Limnological survey of Lake Erie 1959 and 1960
Alfred M. Beeton
1963, Technical Report 6
Federal, provincial, state, and university organizations participated in cooperative limnological surveys of Lake Erie in September 1959 and August 1960 to determine the extent and severity of the low dissolved-oxygen content of the hypolimnetic waters. Observations were restricted to the central basin in 1959, but were lake-wide in 1960....
Hydrogen-water vapor mixtures: Control of hydrothermal atmospheres by hydrogen osmosis
H. R. Shaw
1963, Science (139) 1220-1222
Experiments at 700°C and 800 bars total pressure demonstrate positive deviations from ideality for mixtures of hydrogen and H2O gases. The deviations are greater than predicted with Stockmayer's method. The composition of the mixture and the fugacity of hydrogen are controlled by diffusing hydrogen through metallic membranes. The results give...
Implications of the minor element content of some major streams of the world
W. H. Durum, J. Haffty
1963, Geochimica et Cosmochimica Acta (27) 1-11
Of 15 or more minor elements in the world's principal river waters only aluminum, iron, manganese, barium and strontium range much over 100 μgl">100 μgl. (parts per billion). Most minor elements range at or below 100 μg1">100 μg1. and have...
Study of multicomponent mixtures in solution with a vertical-axis transmission-type filter-fluorometer
M. H. Fletcher
1963, Analytical Chemistry (35) 278-288
Fluorescence intensity, sensitivity, and the effect of diverse ions are discussed in relation to chemical equilibrium and the general equation for fluorescence. High sensitivity is the common denominator in eliminating or reducing all types of interference and the general equation is the key for quickly selecting conditions that give maximum...
Antiferromagnetism of UO2⋅2H2O
T. Pankey, F. E. Senftle, F. Cuttitta
1963, Journal of Chemical Physics (39) 1702-1706
Magnetic susceptibility measurements have been made on UO2·xH2O for x=1.78 to x=2.13, and from 77° to 375°K. As the value of x decreased the susceptibility increased. Both these data and structural arguments imply that the formula of this compound is U(OH)4 rather than the dihydrate form. Based on this concept the data have been corrected...
Two new Gyrodactylus (Trematoda: Monogenea) from cyprinid fishes with synopsis of those found on North American fishes
R.E. Putz, G. L. Hoffman
1963, Journal of Parasitology (49) 559-566
Gyrodactylus atratuli from the blacknose dace (Rhinichthys atratulus) and the pearl dace (Semotilus margarita) is compared with known species of Gyrodactylus from North American fishes and described as a new species. Gyrodactylus margaritae from the pearl dace (Semotilus margarita) is compared with known species of Gyrodactylus from North American fishes...
Studies on Neogogatea kentuckiensis (Cable, 1935) n. comb.: (Trematoda: Strigeoidea: Cyathocotylidae)
G. L. Hoffman, C. E. Dunbar
1963, Journal of Parasitology (49) 737-744
The cercaria of N. kentuckiensis was found in Anaplocamus dilatatus (Nitrocris d.) and Mudalia carinata. The metacercaria was found in all fishes examined from Opequon River, West Virginia, except Cottus bairdi which was also refractory to experimental infection. Two species of Centrarchidae, four of Cyprinidae, three of Salmonidae, Etheostoma flabellare,...
Publications on fish parasites and diseases, 330 B.C.-A.D. 1923
E.A. McGregor
1963, Report
These references were collected in 1924, but until now this collection has been available only in manuscript:fbrm. Because of the current increased interest in this field, this bibliography is being issued to make it more generally accessible. They include the earliest known references to fish parasites (330 B. C.) as...
Population analyses, variation and behavior of Anguispira alternata alternata
Charles L. Douglas
1963, Transactions of the Kansas Academy of Science (66) 186-194
Anguispira alternata alternata is one of the more common terrestrial snails in the United States. Gregarious by nature, these snails can be collected in large numbers from wooded flood-plains and moist upland wooded areas. "The range is eastern Canada and the United States, from Nova Scotia to Lake of...
Biological Laboratory, Ann Arbor, Michigan
James W. Moffett
1963, American Zoologist (3) 374-375
This laboratory located about 40 miles west of Detroit, near the intersection of highways I-94 and US-23, can be reached by bus, railroad, or via commercial airlines to Detroit Willow Run or Metropolitan airports. Field biological stations are located in Wisconsin at Ashland; in Ohio at Sandusky; and in Michigan...
Floods in Wyoming, magnitude and frequency
J. R. Carter, A. Rice Green
1963, Circular 478
This report contains the results of four separate flood-frequency analyses designated A, B, C, and D. Analysis A is for the portion of Wyoming east of the Continental Divide. Analysis B applies to the portion of Wyoming in Part 9, as designated in streamflow reports entitled "Surface Water Supply of...
Late Pleistocene glacial drainage in the Devils Lake Region, North Dakota
Saul Aronow
1963, GSA Bulletin (74) 859-874
The Devils Lake region of northeastern North Dakota is covered with glacial drift deposited by the Leeds lobe of the Mankato Substage of the Wisconsin Stage of the Pleistocene and is underlain by Pierre Shale of Cretaceous age. Associated with the Sheyenne River, which flows through the southern part of...
Some phases of the life history of the trout-perch
John L. Magnuson, Lloyd L. Smith
1963, Ecology (44) 83-95
The trout-perch, Percopsis omiscomaycus (Walbaum), is one of the more abundant forage fishes in the larger lakes of midwestern United States and central Canada where walleye, Stizostedion v. vitreum (Mitchill), yellow perch, Perca flavescens (Mitchill), and coregonids predominate. It has been suggested that it may have considerable effect on...
Age and growth of the whitefish in Lake Superior
William R. Dryer
1963, Fishery Bulletin (63) 77-95
The average annual commercial production of whitefish in the U.S. waters of Lake Superior dropped from 2,194,000 pounds in 1879-1908 to 504,000 pounds in 1911-59. The modern production, though far below the earlier, has accounted for more than 10 percent of the total value of the fishery in all...
