Seasonal and interannual variation in juvenile salmonids and associated fish assemblage in open waters of the lower Columbia River estuary

Creator:: Weitkamp, Laurie A., Bentley, Paul J., and Litz, Marisa N. C.
Abstract:: The transition between freshwater and marine environments is associated with high mortality for juvenile anadromous salmonids, yet little is known about this critical period in many large rivers. To address this deficiency, we investigated the estuarine ecology of juvenile salmonids and their associated fish assemblage in open-water habitats of the...

Fish Misidentification and Potential Implications to Monitoring Within the San Francisco Estuary, California

Creator:: Kirsch, Joseph E., Day, Julie L., Peterson, James T., and Fullerton, David K.
Abstract:: Fish monitoring programs often rely on the collection, species identification, and counting of individual fish over time to inform natural resource management decisions. Thus, the utility of the data used to inform these decisions can be negatively affected by species misidentification. Fish species misidentification bias can be minimized by confirming...

The effects of changing climate on estuarine water levels: a United States Pacific Northwest case study

Creator:: Parker, Kai, Hill, David, García-Medina, Gabriel, and Beamer, Jordan
Abstract:: Climate change impacts on extreme water levels (WLs) at two United States Pacific Northwest estuaries are investigated using a multicomponent process-based modeling framework. The integrated impact of climate change on estuarine forcing is considered using a series of sub-models that track changes to oceanic, atmospheric, and hydrologic controls on hydrodynamics....

Transdisciplinary Research in Water Sustainability: What’s in it for an Engaged Researcher-Stakeholder Community?

Creator:: Chan, Samuel, Ferguson, Laura, Santelmann, Mary V., and Tilt, Bryan
Abstract:: This study uses semi-structured interviews and an online survey to explore the structure, challenges and outcomes of a five-year National Science Foundation-funded water scarcity modelling project in the Willamette River Basin of Oregon, USA. The research team chose to facilitate broader impacts by engaging stakeholders from the study’s inception (e.g....

Resource Selection by the California Condor (Gymnogyps californianus) Relative to Terrestrial-Based Habitats and Meteorological Conditions

Creator:: Rivers, James W., Johnson, J. Matthew, Haig, Susan M., Schwarz, Carl J., Glendening, John W., Burnett, L. Joseph, George, Daniel, and Grantham, Jesse
Abstract:: Condors and vultures are distinct from most other terrestrial birds because they use extensive soaring flight for their daily movements. Therefore, assessing resource selection by these avian scavengers requires quantifying the availability of terrestrial-based habitats, as well as meteorological variables that influence atmospheric conditions necessary for soaring. In this study,...

Abundance, movements, and feeding habits of harbor seals, Phoca vitulina, at Netarts and Tillamook Bays, Oregon

Creator:: Brown, Robin F. and Mate, Bruce R.
Abstract:: Patterns of seasonal abundance of harbor seals at Netarts and Tillamook Bays, Oregon, were documented by recording numbers of seals hauling out on tidally exposed sand flats in both bays. Harbor seal abundance at Tillamook Bay peaked during pupping (May-June) and molting (August) periods, while peak abundance at Netarts Bay...

Trends in Developed Land Cover Adjacent to Habitat for Threatened Salmon in Puget Sound, Washington, U.S.A.

Creator:: Bartz, Krista K., Ford, Michael J., Beechie, Timothy J., Fresh, Kurt L., Pess, George R., Kennedy, Robert E., Rowse, Melinda L., and Sheer, Mindi
Abstract:: For widely distributed species at risk, such as Pacific salmon (Oncorhynchus spp.), habitat monitoring is both essential and challenging. Only recently have widespread monitoring programs been implemented for salmon habitat in the Pacific Northwest. Remote sensing data, such as Landsat images, are therefore a useful way to evaluate trends prior...

Migratory Patterns of Wild Chinook Salmon Oncorhynchus tshawytscha Returning to a Large, Free-Flowing River Basin

Creator:: Eiler, John H., Evans, Allison N., and Schreck, Carl B.
Abstract:: Upriver movements were determined for Chinook salmon Oncorhynchus tshawytscha returning to the Yukon River, a large, virtually pristine river basin. These returns have declined dramatically since the late 1990s, and information is needed to better manage the run and facilitate conservation efforts. A total of 2,860 fish were radio tagged...

Greater sage-grouse apparent nest productivity and chick survival in Carbon County, Wyoming

Creator:: Kehmeier, Jon W., Hansen, Christopher P., Schreiber, Leslie A., Thompson, Frank R., III, Rumble, Mark A., Wojik, Nate, Millspaugh, Joshua J., and Gamo, R. Scott
Abstract:: Greater sage-grouse Centrocercus urophasianus populations across North America have been declining due to degradation and fragmentation of sagebrush habitat. As part of a study quantifying greater sage-grouse demographics prior to construction of a wind energy facility, we estimated apparent net nest productivity and survival rate of chicks associated with radio-equipped...

Ocean distribution of the American shad (Alosa sapidissima) along the Pacific coast of North America

Creator:: Pearcy, William G. and Fisher, Joseph P.
Abstract:: We examined the incidental catches of American shad (Alosa sapidissima) taken during research cruises and in commercial and recreational landings along the Pacific coast of North America during over 30 years of sampling. Shad, an introduced species, was mainly found over the shallow continental shelf, and largest catches and highest...
