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...

Recoveries of banded Laysan albatrosses (Diomedea immutabilis) and black-footed albatrosses (D. nigripes)
C.S. Robbins, D.W. Rice
Warren B. King, editor(s)
1974, Book chapter, Pelagic Studies of Seabirds in the Central and Eastern Pacific Ocean
Summarizes the seasonal distribution of pelagic recoveries of 324 banded Laysan Albatrosses and 399 banded Black-footed Albatrosses. Different age groups of each species concentrate in somewhat different areas, and, although range overlap between species is almost complete, each has its own distinctive seasonal distribution pattern....
Monitoring bird population trends
C.S. Robbins
John P. Slusher, Thomas M. Hinckley, editor(s)
1974, Book chapter, Timber-Wildlife Management Symposium Proceedings.
The Breeding Bird Survey monitors annually the breeding populations of nearly 500 bird species by means of 2,000 random roadside counts of fifty 3-minute stops each. Results are computer-analyzed by State and Province, physiographic and geographic regions, and for the entire continent. Short- and long-term population changes are...
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...
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...
