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...

Ungulate activity classification : calibrating activity monitor GPS collars for Rocky Mountain elk, mule deer, and cattle

Creator:: Gaylord, Adam J.
Abstract:: Ungulate behavior has been studied extensively but direct observation of free-ranging animals over long periods of time and large geographic areas is often prohibitively difficult. Improved technology, such as GPS collars fitted with motion-sensitive activity monitors, provides researchers with a potential tool to remotely collect fine scale activity and location...

Value of Prior and Novel Information in Managing a Mixed-Stock Recreational Chinook Salmon Fishery

Creator:: Jensen, Alexander J.
Abstract:: Many economically important Pacific salmon fisheries along the west coast of North America are mixed-stock, recreational systems, in which managers strive to account for interactions between fish, anglers, and management policy while balancing fishery access against conservation of vulnerable stocks. Specific challenges facing fisheries managers include limited control over angling...

Local Variability Mediates Vulnerability of Trout Populations to Land Use and Climate Change

Creator:: Penaluna, Brooke E., Dunham, Jason B., Railsback, Steve F., Arismendi, Ivan, Johnson, Sherri L., Bilby, Robert E., Safeeq, Mohammad, and Skaugset, Arne E.
Abstract:: Land use and climate change occur simultaneously around the globe. Fully understanding their separate and combined effects requires a mechanistic understanding at the local scale where their effects are ultimately realized. Here we applied an individual-based model of fish population dynamics to evaluate the role of local stream variability in...

Submersible observations of deep-reef fishes of Heceta Bank, Oregon

Creator:: Pearcy, William G., Stein, David L., Hixon, Mark Anthony, Pikitch, Ellen K., Barss, William H., and Starr, Richard M.
Abstract:: Rockfishes, Sebastes spp.. were the most numerous and speciose fishes seen during 16 submersible dives from 64 to 305 m depth in the vicinity of Heceta Bank off the coast of Oregon. Dense schools of juvenile rockfishes and large yellowtail rockfish, S. flavidus, were observed only over rocky, high relief...
