Salt marsh reestablishment following dike breaching in the Salmon River estuary, Oregon

Creator:: Mitchell, Diane Lynne
Abstract:: A 22 ha, 1S yeas old, diked permanent pasture in the Salmon River estuary in Lincoln County, Oregon, was chosen for a study to determine the potential for natural salt marsh restoration with dike breaching. Two undiked fragments of relatively undisturbed salt marsh, one at each end of the study...

The distribution of intertidal diatoms associated with the sediments of Yaquina Estuary, Oregon

Creator:: Amspoker, Michael C.
Abstract:: Sediment samples were collected from eight sampling sites along the Yaquina Estuary, Oregon from Yaquina Bay to Elk City near the head of the estuary. Samples were collected in November 1973, February 1974, May 1974 and August 1974 from two or three intertidal levels depending on the magnitude of the...

The distribution of epiphytic diatoms in Yaquina Estuary, Oregon

Creator:: Main, Stephen Paul
Abstract:: Epiphytic diatom assemblages in the intertidal zone of Yaquina Bay and estuary were obtained from the following host macrophytes: Zostera marina, Fucus evanescens, and species of Enteromorpha, Polysiphonia, and Ulva. Samples were collected in September 1970 and in January and May 1971 from seven stations approximately evenly spaced between the...

Salinity as a factor controlling the distribution of benthic estuarine diatoms

Creator:: Martin, John Varick
Abstract:: A two phase investigation was undertaken in an attempt to determine the effects of variations in salinity on the distribution of benthic estuarine diatoms. The estuary studied was that of the Yaquina River which originates in the Coast Range of western Oregon and discharges into the Pacific Ocean at the...

Investigating Demographic and Evolutionary Factors Important for Fish Reintroduction

Creator:: Sard, Nicholas M.
Abstract:: Reintroduction programs are used to re-establish species back into their historical habitat. Most reintroduction programs have failed and few papers have evaluated factors that may be important to Pacific salmon. The 158 meter tall Cougar Dam has blocked Chinook salmon (Oncorhynchus tshawytscha) from accessing 40 kilometers of historical spawning and...

Relationships among juvenile anadromous salmonids, their freshwater habitat, and landscape characteristics over multiple years and spatial scales in the Elk River, Oregon

Creator:: Burnett, Kelly M.
Abstract:: Research on the distribution of juvenile salmonids in streams has been dominated by studies examining small areas over short periods. However, information relevant to freshwater influences on population persistence is likely to derive from longer-term, multi-scale studies. Relationships were examined among juvenile anadromous salmonids, their freshwater habitat, and landscape characteristics...

Beyond the paired-catchment approach : isotope tracing to illuminate stocks, flows, transit time, and scaling

Creator:: Hale, V. Cody
Abstract:: This dissertation integrates a process-based hydrological investigation with an ongoing paired-catchment study to better understand how forest harvest impacts catchment function at multiple scales. We do this by addressing fundamental questions related to the stocks, flows and transit times of water. Isotope tracers are used within a top-down catchment intercomparison...

How the animals found their places : pattern detection, experimentation, and epistemology in a high desert stream fish assemblage

Creator:: White, Seth Michael
Abstract:: I examined the relative roles of biotic and abiotic factors in structuring redband trout Oncorhynchus mykiss distributions in the South Fork John Day. I first examined the relationship between the biological traits of the fish assemblage and riparian-geomorphic features in context of prevailing theories of stream ecology stemming from the...

Social Learning and Adaptive Capacity in Collaborative Watershed Partnerships

Creator:: Calvert, Daniel T.
Abstract:: This dissertation examines learning driven adaptations in salmon recovery efforts and water resources management in Oregon. The case study utilizes a framework highlighting the connections between human and natural systems. Semi-structured interviews are used to analyze interactions between rural riparian landowners and watershed council staffs living and working in Oregon’s...
