Assessment of sea lamprey (Petromyzon marinus) predation by recovery of dead lake trout (Salvelinus namaycush) from Lake Ontario, 1982-85
Roger A. Bergstedt, Clifford P. Schneider
1988, Canadian Journal of Fisheries and Aquatic Sciences (45) 1406-1410
During 1982-85, 89 dead lake trout (Salvelinus namaycush) were recovered with bottom trawls in U.S. waters of Lake Ontario: 28 incidentally during four annual fish-stock assessment surveys and 61 during fall surveys for dead fish. During the assessment surveys, no dead lake trout were recovered in April-June, one was recovered...
Characterization of an avian cholera epizootic in wild birds in western Nebraska
R. M. Windingstad, S.M. Kerr, R. M. Duncan, C. J. Brand
1988, Avian Diseases (32) 124-131
Avian cholera killed an estimated 2500 birds in western Nebraska and eastern Wyoming from 28 November 1985 to late January 1986. Wild mallards (Anas platyrhynchos) suffered the most losses. Other wild waterfowl, wild turkeys (Meleagris gallopavo), a few domestic fowl, and a bald eagle (Haliaeetus leucocephalus) also died. Pasteurella multocida...
The Goodman swell: A lithospheric flexure caused by crustal loading along the midcontinent rift system
Z. E. Peterman, P.K. Sims
1988, Tectonics (7) 1077-1090
Rb-Sr biotite ages of Archean and Early to Middle Proterozoic crystalline rocks in northern Wisconsin and adjacent Upper Peninsula of Michigan describe a regionally systematic pattern related to differential uplift. An “age low” occurs in northern Wisconsin where values range from 1070–1172 Ma for rocks with crystallization ages of 1760...
Geologic structure of the northern New Caledonia ridge, as inferred from magnetic and gravity anomalies
J.-Y. Collot, P. Rigolot, F. Missegue
1988, Tectonics (7) 991-1013
Bathymetric, gravity, and magnetic data collected in the southwest Pacific Ocean over the northern New Caledonia ridge show that the main geological units known from the island of New Caledonia extend northward from this island, beneath the Grand Lagon Nord, the Grand Passage, and the d'Entrecasteaux reefs. These data support...
Tectonics of formation, translation, and dispersal of the Coast Range ophiolite of California
R. J. McLaughlin, M.C. Blake Jr., A. Griscom, C.D. Blome, B. Murchey
1988, Tectonics (7) 1033-1056
Data from the Coast Range ophiolite and its tectonic outliers in the northern California Coast Ranges suggest that the lower part of the ophiolite formed 169 to 163 Ma in a forearc or back arc setting at equatorial latitudes. Beginning about 156 Ma and continuing until 145 Ma, arc magmatism...
Influence of the method of fluoride administration on toxicity and fluoride concentrations in Japanese quail
W. James Fleming, C.A. Schuler
1988, Environmental Toxicology and Chemistry (7) 841-845
Young Japanese quail (Coturnix japonica) were administered NaF for 16 d either in their diet or by esophageal intubation. Based on the total fluoride ion (Σmg F−) intake over the 16-d experimental period, fluoride administered by intubation was at least six times more toxic than that fed in the diet....
MARKOV: A methodology for the solution of infinite time horizon MARKOV decision processes
B. Kenneth Williams
1988, Applied Stochastic Models and Data Analysis (4) 253-271
Algorithms are described for determining optimal policies for finite state, finite action, infinite discrete time horizon Markov decision processes. Both value-improvement and policy-improvement techniques are used in the algorithms. Computing procedures are also described. The algorithms are appropriate for processes that are either finite or infinite, deterministic or stochastic, discounted...
