Influence of Novel Ocean Conditions on Life History Characteristics of a Nearshore Rockfish with Implications for Population Assessment and Management

Creator:: Rosemond, Rebecca C.
Abstract:: The California Current Large Marine Ecosystem (CCLME), located on the eastern boundary of the North Pacific Ocean, is highly dynamic, with variable conditions driven by seasonal upwelling, regional oceanography, and broad scale climate patterns. In the last decade, the northeast Pacific Ocean has experienced several marine heatwaves (MHWs), prolonged periods...

Influence of Regional Oceanography on the Distributions, Trophic Interactions, Growth, and Survival of the Early Life History Stages of Fishes

Creator:: Swieca, Kelsey
Abstract:: Most marine fishes experience high rates of mortality during their early life history stages with far reaching consequences for adult population dynamics. Within a few weeks of hatching, relatively small changes in larval growth and mortality rates can lead to orders of magnitude variability in year-class strength. Growth and survival...

Impacts of Ocean Acidification and Warming on the Growth and Development of Oregon Pink Shrimp (Pandalus jordani) Larvae

Creator:: Nguyen, Michelle B.
Abstract:: Anthropogenic carbon dioxide emissions are causing ocean acidification (OA) and ocean warming, which have negative effects on the larvae of many marine invertebrates. Oregon pink shrimp (Pandalus jordani) currently encounter upwelling events that can result in pH values as low as 7.6, and, more recently, marine heat waves that raise...

Maternal effects, the environment, and age structure: A mechanistic fine-scale approach to describe a complex set of factors contributing to larval growth and survival

Creator:: Arnold, Linsey M.
Abstract:: The relationship between population characteristics and population productivity is fundamental to sustainable fisheries management, but predicting productivity remains a challenging task. Proposed mechanisms driving the variability in productivity at a given population size have included environmental and demographic factors related to the age structure of the population, but the broad-scale...

Virtual Element Methods for Magnetohydrodynamics on General Polygonal and Polyhedral Meshes

Creator:: Naranjo, Sebastián
Abstract:: The aim of this dissertation is to construct a virtual element method (VEM) for models in magneto-hydrodynamics (MHD), an area that studies the behavior and properties of electrically conducting ﬂuids such as a plasma. MHD models are a coupling of the Maxwell’s equations for electromagnetics and models for ﬂuid ﬂow....

The Shades of Participation: Assessing the Barriers to Community Participation in Land-Use Decision-Making Processes That Address Environmental Injustices for Low-Income Communities of Color

Creator:: King, Jasmine
Abstract:: Environmental injustices, defined as inequitable access to fair, safe, and healthy environmental outcomes, are often rooted in issues of land management, policy decision making, and sovereignty. This results from a series of processes, including loss of land ownership, exclusionary and discriminatory zoning, and structural barriers to participation. Black, Indigenous, Communities...

Management Applications of Remotely Sensed Dynamic Seascapes: Two Case Studies

Creator:: Klajbor, Willem C.
Abstract:: Dynamic seascapes, which are classified using a combination of remotely sensed data and model output, represent a potential tool for dynamic ecosystem-based management in marine systems. This work explores the utility of seascape classification in the context of marine resource management by examining two case studies: one involving biological relationships...

Accounting for Transient Dynamics Improves use of Marine Protected Areas as a Reference Point for Fisheries Management

Creator:: Quennessen, Victoria I.
Abstract:: Fisheries management that is based on quantitative assessment has commonly relied on estimating the unfished biomass of a fished stock to compare current and historical population size. Developing predictive models for this requires many years of catch and abundance data. Smaller, new, or mainly recreational fisheries may not have the...

Statistical Properties and Guarantees for Certain Anomaly Detection Relevant Problems

Creator:: Liu, Si
Abstract:: Anomaly detection aims at detecting the points that appear different than the majority of the data, such that they are suspected to be generated from a different distribution. Anomaly detectors have been applied in many different fields, such as detecting fraudulent behaviors in bank transaction, finding broken sensors in a...

Plankton food web dynamics and larval fish success : influence of prey and predator distributions on larval fish diet, growth, and assemblages in the Straits of Florida

Creator:: Gleiber, Miram R.
Abstract:: Survival of marine fishes during their early life history stage is tightly related to prey availability and predation pressure. Yet, our understanding of how individual larvae to entire assemblages are constrained by these factors is limited. We integrated biological sampling of larval fishes with fine-scale in situ imaging to relate...

Function of Oregon Estuaries to Juvenile Fishes, with Focus on Juvenile Rockfishes (Sebastes spp.) in Yaquina Bay, Oregon

Creator:: Schwartzkopf, Brittany D.
Abstract:: The role that anthropogenic and natural habitats in estuaries play in long-term population trends for Oregon’s nearshore marine fishes is poorly understood, in part due to limited temporal sampling. One important nearshore marine group is northeastern Pacific rockfishes (Sebastes spp.), which are highly diverse, with around 96 documented species, and...

Faster, Sharper and Open: A New Pipeline for Biota Phantom Creation

Creator:: Neville, Delvan
Abstract:: Anatomically correct biota phantom creation has suffered from three primary weaknesses: the models take considerable time to make, are limited in detail by voxel size, and are created and simulated using proprietary software. Presented are trial runs of a new biota creation pipeline, FSOPhantom, that addresses these issues by creating...

Drivers of Euphausiid Abundance and Biomass in the Kitimat Fjord System, BC Canada

Creator:: Qualls, Katelyn M.
Abstract:: Euphausiids are recognized as essential components of marine food webs throughout the world’s oceans due to their role as prey for many species including whales, seabirds, and commercial fishes. The Kitimat Fjord System is an important fisheries area and is the only fjord habitat on the British Columbia coast that...

Unrealized Economic Benefits in the West Coast Non-Whiting Groundfish Trawl Fishery

Creator:: Gann, Aaron K.
Abstract:: In Oregon, commercial fishing is estimated to contribute $544 million in income and 10,000 jobs per year to coastal communities. However not all fisheries are reaching their allocated quotas for catch. In 2017, 187.6 million pounds of non-whiting groundfish trawl quota worth $67 million was not attained, nearly three times...

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...
