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...
Resource Type:: Technical Report

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...

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...

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...

Creator:: Moser, Thomas J., Lindeman, Dale R., Wigington, P.J., Schuft, Michael, and Van Sickle, John
Abstract:: This paper describes the application of aerial photography and GIS technology to develop flexible and transferable methods for multi-spatial scale characterization and analysis of riparian corridors. Relationships between structural attributes of riparian corridors and indicators of stream ecological conditions are not well established. As part of a research project focused...

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...
