The comparison of usage and availability measurements for evaluating resource preference
Douglas H. Johnson
1980, Ecology (61) 65-71
Modern ecological research often involves the comparison of the usage of habitat types or food items to the availability of those resources to the animal. Widely used methods of determining preference from measurements of usage and availability depend critically on the array of components that the researcher, often with a...
Plant stress detection by remote measurement of fluorescence
J. C. McFarlane, Robert D. Watson, Arnold F. Theisen, R. D. Jackson, W. L. Ehrler, P. J. Pinter Jr., S. B. Idso, R. J. Reginato

Geoscientists for international development
David A. Hastings
1980, The British Geologist (6) 104-106
Professional societies are usually concerned with the advancement of scientific knowledge, but a relative newcomer to the international scene has a different focus - geoscience development in the Third World. David Hastings, a member of AGID, explains....
Atlantic Flyway review: Region V: Laurel, Prince Georges County, MD (390-0765)
Chandler S. Robbins
1980, North American Bird Bander (5) 34-34
Despite a 22% increase in net-hours, the number of new birds banded dropped 26% from 1977. The decrease was noted in each month and was spread among all of the commonest species, including summer residents, winter residents, permanent residents, and transients. The greatest declines were in Scarlet Tanager (84%), Blue...

Geohydrology of southwestern Kansas
Edwin D. Gutentag, David H. Lobmeyer, Steven E. Slagle
1980, Open-File Report 80-218
Southwestern Kansas is one of the principal areas of ground-water development for irrigation in the State, and many reports are available concerning ground-water conditions in the area. The purposes of this investigation were to consolidate and update data, to determine the extent and effects of irrigation development on the ground-water...
Earthquake alarm; operating the seismograph station at the University of California, Berkeley.
B. Stump
1980, Earthquake Information Bulletin (USGS) (12) 88-97
An alarm bell rings at the seismographic station and at the office of the campus police. It is 3:00 on a foggy San Francisco morning. Somewhere in the world an earthquake has occurred. The police telephone the duty seismologist at home telling him that the alarm has triggered. He makes...

An economical educational seismic system
J. D. Lehman
1980, Earthquake Information Bulletin (USGS) (12) 197-199
There is a considerable interest in seismology from the nonprofessional or amateur standpoint. The operation of a seismic system can be satisfying and educational, especially when you have built and operated the system yourself. A long-period indoor-type sensor and recording system that works extremely well has been developed in the...

Applications of statistics to thematic mapping.
G.H. Rosenfield, M.L. Melley
1980, Photogrammetric Engineering and Remote Sensing (46) 1287-1294
Two statistical problems occurring in the effort to analyze thematic maps and mapping are determining the accuracy of thematic content and comparing factors studied in thematic mapping. Statistical procedures applicable to thematic mapping involve sampling, determining accuracy, and comparing factors. A sampling procedure using an unaligned pattern within a square...
Bordetella bronchiseptica associated with pulmonary disease in mountain voles (Microtus montanus)
Wayne I. Jensen, Ruth M. Duncan
1980, Journal of Wildlife Diseases (16) 11-14
Bordetella bronchiseptica was isolated from the lungs of all of six mountain voles (Microtus montanus) found dead or dying of pulmonary infection near the Bear River Research Station in northern Utah in January, 1973. The possibility of concomitant viral or mycoplasmal infection was not ruled out....
Compositional controls on spinel clouding and garnet formation in plagioclase of olivine metagabbros, Adirondack Mountains, New York
J. M. McLelland, P.R. Whitney
1980, Contributions to Mineralogy and Petrology (73) 243-251
Olivine metagabbros from the Adirondacks usually contain both clear and spinel-clouded plagioclase, as well as garnet. The latter occurs primarily as the outer rim of coronas surrounding olivine and pyroxene, and less commonly as lamellae or isolated grains within plagioclase. The formation of garnet and metamorphic spinel is dependent upon...
Petrology of Hualalai volcano, Hawaii: Implication for mantle composition
D.A. Clague, E.D. Jackson, T. L. Wright
1980, Bulletin Volcanologique (43) 641-656
Hualalai is one of five volcanoes whose eruptions built the island of Hawaii. The historic 1800-1801 flows and the analyzed prehistoric flows exposed at the surface are alkalic basalts except for a trachyte cone and flow at Puu Waawaa and a trachyte maar deposit near Waha Pele. The 1800-1801 eruption...
Opaque minerals as aids in distinguishing between source and sorting effects on beach sand mineralogy in southwestern Oregon
G. Luepke
1980, Journal of Sedimentary Petrology (50) 489-496
Both source area and wave sorting affect the heavy-mineral distributions of beach sands. Although source and sorting effects are difficult to distinguish, they can be separated on four Oregon beaches by studying the magnetic fraction of the sand. Prominent headlands bound the four...

Toxicity and efficacy of Furanace on channel catfish Ictalurus punctatus (Rafinesque) infected experimentally with Aeromonas hydrophila
A.J. Mitchell, J.A. Plumb
1980, Journal of Fish Diseases (3) 93-99
The 96-h medium tolerance limit of Furanace (nifurpirinol: P-7138) for channel catfish Ictalurus punctatus at 21°C was 0-94 mg/1. The most effective treatment level for channel catfish, experimentally infected with Aeromonas hydrophila, was 2mg/1 for 6.5 h. Furanace at 0.5 and 1.0 mg/1 in brain heart infusion agar reduced in vitro growth of A. hydrophila and at...
