Winter biomass and nutrient values of three seagrass species as potential foods for redheads (Aythya americana eyton) in Chandeleur Sound, Louisiana
Thomas C. Michot, Paul C. Chadwick
1994, Wetlands (14) 276-283
We studied biomass and macronutrient content ofHalodule wrightii (shoalgrass) throughout the winter and ofThalassia testudinum (turtlegrass) andSyringodium filiforme (manateegrass) in January in Chandeleur Sound, LouisianaHalodule, the primary fcod of wintering redheads, had the lowest biomass of the three species on the study area in mid-winter....
Strontium isotope geochemistry of soil and playa deposits near Yucca Mountain, Nevada
Brian D. Marshall, Shannon A. Mahan
1994, Conference Paper, High level radioactive waste management: Proceedings of the fifth annual international conference
The isotopic composition of strontium contained in the carbonate fractions of soils provides an excellent tracer which can be used to test models for their origin. This paper reports data on surface coatings and cements, eolian sediments, playas and alluvial fan soils which help to constrain a model for formation...

American White Pelicans at the Molly Islands, in Yellowstone National Park: Twenty-two years of boom-and-bust breeding, 1966-87
Kenneth L. Diem, Bruce H. Pugesek
1994, Colonial Waterbirds (17) 130-145
Systematic monitoring of nesting and fledging of American White Pelicans (Pelecanus erythrorhynchos) breeding on the Molly Islands In Yellowstone Lake was carried on for 20 years between 1966 and 1987. The mean number of pelicans fledged during those years was 214 (±196 SD). In five of those years the number...
Structure and bulk composition of the Tin Mountain pegmatite, Black Hills, South Dakota
J.J. Norton
1994, Economic Geology (89) 1167-1175
Construction of structure contour and isopach maps has yielded a rather simple and orderly interpretation of the structure and has led to calculations of the tonnage of each of the internal units and of the bulk composition of the pegmatite. The outcropping part of the pegmatite trends S 75° E...
Geology and occurrence of radon
R. Randall Schumann, Linda C. Gundersen, A. B. Tanner
1994, Book chapter, Radon: Prevalence, measurements, health risks and control
The accumulation of radon indoors is commonly due to movement of radon from adjacent soil and rock into a building foundation through joints, utility openings, cracks, or porous block walls. When air pressure inside the building is lower than that in the soil, pressure-driven flow of radonbearing soil gas can...
Body size and condition, age, plumage quality, and foods of prenesting male cinnamon teal in relation to pair status
William L. Hohman, C. Davison Ankney
1994, Canadian Journal of Zoology (72) 2172-2176
Male-biased sex ratios in waterfowl may contribute to sexual selection and permit females to be the deciding sex in mate selection. Male characteristics potentially influencing female choice include male age, size, plumage quality, and body condition (i.e., relative body mass, fat content, or protein content). By examining characteristics of prenesting...

1994, Water International (19) 177-185
The Scientific Assessment and Strategy Team was formed to provide scientific advice and assistance to federal officials responsible for making decisions with respect to flood recovery in the Upper Mississippi River Basin (above Cairo, Illinois) as a result of the 1993 flooding. The team assembled data from a wide variety...

Nest monitoring using a micro-video camera
Keith Ouchley, Robert B. Hamilton, Scott A. Wilson
1994, Journal of Field Ornithology (65) 410-412
A system is described that utilizes a battery operated micro-video camera mounted on an extendible pole for monitoring high nests. The video image is transmitted to a hand-held monitor at ground level and provides accurate information about the contents of high nests. ...
Biostratigraphic constraints on formation and timing of accretion in a subduction complex: An example from the Franciscan Complex of Northern California
Y. Isozaki, M. Clark Blake Jr.
1994, Journal of Geology (102) 283-296
The determination of the total age coverage of pelagic bedded chert is particularly important in studies of ancient accretionary complexes because the time span represents the minimum travel time of an oceanic plate before accretion at an island arc or continental margin. The Yolla Bolly terrane of the Franciscan Complex...
