The stress of Formalin treatments in rainbow trout (Salmo gairdneri) and coho salmon (Oncorhynchus kisutch)
Gary Wedemeyer
1971, Journal of the Fisheries Research Board of Canada (28) 1899-1904
Changes in gill function, acid–base balance and pituitary activation occurring during standard 200 ppm formalin treatments of juvenile rainbow trout (Salmo gairdneri) and coho salmon (Oncorhynchus kisutch) were compared. Plasma Cl−, Ca++, total CO2, and interrenal vitamin C in the trout declined continuously and in proportion to the exposure time, but...
Interaction between duck hepatitis virus and DDT in ducks
W.L. Ragland, Milton Friend, D.O. Trainer, N.E. Sladek
1971, Research Communications in Chemical Pathology and Pharmacology (2) 236-244
Injections of duck hepatitis virus (DVH) decreased, and exposure to DDT increased, hepatic microsomal mixed-function oxidase activity. Injection of DFV prior to exposure to DDT did not prevent stimulation of hepatic microsomal mixed-function oxidase activity by DDT and may have enhanced it....
Alewife dieoffs: Why do they occur?
Peter J. Colby
1971, Limnos (4) 18-27
Periodid midwinter, early spring, and summer mortalities of alewives (Alosa pseudoharengus) have been common in the Great Lakes since the first appearance of the silvery marine invader in Lake Ontario in the mid-1870's. In 1967 a nationally publicized dieoff of tremendous magnitude (estimated at several hundred million pounds of...

Na+, K+-activated-ATPase inhibition in rainbow trout: A site for organochlorine pesticide toxicity?
Paul W. Davis, Gary A. Wedemeyer
1971, Comparative Biochemistry and Physiology, Part B: Comparative Biochemistry (40) 823-827
1. The Na+, K+-activated, Mg2+-dependent-ATPase enzyme system in a heavy microsomal fraction of rainbow trout (Salmo gairdneri) brain was inhibited in vitro by chlorinated hydrocarbon pesticides.2. T50 (concentration at 50 per cent inhibition) values for dicofol, endosulfan and DDT were <span class="formulatext stixSupport mathImg" title="Click to view...
Albinism in lampreys in the upper Great Lakes
Robert A. Braem, Everett L. King
1971, Copeia (1971) 176-179
Albinism in fishes is relatively rare except in some stocks of hatchery-reared salmonids. In the Petromyzonidae, only four albino lampreys have been reported....

Thermoluminescence of Apollo 12 lunar samples
Richard R. Doell, G. Brent Dalrymple
1971, Earth and Planetary Science Letters (10) 357-360
Thermoluminescence (TL) glow curve and decay characteristics of Apollo 12 fines and soil samples are similar to those from Apollo 11. Interpretation of the results from the core sample is difficult because of inadequate sample, spacing, but it appears that the part...
Calcium-magnesium carbonate solid solutions from Holocene conglomerate cements and travertines in the Coast Range of California
I. Barnes, J. R. O’Neil
1971, Geochimica et Cosmochimica Acta (35) 699-718
Two calcium-magnesium carbonate solid solutions form Holocene travertines and conglomerate cements in fresh water stream channels of the Coast Range of California. Calcite does not yield the {015} diffraction maximum. The {006} diffraction maximum is lacking over most of the range of composition...
Trees and streams: The efficiency of branching patterns
Luna Bergere Leopold
1971, Journal of Theoretical Biology (31) 339-354
Extending the analysis of branching patterns of the drainage net of rivers, originated by Horton, the relation of average numbers and lengths of tree branches to size of branch was investigated. Size of branch was defined by branch order, or its position in the hierarchy of tributaries. It was found...
Visceral granuloma in brook trout (Salvelinus fontinalis)
C. E. Dunbar, R. L. Herman
1971, Journal of Nutrition (101) 1445-1452
Brook trout were fed a synthetic diet with suspect diet components added or a meat-meal diet with individual components removed to determine their effect on the incidence of visceral granuloma. Removal or addition of cottonseed meal had the greatest effect on incidence. Gossypol was not the causative agent. The disease...
Geological provinces of the near side of the moon
J.F. McCauley, D.E. Wilhelms
1971, Icarus (15) 363-367
Systematic geologic mapping of the near side of the Moon has provided the basis for defining and delineating the major geological provinces of the near side. From the nature of the provinces and their distribution patterns a general historical sequence evolves. Five main...
On the origin of lunar soil 12033
P.A. Beadecker, F. Cuttitta, H. J. Rose Jr., R. Schaudy, J. T. Wasson
1971, Earth and Planetary Science Letters (10) 361-364
The lunar soil 12033 is compositionally distinctly different from both the local rocks at the Apollo 12 site and other lunar samples. It must be a recent deposit, else it would not have retained its identity. It contains a meteoritic component which...

Variation of iridium in a differentiated tholeiitic dolerite
L. P. Greenland
1971, Geochimica et Cosmochimica Acta (35) 319-322
Iridium has been determined in a drill core from the Great Lake (Tasmania) dolerite sheet. Iridium decreases systematically from the mafic dolerites (0.25 ppb) to the granophyres (0.006 ppb). The trend with differentiation closely parallels that of chromium....
Isotopic composition of strontium in three basalt-andesite centers along the Lesser Antilles arc
C. E. Hedge, J.F. Lewis
1971, Contributions to Mineralogy and Petrology (32) 39-47
Si87/Sr86 ratios have been determined for lavas and py lastic rocks from three basalt-andesite centers along the Lesser Antilles arc—Mt. Misery on the island of St. Kitts, Soufriere on the island of St. Vincent, and Carriacou, an island of The Grenadines. The average Si87/Sr86 content of these rocks...
Scanning electron microscopy of clays and clay minerals
B.F. Bohor, R.E. Hughes
1971, Clays and Clay Minerals (19) 49-54
The scanning electron microscope (SEM) proves to be ideally suited for studying the configuration, texture, and fabric of clay samples. Growth mechanics of crystalline units—interpenetration and interlocking of crystallites, crystal habits, twinning, helical growth, and topotaxis—also are uniquely revealed by the SEM.Authigenic kaolins make up the bulk of the examples...

Giant American brook lampreys, Lampetra lamottei, in the upper Great Lakes
Patrick J. Manion, Harold A. Purvis
1971, Journal of the Fisheries Research Board of Canada (28) 616-620
Five female American brook lampreys, Lampetra lamottei, collected in lakes Michigan and Huron averaged nearly twice as long and about six times as heavy as American brook lampreys of normal size. Three factors suggested that the giant lampreys may have fed parasitically after metamorphosis: morphological adaptations of the species for parasitic...

A program for plotting bathythermograph transect data on a computer (IBM 1130) printer is available from the Great Lakes Fishery Laboratory. Temperature values are printed in positions proportional to their depths and distances from shore. Contour lines are drawn manually through the plotted points....
Sea lampreys in the Great Lakes of North America
Bernard R. Smith
M.W. Hardisty, I.C. Potter, editor(s)
1971, Book chapter, The biology of lampreys
The movement of sea lampreys into the upper Great Lakes (Superior, Michigan, and Huron) initiated a series of biological changes which have extended beyond the fish directly attacked by the parasite. The threat posed by the sea lamprey was not generally recognized until it was well established in all...
