Distribution of rubidium between sodic sanidine and natural silicic liquid
D. C. Noble, C. E. Hedge
1970, Contributions to Mineralogy and Petrology (29) 234-241
Phenocrysts of sodic sanidine from twelve upper Cenozoic units of silicic ash-flow tuff and lava from the Western United States contain from 0.25 to 0.45 the Rb present in the associated groundmass materials. The ratios of potassium to rubidium in the sanidines are, on the average,...

Head-scratching method of the Swainson's warbler
Brooke Meanley
1970, The Auk (87) 163-163
Ficken and Ficken (Auk, 85: 136, 1968) suggest that the "Head-scratching method may prove a valuable addition to the set of complex characters that can be used in defining genera," and that field observers should continue to fill gaps in our knowledge of this behavior. In the course of a...
Passive immunization of pigeons against trichomoniasis
R. M. Kocan
1970, Journal of Protozoology (17) 551-553
Nonimmune homing pigeons Columba livia were infected with the Jones' Barn strain of Trichomonas gallinae and subsequently transfused with plasma from acute or chronically infected pigeons harboring one of 3 different strains of T. gallinae. The transfusions were either a single 2 ml dose given one day after inoculation or three 1 ml doses given 0,...
Soil-food chain-pesticide wildlife relationships in aldrin-treated fields
L.J. Korschgen
1970, Journal of Wildlife Management (34) 186-199
Soil-food-chain-pesticide wildlife relationships were investigated to learn the concentration of pesticide residues present in soils, macro-invertebrates, vertebrates, and seeds as a result of annual applications of aldrin at recommended rates for pest control. Two central Missouri cornfields treated with aldrin at 1 lb/acre, for 16 and 15 of the past...
Bronzed cowbird taken in Florida
R.E. Matteson
1970, The Auk (87) 588-588
On 8 November 1968 in Gainesville, Florida, I removed a male Bronzed Cowbird (Tangavius a. aeneus) from a blackbird decoy trap containing a large number of Brown-headed Cowbirds (Malothrus ater). Oliver L. Austin, Jr., at the Florida State Museum, verified the species identification by noting the notched inner webs of...
Organochlorine insecticide residues in soils and soil invertebrates from agricultural lands
C.D. Gish
1970, Pesticides Monitoring Journal (3) 241-252
Soils and earthworms and other soil invertebrates were collected from 67 agricultural fields in eight States. Samples were analyzed by gas chromatography for DDE, DDD, DDT, aldrin, dieldrin, endrin, heptachlor, heptachlor epoxide, and gamma-chlordane insecticides. Organochlorine insecticides in soils averaged 1.5 ppm, dry weight, and in earthworms, 13.8...
Toxicity of DDT to Japanese quail as influenced by body weight, breeding condition, and sex
C.D. Gish, N.J. Chura
1970, Toxicology and Applied Pharmacology (17) 740-751
Controlled experiments were utilized to simulate the stresses on wild birds of breeding condition and of weight loss due to migration. Light conditions in the laboratory were manipulated to produce Japanese quail (Coturnix coturnix japonica) in breeding condition and not in breeding condition. Within each of these groups, some birds...
Molt and taxonomy of red-breasted nuthatches
Richard C. Banks
1970, The Wilson Bulletin (82) 201-205
The postnuptial and postjuvenal molts of Red-breasted Nuthatches occur from middle June to late September. Some birds may be nearly finished with the complete molt before other individuals begin, so that specimens taken at any given time may differ by as much as two months in the age of their...
Surfactants as blackbird stressing agents
P.W. Lefebvre, J.L. Seubert
1970, Proceedings of the Vertebrate Pest Conference (4) 156-161
Applications of wetting-agent solutions produce mortality in birds. The exact cause of death is undetermined but it is believed that destruction of the insulating qualities of the plumage permits ambient cold temperatures and evaporation to lower the body temperature to a lethal level. The original concept of using these materials...
Two species of Simuliidae (Diptera), Cnephia ornithophilia and Prosimulium vernale, from Maryland
I.B. Tarshis, J.N. Stuht
1970, Annals of the Entomological Society of America (63) 587-590
The finding of Cnephia ornithophilia Davies, Peterson, & Wood and Prosimulium vernale Shewell for the first time at the Patuxent Wildlife Research Center, Laurel, Maryland, is described. Larvae of C. ornithophilia were collected Nov. 15, pupae Feb. 14, and adult flies Feb. 28. No immature or adult specimens were found between Apr. 2 and Nov. 14....

The thin eggshell problem

J.W. Gillett, editor(s)
1970, Book chapter, Proceedings of the symposium, the biological impact of pesticides in the environment
It has long been known that DDT and related chemicals can impair the reproduction of birds. In early years of organochlorine pesticide use, widespread mortality occurred immediately following heavy applications of these chemicals, and survivors contained substantial amounts of toxicant in their tissues. Repopulation from untreated areas tended...
DDE and DDD residues correlated with mortality of experimental birds

1970, Conference Paper, Pesticides symposia: Collection of papers presented at the 6th -7th Inter-American Conferences on Toxicology and Occupational Medicine, University of Miami School of Medicine, Miami
Nearly everywhere in nature are found DDE and DDD, which are metabolites of DDT, and they often become concentrated through food chains. DDD is also a commercial insecticide. large amounts of both are frequently found in birds, but the significance of these amounts has puzzled many owrkers. Studies at Clear...

A proposed streamflow data program for Ohio
Peter W. Anttila
1970, Open-File Report 70-10
A streamflow data program is proposed for Ohio which consists of both data collection and data analysis. The program is proposed after a study which (1) established long-term objectives and goals for streamflow information, (2) examined and analyzed available data to determine its adequacy for meeting the established goals, and...
Buldir Depression - A Late Tertiary graben on the Aleutian Ridge, Alaska
M. S. Marlow, D.W. Scholl, E. C. Buffington, R.E. Boyce, T. R. Alpha, P.J. Smith, C.J. Shipek
1970, Marine Geology (8) 85-108
Buldir Depression is a large, rectilinear basin that lies on the northern edge of the Aleutian Ridge and is aligned with the arcuate chain of active volcanoes on the ridge crest. The depression appears to be a volcanic-tectonic feature, which began to form...
Earthquakes induced by fluid injection and explosion
J. H. Healy, R. M. Hamilton, C.B. Raleigh
1970, Tectonophysics (9) 205-214
Earthquakes generated by fluid injection near Denver, Colorado, are compared with earthquakes triggered by nuclear explosion at the Nevada Test Site. Spatial distributions of the earthquakes in both cases are compatible with the hypothesis that variation of fluid pressure in preexisting fractures controls...

Coastal currents and mass transport of surface sediments over the shelf regions of Monterey Bay, California
Stephen C. Wolf
1970, Marine Geology (8) 321-336
In Monterey Bay, the highest concentrations of medium and fine sands occur nearshore between ten and thirty fathoms. Silt and clay accumulate in greater depths. Contours of median diameter roughly parallel the isobaths.Fine-grained materials are supplied to the bay region from erosion of cliffs which partly surround Monterey Bay, from...

D.W. Scholl, E. C. Buffington, D.M. Hopkins, T. R. Alpha
1970, Marine Geology (8) 187-210
Three exceptionally large and long submarine canyons — Bering, Pribilof, and Zhemchug — incise the continental slope underlying the southeastern Bering Sea. Bering Canyon, the world's longest known slope valley, is approximately 400 km long and has a volume of 4,300 km3. The volume of Pribilof Canyon is 1,300 km3 and...
Rapid changes in the head of the Rio Balsas Submarine Canyon system, Mexico
E. Reimnitz, M. Gutierrez-Estrada
1970, Marine Geology (8) 245-258
The investigation of a river delta and the heads of several nearby submarine canyons in western Mexico produced evidence for rapid changes in the configuration and depth of the nearshore portions of canyon tributaries. General scarcity of data on the rates of submarine...
Development of the Astoria Canyon-Fan physiography and comparison with similar systems
C.H. Nelson, P.R. Carlson, J.V. Byrne, T. R. Alpha
1970, Marine Geology (8) 259-291
A detailed bathymetric study of Astoria Canyon and Astoria Fan provides a model for typical submarine canyon-fan systems. The present canyon head is 9 miles (17 km) west of the Columbia River mouth but buried Pleistocene channels appear to have connected the two features in the past. The canyon, which...
