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...

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...

Indicators for Monitoring Biological Integrity of Inland, Freshwater Wetlands : A Survey of North American Technical Literature (1990-2000)

Creator:: Adamus, Paul R.
Abstract:: Potentially relevant literature for the years 1990-1999 was identified by (a) conducting keyword searches of computerized bibliographic databases, especially CAB Abstracts and Aquatic Sciences and Fisheries Abstracts, (b) reading through the tables of contents of a few especially relevant journals, (c) searching the internet for pertinent bibliographies, and (d) to...

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...

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...

Vegetation characterization of three contrasting riparian areas : Williamette Valley, Oregon

Creator:: McAllister, Lynne S., Dwire, Kathleen A., and Griffith, Stephen M.
Abstract:: Much of the native riparian vegetation of the Willamette Valley, Oregon, has been replaced with agricultural crops or invasive non-native plant species. Detailed information about current Willamette Valley riparian vegetation is generally lacking. Plant specie composition data are useful in a variety of applications, including condition assessment, environmental monitoring and...
