Geomorphic domains and linear features on Landsat images, Circle quadrangle, Alaska
S. L. Simpson
1984, Open-File Report 83-170-E
A remote sensing study using Landsat images was undertaken as part of the Alaska Mineral Resource Assessment Program (AMRAP). Geomorphic domains A and B, identified on enhanced Landsat images, divide Circle quadrangle south of Tintina fault zone into two regional areas having major differences in surface characteristics. Domain A is...
First evidence of successful natural reproduction by planted lake trout in Lake Huron
Robert T. Nester, Thomas P. Poe
1984, North American Journal of Fisheries Management (4) 126-128
Twenty-two lake trout (Salvelinus namaycush) swim-up fry, 24-27 mm long, were captured with emergent fry traps and a tow net in northwestern Lake Huron on a small nearshore reef off Alpena, Michigan, between May 10 and June 1, 1982. These catches represent the first evidence of successful production of swim-up...
Origin of epigenetic calcite in coal from Antarctica and Ohio based on isotope compositions of oxygen, carbon and strontium
G. Faure, G. Botoman
1984, Chemical Geology (46) 313-324
Isotopic compositions of oxygen, carbon and strontium of calcite cleats in coal seams of southern Victoria Land, Antarctica, and Tuscarawas County, Ohio, contain a record of the conditions a the time of their formation. The Antarctic calcites (?? 18O(SMOW) = +9.14 to +11.82%0) were deposited from waters enriched in 16O...

Holocene eruptive activity of El Chichón Volcano, Chiapas, Mexico
Robert I. Tilling, Meyer Rubin, Haraldur Sigurdsson, Steven Carey, Wendell A. Duffield, William I. Rose Jr.
1984, Science (224) 747-749
Geologic and radiometric-age data indicate that El Chichón was frequently and violently active during the Holocene, including eruptive episodes about 600, 1250, and 1700 years ago and several undated, older eruptions. These episodes, involving explosive eruptions of sulfur-rich magma and associated dome-growth processes, were apparently separated by intervals of approximately...
Seed predation due to the yucca moth symbiosis
Jon E. Keeley, Sterling C. Keeley, C. C. Swift, J. Lee
1984, American Midland Naturalist (112) 187-191
All species of Yucca (Agavaceae) require the pollinator services of a species of moth in the genus Tegeticula (Lepidoptera: Incurvariidae). These moths oviposit in the ovary of the plants and the larvae are entirely dependent upon Yucca seeds for food. The extent and distribution of larval seed predation was examined...
Modeling behavior of prescribed fires in Yosemite National Park
J. W. van Wagtendonk, S.J. Botti
1984, Journal of Forestry (82) 479-484
The National Fire Danger Rating System and the Fire Behavior Prediction System were tested on prescribed fires burning underneath canopies in six fuel types in Yosemite National Park, California. The mean error for rate of spread was +0.03 foot per minute for the NFDRS and -0.15 foot for the...
Age-related mortality in a wintering population of dunlin
B.E. Kus, P. Ashman, G. Page, L. Stenzel
1984, The Auk (101) 69-73
Despite considerable evidence that juvenile shorebirds experience significantly higher annual mortality rates than adults, identification and quantification of the sources of mortality have received little attention. We found that the proportion of juvenile Dunlins (Calidris alpina) in the kills of a Merlin (Falco columbarius) one winter at Bolinas Lagoon, California...
Effects of dietary excesses of branched-chain amino acids on the metabolism and tissue composition of lake trout (Salvelinus namaycush)
S. G. Hughes, G. L. Rumsey, M.C. Nesheim
1984, Comparative Biochemistry and Physiology, Part A: Physiology (78A) 413-418
1. Excesses of either leucine, isoleucine or valine were fed in separate experiments to determine if the branched-chain amino acid antagonism reported in other animals occur in trout (Salvelinus namaycush).2. Parameters measured include growth rate, feed utilization efficiency, plasma and muscle-free amino acids, carcass composition and branched-chain amino acid aminotransferase.3....

Radon in earth-sheltered structures
E. R. Landa
1984, Underground Space (8) 264-269
Radon concentration in the indoor air of six residential and three non-residential earth-sheltered buildings in eastern Colorado was monitored quarterly over a nine-month period using passive, integrating detectors. Average radon concentrations during the three-month sampling periods ranged from about 1 to 9 pCi/L, although one building, a poorly ventilated storage...

Swainson's hawk nesting ecology in North Dakota

Swainson's Hawks (Buteo swainsoni) were studied at 270 occupied nest sites in south-central North Dakota on a 1,259-km2 intensive study block and on a surrounding study area (16,519 km2) during three breeding seasons. On the intensive study block the number of occupied nests ranged from 46 in 1977 to 100...
