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...

The role of predation by the red rock crab, Cancer productus, on the invasive European green crab, Carcinus maenas, in Yaquina Bay, Oregon

Creator:: Hunt, Christopher Erik
Abstract:: In Yaquina Bay, Oregon, I observed very little overlap in the distribution of the invasive green crab, Carcinus maenas, and the larger red rock crab, Cancer productus. Red rock crabs dominate the more saline, cooler lower estuary and green crabs, the less saline, warmer upper estuary. Because caged green crabs...

Yaquina Bay and South Beach Marina sediment sampling evaluation

Creator:: United States. Army. Corps of Engineers. Portland District
Abstract:: "Nine (9) sediment samples and 1 QC duplicate were collected from Yaquina Bay and South Beach Marina (see Figures 1) on May 31, 2000. All samples were submitted for physical analyses, with 4 samples analyzed for metals (9 inorganic), total organic carbon (TOC), pesticides/polychlorinated biphenyls (PCBs), phenols, phthalates, miscellaneous extractables,polynuclear...

Source identification of fecal pollution in the Tillamook watershed : antibiotic discriminant analysis

Creator:: Bower, Robert J.
Abstract:: The identification of sources of point and nonpoint fecal pollution is difficult to determine. Understanding the sources of fecal organisms in quality limited waters could greatly enhance our ability to restore and protect the water quality and habitat of these systems. Antibiotic resistance patterns of fecal streptococci bacteria were analyzed...

Re‐establishment of the native oyster, Ostrea conchaphila, in Netarts Bay, Oregon, USA

Creator:: Archer, Pamela Emily
Abstract:: Olympia oysters, “Ostrea conchaphila,” were once common along the west coast of North America. A popular delicacy, native oyster populations began to decline in the late 1800’s due to over‐harvest, degraded water quality, and habitat loss. Interest in re‐establishing the native oyster in a small Oregon estuary, Netarts Bay, culminated...

Sediment accumulation and human impacts in Tillamook Bay, Oregon

Creator:: Styllas, Michael N.
Abstract:: Tillamook Bay is the second largest estuary on the Oregon coast, and concerns have been raised whether human induced impacts have been responsible for the perceived increase in sedimentation rates during the past century. Major land-use practices within the five watersheds of the Bay include logging, forest fires, the construction...
