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...

Comparison of submersible-survey and hydroacoustic-survey estimates of fish density on a rocky bank

Creator:: Starr, Richard M., Fox, David S., Hixon, Mark Anthony, Tissot, Brian N., Johnson, Gary E., and Barss, William H.
Abstract:: Submersible belt-transect surveys along a rocky bottom were combined with acoustic surveys of the water column to estimate depth distribution and density of fishes at Stonewall Bank, Oregon in the northeastern Pacific Ocean from September through October 1991. The objectives of the study were to determine the proportion of fish...

Reconciling estimates of the contemporary North American carbon balance among terrestrial biosphere models, atmospheric inversions, and a new approach for estimating net ecosystem exchange from inventory-based data

Creator:: Hayes, Daniel J., Turner, David P., Stinson, Graham, McGuire, A. David, Wei, Yaxing, West, Tristram O., Heath, Linda S., de Jong, Bernardus, McConkey, Brian G., Birdsey, Richard A., Kurz, Werner A., Jacobson, Andrew R., Huntzinger, Deborah N., Pan, Yude, Post, W. Mac, and Cook, Robert B.
Abstract:: We develop an approach for estimating net ecosystem exchange (NEE) using inventory-based information over North America (NA) for a recent 7-year period (ca. 2000–2006). The approach notably retains information on the spatial distribution of NEE, or the vertical exchange between land and atmosphere of all non-fossil fuel sources and sinks...

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...

Persistence of Triploid Grass Carp in Devils Lake, Oregon

Creator:: Clemens, Benjamin J., Spangler, John J., Robertson, Paul L., Galovich, Gary M., Banner, Craig R., Gunckel, Stephanie L., Ketchum, Lindsay L., Bowden, R. Kanani, Spagnoli, Sean T., Kent, Michael L., and Kirk, James P.
Abstract:: Grass carp Ctenopharyngodon idella are sometimes used as a biological tool for managing aquatic vegetation in reservoirs. Sterile, triploid fish were stocked in Devils Lake, Oregon, during 1986, 1987, and 1993 to control aquatic vegetation. We present a case study for using multiple measures on the same fish to determine...

Fish-habitat associations on a deep reef at the edge of the Oregon continental shelf

Creator:: Tissot, Brian N., Hixon, Mark Anthony, Barss, William, and Stein, David L.
Abstract:: Heceta Bank is a large reef on the edge of the central Oregon continental shelf that supports a wide variety of commercial fisheries. Using the research submersible Delta, we studied fish abundances on Heceta Bank and the relationship between species composition of fish assemblages and bottom types. Cluster analysis indicated...

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...

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...

Tertiary geologic framework, neotectonics, and petroleum potential of the Oregon-Washington Continental Margin

Creator:: Snavely, P. D., Jr. and Geological Survey (U.S.)
Abstract:: The Tertiary geologic evolution of the Oregon and Washington continental margin was molded by episodic periods of convergence between the Pacific oceanic plates and the North American plate. This margin is the site of a deep basin that is floored by Paleocene to lower Eocene oceanic crust and contains more...

Greater Sage-Grouse Umbrella CCAA for Wyoming Ranch Management: a Candidate Conservation Agreement with Assurances for Greater Sage-Grouse Centrocercus urophasianus

Creator:: Wyoming Governor’s Office, Wyoming Bureau of Land Management, Natural Resources Conservation Service, Wyoming Game and Fish Department, Wyoming Department of Agriculture, Wyoming Association of Conservation Districts, United States. Forest Service, and United States. Fish and Wildlife Service
Abstract:: Prior to settlement in the 19th century, greater sage-grouse (Centrocercus urophasianus; hereafter referred to as ‘sage-grouse’) inhabited 13 western States and three Canadian provinces, and their potential habitat covered over 1,200,483 square kilometers (km) (463,509 square miles (mi)). Sage-grouse have declined across their range due to a variety of causes...
