Publication Extents

Not all publications have extents, not all extents are completely accurate
Biological Laboratory, Ann Arbor, Michigan
James W. Moffett
1963, American Zoologist (3) 374-375
This laboratory located about 40 miles west of Detroit, near the intersection of highways I-94 and US-23, can be reached by bus, railroad, or via commercial airlines to Detroit Willow Run or Metropolitan airports. Field biological stations are located in Wisconsin at Ashland; in Ohio at Sandusky; and in Michigan...
Labeling lake water with tritium
B. J. Frederick
1963, International Journal of Applied Radiation and Isotopes (14) 401-404
A method of packaging tritiated water in a manner that facilitates safe handling in environmental labeling operations, and procedures followed in labeling a large body of water with a small volume of tritiated water are described....
Indirect spectrophotometric determination of traces of bromide in water
M. J. Fishman, M. W. Skougstad
1963, Analytical Chemistry (35) 146-149
A rapid, accurate, and sensitive indirect spectrophotometric method for the determination of bromide in natural waters is based on the catalytic effect of bromide on the oxidation of iodine to iodate by potassium permanganate in sulfuric acid solution. The method is applicable to concentrations ranging from 1 to 100 μg....
Tellurium: A new sensitive test
H. W. Lakin, C. E. Thompson
1963, Science (141) 42-43
A new, extremely sensitive method for the quantitative determination of tellurium is based on the induced precipitation of elemental gold from a 6N HCl solution containing gold chloride, cupric chloride, and hypophosphorous acid; the amount of gold reduced is proportional to the amount of tellurium present. As little as 1...
Spectrophotometric determination of micro quantities of zinc in rocks
C. Huffman Jr., H. H. Lipp, L. F. Rader
1963, Geochimica et Cosmochimica Acta (27) 209-215
A chemical method is presented for the determination of microgram amounts of zinc in rocks. Zinc is absorbed on anion-exchange resin from 1.2 M hydrochloric acid and eluted with 0.01 M hydrochloric acid. A diethyldithiocarbamate separation removes traces of interfering elements from the eluate. The zinc-diethyldithiocarbamate complex is extracted into...
Some phases of the life history of the trout-perch
John L. Magnuson, Lloyd L. Smith
1963, Ecology (44) 83-95
The trout-perch, Percopsis omiscomaycus (Walbaum), is one of the more abundant forage fishes in the larger lakes of midwestern United States and central Canada where walleye, Stizostedion v. vitreum (Mitchill), yellow perch, Perca flavescens (Mitchill), and coregonids predominate. It has been suggested that it may have considerable effect on...
The movements of walleyes tagged as yearlings in Lake Erie
David R. Wolfert
1963, Transactions of the American Fisheries Society (92) 414-420
A total of 3,998 yearling walleyes, Stizostedion vitreum vitreum (Mitchill), were captured, tagged, and released along the south shore of western Lake Erie to determine their movements and their dispersal from a known nursery area. Four hundred ninety-nine recoveries were made over a period of 3 years. Tagged walleyes traveled...
Selected hydrologic data, Tooele Valley, Tooele County, Utah
Joseph S. Gates
1963, Utah Basic-Data Report 7
This report is intended to serve two purposes: (1) to make available to the public basic ground-water data useful in planning and studying development of water resources, and (2) to supplement an interpretive report that will be published later.Records were collected during the period 1958-63 by the U.S. Geological Survey...
Selected hydrologic data, Jordan Valley, Salt Lake County, Utah
I. Wendell Marine, Don Price
1963, Utah Basic-Data Report 4
This report is intended to serve two purposes: (1) to make available to the public basic ground-water data useful in planning and studying development of water resources and (2) to supplement an interpretive report that will be published later.Records were collected during the period 1956-59 by the U.S. Geological Survey...
Ground-water data, central Sevier Valley, parts of Sanpete, Sevier, and Piute Counties, Utah
Carl H. Carpenter, Richard A. Young
1963, Utah Basic-Data Report 3
This report is intended to serve two purposes: (1) to make available to the public basic ground-water data useful in planning and studying development of water resources and (2) to supplement an interpretive report that will be published later.Records were collected during the period 1956-60 by the U.S. Geological Survey...
Selected hydrologic data, Pavant Valley, Millard County, Utah
Reed W. Mower
1963, Utah Basic-Data Report 5
This report is intended to serve two purposes: (1) to make available to the public basic ground-water data useful in planning and studying development of water resources and (2) to supplement an interpretive report that will be published later.Records were collected during the period 1959-62 by the U.S. Geological Survey...
Hydrology of upper Black Earth Creek basin, Wisconsin, with a section on surface water
Denzel R. Cline, Mark W. Busby
1963, Water Supply Paper 1669-C
The upper Black Earth Creek drainage basin has an area of 46 square miles and is in Dane County in south-central Wisconsin. The oldest rock exposed in the valley walls is the sandstone of Late Cambrian age. Dolomite of the Prairie du Chien Group of Ordovician age overlies the sandstone...
Simple measurements of morphological changes in river channels and hillslopes
J.P. Miller, Luna Bergere Leopold
1963, Conference Paper
One of the principal types of observational evidence on climatic changes in the recent geologic past is in river position and elevation. It is well known that river channels, particularly those flowing through alluvium or on relatively soft bedrock, tend to develop flood plains by lateral migration of the channel....
The movement, heterogeneity, and rate of exploitation of walleyes in northern Green Bay, Lake Michigan, as determined by tagging
Walter R. Crowe, Ernest G. Karvelis, Leonard S. Joeris
1963, Conference Paper, Proceedings of the North Atlantic Fish Marking Symposium
The Michigan waters of northern Green Bay are an important center for commercial and sport fishing. This 400-square-mile area has supported a commercial fishery for many years but the development of the intensive sport fishery is more recent, mostly since World War II. The commercial fishery is based on several...
Quantitation of microorganic compounds in waters of the Great Lakes by adsorption on activated carbon
Stacy L. Daniels, Lloyd L. Kempe, E. S. Graham, Alfred M. Beeton
1963, Conference Paper, Proceedings of the 6th Conference on Great Lakes Research
Microorganic compounds in waters of Lakes Michigan and Huron have been sampled by adsorption on activated carbon in filters installed aboard the M/V Cisco and at the Hammond Bay Laboratory of the U.S. Bureau of Commercial Fisheries. The organic compounds were eluted from the carbon according to techniques developed at the U.S....
Conversations on ecology IV
Luna Bergere Leopold
1963, The Garden Journal: Journal of the New York Botanical Garden (13) 141-142
The conversations on ecology have mentioned the pesticide problem, and in such discussion it is easy to lose sight of the basic philosophic view which is an undercurrent in Miss Carson's book. I should like to expand on that philosophic premise and examine some of its implications for planning vegetation...
