F.C. Howell, G.H. Cole, M.R. Kleindienst, Barney J. Szabo, K.P. Oakley
1972, Nature (237) 51-52
EXCAVATIONS in 1957 and 1958 at the Isimila prehistoric site, in Tanzania1, sampled Acheulian occurrences in horizons at various levels in the Isimila Beds which are approximately 18 m thick. No significant breaks were observed in the sedimentary sequence, although there are numerous local hiatuses....
Subduction zones: Not relevant to present-day problems of waste disposal
E. A. Silver
1972, Nature (239) 330-331
SUBDUCTION zones are considered to be sites of disposal for vast areas of the Earth's surface1, while new surface is generated simultaneously at rise crests2. Bostrom and Sherif3 suggest that the world's industrial and domestic waste be dumped into subduction zones at deep sea trenches to allow...
Metamorphic assemblages and the direction of flow of metamorphic fluids in four instances of serpentinization
I. Barnes, John B. Rapp, J. R. O’Neil, R.A. Sheppard, A. J. Gude III
1972, Contributions to Mineralogy and Petrology (35) 263-276
Fluids related to Serpentinization are of at least three types. The first reported (Barnes and O'Neil, 1969) is a fluid of local meteoric origin, the chemical and thermodynamic properties of which are entirely controlled by olivine, orthopyroxene, brucite, and serpentine reactions. It is a Ca+2-OH−1 type and...

A new species of warbler (Parulidae) from Puerto Rico
C. B. Kepler, K.C. Parkes
1972, The Auk (89) 1-18
The West Indies are among the best known of the world's tropical regions, and our knowledge of the distribution of indigenous land birds in the Greater Antilles has been thought to be nearly complete (Bond, 1956). The last new species from the Antilles were described in 1927, the results...
Effect of Hygromycin-B on pigeons (Columba livia) with and without Trichomonas gallinae
R. M. Kocan
1972, Avian Diseases (16) 714-717
Hygromycin-B was administered in varied quantities to pigeons harboring nonvirulent Trichomonas gallinae and to pigeons free of T. gallinae. Both groups responded identically with large yellow caseous lesions in the upper digestive tract which superficially resembled canker (trichomoniasis). No mycotic association with the lesions could be established in...

Reproductive patterns in captive American kestrels (sparrow hawks)
Richard D. Porter, Stanley N. Wiemeyer
1972, Condor (74) 46-53
Female kestrels acquired in Florida in winter as full-grown birds began laying eggs a month later than did those acquired as nestlings from northeastern United States. Egg laying dates of the two groups did not overlap in 1966 through 1968. The later nesting Florida-wintering females may have nested in captivity...

Pesticide mortality of young white-faced ibis in Texas
Edward L. Flickinger, D. L. Meeker

Food resources of the California condor
S.R. Wilbur
1972, Report
Conclusions and Recommendations: Although much of the above information is imprecise and inconclusive, it is evident that the condors foraging habitat is diminishing. Food supply probably is still adequate for free-ranging nonbreeding birds, but could become limited if current land use trends continue. Congregating condors on fewer...

SUMMARY: Polychlorinated biphenyls have become ubiquitous in the world ecosystem in quantities similar to those of DDE. Experimental studies have shown that PCBs have a toxicity to mallards, pheasants, bobwhite quail, coturnix quail, red-winged blackbirds, starlings, cowbirds, and grackles that is of the same...

Hydraulic testing of hole UA-1-HTH-1, Amchitka Island, Alaska
Wilbur C. Ballance, G.A. Dinwiddie
1972, Report
Total depth of the hole was 1,054 meters (3,458 feet) but, because of borehole erosion and bridging, only about 198 meters (650 feet) of the hole was·hydraulically tested with straddle packers. Some information was obtained on the lower part of the hole by use of the pressure recorders which are...
Channel erosion surveys along proposed TAPS route, Alaska, July 1971
Joseph M. Childers
1972, Report
The U.S. Geological Survey has the threefold responsibility along the proposed route of the Trans-Alaska Pipeline System (TAPS): to investigate possible hydroloqic hazards to the pipeline, to investigate possible impacts of the pipeline on water resources, and to develop a better understanding of Arctic hydrology. Because the proposed pipeline route...
