-22 to 2017-10-10). It is accompanied by scripts and commands for data analyses including: sequence denoising, calculation of entropy values by...

A Meta-Analysis of Lesser Prairie-Chicken Nesting and Brood-Rearing Habitats: Implications for Habitat Management

Creator:: Hagen, Christian A., Grisham, Blacke A., Boal, Clint W., and Haukos, David A.
Abstract:: The distribution and range of lesser prairie-chicken (Tympanuchus pallidicinctus) has been reduced by >90% since European settlement of the Great Plains of North America. Currently, lesser prairie-chickens occupy 3 general vegetation communities: sand sagebrush (Artemisia filifolia), sand shinnery oak (Quercus havardii), and mixed-grass prairies juxtaposed with Conservation Reserve Program grasslands....

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....

Site tenacity, mate retention and sexual dimorphism in Black Terns

Creator:: Stern, Mark A.
Abstract:: Between 1982-1984 I studied site tenacity and mate retention in Black Terns at Sycan Marsh, Lake County, Oregon. I banded 778 adult Black Terns and used this marked population to test the hypotheses that site tenacity and mate retention would be less for Black Terns which nest in variable marsh...

Short-tailed weasel space use in managed forests of western Oregon

Creator:: Linnell, Mark A.
Abstract:: Although short-tailed weasels (Mustela erminea) are important predators of small mammals, little is known about their space use, habitat selection, or vulnerability to predation in North America. To evaluate the effects of forest management and social structure on home range size and habitat selection of short-tailed weasels, I conducted a...

A new species of western Atlantic lizardfish (Teleostei: Synodontidae: Synodus) and resurrection of Synodus bondi Fowler, 1939, as a valid species from the Caribbean with redescriptions of S. bondi, S. foetens (Linnaeus, 1766), and S. intermedius (Agassiz, 1829)

Creator:: Frable, Benjamin W., Baldwin, Carole C., Luther, Brendan M., and Weigt, Lee A.
Abstract:: Western Atlantic synodontid species were studied as part of an ongoing effort to reanalyze Caribbean shorefish diversity. A neighbor-joining tree constructed from cytochrome c oxidase I (COI) data revealed 2 highly divergent genetic lineages within both Synodus intermedius (Agassiz, 1829) (Sand Diver) and S. foetens (Linnaeus, 1766) (Inshore Lizardfish).
