2003, Conference Paper, Technical Council on Lifeline Earthquake Engineering Monograph
The discovery of oil on Alaska's North Slope and the construction of a pipeline to transport that oil across Alaska coincided with the National Environmental Policy Act of 1969 and a destructive Southern California earthquake in 1971 to cause stringent stipulations, state-of-the-art investigations, and innovative design for the pipeline. The...

Characterization of limestone reacted with acid-mine drainage in a pulsed limestone bed treatment system at the Friendship Hill National Historical Site, Pennsylvania, USA
Jane M. Hammarstrom, Philip Sibrell, Harvey E. Belkin
2003, Applied Geochemistry (18) 1705-1721
Armoring of limestone is a common cause of failure in limestone-based acid-mine drainage (AMD) treatment systems. Limestone is the least expensive material available for acid neutralization, but is not typically recommended for highly acidic, Fe-rich waters due to armoring with Fe(III) oxyhydroxide coatings. A new AMD treatment technology that uses...
A new species of Moraria (Crustacea: Copepoda: Harpacticoida) from the Laurentian Great Lakes
Janet W. Reid, Lynn T. Lesko
2003, Zootaxa (205) 1-19
Moraria hudsoni n. sp. is described from Trails End Bay in Lake Michigan and Prentiss Bay in Lake Huron, Michigan, USA. The new species differs from its congeners in chaetotaxy, body ornamentation, and other characters. We review published records of members of Moraria from North and Central America;...

Sarcocysts of an unidentified species of Sarcocystis in the sea otter (Enhydra lutris)
J. P. Dubey, D. S. Lindsay, B.M. Rosenthal, N. J. Thomas
2003, Journal of Parasitology (89) 397-399
The number of Sarcocystis species that infect sea otters (Enhydra lutris) is unknown. Sea otter tissues were recently shown to harbor sarcocysts of S. neurona and of unidentified species of Sarcocystis. Whereas sarcocysts of S. neurona have walls 1–3 μm thick with type 9 villar protrusions, ultrastructure...

Introduction to fire danger rating and remote sensing - Will remote sensing enhance wildland fire danger prediction?

2003, Series in Remote Sensing 4-1
While ‘Fire Danger’ per se cannot be measured, the physical properties of the biotic and abiotic world that relate to fire occurrence and fire behavior can. Today, increasingly sophisticated Remote Sensing methods are being developed to more accurately detect fuel properties such as species composition (fuel...

Five races of cottontail rabbits belonging to three species occur in Virginia. One of them, the Mearns cottontail (Sylvilagus floridanus mearnsi), is reported here for the first time. It occurs in six southwestern counties of the state, while the eastern cottontail (S. f. mallurus) occurs in the remainder of...

Update COSEWIC status report on the shortjaw cisco, Coregonus zenithicus, in Canada

2003, Report, COSEWIC assessment and update status report on the shortjaw cisco Coregonus zenithicus in Canada
Extirpated in most of the Great Lakes, the shortjaw cisco, Coregonus zenithicus, is currently found in Lakes Superior and Nipigon in addition to at least 22 Canadian lakes. The species exhibits morphological and genetic variability throughout its range and may consist of more than one distinct taxon. However, a common...

Characterization of Pasteurella multocida isolates from wetland ecosystems during 1996 to 1999
M.D. Samuel, D.J. Shadduck, Diana R. Goldberg, M. A. Wilson, D.O. Joly, M. A. Lehr
2003, Journal of Wildlife Diseases (39) 798-807
We cultured 126 Pasteurella multocida isolates, 92 from water and 34 from sediment samples collected from wetlands in the Pacific and Central flyways of the United States between 1996 and 1999. Most (121) of the isolates were P. multocida serotype 1, but serotypes 3, 3/4, 10, and 11 were also...
A review of lake trout (Salvelinus namaycush) restoration in Lake Ontario from an early life history perspective
John Fitzsimons, Brian F. Lantry, Robert O’Gorman
M. Munawar, editor(s)
2003, Book chapter, The state of Lake Ontario: past, present and future
The authors conclude that small numbers of lake trout spawned successfully each year during 1992-97 in Lake Ontario, although this has yet to result in a trend of increasing natural reproduction. Juxtaposed with the high abundance of mature fish (Selgeby et al., 1995), the situation in Lake Ontario suggests...
Effects of subcutaneous transmitter implants on behavior, growth, energetics, and survival of common loon chicks
K.P. Kenow, M.W. Meyer, F. Fournier, W. H. Karasov, A. Elfessi, S. Gutreuter
2003, Journal of Field Ornithology (74) 179-186
High rates of Common Loon (Gavia immer) chick mortality have been documented in Wisconsin, especially on acidic lakes, but causes and timing of chick mortality are poorly understood. We modified and evaluated a subcutaneous transmitter implant technique for Common Loon chicks using wild and captive reared chicks. Results indicated that...
Egg-to-fry survival of two strains of Atlantic salmon (Salmo salar) in stream incubators under laboratory conditions
James H. Johnson
2003, Journal of Freshwater Ecology (18) 499-500
Egg-to-fry survival of two strains of Atlantic salmon (Salmo salar) was evaluated under laboratory conditions in two commercial stream egg incubators. The survival was also examined based on egg developmental stage (i.e., green eggs, eyed egggs, advanced eggs). There was no significant difference in survival of eggs in the Jordan-Scotty...
The influence of partial clutch depredation on duckling production
Joshua T. Ackerman, J.M. Eadie, D.L. Loughman, G.S. Yarris, M.R. McLandress
2003, Journal of Wildlife Management (67) 576-587
Nest depredation is the foremost cause of reproductive failure in waterfowl. Management strategies typically have focused on reducing predator contact with nests, yet the late of nests after predators have found them has received little attention. Although nest depredation can result in complete clutch loss, nests often are only partially depredated and the remaining clutch may be successful....
The offshore fish community in southern Lake Ontario, 1972-1998
Randall W. Owens, Robert O’Gorman, Thomas H. Eckert, Brian F. Lantry
M. Munawar, editor(s)
2003, Book chapter, State of Lake Ontario: past, present and future
The authors document the status of Lake Ontario's open-water fish community in 1972, near the beginning of an era of massive fish stocking and when phosphorus levels in the lake from anthropogenic inputs, were near their peak. They then describe changes that occurred in the fish community in 1978-98....
