The white-crowned pigeon: A fruit-eating pigeon as a host for Trichomonas gallinae
R. M. Kocan, A. Sprunt IV
1971, Journal of Wildlife Diseases (7) 217-218
Trichomoniasis resulting from infection by Trichomonas gallinae was observed in 12 laboratory reared white-crowned pigeons (Columba leucocephala). A field survey of nestlings in the Florida Keys revealed a prevalence of 88% T. gallinae carriers but no evidence of trichomoniasis could be found among the wild birds....
A decade of international cooperation brings a standard seismic point of view
H. S Whitcomb Jr.
1971, Earthquake Information Bulletin (USGS) (3) 16-19
Whether in a castle in Italy, a police station in Iceland, o an abandoned gold mine in Australia, the sensitive instruments in the Worldwide Seismograph Network send a steady flow of standard earthquake records to the geophysical scientific community. They provide the raw data that make possible very precise earthquake...
Some blood chemistry values for the juvenile coho salmon (Oncorhynchus kisutch)
Gary Wedemeyer, K. Chatterton
1971, Journal of the Fisheries Research Board of Canada 606-608
Overlapping Gaussian distribution curves were resolved into normal ranges for 1800 clinical test values obtained from caudal arterial blood or plasma of more than 1000 juvenile coho salmon (Oncorhynchus kisutch) held under defined conditions of diet and temperature. Estimated normal blood chemistry ranges were bicarbonate, 9.5–12.6 mEq/liter; blood urea nitrogen (BUN),...
Results from the apollo-12 passive seismic experiment
G. Latham
1971, Earthquake Information Bulletin (USGS) (3) 4-9
The objective of the passive seismic experiment is to measure vibrations of the lunar surface produced by all natural and artificial sources of seismic energy and to use these data to deduce the internal structure and composition of the moon, the nature of forces which may cause deformation of the...
A procedure for testing the antigenicity of vaccines for immunization of fish against Furunculosis
Jamieson E. Holway, G.W. Klontz
1971, Progressive Fish-Culturist 42-44
Furnunculosis, a bacterial disease caused by Aeromonas salmonicida, is potentially one of the most devastating diseases in trout and salmon hatcheries. The disease may be controlled by three methods. The most frequently used method of control has been drug therapy. Unfortunately, the bacteria often develop resistance to the...
Periodic water- and air-temperature records for Utah streams, 1966-70
G.L. Whitaker
1971, Utah Basic-Data Release 22
Since 1967, all Geological Survey hydrographers have been instructed to observe and record the water and air temperatures at times when water-discharge measurements were being made at stream-gaging stations in Utah. The frequency of these observations generally varies from I to 5 weeks, depending upon the magnitude of the stream...

Geysers
1971, Report
A geyser is a special type of hot spring that from time to time spurts water above ground. It differs from most hot springs in having periodic eruptions separated by intervals without flow of water. The temperature of the erupting water is generally nearly at boiling for pure water (212°F...
Inland fisheries
Louella E. Cable
Sidney Shapiro, editor(s)
1971, Book chapter, Our changing fisheries
Today's inland commercial fisheries are small independent operational units widely dispersed on lakes, impoundments, and streams throughout the vast central plains. The problems of the fisheries are diverse and unique to local conditions. Inland fisheries are particularly important to the Nation in times of international conflict because they...
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...
