Crane reproductive physiology and conservation
G.F. Gee
1983, Zoo Biology (2) 199-213
Some unique features of crane reproduction, management, and conservation are described. Because cranes are sexually monomorphic, sexing is difficult and must be accomplished using behavior, laparoscopy, cloacal examination, genetic techniques, or fecal steroid analysis. Although husbandry techniques for cranes are similar to those used with other nondomestic birds, a number...
SOME NEW PROCESSING TECHNIQUES FOR THE IMPERIAL VALLEY 1979 AFTERSHOCKS.
A. Gerald Brady
Chung Riley M.Lew H.S.Kovacs William D., editor(s)
1983, Conference Paper, National Bureau of Standards, Special Publication
This paper describes some of the features of the latest processing improvements that the U. S. Geological Survey (USGS) is currently applying to strong-motion accelerograms from the national network of permanent stations. At the same time it introduces the application of this processing to the set of Imperial Valley aftershocks...
The granite problem as exposed in the southern Snake Range, Nevada
D. E. Lee, E. H. Christiansen
1983, Contributions to Mineralogy and Petrology (83) 99-116
A geochemically and mineralogically diverse group of granitoids is present within an area of 900 km2 in the southern Snake Range of eastern Nevada. The granitoids exposed range in age from Jurassic through Cretaceous to Oligocene and include two calcic intrusions, two different types of two-mica granites, and aplites. The...
Two examples of earthquake- hazard reduction in southern California.
W. J. Kockelman, C.C. Campbell
1983, Earthquake Information Bulletin (USGS) (15) 216-225
Because California is seismically active, planners and decisionmakers must try to anticipate earthquake hazards there and, where possible, to reduce the hazards. Geologic and seismologic information provides the basis for the necessary plans and actions. Two examples of how such information is used are presented. The first involves assessing the...
Hydrologic and geomorphic studies of the Platte River basin
Water Resources Division, U.S. Geological Survey
1983, Professional Paper 1277
The channels of the Platte River and its major tributaries, the South Platte and North Platte Rivers in Colorado, Wyoming, and Nebraska, have undergone major changes in hydrologic regime and morphology since about 1860, when the water resources of the basin began to be developed for agricultural, municipal, and industrial...
Retention of infectious haematopoietic necrosis virus infectivity in fish tissue homogenates and fluids stored at three temperatures
J. Burke, D. Mulcahy
1983, Journal of Fish Diseases (6) 543-547
Pools of brain, kidney, spleen, liver and gut tissues from several rainbow trout, Salmo gairdneri Richardson, and whole sockeye salmon, Oncorhynchus nerka (Walbaum), fry were homogenized with a known amount of infectious haematopoietic necrosis virus (IHNV). Virus was also added to ovarian fluids and sera pooled from several rainbow trout....
The fledging of common and thick-billed murres on Middleton Island, Alaska
Scott A. Hatch
1983, Journal of Field Ornithology (54) 266-274
Three species of alcids, Common and Thick-billed murres (Uria aalge and U. lomvia) and the Razorbill (Alca torda), have post-hatching developmental patterns intermediate to precocial and semi-precocial modes (Sealy 1973). The young leave their cliff nest sites at about one quarter of adult weight and complete their growth at sea....
Selective control of common carp: Ineffectiveness of 2-(digeranylamino)-ethanol (GD-174) in pond trials
P.A. Gilderhus, R.M. Burress
1983, North American Journal of Fisheries Management (3) 61-66
The candidate piscicide, 2‐(digeranylamino)‐ethanol, (commonly known as GD‐174) was subjected to efficacy trials in ponds under a wide variety of conditions. Results of the trials were disappointing considering that laboratory tests had shown the compound to be selectively toxic to common carp (Cyprinus carpio). Results of pretreatment, on‐site toxicity tests...
Temporal patterns of seed use and availability in a guild of desert ants
Patricia Mehlhop, Norman J. Scott Jr.
1983, Ecological Entomology (8) 69-85
1Temporal patterns of seed use were studied from late winter to autumn in three species of seed-harvesting ants in the Sonoran Desert. Measures of effective foraging activity, dietary niche breadth and dietary niche overlaps were obtained each month and were tested for correlation with estimates of the...
Hydrogeologic and water-quality characteristics of the Prairie du Chien-Jordan aquifer, Southeast Minnesota
J. F. Ruhl, R. J. Wolf, D. G. Adolphson
1983, Water-Resources Investigations Report 83-4045
Quality of water in the Prairie du Chien-Jordan aquifer is generally good, except for some localized contamination, Coal-tar derivatives that contaminate the aquifer in St. Louis Park, a western suburb in the Twin Cities Metropolitan Area, pose the most serious threat to water quality. High hardness and iron concentration limit...
An updated Bouguer anomaly map of south-central West Africa
David A. Hastings
1983, Geophysics (48) 1120-1128
A new Bouguer gravity anomaly map compiled for western Africa adds data for Ghana, Guinea, and Liberia.The new data add detail to a key part of the Eburnean shield and assist in the development of a model of rifting at the time of the Eburnean orogeny, 2000 million years ago....
Salmonella enteritidis isolated from an eared grebe (Podiceps nigricollis)
Ruth M. Duncan, Richard K. Stroud, Louis N. Locke
1983, Journal of Wildlife Diseases (19) 63-64
The reported prevalence of salmonellosis in wild birds is relatively low, though the number of species of birds reported as having the disease or being carriers of the organism is increasing (Faddoul et al., 1966, Avian Dis. 10: 89- 94). The course of the disease in birds ranges from acute...
Serological comparison of selected isolates of Aeromonas salmonicida ssp. Salmonicida
G.B. Hahnel, R. W. Gould, E.S. Boatman
1983, Journal of Fish Diseases (6) 1-11
Eight isolates of Acronionus salmonicida ssp. salmonicida were collected during furunculosis epizootics in North American Pacific coast states and provinces. Both virulent and avirulent forms of each isolate, confirmed by challenge and electron microscopy, were examined. Serological comparisons by cross-absorption agglutination tests revealed no serological differences between isolates. Using...
Factors affecting dietary requirement and deficiency signs of L-tryptophan in rainbow trout
H. A. Poston, G. L. Rumsey
1983, Journal of Nutrition (113) 2568-2577
Two experiments were conducted to determine the concentration of dietary tryptophan needed for optimal growth and survival of fingerling rainbow trout (Salmo gairdneri), to characterize signs of tryptophan deficiency, and to ascertain the effects of niacin on deficiency signs. Test diets containing either hydrolyzed or intact casein were fed with...
