The silence of the clams: Forestry registered pesticides as multiple stressors on soft-shell clams

Creator:: Tissot, Alexandra G., Granek, Elise F., Thompson, Anne W., Hladik, Michelle L., Moran, Patrick W., and Scully-Engelmeyer, Kaegan
Abstract:: Contaminants are ubiquitous in the environment, often reaching aquatic systems. Combinations of forestry use pesticides have been detected in both water and aquatic organism tissue samples in coastal systems. Yet, most toxicological studies focus on the effects of these pesticides individually, at high doses, and over acute time periods, which,...

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...

Temporally balanced selection during development of larval Pacific oysters (Crassostrea gigas) inherently preserves genetic diversity within offspring

Creator:: Durland, Evan, De Wit, Pierre, and Langdon, Chris
Abstract:: Balancing selection is one of the mechanisms which has been proposed to explain the maintenance of genetic diversity in species across generations. For species with large populations and complex life histories, however, heterogeneous selection pressures may create a scenario in which the net effects of selection are balanced across developmental...

A doubled down invasion of the northeast Pacific by the Asian mud shrimp, Upogebia major and its coevolved bopyrid isopod parasite, Orthione griffenis

Creator:: Chapman, John W., Li, Jingchun, McGowan, Michael F., Breitenstein, Ralph A., Appy, Ralph, Hieb, Kathryn A., Piotrowski, Christina N., and Elder, Leanne E.
Abstract:: Dramatic declines of the native northeast Pacific mud shrimp, Upogebia pugettensis over the last three decades have occurred in response to intense infestations by the Asian bopyrid isopod parasite, Orthione griffenis, that was introduced in the 1980s. We report herein the arrival of the Asian mud shrimp, Upogebia major, in...

Sablefish (Anoplopoma fimbra Pallas, 1814) plasma biochemistry and hematology reference intervals including blood cell morphology

Creator:: Schubiger, Carla B., Gorman, M. Elena, Johns, Jennifer L., Arkoosh, Mary R., and Dietrich, Joseph P.
Abstract:: Plasma biochemistry and hematology reference intervals are integral health assessment tools in all medical fields, including aquatic animal health. As sablefish (Anoplopoma fimbria) are becoming aquaculturally and economically more important, this manuscript provides essential reference intervals (RI) for their plasma biochemistry and hematology along with reference photomicrographs of blood cells...

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...

Discovery of a dune-building hybrid beachgrass (Ammophila arenaria × A. breviligulata) in the U.S. Pacific Northwest

Creator:: Mostow, Rebecca S., Barreto, Felipe, Biel, Reuben, Meyer, Eli, and Hacker, Sally D.
Abstract:: The production of novel hybrid zones is an ecologically important consequence of globally increasing rates of species introductions and invasions. Interspecific hybridization can facilitate gene flow between parent species or produce novel taxa that may alter invasion dynamics or ecosystem services. The coastal sand dunes of the U.S. Pacific Northwest...

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...

Quantifying uncertainty in exposure to coastal hazards associated with both climate change and adaptation strategies : a U.S. Pacific Northwest alternative coastal futures analysis

Creator:: Mills, Alexis K., Ruggiero, Peter, Bolte, John P., Serafin, Katherine A., and Lipiec, Eva
Abstract:: Coastal communities face heightened risk to coastal flooding and erosion hazards due to sea-level rise, changing storminess patterns, and evolving human development pressures. Incorporating uncertainty associated with both climate change and the range of possible adaptation measures is essential for projecting the evolving exposure to coastal flooding and erosion, as...

Larval development in the Pacific oyster and the impacts of ocean acidification : differential genetic effects in wild and domesticated stocks

Creator:: Durland, Evan, Pierre De Wit,, Meyer, Eli, and Langdon, Chris
Abstract:: The adaptive capacity of marine calcifiers to ocean acidification (OA) is a topic of great interest to evolutionary biologists and ecologists. Previous studies have provided evidence to suggest that larval resilience to high pCO2 seawater for these species is a trait with a genetic basis and variability in natural populations....
