Ecohydrologic Connections in Semiarid Watershed Systems of Central Oregon USA

Creator:: Ochoa, Carlos G., Caruso, Phil, Ray, Grace, Deboodt, Tim, Jarvis, W. Todd, and Guldan, Steven J.
Abstract:: An improved understanding of ecohydrologic connections is critical for improving land management decisions in water-scarce regions of the western United States. For this study, conducted in a semiarid (358 mm) rangeland location in central Oregon, we evaluated precipitation-interception-soil moisture dynamics at the plot scale and characterized surface water and groundwater...

Spatiotemporal distribution of the anti-diabetic drug, metformin, in the lower Columbia River and its effect on phytoplankton growth

Creator:: Cummings, Brittany M.
Abstract:: Water quality impacts both human and ecosystem health. Many pharmaceuticals and personal care products are considered contaminants of emerging concern (CEC) due to their bioactive properties. Among these, metformin—the most commonly prescribed drug for treatment of type 2 diabetes—has been reported at high concentrations (μg L⁻¹) in stream, lake, and...

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

Creator:: Acevedo-Gutiérrez, Alejandro, Chasco, Brandon E., Ward, Eric J., Ford, Michael J., Shelton, Andrew O., Thomas, Austen C., Burke, Brian J., Marshall, Kristin N., Matkin, Craig, Jeffries, Steven J., Noren, Dawn P., Kaplan, Isaac C., Scordino, Jonathan J., and Hanson, M. Bradley
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...

An Evaluation of Collaborative Salmon Fishery Management in Prince William Sound, Alaska

Creator:: Sheridan, Thomas M.
Abstract:: Collaborative decision-making is often promoted as a means to achieve socially acceptable and enduring solutions to natural resource management issues, and one that holds promise for resolving “wicked” problems. However, success rates for implementation of collaborative recommendations are unknown. This paper explores challenges to collaborative salmon fishery management in Prince...

Headwater Streams and Wetlands are Critical for Sustaining Fish, Fisheries, and Ecosystem Services

Creator:: Colvin, Susan A. R., Sullivan, S. Mazeika P., Shirey, Patrick D., Colvin, Randall W., Winemiller, Kirk O., Hughes, Robert M., Fausch, Kurt D., Infante, Dana M., Olden, Julian D., Bestgen, Kevin R., Danehy, Robert J., and Eby, Lisa
Abstract:: Headwater streams and wetlands are integral components of watersheds that are critical for biodiversity, fisheries, ecosystem functions, natural resource-based economies, and human society and culture. These and other ecosystem services provided by intact and clean headwater streams and wetlands are critical for a sustainable future. Loss of legal protections for...

Discursive and Psychological Processes in Project MATCH Treatment Manuals and 12-Step Program Literature

Creator:: O'Hara, Margaret A.
Abstract:: Addiction is a word that represents a condition that, at best, causes minor disruptions to one’s life and, at worst, is lethal. The current definition was developed by 80 neuroscientists. It references substance use and other behaviors and includes food and sex. Addictions do not seem to be lessening but...

Mechanistic analysis of the wave-current interaction in the plume region of a partially mixed tidal inlet

Creator:: Moghimi, Saeed, Özkan-Haller, H. Tuba, Akan, Cigdem, and Jurisa, Joseph T.
Abstract:: In this research, a three-dimensional coupled wave-circulation model, including meteorological forcing, freshwater inflow and time varying open boundary conditions, for New River Inlet is validated. A mechanistic approach is taken to investigate how various wave-current interaction mechanisms affect the nearshore circulation, plume expansion and surface wave field in the plume...

Local and regional stressors interact to drive a salinization-induced outbreak of predators on oyster reefs

Creator:: Kimbro, David L., White, J. Wilson, Tillotson, Hanna, Cox, Nikkie, Christopher, Megan, Stokes-Cawley, Owen, Yuan, Samantha, Pusack, Timothy J., and Stallings, Christopher D.
Abstract:: Predator outbreaks are predicted to increasingly decimate economically and ecologically important prey populations because global climate change and food-web modifications frequently facilitate predators and stress prey. Natural systems are organized hierarchically, with processes operating at multiple scales giving rise to patterns of biodiversity, so predicting and managing outbreaks requires a...

River Restoration to Achieve a Stage 0 Condition: Summary of a Workshop Held November 5-6, 2020

Creator:: Behan, Jeff, Fetcho, K., Davis, R., and Gaines, L.
Abstract:: Restoration to achieve Stage 0 is a valley-scale, process-based (hydrologic, geologic and biological) approach that aims to reestablish stream depositional environments to maximize longitudinal, lateral, and vertical connectivity at base flows and facilitate development of dynamic, self-formed and self-sustaining wetland-stream complexes. The term Stage 0 originally described complex multi-channel conditions...
