Competing tradeoffs between increasing marine mammal predation and fisheries harvest of Chinook salmon

Creator:: Chasco, Brandon E., Kaplan, Isaac C., Thomas, Austen C., Acevedo-Gutiérrez, Alejandro, Noren, Dawn P., Ford, Michael J., Hanson, M. Bradley, Scordino, Jonathan J., Jeffries, Steven J., Marshall, Kristin N., Shelton, Andrew O., Matkin, Craig, Burke, Brian J., and Ward, Eric J.
Abstract:: Many marine mammal predators, particularly pinnipeds, have increased in abundance in recent decades, generating new challenges for balancing human uses with recovery goals via ecosystem-based management. We used a spatio-temporal bioenergetics model of the Northeast Pacific Ocean to quantify how predation by three species of pinnipeds and killer whales (Orcinus...

Estimates of Chinook salmon consumption in Washington State inland waters by four marine mammal predators from 1970 to 2015

Creator:: Chasco, Brandon E., Kaplan, Isaac C., Thomas, Austen C., Acevedo-Gutiérrez, Alejandro, Noren, Dawn P., Ford, Michael J., Hanson, M. Bradley, Scordino, Jonathan J., Jeffries, Steven J., Pearson, Scott, Marshall, Kristin N., and Ward, Eric J.
Abstract:: Conflicts can arise when the recovery of one protected species limits the recovery of another through competition or predation. The recovery of many marine mammal populations on the west coast of the United States has been viewed as a success; however, within Puget Sound in Washington State, the increased abundance...

The Dynamics and Impact of Ocean Acidification and Hypoxia: Insights from Sustained Investigations in the Northern California Current Large Marine Ecosystem

Creator:: Chan, Francis, Barth, John A., Kroeker, Kristy J., Lubchenco, Jane, and Menge, Bruce A.
Abstract:: Coastal upwelling ecosystems around the world are defined by wind-generated currents that bring deep, nutrient-rich waters to the surface ocean where they fuel exceptionally productive food webs. These ecosystems are also now understood to share a common vulnerability to ocean acidification and hypoxia (OAH). In the California Current Large Marine...

Planning for Change: Assessing the Potential Role of Marine Protected Areas and Fisheries Management Approaches for Resilience Management in a Changing Ocean

Creator:: Kroeker, Kristy J., Carr, Mark H., Raimondi, Peter T., Caselle, Jennifer E., Washburn, Libe, Palumbi, Stephen R., Barth, John A., Chan, Francis, Menge, Bruce A., Milligan, Kristen, Novak, Mark, and White, J. Wilson
Abstract:: Despite progressive policies and continued advances in ocean management, numerous shifts associated with global changes have been observed in marine ecosystems in recent years, including warming, ocean acidification, and deoxygenation. As global change accelerates, science is needed to inform evidence-based management strategies for continued ecosystem services. Resilience management, in which...

Assessing the Impact of Fishery Bait on Spatiotemporal Variation in the Feeding Ecology of Dungeness Crab (Cancer magister) Using Stable Isotopes, Gut Content Analysis & Fishermen Interviews

Creator:: Harbison, Toby N.
Abstract:: The commercial Dungeness crab (Cancer magister) fishery is Oregon’s largest trap-based fishery. Each year, crab vessels discard millions of pounds of bait, including squid, razor clams, and sardines, into the near-coastal ocean. Although the fishery season typically runs from December 1st through August 14th, most landings occur within the first...

Exploring biophysical linkages between coastal forestry management practices and aquatic bivalve contaminant exposure

Creator:: Scully-Engelmeyer, Kaegan, Granek, Elise F., Nielsen-Pincus, Max, Lanier, Andy, Rumrill, Steven S., Moran, Patrick, Nilsen, Elena, Hladik, Michelle L., and Pillsbury, Lori
Abstract:: Terrestrial land use activities present cross-ecosystem threats to riverine and marine species and processes. Specifically, pesticide runoff can disrupt hormonal, reproductive, and developmental processes in aquatic organisms, yet non-point source pollution is difficult to trace and quantify. In Oregon, U.S.A., state and federal forestry pesticide regulations, designed to meet regulatory...

Evolving interest and sense of self in an environmental citizen science program

Creator:: He, Yurong, Parrish, Julia K., Rowe, Shawn, and Jones, Timothy
Abstract:: Citizen science is a growing phenomenon across many branches of environmental science facilitating both increased science literacy and the collection of highly rigorous, longitudinal data. Understanding the motivations of adults to join and remain active in citizen science programs is important as the diversity and abundance of opportunities for public...

Fisheries Connectivity Networks to Measure the Adaptive Capacity of Small-Scale Fisheries in the Baja California Peninsula, Mexico

Creator:: Nomura, Keiko
Abstract:: Small-scale fisheries around the world are increasingly facing pressures from a range of environmental, economic, and social sources. In order to sustain the societal benefits of small-scale fisheries, it is imperative to understand how fishing communities adapt to disturbances. Fishermen often catch multiple different species as an adaptation technique because...
