Combining Disparate Data Sources with Ecosystem and Integrated Models: Case Studies for Improving Management of Protected Species

Creator:: Chasco, Brandon E.
Abstract:: Globally, the number of threatened species is increasing and conserving them is a high priority to the scientific community. Assessing the status of these protected species is challenging due to missing, contested, and or contradictory data streams. Integrated models (IMs) provide a statistical framework for combining disparate data sources to...

Development of the fisheries of the Eastern North Pacific : a natural-cultural systems perspective

Creator:: Deimling, Elisabeth A.
Abstract:: The eastern margin of the Eastern North Pacific Ocean was classified into physiographic regions based on a suite of physical characteristics. Information on cultural and biological characteristics of this area was meshed with this classification. The result was a classification of the Eastern North Pacific into natural-cultural systems whose boundaries...

Effects of Stage 0 Stream Restoration on Aquatic Macroinvertebrate Production

Creator:: Jennings, Jeremy C.
Abstract:: Contemporary stream restoration efforts increasingly prioritize restoring natural stream processes to regain lost ecosystem functions. Stage 0 stream restoration resets disturbed, channelized streams to a theoretical pre-disturbance state (“stage zero”). It is assumed that this valley-scale restoration/disturbance will restore natural abiotic and biotic processes, leading to greater primary and secondary...

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...

Evaluation of length distributions and growth variance to improve assessment of the loggerhead sea turtle, (Caretta caretta)

Creator:: Vaughan, Jason R.
Abstract:: Nest counts from the largest subpopulation of the loggerhead sea turtle (Caretta caretta) in the Atlantic, peninsular Florida, have been declining since 1998. Analyzing trends of nests and adult females is insufficient to determine the overall status of a sea turtle population, due to variation in nesting frequency and a...

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...

An Evaluation of the Effects of the Parasite Salmincola californiensis on At-Risk Chinook Salmon Populations

Creator:: Gardner, Ethan N.
Abstract:: Once abundant in their native range, Pacific salmon species (Oncorhynchus spp.) were widely distributed across the northern Pacific Rim from South Korea and Japan to the Sacramento River in California. Remaining populations are subject to population-level threats, including pathogens. The freshwater parasitic copepod Salmincola californiensis is associated with the reduced...

Otolith Morphometrics as a Tool for Conservation and Management of Chinook Salmon (Oncorhynchus tshawytscha)

Creator:: Koeberle, Alexander L.
Abstract:: Chinook salmon are widely distributed across the globe with native stocks in the North Pacific Ocean and self-sustained populations introduced to regions in the Northern and Southern Hemispheres. Pacific salmon are economically and ecologically important to the Pacific Northwest, USA, yet several wild populations are federally listed as endangered or...

Relationship between Ascarophis Sp. (Nematoda: Cystidicolidae), Sturgeon Feeding Pit Density and Ghost Shrimp Burrowing Behavior

Creator:: Brockman, Joseph N.
Abstract:: Bioturbation caused by ghost shrimp, Neotrypaea californiensis, burrowing activity can negatively affect Pacific oyster, Crassostrea gigas, aquaculture through their burial and subsequent suffocation. The shellfish aquaculture industry used chemicals to control burrowing shrimp populations in Washington State estuaries for decades, but, due to public and governmental scrutiny, that practice has...

A Low-Volume Flow-Through System for Rearing Pacific Oyster (Crassostrea gigas) Larvae

Creator:: Fleener, Henry R.
Abstract:: Standard larval Pacific oyster (Crassostrea gigas) rearing systems can be described as either static or continuous flow. While rearing oyster larvae in static cultures can be a low-cost and simple method, static systems require significant husbandry effort, floorspace and can produce highly variable results due to environmental variance among cultures....
