Spermatogenesis in bald eagles experimentally fed a diet containing DDT
L. N. Locke, N.J. Chura, P.A. Stewart
1966, Condor (68) 497-502
When Bald Eagles were fed DDT in the diet at the level of 10 ppm (dry weight basis) for periods of 60 and 120 days, there was no interference with spermatogenic activity. Degenerative testicular changes were produced only by levels of DDT that produced abnormal neurological signs and usually resulted...
A method of shipping live larvae of Simulium vittatum long distances (Diptera: Simuliidae)
I.B. Tarshis
1966, Annals of the Entomological Society of America (59) 866-867
During studies on the biology and ecology of black flies (Simuliidae) at the Seney National Wildlife Refuge, Seney, Michigan, and at the Patuxent Wildlife Research Center, Laurel, Maryland, larvae of 3 species of black fly (Simulium vittatum Zetterstedt, S. aureum Fries, and S. decorum Walker) were collected and transported for distances of up to 50...
Electron microscope study of Sarcocystis sp
V.H. Zeve, D.L. Price, C. M. Herman
1966, Experimental Parasitology (18) 338-346
Sarcocystis sp. obtained from wild populations of grackles, Quiscalus quiscula (Linn.), were examined to clarify the effect of the parasite on the host. Electron micrographs are presented to show areas of muscle destruction adjacent to the parasite which appear to be mechanically produced by the parasite. The microtubules within the...
Trichinosis in Maryland raccoons
D.J. Winslow, D.L. Price, R.C. Neafie, C. M. Herman
1966, Bulletin of the Wildlife Disease Association (2) 81-82
During recent studies of experimental Chagas’ disease, trichinosis was found in 2 out of a total of 44 Maryland raccoons (Procyon lotor) examined histologically following necropsy. All raccoons were trapped near the towns of Beltsville or Laurel. The raccoons found to have trichinosis were trapped in the area of the...
Bald eagle pesticide relations

Residues of DDT in brains and bodies of birds that died on dosage and in survivors
L.F. Stickel, W. H. Stickel, R. Christensen
1966, Science (151) 1549-1551
Residues of 1,1,1-trichloro-2,2-bis(p-chlorophenyl)-ethane (DDT) and 1,1-dichloro-2,2-bis(p-chlorophenyl)-ethane (DDD) in brains of cowbirds (Molothrus ater) killed by dietary dosage of DDT were similar in birds that died after various lengths of time on dosage and in birds that died of delayed effects after as much as 40 days on clean food. Residues...
Monitoring wildlife for pesticide content
E. H. Dustman
1966, National Academy of Sciences NRC Publication 1402
In May 1963, the President's Science Advisory Committee issued a report entitled Use of Pesticides.17  the President already had requested the responsible federal agencies to implement the recommendations in the report. One of these recommendations was to provide for the development and coordination of a pesticide-monitoring program conducted on a continuing...
Summary of hydrologic and physical properties of rock and soil materials, as analyzed by the hydrologic laboratory of the U.S. Geological Survey, 1948-60
D. A. Morris, A.I. Johnson
1966, Report
The Hydrologic Laboratory was established in 1948 to serve as the central laboratory for the Ground Water Branch, Water Resources Division, of the U.S. Geological Survey. During the period it has been in existence, numerous samples of rock and soil materials have been analyzed. Analysis data on samples from 42...
Geohydrologic use of lithofacies maps in glaciated areas
Wayne A. Pettyjohn, P.G. Randich
1966, Water Resources Research (2) 679-689
Subsurface conditions may differ considerably from conditions indicated by surficial geologic maps, particularly in glaciated areas. Therefore, it is advantageous to use a series of lithofacies maps as a sequence of overlays plotted on transparent paper. Such maps permit direct visual determination of the lithology and areal extent of aquifers...
Effects of the earthquake of March 27, 1964, in the Homer area, Alaska
Roger M. Waller, Kirk W. Stanley
1966, Professional Paper 542-D
The March 27, 1964, earthquake shook the Homer area for about 3 minutes. Land effects consisted of a 2- to 6-foot subsidence of the mainland and Homer Spit, one earthflow at the mouth of a canyon, several landslides on the Homer escarpment and along the sea bluffs, and minor fissuring...
Effects of the earthquake of March 27, 1964, at Valdez, Alaska
Henry Welty Coulter, Ralph R. Migliaccio
1966, Professional Paper 542-C
Valdez is situated on the seaward edge of a large outwash delta composed of a thick section of saturated silty sand and gravel. The earthquake of March 27, 1964, triggered a massive submarine slide, involving approximately 98 million cubic yards of material that destroyed the harbor facilities and nearshore installations....
Effects of the March 1964 Alaska earthquake on the hydrology of south-central Alaska
Roger M. Waller
1966, Professional Paper 544-A
The earthquake of March 27, 1964, greatly affected the hydrology of Alaska and many other parts of the world. Its far-reaching effects were recorded as water-level fluctuations in gages operated on water wells and streams. The close-in effects were even more striking, however; sediment-laden ground water erupted at the surface,...
Effects of the March 1964 Alaska earthquake on the hydrology of the Anchorage area, Alaska
Roger M. Waller
1966, Professional Paper 544-B
The Anchorage hydrologic system was greatly affected by the seismic shock. Immediate but temporary effects included increased stream discharge, seiche action on lakes, and fluctuations in ground-water levels. Generally, ground-water levels were residually lowered after the initial period of fluctuation. This lowering is attributed either to changes in the discharge...
Effects of the earthquake of March 27, 1964, in the Copper River Basin area, Alaska
Oscar J. Ferrians Jr.
1966, Professional Paper 543-E
The Copper River Basin area is in south-central Alaska and covers 17,800 square miles. It includes most of the Copper River Basin and parts of the surrounding Alaska Range and the Talkeetna, Chugach, and Wrangell Mountains. On March 27, 1964, shortly after 5:36 p.m. Alaska standard time, a great earthquake having...
Hydrology and physiography of the Salton Sea, California
W.M. Littlefield
1966, Hydrologic Atlas 222
The increased utilization of the Salton Sea and its shore for recreation, the development of residential complexes on its shore, and the encroachment of the sea into these developments have emphasized the need for a concise summary of hydrologic and physiographic information concerning the area. This report attempts to fill...
