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...

Large medusae in surface waters of the Northern California Current: variability in relation to environmental conditions

Creator:: Suchman, Cynthia L., Brodeur, Richard D., Daly, Elizabeth A., and Emmett, Robert L.
Abstract:: Blooms of jellyfish around the world have been correlated with climatic variables related to environmental causes. Sizeable populations of large medusae, primarily Chrysaora fuscescens and Aequorea sp., appear annually in shelf waters of the Northeast Pacific Ocean. Previous research has shown that C. fuscescens is abundant seasonally in the inner...

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...

Species composition and community structure of pelagic nekton off Oregon and Washington under variable oceanographic conditions

Creator:: Brodeur, Richard D., Fisher, Joseph P., Emmett, Robert L., Morgan, Cheryl A., and Casillas, Ed
Abstract:: Dramatic changes in the physical and biological conditions off Washington and Oregon, USA, have occurred since 1998, including extreme El Niño (warm) and La Niña (cool) years, high and low Columbia River flow years, a major intrusion of subarctic water, and a low oxygen event on the shelf. The occurrence...

Vertical Zoning in Marine Protected Areas: Ecological Considerations for Balancing Pelagic Fishing with Conservation of Benthic Communities

Creator:: Grober-Dunsmore, Rikki, Wooninck, Lisa, Field, John, Ainsworth, Cameron, Beets, Jim, Berkeley, Steve, Bohnsack, Jim, Boulon, Rafe, Brodeur, Richard, Brodziak, John, Crowder, Larry, Gleason, Danny, Hixon, Mark, Kaufman, Les, Lindberg, Bill, Miller, Marc, Morgan, Lance, and Wahle, Charles
Abstract:: Marine protected areas (MPAs), ideally, manage human uses that threaten ecosystems, or components of ecosystems. During several recent MPA designation processes, concerns have arisen over the scientific justification for no-take MPAs, particularly those that restrict recreational fishing for pelagic species. An important question is: under what conditions might recreational pelagic...

State of the California Current 2011–2012: Ecosystems Respond To Local Forcing as La Nina Wavers and Wanes

Abstract:: The state of the California Current System (CCS) since spring 2011 has evolved in response to dissipation of La Niña through spring and summer, resurgence of cooler La Niña conditions in fall and winter, and finally a transition towards ENSO-neutral conditions in spring 2012. The resurgence of La Niña was...

Status of the European Green Crab, Carcinus maenas, in Oregon and Washington coastal Estuaries. Report for 2020 and 2021

Creator:: Yamada, Sylvia Behrens, Royer, Cameron, Schooler, Shon, Fisher, Jennifer, Randall, Andrea, Buffington, Chelsey, Stote, Alex, and Akmajian, Adrianne
Abstract:: The European green crab (Carcinus maenas) has persisted in Oregon and Washington coastal estuaries since the late 1990s. A strong year class arrived in the Davidson Current during the 1998 El Niño, but numbers decreased and remained below 1 per trap per day until the arrival of the 2015-2016 El...
