Ice on waterfowl markers
R. J. Greenwood, W.C. Bair
1974, Wildlife Society Bulletin (2) 130-134
Wild and captive giant Canada geese (Branta canadensis maxima) and captive mallards (Anas platyrhynchos) accumulated ice on neck collars and/or nasal saddles during winter storm periods in 1971 and 1972. Weather conditions associated with icing were documented, and characteristics of icing are discussed. Severe marker icing occurred during subfreezing weather...

Habitat management considerations for prairie chickens
L.M. Kirsch
1974, Wildlife Society Bulletin (2) 124-129
Lack of nesting and brood rearing habitat appears to be the universal limiting factor for prairie chickens (Tympanuchus cupido pinnatus) throughout their range. Grasslands are essential to prairie chickens, but vary widely in quality and thus in their ability to support prairie chickens. High-quality habitat is grassland providing residual vegetation...

Earthquake history of Nevada
C. A. von Hake
1974, Earthquake Information Bulletin (USGS) (6) 26-29
Since 1852, more than 30 shocks of intensity VI or greater (Modified Mercalli scale) have occurred in western Nevada. At least three of these were classified as intensity X. In addition, seven earthquakes (intensity VI or greater) were centered in the eastern part of the State. Almost 2,000 other shocks...
Earthquake history of Nebraska
C. A. von Hake
1974, Earthquake Information Bulletin (USGS) (6) 32-33
Nebraska is in a region of moderate seismicity occasionally punctuated by rather strong earthquakes. Most of the State is seismic risk zone 1, with a small part in the southeast corner in risk zone 2. the first significant earthquake felt in Nebraska occurred in 1867, the year that statehood was...

Age, growth, sexual maturity, and food of channel catfish in central Lake Oahe, 1968-69
Victor J. Starostka, William R. Nelson
1974, Technical Paper 81
Channel catfish, Ictalurus punctatus, were collected with gill nets, trawl, and trap nets at three localities in Lake Oahe for the study of year-class strength, growth in length and weight, age composition, sexual maturity, and food. Fish were recruited to all the collection gears at age II. Relatively strong year...
An antigenic comparison between infectious hematopoietic necrosis virus (OSV strain) and the virus of haemorrhagic septicaemia of rainbow trout (Salmo gairdneri) (Denmark strain) by cross neutralization
P. E. McAllister, J. L. Fryer, K.S. Pilcher
1974, Journal of Wildlife Diseases (10) 101-103
The infectious hematopoietic necrosis virus (OSV strain) and the virus of haemorrhagic septicaemia of rainbow trout (Salmo gairdneri) (Denmark strain) were examined for possible antigenic relationship by plaque neutralization using homologous and heterologous antisera. No neutralization of either virus was observed on exposure to heterologous antiserum. This indicates that there...
Effects of stocking density and water exchange rate on growth and survival of channel catfish Ictalurus punctatus (Rafinesque) in circular tanks
Kenneth O. Allen
1974, Aquaculture (4) 29-39
Channel catfish were cultured for 177 days in circular tanks containing 1.6 m3 of water at combinations of five stocking densities (90–720 fish/m3) and five water exchange rates (2.0–0.5 h per exchange). Net yield increased as stocking density increased up to 540 fish/m3 then declined at higher densities. Mean fish weight, feed...
Hazards to animals feeding on blackbirds killed with 4-aminopyridine baits
E. W. Schafer Jr., R.B. Brunton, Norman F. Lockyer
1974, Journal of Wildlife Management (38) 424-426
Red-winged blackbirds (Agelaius phoeniceus) killed by ingesting cracked corn baits treated with 3 percent 4-aminopyridine, or by oral doses of 4-aminopyridine, were fed to canines, laboratory rats (Rattus norvegicus), black-billed magpies (Pica pica), and three species of hawks. The test animals consumed the equivalent of up to 3.4 LD50 doses...
The California geodimeter network; measuring movement along the San Andreas Fault
J.C. Savage
1974, Earthquake Information Bulletin (USGS) (6) 3-7
Following the great California earthquake of 1906 H. F. Reid, a contemporary seismologist, proposed the elastic rebound theory which in effect says that earthquake potential arises from the accumulation of elastic strain within the Earth's crust, just as the stretching of a rubberband creates the potential for violent rebound upon...
Computer systems for automatic earthquake detection
S.W. Stewart
1974, Earthquake Information Bulletin (USGS) (6) 17-21
U.S Geological Survey seismologists in Menlo park, California, are utilizing the speed, reliability, and efficiency of minicomputers to monitor seismograph stations and to automatically detect earthquakes. An earthquake detection computer system, believed to be the only one of its kind in operation, automatically reports about 90 percent of all local...

The U.S. Soil Conservation Service is actively engaged in the installation of flood- and soil-erosion reducing measures in Texas under the authority of "The Flood Control Act of 1936 and 1944" and "Watershed Protection and Flood Prevention Act" (Public Law 566), as amended. The Soil Conservation Service has found a...
