Heirarachial framework for conserving biodiversity

Creator:: White, Denis, Preston, Eric, Freemark, Kathryn, Kiester, Ross, and Corvallis Environmental Research Laboratory
Abstract:: Corvallis scientists report on a multi-organization study that looked at biodiversity as a two stage problem. The first stage is finding those places over a region of study that have the greatest combined biodiversity, and the second stage is studying those important places to see what effects changes in land...

Marine wetland boundary definition : evaluation of methodology

Creator:: Eilers, H. Peter, Taylor, Alan, Sanville, William, and Corvallis Environmental Research Laboratory
Abstract:: With legislation to protect wetlands and current pressures to convert them to other uses, it is often necessary to accurately determine a wetland-upland boundary. We investigated 6 methods to establish such a boundary based on vegetation. Each method was applied to a common data set obtained from 295 quadrats along...

Physical and chemical characteristics of the Yaquina Estuary, Oregon

Creator:: Callaway, R. J., Specht, David T., and National Health and Environmental Effects Research Laboratory (U.S.). Western Ecology Division. Coastal Ecology Branch
Abstract:: "After a brief description of the setting of the Yaquina Estuary, estuarine dynamics and classification, and estuarine chemistry are presented. Then, temperature-salinity relations are reviewed using the Rattray-Officer model in simulating variable distributions reported by Callaway and Specht (1982) and Callaway (1991). Finally, the numerical models DynHyd and WASP are...

Physical and chemical characteristics of the Yaquina Estuary, Oregon

Creator:: Callaway, Richard J. and Specht, David T.
Abstract:: This report discusses data collected in the Yaquina Estuary from July 1976 through December 1977 at 6-8 week intervals. Also summarized are recording salinometer, runoff and precipitation data from September 1967 through July 1968. Station names and locations for the 76-77 field data are shown in Figure 1. Figure 2...

Flushing study of South Beach Marina, Oregon

Creator:: Callaway, Richard J. and U.S. Environmental Protection Agency. Corvallis Environmental Research Laboratory
Abstract:: "This report concerns one aspect of the marina permit evaluation process: water quality impacts related to marina circulation and flushing efficiency. These physical properties vary with the wind, tide range, water density and physical dimensions of a marina. Water quality is affected by the degree of flushing, and sediment redistribution...

Monitoring design for riparian forests in the Pacific Northwest : research plan

Creator:: Ringold, Paul L., Barker, Jerry R., Bollman, Mike, Bradshaw, Gay, Carson, Ward, Cline, Steven Paul, Fiorella, Maria R., Stepp, Jennifer, United States. Environmental Protection Agency. Office of Research and Development, National Health and Environmental Effects Laboratory, Dynamac Corporation, Oregon State University, and United States. Forest Service
Abstract:: The goal of this project is to recommend a broadly-acceptale efficient and effective methodology for characterizing streamside riparian attributes in forested settings at the site grain for regional monitoring. The authors consider monitoring design in the context of three interacting constraints: ecological functions, capabilities of technologies, and user needs. The...

Response of estuarine diatom assemblages to ultraviolet-B radiation (290-320 nm)

Creator:: Brooker, Deborah L., Worrest, Robert C.,, and Oregon State University
Abstract:: Artificial substrates colonized by diatoms from Yaquina Estuary, Oregon, were exposed to solar visible radiation and three levels of ultraviolet radiation (UV-B, 290-320 nm). Flow-through microcosms were constructed inside a glasshouse to serve as chambers for the artificial substrates. The artificial substrates were sampled during three spring/summer experiments. Chlorophyll a...
