Biostratigraphy and paleoecology of the Coaledo and Bastendorff Formations, southwestern Oregon

Creator:: Rooth, Guy Harlan
Abstract:: Fossil foraminifers from the Coaledo and Bastendorff Formations near Coos Bay in southwestern Oregon were studied in an attempt to determine the age and environment of deposition. Fresh unweathered samples were collected from sea cliffs between Cape Arago and Charleston, Oregon. A large late Eocene delta is preserved in the...

Plant communities and elevation in the diked portion of Joe Ney Slough : a baseline assessment of a marsh restoration project in Coos Bay, Oregon

Creator:: Taylor, Alan H.
Abstract:: The need to preserve Oregon's estuaries has been expressed through the Land Conservation and Development Commission's Estuarine Resources Goal 16. The first use of the mitigation guideline set forth in this goal is in the Coos Bay estuary. The proposed North Bend Airport runway extension will fill 32 acres (13...

Juvenile Coho Salmon (Oncorhynchus kisutch) Diet in Brackish and Freshwater Habitats in the Stream-estuary Ecotones of Coos Bay, Oregon

Creator:: Mackereth, Kailan F.
Abstract:: Loss of lowland estuarine and freshwater off-channel habitats along the Pacific Northwest coast has contributed to the decline of salmonid populations. These habitats serve as nursery grounds for juvenile salmonids providing them with food, winter shelter, and a transition zone between freshwater and saltwater. Lowland areas have undergone anthropogenic alterations...

Juvenile coho salmon movement and migration through tide gates

Creator:: Bass, Arthur
Abstract:: Tidal marshlands in the upper estuary ecotone provide essential habitat for juvenile salmonids. In this environment, salmonids grow rapidly and acclimate to saltwater. Worldwide, tidal marshes have been diked and drained to provide agricultural and residential land. Tide gates are one-way doors integrated into dike systems that prevent saltwater flooding...

Identifying potential wetland restoration sites for estuary-wide restoration planning in Oregon : A pilot project in the Coos Estuary

Creator:: Fuss, J. David
Abstract:: Oregon's estuaries have been significantly altered by human activity, so that many former tidal wetlands no longer provide the functions, such as fish and wildlife habitat, erosion protection from storms, and water quality maintenance, that preserve the integrity of estuarine ecosystems. Oregon has been a leader in wetland protection and...

Forestry & Communication : A Coos Bay Case Study

Creator:: Livingstone, Tasha
Abstract:: This thesis combines elements of forestry, interpersonal communication, and rhetoric to describe where residents of Coos Bay and North Bend Oregon obtain information about forests and forest uses, and how they view the credibility of that information. As a qualitative exploratory study, grounded theory methodology was used to develop theme...

Conservation of Oenothera wolfii (Onagraceae) : introducing a threatened plant into two protected locations in Oregon

Creator:: Currin, Rebecca E.
Abstract:: The showy biennial to short-lived perennial Oenothera wolfii (Munz) Raven, Dietrich & Stubbe (Wolf’s evening primrose) occurs in only a small number of isolated populations on the southern Oregon and northern California coast. This rare species is currently listed as Threatened in Oregon, and is considered a Species of Concern...

A seasonal study of sediment reworking by Neotrypaea californiensis in Yaquina Bay, Oregon

Creator:: Fritz, Cara E.
Abstract:: A year-long field study was undertaken to investigate the influence of a number of physical and biological factors, specifically temperature, organic carbon content, and shrimp population dynamics on sediment reworking rates by the ghost shrimp Neotrypaea calforniensis. Because of its role as a structuring agent in estuaries along the West...

Movement and abundance of lingcod (Ophiodon elongatus) in Yaquina Bay Estuary, Oregon: evidence for essential habitat designation

Creator:: Schwager, Tad W.
Abstract:: Lingcod (Ophiodon elongatus) are known to utilize certain estuaries along the Pacific coast of the United States, but the importance of these habitats to the coast-wide population is not well understood. In this study, general patterns of estuarine habitat use were assessed by tracking the movement of sub-adult and adult...

Habitat associations and determinants of refuge use in post-settlement lingcod (Ophiodon elongatus)

Creator:: Petrie, Megan E.
Abstract:: Lingcod are an overexploited fish species in the Pacific Northwest and although there has been extensive study of the habitat requirements of adults, particularly during spawning, relatively little is known regarding the habitat requirements of post-settlement juveniles. Many juvenile fish use structural components of habitat to alleviate the risk of...
