Response of a small Oregon estuary to coseismic subsidence and postseismic uplift in the past 300 years
H.M. Kelsey, Robert C. Witter, E. Hemphill-Haley
1998, Geology (26) 231-234
The Sixes River estuary, south coastal Oregon, sits above the locked portion of the Cascadia subduction zone, which intermittently releases in subduction-zone earthquakes. One such Cascadia earthquake ∼300 years ago caused subsidence and a tsunami at the Sixes estuary. The subsidence raised the...

Molecular approaches to fish vaccines
J. R. Winton
1998, Journal of Applied Ichthyology (14) 153-158
For more than 50 years, researchers have tested a variety of killed, attenuated, and subunit preparations for control offish diseases. The earliest fish vaccines used killed preparations containing whole bacteria, viruses, or parasites and today, several bacterins have become commercially successful with more expected as improved delivery systems and adjuvants...

Evaluating landscape health: Integrating societal goals and biophysical process
D.J. Rapport, C. Gaudet, J.R. Karr, Jill Baron, C. Bohlen, W. Jackson, Bruce Jones, R.J. Naiman, B. Norton, M. M. Pollock
1998, Journal of Environmental Management (53) 1-15
Evaluating landscape change requires the integration of the social and natural sciences. The social sciences contribute to articulating societal values that govern landscape change, while the natural sciences contribute to understanding the biophysical processes that are influenced by human activity and result in ecological change. Building upon Aldo Leopold's criteria...
Indirect measurement of Delta outflow using ultrasonic velocity meters and comparison with mass-balance calculated outflow
Richard N. Oltmann
1998, Interagency Ecological Program Newsletter (11) 5-8
A measurement of the quantity of water flowing from the Sacramento-San Joaquin Delta into Suisun Bay (Delta outflow) has been desired by those studying and managing the San Francisco Bay/Delta estuary since the 1920s. Historically, Delta outflow has been estimated using a mass-balance calculation that uses measured Delta inflows and...
Estimator selection for closed-population capture: recapture
Thomas R. Stanley, Kenneth P. Burnham
1998, Journal of Agricultural, Biological, and Environmental Statistics (3) 131-150
For valid statistical inference, it is important to select an appropriate statistical model. In the analysis of capture-recapture data under the closed-population models of Otis et al. (1978), information theoretic and hypothesis testing approaches to model selection are not practical, because some of the models have likelihoods with nonidenti- fiable...
A policy model to initiate environmental negotiations: Three hydropower workshops
Berton Lee Lamb, Jonathan G. Taylor, Nina Burkardt, Phadrea D. Ponds
1998, Human Dimensions of Wildlife: An International Journal (3) 1-17
How do I get started in natural resource negotiations? Natural resource managers often face difficult negotiations when they implement laws and policies regulating such resources as water, wildlife, wetlands, endangered species, and recreation. As a result of these negotiations, managers must establish rules, grant permits, or create management plans. The...
A nowcast model for tides and tidal currents in San Francisco Bay, California
Ralph T. Cheng, Richard E. Smith
1998, Conference Paper
National Oceanographic and Atmospheric Administration (NOAA) installed Physical Oceanographic Real-Time System (PORTS) in San Francisco Bay, California to provide observations of tides, tidal currents, and meteorological conditions. PORTS data are used for optimizing vessel operations, increasing margin of safety for navigation, and guiding hazardous material spill prevention and response. Because...
Flow and suspended particulate transport in a tidal bottom layer, south San Francisco Bay, California
R. T. Cheng, J. W. Gartner, D.A. Cacchione, G. B. Tate
1998, Conference Paper, Physics of estuaries and coastal seas: Proceedings of the 8th International Biennial Conference on Physics of Estuaries and Coastal Seas
Field investigations of the hydrodynamics and the resuspension and transport of particulate matter in a bottom boundary layer were carried out in South San Francisco Bay, California during March-April 1995. The GEOPROBE, an instrumented bottom tripod, and broad-band acousti Doppler current profilers were used in this investigation. The instrument assemblage...
Predation by ruffe (Gymnocephalus cernuus) on fish eggs in Lake Superior

Ruffe (Gymnocephalus cernuus) were introduced to North America in the Duluth, Minnesota—Superior, Wisconsin harbor, which is the westernmost point on the Laurentian Great Lakes. The species proliferated in the harbor and became the subject of research which has gradually revealed certain...

Mercury accumulation in transplanted Hypogymnia physodes lichens downwind of Wisconsin chlor-alkali plant
M.M. Makholm, J. P. Bennett
1998, Water, Air, & Soil Pollution (102) 427-436
Emissions of mercury from a chlor-alkali plant in central Wisconsin have raised concern about possible effects on biota in the area. Samples of the lichen Hypogymnia physodes, which no longer grows in the area, were transplanted from a site in northeastern Wisconsin and positioned on plastic stands at varying distances...
Interaction between introduced trout and larval salamanders (Ambystoma macrodactylum) in high-elevation lakes
T. Tyler, W.J. Liss, L. Ganio, Gary L. Larson, Robert L. Hoffman, E. Deimling, G.A. Lomnicky
1998, Conservation Biology (12) 94-105
The larval stage of the long-toed salamander (Ambystoma macrodactylum) is the top vertebrate predator in high-elevation fishless lakes in the North Cascades National Park Service Complex, Washington (U.S.A.). Although most of these high-elevation lakes were naturally fishless, trout have been stocked in many of them. We sought to determine the...

1998, Archiv fur Hydrobiologie (142) 71-93
Phytoplankton assemblages in high-elevation lakes of North Cascades National Park Service Complex were studied during the open-water period in 1989. Collectively, 93 taxa were identified in 55 samples from 51 lakes. Based on cell densities, cyanobacteria had the highest relative abundance (36.7 %), followed by chlorophytes (29.8 %), and chrysophytes...
