Marine Heatwaves Influence Depth Preferences of Chinook Salmon (Oncorhynchus tshawytscha)

Creator:: Teahan, Andrew
Abstract:: Marine heatwaves have become more common over the past several years. The 2014-2015 ‘warm blob’ had profound effects on marine ecosystems in the Northeast Pacific. Given the particular habitat needs of Chinook Salmon (Oncorhynchus tshawytscha) we wanted to examine the impacts of the heatwave on Chinook depth distribution. We examined...

The use of a species-specific health and welfare assessment tool for the giant pacific octopus, Enteroctopus dofleini

Creator:: Holst, Meghan M. and Miller-Morgan, Tim
Abstract:: Cephalopods are increasingly viewed as sentient animals that require the same welfare consideration as their vertebrate counterparts. In this study, an observational welfare assessment tool developed by the EU Directive was revised to be species-specific for the giant Pacific octopus, Enteroctopus dofleini. This E. dofleini health and welfare assessment tool...

Elemental Markers in Elasmobranchs: Effects of Environmental History and Growth on Vertebral Chemistry

Creator:: Smith, Wade D., Miller, Jessica A., and Heppell, Selina S.
Abstract:: Differences in the chemical composition of calcified skeletal structures (e.g. shells, otoliths) have proven useful for reconstructing the environmental history of many marine species. However, the extent to which ambient environmental conditions can be inferred from the elemental signatures within the vertebrae of elasmobranchs (sharks, skates, rays) has not been...

Prey dominance shapes trophic structure of the northern California Current pelagic food web: evidence from stable isotopes and diet analysis

Creator:: Miller, Todd W., Brodeur, Richard D., Rau, Greg, and Omori, Koji
Abstract:: Eastern boundary current (EBC) upwelling zones are among the most productive of marine ecosystems globally and have been generalized in terms of their food web structure. Little empirically based evidence exists to suggest that there is any one form of trophic control of EBC systems and, because of logistical constraints,...

Comparative Aquatic Toxicology of Pesticides and Plastics Using the Model Estuarine Fish, Inland Silverside

Creator:: Hutton, Sara J.
Abstract:: Based on current trends both pesticide and plastic production are expected to continue to rise in the coming decade. A growing global population coupled with the effects of climate change are the main drivers of increased pesticide use. Throughout this dissertation pesticides refer to herbicides, fungicides, and insecticides. Plastic production...

Spatial and Temporal Assessment of Vertically Migrating Myctophids as Biotransporters of Microplastics to Mesopelagic Food Webs

Creator:: Boisen, Olivia C.
Abstract:: It is well documented that microplastics and semi-synthetic particles (<5 mm) pervade the marine environment, with their ingestion by marine fauna eliciting global concern. While fishes exposed to microparticles in a laboratory setting have exhibited both sub-lethal and lethal effects, the diversity in material, morphology, and size of these contaminants...

Long Term Trends and Sources of Sound in United States Waters

Creator:: Haver, Samara M.
Abstract:: Passive acoustic monitoring is a valuable tool for observing the status of marine environments. Comparisons of underwater soundscapes over temporal and spatial scales can provide data to inform marine conservation efforts, including protection of threatened and endangered species. This dissertation utilizes passive acoustic data collected via a broadly spaced array...

A New Record of Planktic Foraminifera Community Response to Marine Heatwaves in the Northeast Pacific

Creator:: M. Kelsey Lane
Abstract:: Marine heat waves are forecasted to increase in frequency and intensity under future climate scenarios, but little is known about the impact of these events on the one of the most commonly used proxies of ocean temperature - foraminiferal assemblages. This research explores the planktic foraminifera community along the Newport...

An Investigation into the Distribution, Residency Patterns, Population Connectivity, and Abundance of Blue Whales (Balaenoptera musculus) in New Zealand

Creator:: Barlow, Dawn R.
Abstract:: Species conservation depends on robust population assessment. Data on population abundance, distribution, and connectivity are critical for effective management, especially as baseline information for newly documented populations. I describe a pygmy blue whale (Balaenoptera musculus brevicauda) population in New Zealand waters with year-round presence that overlaps with industrial activities. This...
