Quantitative PCR analysis of CYP1A induction in Atlantic salmon (Salmo salar)
C.B. Rees, S. D. McCormick, Heuvel Vanden, W. Li
2003, Aquatic Toxicology (62) 67-78
Environmental pollutants are hypothesized to be one of the causes of recent declines in wild populations of Atlantic salmon (Salmo salar) across Eastern Canada and the United States. Some of these pollutants, such as polychlorinated biphenyls and dioxins, are known to induce expression of the CYP1A subfamily of genes. We...

P.A. Conrads, W.P. Martello, N.R. Sullins
2003, Environmental Monitoring and Assessment (81) 97-106
The Total Maximum Daily Load (TMDL) for ammonia and biochemical oxygen demand for the Pee Dee, Waccamaw, and Atlantic Intracoastal Waterway system near Myrtle Beach, South Carolina, mandated a 60-percent reduction in point-source loading. For waters with a naturally low background dissolved-oxygen concentrations, South Carolina anti-degradation rules in the water-quality...
Automated storm water sampling on small watersheds
R. D. Harmel, K. W. King, R.M. Slade
2003, Applied Engineering in Agriculture (19) 667-674
Few guidelines are currently available to assist in designing appropriate automated storm water sampling strategies for small watersheds. Therefore, guidance is needed to develop strategies that achieve an appropriate balance between accurate characterization of storm water quality and loads and limitations of budget, equipment, and personnel. In this article, we...

J. D. Bales
2003, Estuaries (26) 1319-1328
Hurricane Floyd in September 1999 caused disastrous flooding from South Carolina to Massachusetts in the United States, with particularly severe and prolonged flooding in eastern North Carolina resulting in record flood-flow loadings of freshwater and contaminants to Pamlico Sound, North Carolina. The inland flooding, water quality, and loadings to Pamlico...

J.M. Ebeling, P.L. Sibrell, S.R. Ogden, S.T. Summerfelt
2003, Aquacultural Engineering (29) 23-42
An evaluation of two commonly used coagulation-flocculation aids (alum and ferric chloride) was conducted for the supernatant overflow from settling cones used to treat the effluent from microscreen filters in an intensive recirculating aquaculture system. In addition to determining the effectiveness of these aids in removing both suspended solids and...

G.A. Olyphant, Joan Thomas, R.L. Whitman, D. Harper
2003, Environmental Monitoring and Assessment (81) 289-300
Two watersheds in northwestern Indiana were selected for detailed monitoring of bacterially contaminated discharges (Escherichia coli) into Lake Michigan. A large watershed that drains an urbanized area with treatment plants that release raw sewage during storms discharges into Lake Michigan at the outlet of Burns Ditch. A small watershed drains...
Toggling of seismicity by the 1997 Kagoshima earthquake couplet: A demonstration of time-dependent stress transfer
S. Toda, R. Stein
2003, Journal of Geophysical Research B: Solid Earth (108)
Two M ??? 6 well-recorded strike-slip earthquakes struck just 4 km and 48 days apart in Kagoshima prefecture, Japan, in 1997, providing an opportunity to study earthquake interaction. Aftershocks are abundant where the Coulomb stress is calculated to have been increased by the first event, and they abruptly stop where...
Effects of life history variation on size and growth in stream-dwelling Atlantic salmon
B. H. Letcher, G. Gries
2003, Journal of Fish Biology (62) 97-114
A large size variation amongst life histories for stream-dwelling Atlantic salmon Salmo salar was found and the relative effect of life histories on size varied over time. As early as December (age 0+ years), fish that later smolted at age 2+ years were significantly larger than fish that did not...
Geomorphic, water quality and fish community patterns associated with the distribution of Notropis topeka in a Central Missouri Watershed
M.A. Bayless, M.G. McManus, J.F. Fairchild
2003, American Midland Naturalist (150) 58-72
The Topeka shiner (Notropis topeka) is a small native cyprinid species that has declined throughout its range in the Central Great Plains Region of the United States. Declines of the species have been associated with numerous factors including water quality, physical habitat alteration and predation. The N. topeka occurs in...

2003, Ambio (32) 145-152
This study focuses on assessing the state of population distribution, land cover distribution, biodiversity hotspots, and protected areas in global coastal zones. The coastal zone is defined as land within 100 km of the coastline. This study attempts to answer such questions as: how crowded are the coastal zones, what...
Surface water qualit: Revisiting nitrate concentrations in the Des Moines River: 1945 and 1976-2001
G.F. McIsaac, R.D. Libra
2003, Journal of Environmental Quality (32) 2280-2289
Recent compilations of historical and contemporary riverine nitrate (NO3) concentrations indicate that concentrations in many rivers in the north-central USA increased during the second half of the 20th century. The Des Moines River near Des Moines, Iowa, however, was reported to have had similar NO3 concentrations in 1945 and the 1980s,...

Science support for managing migratory waterfowl.
Joseph P. Fleskes, Michael R. Miller, John Y. Takekawa
2003, Report
Migratory birds in North America are an international resource shared by Canada, the United States, and Mexico. Ultimate population management authority in the U.S. lies with the U.S. Fish and Wildlife Service (FWS), but states participate in development of management decisions through the Flyway system. The FWS, state wildlife agencies,...

Effects of fire on fish populations: Landscape perspectives on persistance of native fishes and nonnative fish invasions
J. B. Dunham, M. Young, Robert E. Gresswell, B. Rieman
2003, Forest Ecology and Management (178) 183-196
Our limited understanding of the short and long-term effects of fire on fish contributes to considerable uncertainty in assessments of the risks and benefits of fire management alternatives. A primary concern among the many potential effects of fire is the effects of fire and fire management on persistence of native...
Measurements of thermal updraft intensity over complex terrain using American white pelicans and a simple boundary-layer forecast model
H.D. Shannon, G.S. Young, M. Yates, Mark R. Fuller, W. Seegar
2003, Boundary-Layer Meteorology (104) 167-199
An examination of boundary-layer meteorological and avian aerodynamic theories suggests that soaring birds can be used to measure the magnitude of vertical air motions within the boundary layer. These theories are applied to obtain mixed-layer normalized thermal updraft intensity over both flat and complex terrain from the climb rates of...
Teetering on the edge or too late? Conservation and research issues for avifauna of sagebrush habitats
Steven T. Knick, David S. Dobkin, John T. Rotenberry, Michael A. Schroeder, W. Matthew Vander Haegen, Charles van Riper III
2003, The Condor (105) 611-634
Degradation, fragmentation, and loss of native sagebrush (Artemisia spp.) landscapes have imperiled these habitats and their associated avifauna. Historically, this vast piece of the Western landscape has been undervalued: even though more than 70% of all remaining sagebrush habitat in the United States is publicly owned, <3% of it is...

Capture of breeding and wintering shorebirds with leg-hold noose-mats
K.R. Mehl, K.L. Drake, G. W. Page, Peter M. Sanzenbacher, Susan M. Haig, J.E. Thompson
2003, Journal of Field Ornithology (74) 401-405
Development of effective trapping techniques is important for conservation efforts, as marking and subsequent monitoring of individuals is necessary to obtain accurate estimates of demography, movements, and habitat use. We describe a leg-hold noose-mat trap for capturing breeding and nonbreeding shorebirds. Using this method, we trapped 50 Piping Plovers (Charadrius...
