Life-history organization of herring (Clupea harengus pallasi) in the northeast Pacific

Creator:: Aleaziz, Farzad
Abstract:: The distribution of herring (Clupea harengus pallasi) in the Northeast Pacific extends from southern California to northern Alaska. Studies on variation in herring life-history are limited to local characteristics and recruitment populations or relatively restricted regions of the Northeast Pacific. In this study I assessed herring life-history patterns and recruitment...

Bacteriophages Significantly Reduce Mortality of Larval Pacific Oysters Crassostrea gigas from Infection by the Pathogenic Bacterium Vibrio coralliilyticus RE98

Creator:: Madison, David B.
Abstract:: Vibrio coralliilyticus (Vcor) is a bacterial pathogen that is well adapted to shellfish hatcheries and is very pathogenic to the larvae of the Pacific oyster Crassostrea gigas. Vcor has been associated with several large scale larval mortality events in the Pacific Northwest that interrupt the supply of seed oysters available...

Bottom-up Drivers of Primary Producers and Predator Populations in Oregon Streams

Creator:: Kaylor, Matthew J.
Abstract:: Humans have drastically altered the physical habitat and food web structure of stream ecosystems. Two major impacts humans have had on Pacific Northwest streams are modification of streamside forests (as a result of agriculture, land development, and timber harvest), and declines in the return of wild anadromous salmon to headwater...

Life-history organization of cutthroat trout in Yellowstone Lake and its management implications

Creator:: Gresswell, Robert E.
Abstract:: Life-history organization of the cutthroat trout (Oncorhvnchus clarki) may be viewed at various levels, including species, subspecies, metapopulation, population, or individual. Each level varies in spatial scale and temporal persistence, and components at each level continually change with changes in environment. Cutthroat trout are widely distributed throughout the western USA,...

Temperature-modulated 7,12-dimethylbenz(a)antheracene carcinogenicity in rainbow trout

Creator:: Zahr, Camille Reda
Abstract:: Temperature influences the incidence of chemically induced cancer in fish, with warmer temperatures being associated with higher cancer incidence. The mechanisms of temperature-modulated chemical carcinogenesis in fish, however, have not been described in detail. Therefore, one primary objective of this study was increased understanding of how temperature-modulated genotoxicity of 7,12-...

Distribution of juvenile salmonids and stream habitat relative to 15-year-old debris-flow deposits in the Oregon Coast Range

Creator:: Kirkby, Kristen-Marie S.
Abstract:: Debris flows, common disturbances in many mountainous areas, initially scour or bury stream habitats; however, debris flows deliver vast amounts of wood, boulders, and gravel that may ultimately form complex stream habitat to potentially support a diverse salmonid assemblage. The materials deposited by debris flows would otherwise be inaccessible to...

Distribution and life history of the spiny dogfish (Squalus acanthias) off the Oregon and Washington coasts

Creator:: Richards, Jaclyn M.
Abstract:: This study examines the spatial and temporal distribution and life history of the "offshore" component of the Northeastern Pacific spiny dogfish (Squalus acanthias) population. Distribution was examined in relation to latitude, depth, the Columbia River plume and large-scale climate changes. Fishery and survey data indicate that the Northeastern Pacific spiny...

Is the past present? Historical splash-dam mapping and stream disturbance detection in the Oregon Coastal Province

Creator:: Miller, Rebecca R.
Abstract:: Severe scouring from splash damming was one of the earliest reported forms of widespread anthropogenic disturbance in streams of the Pacific Northwest, USA. Splash damming was a common method of log transport in western Oregon from the 1880s through the 1950s. Before being released in large freshets to downstream lumber...

Responses of a threatened cutthroat trout to an introduced, invading salmonid : ecological implications for growth, stress, and behavior

Creator:: Osborne-Gowey, Jeremiah D.
Abstract:: Recent studies suggest that competition from brook trout (Salvelinus fontinalis; EBT) may have negative effects (e.g. displacement) on Lahontan cutthroat trout (Oncorhynchus clarki henshawi; LCT). Results from these studies have failed to elucidate the responsible mechanisms and have not examined if changing environmental conditions result in competitive/subordinate role reversals. The...

A Contingency-Based Evaluation for Beaver Restoration of Salmon Habitat in Oregon Coastal Streams

Creator:: Stevenson, John R.
Abstract:: Streams across the western United States are impaired from human alterations that have reduced freshwater habitat by simplifying channel complexity and disconnecting floodplains (Knox et al., 2022; Waples et al., 2008; Wohl, 2014). Climate change is likely to continue exacerbating these risks by warming summer surface stream temperatures (Crozier et...
