Defining micro-habitat relationships for juvenile black rockfish, Sebastes melanops

Creator:: Mann, Marion E.
Abstract:: The functioning of marine habitats needs to be understood in the context of the ecological relationships and associations between organisms and the physical and biogenic environment they inhabit. Thus, it becomes important to explore and define habitat features which contribute to these relationships and which are important in the life...

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...

Life histories of juvenile Chinook salmon (Oncorhynchus tshawytscha) in the Columbia River estuary as inferred from scale and otolith microchemistry

Creator:: Campbell, Lance A.
Abstract:: Despite evidence that juvenile Chinook salmon (Oncorhynchus tshawytscha) utilize North Pacific estuaries for growth and salinity acclimation, research in the Columbia River estuary has lead to opposing hypotheses about the estuary’s importance as a salmon rearing environment. Many contemporary tagging studies indicate that salmon residency within the estuary is short...

Floodplain emergent wetlands as rearing habitat for fishes and the implications for wetland enhancement

Creator:: Henning, Julie A.
Abstract:: Seasonal emergent wetlands in the Pacific Northwest have not been regarded traditionally as fish rearing habitat, despite access to such habitat when river flows overtop riverbanks and connect to the floodplain. As a result, restoration and enhancement projects to remediate for the loss of such wetland habitat are being implemented...

Growth, residence, and movement of juvenile Chinook salmon within restored and reference estuarine marsh channels in Salmon River, Oregon

Creator:: Hering, David K.
Abstract:: Tidal wetland channels provide rearing habitat for juvenile Chinook salmon as they emigrate from freshwater habitat and prepare to enter the ocean. Widespread diking and drainage of estuarine marshes for agricultural and urban development may have contributed to a decline in salmon abundance in the Pacific Northwest, prompting efforts to...

Habitat use, movement, and life history variation of coastal cutthroat trout, Oncorhynchus clarkii clarkii, in the Salmon River estuary, Oregon

Creator:: Krentz, Lisa K.
Abstract:: Anadromous coastal cutthroat trout Oncorhynchus clarkii clarkii may be highly dependent on estuaries, passing through them multiple times during their lifetime. However, few studies have investigated estuarine use by coastal cutthroat trout and it is often thought that estuaries serve primarily as migration corridors rather than rearing areas. We used...

Fleming, Ronald A.zip

Creator:: Fleming, Ronald A.
Abstract:: Non-point agricultural contaminants, such as nitrogen, may lower groundwater quality and thereby impose health and environmental risks. The objective of this study is to evaluate tax policies to control agricultural pollutants in a spatially heterogeneous and dynamic setting. The focus of the study is non-point source nitrate contamination of groundwater...

Physiological ecology of juvenile Chinook salmon (Oncorhynchus tshawytscha) rearing in fluctuating salinity environments

Creator:: Hackmann, Crystal R.
Abstract:: Estuaries provide juvenile salmonids with highly productive feeding grounds, refugia from tidal fluctuations and predators, and acclimation areas for smoltification. However, these dynamic, fluctuating salinity environments may also be physiologically stressful to growing juvenile fish. In order to evaluate the costs and benefits of estuarine marshes to juvenile Chinook salmon,...

Molecular and cellular mechanisms of aromatic hydrocarbon axonopathy

Creator:: Kim, Min-Sun
Abstract:: Hydrocarbon solvents are widely used in the production of paints, adhesives, dyes, polymers, plastics, textiles, printing inks, agricultural products and pharmaceuticals. While the neuropathic potential of aliphatic solvents was shown in the 1970s, little is known about the neuropathic potential of aromatic solvents. The present study examines such solvents, 1,2-diethylbenzene...

Juvenile Salmonid Use of Freshwater Emergent Wetlands in the Floodplain and Its Implications for Conservation Management

Creator:: Henning, Julie A., Gresswell, Robert E., and Fleming, Ian A.
Abstract:: A recent trend of enhancing freshwater emergent wetlands for waterfowl and other wildlife has raised concern about the effects of such measures on juvenile salmonids. We undertook this study to quantify the degree and extent of juvenile Pacific salmon Oncorhynchus spp. utilization of enhanced and unenhanced emergent wetlands within the...
