1974, Acta Ornithologica (14) 446-458
A two-year Breeding Bird Atlas program for Montgomery County was undertaken by the Maryland Ornithological Society in 1971-1972. The county was divided into 65 5 km blocks and each block was assigned to an observer. Preliminary results show 46 to 93 species (mean 66) recorded per 5 km...
Percutaneous absorption of several chemicals, some pesticides included, in the red-winged blackbird
J.G. Rogers Jr., R.H. Cagan, M.R. Kare
1974, Environmental Physiology and Biochemistry (4) 104-111
Percutaneous absorption in vivo through the skin of the feet of the red-winged blackbird (Agelaius phoeniceus) has been investigated. Absorption after 18-24 hours exposure to 0.01 M solutions of salicylic acid, caffeine, urea, 2,4-D, dieldrin, diethylstilbesterol, and DDT was measured. Of these, only DDT and diethylstilbesterol were not...

Relationships between chemical structure and rat repellency: II. compounds screened between 1950 and 1960
Walter A. Bowles, V. A. Adomaitis, J.B. DeWitt, J.J. Pratt Jr.
1974, Technical Report 75-11-FEL.
Over 4,600 compounds, chiefly organic types, were evaluated using both a food acceptance test (Part A) and a barrier penetration bioassay (Part B), to correlate relationships between chemical structure and rodent repellency. These chemicals are indexed and classified according to the functional groups present and to the degree of substitution...

Optimal exploitation strategies for an animal population in a stochastic serially correlated environment
David R. Anderson
1974, Book
Optimal exploitation strategies were studied for an animal population in a stochastic, serially correlated environment. This is a general case and encompasses a number of important cases as simplifications. Data on the mallard (Anas platyrhynchos) were used to explore the exploitation strategies and test several hypotheses because relatively...
The National Center of the U.S. Geological Survey
Water Resources Division, U.S. Geological Survey
1974, Report
In August of 1973, the U. S. Geological Survey moved its first group of employees into the John Wesley Powell Federal Building of its newly constructed National Center at Reston, Virginia. The move signaled the fruition of more than a decade of planning and work to consolidate the agency's widespread...
An Anvilian (early pleistocene) marine fauna from western Seward Peninsula, Alaska
D.M. Hopkins, R.W. Rowland, R.E. Echols, P. C. Valentine
1974, Quaternary Research (4) 441-470
Cover sediments of the York Terrace exposed near the California River, western Seward Peninsula, Alaska, yield mollusks, ostracodes, and foraminifera that lived during the Anvilian transgression of early Pleistocene age. The fossiliferous sediments lie at the inner edge of the York Terrace, a...
Quaternary deposits in southwestern Afghanistan
G.I. Smith
1974, Quaternary Research (4) 39-52
Geologic evidence in the closed Seistan Basin of southwestern Afghanistan and adjacent parts of Iran and Pakistan indicates that a lake as much as 65,000 sq km in size occupied this closed depression during Pleistocene time. The deposits consist mostly of lacustrine silt and clay and have a maximum observed...
Thin and layered subcontinental crust of the Great Basin western North America inherited from Paleozoic marginal ocean basins?
Michael Churkin Jr., E.H. McKee
1974, Tectonophysics (23) 1-15
The seismic profile of the crust of the northern part of the Basin and Range province by its thinness and layering is intermediate between typical continental and oceanic crust and resembles that of marginal ocean basins, especially those with thick sedimentary fill. The...
Preliminary results from a search for regional tectonomagnetic effects in California and western Nevada
M.J.S. Johnston
1974, Tectonophysics (23) 267-275
Physical theory and laboratory experiments both indicate that tectonomagnetic effects in seismically active areas should be detected with highly sensitive drift-free differential magnetometers. By using a pair of synchronized 0.25 7 absolute magnetometers to measure precisely field differences between 70 adjacent sites with...
Structure and development of the southern Moroccan continental shelf
William P. Dillon
1974, Marine Geology (16) 121-143
The structure of the continental shelf off southern Morocco was studied by means of 2,100 km of seismic reflection profiles, magnetic and bathymetric surveys, and dredge samples. The research area lies off four geologic divisions adjacent to the coast: the Atlas Mountains; the...
Bimodal tholeiitic-dacitic magmatism and the Early Precambrian crust
F. Barker, Z. E. Peterman
1974, Precambrian Research (1) 1-12
Interlayered plagioclase-quartz gneisses and amphibolites from 2.7 to more than 3.6 b.y. old form much of the basement underlying Precambrian greenstone belts of the world; they are especially well-developed and preserved in the Transvaal and Rhodesian cratons. We postulate that these basement rocks are largely a metamorphosed, volcanic, bimodal suite...
Geodimeter measurements of slip and strain accumulation along the San Andreas fault
J.C. Savage, W.H. Prescott
1974, Tectonophysics (23) 407-418
The U.S. Geological Survey conducts repeated geodimeter surveys of trilateration networks in central California in order to study the processes of slip and strain accumulation along the San Andreas fault. The precision of distance measurement is described by a standard deviation <span id="MathJax-Element-1-Frame"...

This report is one of a series of 37 reports presenting records of stage and discharge of streams, and of stage and contents of lakes and reservoirs in the United States during the 1966-70 water years; it contains the records for gaging stations and partial-record stations in the Snake River Basin. Since 1888, when...
Species and age composition of trap net catches in Lake Oahe, South Dakota, 1963-67
James A. Gabel
1974, Technical Paper 75
Twenty-seven fish species were captured in Lake Oahe with trap nets in 1963-67. The catch was dominated by eight species in order of abundance: black crappie (Pomoxis nigromaculatus), bigmouth buffalo (Ictiobus cyprinellus), white crappie (Pomoxis annularis), carp (Cyprinus carpio), river carpsucker (Carpiodes carpio), freshwater drum (Aplodinotus grunniens), smallmouth buffalo (Ictiobus...
Population trends, growth, and movement of bigmouth buffalo, Ictiobus cyprinellus, in Lake Oahe, 1963-70
Thomas E. Moen
1974, Technical Paper 78
The bigmouth buffalo, Ictiobus cyprinellus, is the most important commercial species in Lake Oahe, a reservoir in the upper Missouri River. The population was dominated by three strong year classes (1959, 1960, and 1962). Estimated population in the fall of 1964 was 540,000 fish of the combined 1959-60 year classes...
Goldeye, Hiodon alosoides, in Lake Oahe: abundance, age, growth, maturity, food, and the fishery, 1963-69
Grant L. Miller, William R. Nelson
1974, Technical Paper 79
Reproductive success was relatively consistent, and adequate to maintain species abundance at a nearly constant level, during 1963-69. Both abundance and growth in length increased from the lower to the upper portion of the reservoir. In most characteristics -- growth in length, length-weight relation, age at maturity, and food --...
