Some characteristics of fall migration of female woodcock
R.A. Coon, P.D. Caldwell, G.L. Storm
1976, Journal of Wildlife Management (40) 91-95
Nine female woodcock (Philohela minor) were radio-tagged in central Pennsylvania before fall migration to monitor premigratory and migratory movements. Within 15 days of departure, 5 of the birds moved 0.8 to 8.0 km from their normally used area, but the remaining 4 did not move. In 1973 five marked woodcock...
A reward band study of mallards to estimate band reporting rates
Charles J. Henny, K.P. Burnham
1976, Journal of Wildlife Management (40) 1-14
Reward bands ($10) were placed on 2,122 hatching-year mallards (Anas platyrhynchos), and an additional 11,490 received conventional bands (controls) to estimate band reporting rates. An analysis of band recoveries indicated that the reporting rate was dependent primarily upon three factors: (1) the distance banded birds were recovered from the banding...
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...
Limnological data report for the Maine Department of Environmental Protection: U.S. Geological Survey cooperative lake studies project
Derrill J. Cowing, Matthew Scott
1976, Report
The report contains physical, chemical, and biological information collected on 43 Maine lakes during the 1975 calendar year. Methods for the collection and analysis of the hydrologic data are outlined.Physical characteristics listed include drainage area, surface area, surface elevation, volume, maximum depth, mean depth, epilimnion depth, epilimnion volume, and length...
Hydrologic Unit Map - 1974, state of Montana
Water Resources Division, U.S. Geological Survey
1976, Hydrologic Unit 26
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...
Geothermal energy in the United States; Part II, Assessment of resources
D.L. Williams
1976, Earthquake Information Bulletin (USGS) (8) 18-23
Geothermal energy-from heat deep inside the Earth- is a vast potential source of power. This article is the second part of a series on geothermal energy, the first part of which was in volume 8, number 1, of the Earthquake Information Bulletin (January-February 1976). Part 1 of this series described the...
