Disease and infection in the Tetraonidae
C. M. Herman
1963, Journal of Wildlife Management (27) 850-855
Disease is one of many factors advanced to explain the fluctuations of grouse populations, but no profound study of natural disease losses in Tetraonidae exists. The literature contains frequent references to THE grouse disease, although many potential pathogens are listed in numerous surveys and limited investigations, and the relevant data...
A method for drive-trapping dusky grouse
R. E. Tomlinson
1963, Journal of Wildlife Management (27) 563-566
A drive trap, used to capture dusky grouse (Dendragapus obscurus obscurus) females and their broods for transplantation, is described. The trap consists of two 75-foot wings, leading to a netting-covered enclosure with a smaller wooden catch box at the rear. A four-man crew finds a brood in open cover and,...
Television — A new tool for the ground‐water geologist
J.T. Callahan, R. L. Wait, M.J. McCollum
1963, Groundwater (1) 4-6
The television camera has become a tool of the ground‐water geologist, enabling him to examine visually the inside of a well deep below the land surface. Using the camera, the rocks can be viewed in place. Of great importance to the ground‐water studies in coastal Georgia, the camera enables the geologist to see the important <span...
Chemical analyses of surface waters in Colorado, October 1959 to September 1962
Water Resources Division, U.S. Geological Survey
1963, Report
Data presented herein are records of water quality for the period October 1959 to September 1962 for the sampling sites shown below and on the enclosed map. The data are preliminary and subject to revision. Final records are published in the annual series of Geological Survey Water-Supply Papers entitled "Quality...
Recharge rates of principal aquifers in Lake County, Indiana
J.S. Rosenshein
1963, Groundwater (1) 13-20
The upper 350 to 400 feet of rocks underlying Lake County, Indiana, form a single but complex hydrologic system. The rock units composing this system consist (in ascending order) of dolomite, clay till (unit 4), glaciofluvial sand (unit 3), clay till (unit 2), and lacustrine sand, silt, and clay (unit...
The embronic and larval development of the rainbow trout
A.E. Knight
1963, Transactions of the American Fisheries Society (92) 344-355
Photographs of the developing rainbow trout, Salmo gairdneri Richardson, are presented in sequence from the initial cleavage through hatching. Approximately 3,000 eggs were incubated in standard hatchery troughs supplied with spring water at a constant temperature of 54° F. Accepted fish cultural methods were followed to insure normal developmental patterns....
Reductive dechlorination of DDT to DDD by yeast
Burton J. Kallman, Austin K. Andrews
1963, Science (141) 1050-1051
Labeled DDD [ 1,1-dichlor-o-2,2-bis(p-chlorophenyl)-ethane] was formed from C14-labeled DDT in the presence of yeast. The formation of DDD from DDE [1,1-dichloro-2,2-bis (p-chlorophenyl)-ethylene] was not observed, indicating that a reductive dechlorination of DDT occurs....
Sinuosity of alluvial rivers on the great plains
S. A. Schumm
1963, Geological Society of America Bulletin (74) 1089-1100
Data on the morphologic and sediment characteristics of stable alluvial rivers of the Great Plains were collected at 50 cross sections. The channel patterns of these rivers were classified into five types: tortuous, irregular, regular, transitional, and straight. Because no clear demarcation existed between each of the types, the pattern of the rivers was...
Origin of some intermittent ponds on quartzite ridges in western North Carolina
John C. Reed Jr., Bruce H. Bryant, John T. Hack
1963, Geological Society of America Bulletin (74) 1183-1188
Several intermittent ponds and closed depressions as much as 200 feet wide occur on the crests of ridges in gently dipping Cambrian(?) quartzites in the southeastern foothills of the Blue Ridge Mountains near Morganton, North Carolina. The unconsolidated fill and debris in the ponds consists of clayey sand and saprolite with accessory minerals that could have...
Distribution of fluorine in unaltered silicic volcanic rocks of the western conterminous United States
R.R. Coats, W.D. Gross, L. F. Rader Jr.
1963, Economic Geology (58) 941-951
An investigation of more than 170 samples of glass-rich volcanic rocks of rhyolitic or rhyodacitic composition shows marked regional variations in the fluorine content. The uniformity of the class of rocks was controlled by index of refraction determinations on fused beads and by chemical analyses of about one-seventh of the total number. The fluorine content...
Hypervelocity impact of steel into Coconino Sandstone
Eugene Merle Shoemaker, D. E. Gault, H. J. Moore, R. V. Lugn
1963, American Journal of Science (261) 668-682
Impact of a 0.4019-g steel sphere at 4.27 km/sec into Coconino Sandstone [Permian] from Meteor Crater, Arizona, produced a crater 11-12 cm across and 2.45 cm deep. The ejecta consist of sandstone fragments, disaggregated sand, splinters of sand...
The hydraulic geometry of a shallow estuary
W. B. Langbein
1963, International Association of Scientific Hydrology - Bulletin (8) 84-94
An analogy with entropy production in steady-state systems leads to a statement that the geometry of natural waterways is governed by two opposing influences: a) equal work per unit of area of bed, and b) minimum work done in the system as a whole. The resulting calculations applied to shallow, estuaries are verified...
Preliminary results of a study of calcium carbonate saturation of ground water in central Florida
William Back
1963, International Association of Scientific Hydrology - Bulletin (8) 43-51
The departure of ground water from equilibrium with calcite is being studied in central Florida. Measurements of pH, temperature, and concentration of bicarbonate made in the field are used with standard laboratory analyses of water samples to calculate an ion activity product (K) for calcium carbonate. The calculated Kiap is compared with the...
Correlations and problems in belt series stratigraphy, Northern idaho and western Montana
J. E. Harrison, A.B. Campbell
1963, Geological Society of America Bulletin (74) 1413-1427
A continuous strip of geologic maps has recently been completed along the Idaho-Montana state line between Clark Fork, Idaho, and Superior, Montana. New stratigraphic and petrographic information provides the basis for stratigraphic correlations and for the interpretation of facies changes in this part of the basin of deposition of the Precambrian Belt <span...
