Some helminth parasites of the American bald eagle
A.A. Kocan, L. N. Locke
1974, Journal of Wildlife Diseases (10) 8-10
Bald eagles (Haliaeetus leucocephalus) found dead or moribund in the United States and Canada and submitted to Patuxent Wildlife Research Center were examined for helminth parasites. Nine genera of helminths were reported which include new host records for Clinostomum complanatum, Neogogatea pandionis, Centrorhynchus sp., Serratospiculum amaculata, Capillaria contorta, and Habronema americanum....
Seismic risk maps
David M. Perkins
Robert Mallis, editor(s)
1974, Earthquake Information Bulletin (USGS) (6) 10-15
What is the possibility that an earthquake will occur near you? Have you ever wondered what the chances were that an earthquake could affect you at home or at work? Perhaps you are planning to move to a part of the country subject to frequent earthquakes. How do you determine...
Myxosoma cerebralis: Comparative sensitivity of spore detection methods
M.E. Markiw, K. Wolf
1974, Journal of the Fisheries Research Board of Canada (31) 1597-1600
Physical and biophysical methods of detecting spores of Myxosoma cerebralis were used in sequence on 87 individual fingerling rainbow trout (Salmo gairdneri) from two populations with a low incidence of infection. Physical methods of releasing spores from the organs of equilibrium, gill arches, or the axial skeleton gave an estimated rate of...
Preliminary map showing availability of ground water from major glacial-drift aquifers in Griggs and Steele Counties, North Dakota
Joe S. Downey
1974, Open-File Report 74-1023
This investigation is part of a statewide program to determine the location, extent, and hydrologic characteristics of the ground-water reservoirs (aquifers).The investigation was made cooperatively by the U.S. Geological Survey, North Dakota State Water Commission, North Dakota Geological Survey, and Griggs and Steele Counties Water Management Districts.This preliminary map is...
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...
The sea lamprey and its control
R. Saalfeld, J.H. Howell
1974, Book chapter, Michigan Fisheries Centennial Report, 1873-1973, No. 6

Hydrologic data for Little Elm Creek, Trinity River Basin, Texas, 1972
B.B. Hampton
1974, Report
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...
Earthquakes, January-February 1974
W. J. Person
1974, Earthquake Information Bulletin (USGS) (6) 18-19
During the first 2 months of 1974, earthquakes caused fatalities in Peru and Turkey. The largest earthquake during the period was a magnitude 7.2 shock in the New Hebrides Islands. A local tsunami was generated by a magnitude 7.0 earthquake in the Solomon Islands. The relative quiet that characterized world...
Teleseismic studies indicate existence of deep magma chamber below Yellowstone National Park
H. M. Iyer
1974, Earthquake Information Bulletin (USGS) (6) 3-7
The secrets of Yellowstone National Park's spectacular geysers and other hot water and steam phenomena are being explored by the U.S Geological Survey with the aid of distant earthquakes (teleseisms). For some time geologists have known that the remarkable array of steam and hot water displays, for which the park...
Relationships between chemical structure and rat repellency. II. Compounds screened between 1950 and 1960
W.A. Bowles, V. A. Adomaitis, J.B. DeWitt, J.J. Pratt Jr.
1974, Report
Over 4,600 compounds, chiefly organic types, were evaluated using both a food acceptance test (Part A) and a barrier penetration bioassay (Part B), to correlate relationships between chemical structure and rodent repellency.These chemicals are indexed and classified according to the functional groups present and to the degree of substitution within...
