Benzene oxidation coupled to sulfate reduction
Derek R. Lovley, J.D. Coates, J.C. Woodward, Elizabeth J.P. Phillips
1995, Applied and Environmental Microbiology (61) 953-958
Highly reduced sediments from San Diego Bay, Calif., that were incubated under strictly anaerobic conditions metabolized benzene within 55 days when they were exposed initially to I μM benzene. The rate of benzene metabolism increased as benzene was added back to the benzene-adapted sediments. When a [14C]benzene tracer was included...
Simulation of interaction between ground water in an alluvial aquifer and surface water in a large braided river
S. A. Leake, M. R. Lilly
1995, Conference Paper, International Symposium on Groundwater Management - Proceedings
The Fairbanks, Alaska, area has many contaminated sites in a shallow alluvial aquifer. A ground-water flow model is being developed using the MODFLOW finite-difference ground-water flow model program with the River Package. The modeled area is discretized in the horizontal dimensions into 118 rows and 158 columns of approximately 150-meter...
Common ravens in the southwestern United States, 1968-92
William I. Boarman, Kristin H. Berry
Edward T. LaRoe, Gaye S. Farris, Catherine E. Puckett, Peter D. Doran, Michael J. Mac, editor(s)
1995, Book chapter, Our living resources: A report to the nation on the distribution, abundance, and health of U.S. plants, animals, and ecosystems
The common raven (Corvus corax) is a large black passerine bird found throughout the northern hemisphere including western and northern North America. Ravens are scavengers that frequently feed on road-killed animals, large dead mammals, and human refuse. They kill and eat prey including rodents, lambs (Larsen and Dietrich 1970), birds,...
Find the fish: using PROC SQL to build a relational database
Mary C. Fabrizio, Scott N. Nelson
1995, Book chapter, Client/server computing with the SAS system: tips and techniques
Reliable estimates of abundance and survival, gained through mark-recapture studies, are necessary to better understand how to manage and restore lake trout populations in the Great Lakes. Working with a 24-year data set from a mark-recapture study conducted in Lake Superior, we attempted to disclose information on tag shedding...
Patterns of egg deposition by lake trout and lake whitefish at Tawas artificial Reef, Lake Huron, 1990-1993
N.R. Foster, G.W. Kennedy
M. Munawar, T. Edsall, J. Leach, editor(s)
1995, Book chapter, The Lake Huron ecosystem: ecology, fisheries, and management
In August 1987, the Michigan Department of Natural Resources (MDNR), with the help and co-sponsorship of Walleyes for Iosco County, constructed Tawas artificial reef to improve recreational fishing in Tawas Bay. Post-construction assessment in October, 1987, by the MDNR found twice as many adult lake trout in a gill...
Continental climate response to orbital forcing from biogenic silica records in Lake Baikal
Steven M. Colman, J.A. Peck, E.B. Karabanov, Susan J. Carter, J.P. Bradbury, J.W. King, D. F. Williams
1995, Nature (378) 769-771
CHANGES in insolation caused by periodic changes in the Earth's orbital parameters provide the primary forcing for global ice ages1-6. But it is not clear to what extent the climates in continental interiors are controlled directly by regional variations in insolation and to what extent they are driven instead by...
Evidence of Emperor Geese breeding in Russia and staging in Alaska
Joel A. Schmutz, Alexander V. Kondratyev
1995, The Auk (112) 1037-1038
Emperor Geese (Chen canagica) breed primarily on the Yukon-Kuskokwim Delta, Alaska (Eisenhauer and Kirkpatrick 1977), but a small, poorly quantified proportion of the world's population is known to breed in the Russia Far East (Kistchinski 1976, 1988, Portenko 1981). Eisenhauer and Kirkpatrick (1977) stated that 80 to 90% of all...
Areal extent of freshwater from an experimental release of Mississippi River Water into Lake Pontchartrain, Louisiana, May 1994
Brian E. McCallum
1995, Conference Paper, Coastal Zone: Proceedings of the Symposium on Coastal and Ocean Management
The effects of the release of freshwater from the Mississippi river into the Lake Pontchartrain was evaluated. The study determined the delineation of the areal extent of the freshwater plume in the lake, intensively sampled lake and river water and bed sediment to determine the effects on water quality in...
Transfer and accumulation of organochlorines from black-crowned night-heron eggs to chicks
T. W. Custer, Christine M. Custer
1995, Environmental Toxicology and Chemistry (14) 533-536
Eggs and sibling 1-, 3-, and 5-d-old chicks from seven black-crowned night-heron (Nycticorax nycticorax) broods were collected from Green Bay, Wisconsin, and analyzed for organochlorines. The concentration (μg/g) of nine organochlorines either decreased (n = 7) or remained the same (n = 2) as the chicks grew older. In contrast, the total...
Contraction scour at a bridge over Wolf Creek, Iowa
Edward E. Fischer
Espey William H.Combs Phil G., editor(s)
1995, Conference Paper, International Water Resources Engineering Conference - Proceedings
Contraction scour at the State Highway 14 bridge over Wolf Creek in south-central Iowa was caused by a large flood on September 14 and 15, 1992. The bridge is a 30.5-m, single-span steel structure supported by vertical-wall concrete abutments with wingwalls. Approximately 6 meters of scour resulted from the flood....
Mapping the response of riparian vegetation to possible flow reductions in the Snake River, Idaho
W. Carter Johnson, Mark D. Dixon, Robert W. Simons, Susan Jenson, Kevin Larson
1995, Geomorphology (13) 159-173
This study was initiated to determine the general effects of potential flow reductions in the middle Snake River (Swan Falls Dam downstream to the Idaho-Oregon border) on its riparian vegetation. Considerable water from the river is currently used to irrigate the adjacent Snake River Plain, and increased demand for water...
[Book review] Skua and penguin: Predator and prey
