Delayed molt of primary feathers of mourning doves during winter
J.W. Ault, V.J. Heller, J. C. Lewis, J.A. Morrison
1976, Journal of Wildlife Management (40) 184-187
During a study of the ecology of mourning doves (Zenaida macroura) in Jackson County, southwestern Oklahoma, we noted (Morrison and Lewis 1974) that the post juvenal molt of primary feathers progressed at a slower rate than is described in the literature (Jenkins 1955:23, Swank 1955, Southeastern Association of Game and...
Thermal effects on fish ecology
Charles C. Coutant
1976, Book chapter, Encyclopedia of Environmental Science and Engineering
Of all the environmental factors that influence aquatic organisms, temperature is the most all-pervasive. There is always an environmental temperature while other factors may or may not be present to exert their effects. Fish are, for all practical purposes, thermal conformers, or obligate poikilotherms. That is, they are able to...

This map and accompanying table show Hydrologic Units that are basically hydrographic in nature. The Cataloging Units shown will supplant the Cataloging Units previously used by the U.S. Geological Survey in its Catalog of Informaiton on Water Data (1966-72). The previous U.S. Geological Survey Catalog-Indexing System was by map number...

Selected hydrologic data, Chester County, Pennsylvania
Laurence J. McGreevy, Ronald A. Sloto
1976, Report
This report presents selected hydrologic data collected during a study of the ground-water resources of Chester County, Pennsylvania. The study was made during 1973-76 by the U. S. Geological Survey in cooperation with the Chester County Water Resources Authority. This report is intended to make the data conveniently available and...

Populations of the planet-crossing asteroids
Eugene Merle Shoemaker, E. F. Helin, S. L. Gillett
1976, Geologica Romana (15) 487-489
The population of Apollo, Amor and Mars crossing asteroids is studied. With the 18-inch Schmidt camera of the Hale Observatories at Mt. Palomar, four new planet crossing asteroids were discovered. A formal theory relating the probability of discovery of asteroid of a given orbital class to condition of search has...

Flood frequency of Mississippi streams
B.E. Colson, James W. Hudson
1976, Report
Techniques have been developed for estimating future flood magnitudes having recurrence intervals as great as 100 years. Estimates for gaged sites were obtained by application of the log-Pearson Type III frequency distribution. Estimates for ungaged sites are defined by mathematical relations which may be solved using data from topographic maps....

Geothermal handbook
1976, FWS/OBS 76/36
The Bureau of Land Management offered over 400,000 hectares (one million acres) for geothermal exploration and development in 1975, and figure is expected to double this year. The Energy Research and Development Administration hopes for 10-15,000 megawatts of geothermal energy by 1985, which would require, leasing over 16.3 million hectares...
Textural variation within Great Salt Lake algal mounds
Robert B. Halley
1976, Book chapter, Stromatolites
This chapter discusses textural variation within the Great Salt Lake algal mounds. Great Salt Lake algal mounds contain: (1) a framework of non-skeletal, algally induced aragonite precipitates; (2) internal sediment; and (3) inorganic cement. These three elements create a variety of laminated, poorly laminated, and unlaminated internal textures. Interior framework...

Myxosoma cerebralis: In vitro sporulation of the Myxosporidan of salmonid whirling disease
K. Wolf, M.E. Markiw
1976, Journal of Protozoology (23) 425-427
Trophozoites and other pre-spore stages of the myxosporidan Myxosoma cerebralis were taken from infected rainbow trout (Salmo gairdneri) and cultured in vitro. Cultures eventually yielded mature spores capable of discharging their polar capsules. This is the first report of culture of a myxosporidan....
Vitamin E and selenium interrelations in the diet of Atlantic salmon (Salmo salar): Gross, histological and biochemical deficiency signs
Hugh A. Poston, G. F. Combs Jr., Louis Leibovitz
1976, Journal of Nutrition (106) 892-904
Either simultaneous or separate dietary deficiencies of vitamin E and selenium in Atlantic salmon during first 4 weeks of feeding caused twice the mortality shown in fish fed both supplemental vitamin E (0.5 IU/g dry diet) and selenium (0.1 µg/g). Subsequent dietary repletion with both vitamin E and selenium significantly...

1976, Journal of the Fisheries Research Board of Canada (33) 1197-1198
Experiments conducted simultaneously at two laboratories have shown brook trout (Salvelinus fontinalis) egg transmission of the virus of infectious pancreatic necrosis with eggs treated with 100 ppm iodine (as Wescodyne®) and with nontreated eggs....
Glomerular mesangial fibrosis in hatchery-reared rainbow trout (Salmo gairdneri)
D.E. Hinton, R.T. Jones, R. L. Herman
1976, Journal of the Fisheries Research Board of Canada (33) 2551-2559
Light and electron microscopic studies were performed on tissues of hatchery-reared rainbow trout (Salmo gairdneri) having a disease of currently unknown etiology with external symptoms of severe edema which causes increased mortality rate. Comparison with unaffected trout tissues revealed loss of cellularity in glomerular tufts with a replacement of mesangial...
