Testing of selected pharmacological agents for capturing waterfowl [Annual Progress Report]
D. W. Cline
1970, Report
The response of game-farm mallards (Frost strain) to seven pharmacological immobilizing agents was evaluated in Phase I of a planned four-phase study. A limited amount of testing was also done with wild mallards. Single dosages were administered to determine the mean effective dose (ED50) and mean lethal dose (LD50), The...
Extreme female predominance in the bloater (Coregonus hoyi) of Lake Michigan in the 1960's
Edward H. Brown Jr.
C.C. Lindsey, C.S. Woods, editor(s)
1970, Book chapter, Biology of coregonid fishes
The sex composition and other biological characteristics of the bloater changed substantially during recent decades of continuous ecological change in Lake Michigan. The percentages of females increased from 72% of the bloaters samples in 1928-32 to 95% in 1963, and ranged from 94 to 97% in 1964-69. The unusual predominance...

Temperature tolerance of young-of-the-year cisco, Coregonus artedii
Thomas A. Edsall, Peter J. Colby
1970, Transactions of the American Fisheries Society (99) 526-531
Young-of-the-year ciscoes (Coregonus artedii) acclimated to 2, 5, 10, 20 and 25 C and tested for tolerance to high and low temperatures provide the first detailed description of the thermal tolerance of coregonids in North America. The upper ultimate lethal temperature of the young ciscoes was 26 C (6 C...
Resource crises in Lake Erie
Wilbur L. Hartman
1970, Explorer (12) 6-11
Despite the tremendous value of the Great Lakes, a malaise is seriously destroying their worth. Accelerated enrichment, unabated pollution, over-exploitation, and accidental and intentional introduction of exotic species, have all been guided--more often misguided--by man. Of all five Great Lakes, Lake Erie stands out as the one most...

New homes for prairie ducks
Harold A. Doty
1970, Report
This pamphlet describes how to make, install and care for inexpensive duck nesting baskets. Ducks have been attracted to these structures in the prairies of eastern North and South Dakota, western Minnesota, and northern Iowa. Nesting structures can help increase the number of local nesting ducks, especially mallards....

The demography of the lizard, Uta stansburiana Baird and Girard, in southern Nevada
F.B. Turner, G.A. Hoddenbach, P.A. Medica, J.R. Lannom Jr.
1970, Journal of Animal Ecology (39) 505-519
Between 1966 and 1967 populations of Uta stansburiana in southern Nevada increased about 40%. Over the next year they declined by about 50%. These changes are explained in terms of annual differences in fecundity and survival. Most females laid five clutches of...

Body-scale relation and calculation of growth in fishes
Ralph Hile
1970, Transactions of the American Fisheries Society (99) 468-474
Most calculations of fish growth from scale measurements are made from one of four types of curves: straight line through the origin (Dahl-Lea); straight line with intercept (Lee); logarithmic line (Monastyrsky); empirically derived curve (SegerstråYle). Occasionally, different curves are used for different length intervals of fish. Present understanding of the...
Pesticide concentrations in Great Lakes fish

During the past 4 years the Ann Arbor Great Lakes Fishery Laboratory of the Bureau of Commercial Fisheries has been monitoring insecticide levels in fish from the Great Lakes. The two insecticides found in all Great Lakes fish have been DDT (DDT, DDD, DDE) and dieldrin. Fish from Lake Michigan...

Fine, euhedral crystals of troilite from lunar sample 10050 show a hexagonal habit consistent with the high-temperature NiAs-type structure. Complete three-dimensional counter intensity data have been measured and used to confirm and refine Bertaut's proposed low-temperature crystal structure....
Brines and interstitial brackish water in drill cores from the deep gulf of Mexico
F.T. Manheim, F.L. Sayles
1970, Science (170) 57-61
Marked increases in interstitial salinity occur in two drill holes located in the Gulf of Mexico at a water depth of more than 3500 meters. The increases probably arose through diffusion of salt from buried evaporites. In one hole, however, brackish water was encountered on penetrating the oil-permeated cap rock...

1970, Science (168) 659-663
The Tektite experiment was designed to provide data for a number of behavioral, biomedical, and engineering studies in addition to the marine sciences program. Conditions for some of these studies were not altogether compatible with the program for the marine sciences. For example, isolation imposed by human behavioral studies precluded...
