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...
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...
Certainty of paternity and paternal investment in eastern bluebirds and tree swallows
Bart Kempenaers, Richard B. Lanctot, Raleigh J. Robertson
1998, Animal Behaviour (55) 845-860
Extra-pair paternity is common in many socially monogamous passerine birds with biparental care. Thus, males often invest in offspring to which they are not related. Models of optimal parental investment predict that, under certain assumptions, males should lower their investment in response to reduced certainty of paternity. We attempted to...
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...
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...
Effect of water acceleration on downstream migratory behavior and passage of Atlantic salmon smolts and juvenile American shad at surface bypasses
A. Haro, M. Odeh, J. Noreika, T. Castro-Santos
1998, Transactions of the American Fisheries Society (127) 118-127
Behavior and passage rate of smolts of Atlantic salmon Salmo salar and juvenile American shad Alosa sapidissima were compared between a standard (sharp‐crested) and a modified surface bypass weir that employs uniform flow velocity increase (1 m·s−1·m−1 of linear distance). Within the first 30 min after release, significantly more smolts passed the modified weir than...

1998, Oecologia (114) 389-404
Although there is a great deal of information concerning responses to increases in atmospheric CO2 at the tissue and plant levels, there are substantially fewer studies that have investigated ecosystem-level responses in the context of integrated carbon, water, and nutrient cycles. Because our understanding of ecosystem responses to elevated CO2...
Trace element trophic transfer in aquatic organisms: A critique of the kinetic model approach
J.R. Reinfelder, N.S. Fisher, S. N. Luoma, J.W. Nichols, W.-X. Wang
1998, Science of the Total Environment (213) 117-135
The bioaccumulation of trace elements in aquatic organisms can be described with a kinetic model that includes linear expressions for uptake and elimination from dissolved and dietary sources. Within this model, trace element trophic transfer is described by four parameters: the weight-specific ingestion rate (IR); the assimilation efficiency (AE); the...
Hydrology and quality of ground water in northern Thurston County, Washington
B. W. Drost, G. L. Turney, N. P. Dion, M. A. Jones
1998, Water-Resources Investigations Report 92-4109
Northern Thurston County is underlain by as much as 1,800 feet of unconsolidated deposits of Pleistocene Age that are of glacial and nonglacial origin. Iterpretation of approximately 1,140 drillers' logs led to the delineation of seven major geohydrologic units, four of which are significant aquifers. Precipitation ranges from about 35...
