The effects of ingested petroleum on the maphthalene-metabolizing properties of the liver tissue in seawater-adapted mallard ducks (Anas platyrhynchos)
J. Gorsline, W. N. Holmes, J. Cronshaw
1981, Environmental Research (24) 377-390
Hepatic mixed function oxidase activities were estimated in seawater-adapted mallard ducks (Anas platyrhynchos) that had been consuming food contaminated with one of five different types of crude oil. After 50 days of exposure to contaminated food, enzyme activities of liver microsomal preparations were assessed in terms of their naphthalenemetabolizing properties...
Iatrogenic salt poisoning in captive sandhill cranes
J. C. Franson, L. Sileo, W. James Fleming
1981, Journal of the American Veterinary Medical Association (179) 1211-1213
Salt poisoning developed in captive sandhill cranes (Grus canadensis) when sea salt was added to normal drinking water to produce a sodium chloride concentration of 1%. Two of 18 cranes died and 2 were euthanatized when moribund. Muscle weakness, paresis, dyspnea, and depression were observed. Brain and serum sodium, serum...

The field notes of J. R. Slevin written during the expedition of the California Academy of Sciences to the Galapagos Islands in 1905-1096 contain previously unavailable data on the marine turtles of the eastern Pacific. 'Land basking' by green turtles in Galapagos was predominately, if not exclusively, a female behavior....

Geologic evidence for age of deposits at Hueyatlaco archeological site, Vasequillo, Mexico
V. Steen-McIntyre, R. Fryxell, H.E. Malde
1981, Quaternary Research (16) 1-17
Direct tracing of beds during excavation in May 1973, confirmed that the artifact-bearing layers at Hueyatlaco underlie 10 m of fine-grained, water-laid deposits that constitute part of the wide-spread Valsequillo gravels. Dissection of these deposits by the adjacent Río Atoyac has reached a depth of 50 m. The stratigraphic section...
Rock-weathering rates as functions of time
Steven M. Colman
1981, Quaternary Research (15) 250-264
The scarcity of documented numerical relations between rock weathering and time has led to a common assumption that rates of weathering are linear. This assumption has been strengthened by studies that have calculated long-term average rates. However, little theoretical or empirical evidence exists to support linear rates for most chemical-weathering...
The terminal Eocene event and the Polish connection

1981, Palaeogeography, Palaeoclimatology, Palaeoecology (36) 321-362
The Eocene/Oligocene boundary in Europe is marked by major discontinuities in all environments: the “Grande Coupure” in continental mammals; the elimination of semitropical elements from high-latitude floras; the virtually complete replacement of the shallow-marine malacofauna; and an extraordinary downslope excursion of carbonate deposition in deep-ocean basins (drop in the CCD)....
Lower Eocene alluvial paleosols (Willwood Formation, Northwest Wyoming, U.S.A.) and their significance for paleoecology, paleoclimatology, and basin analysis
T. M. Bown, M. J. Kraus
1981, Palaeogeography, Palaeoclimatology, Palaeoecology (34) 1-30
The lower Eocene Willwood Formation of northwest Wyoming is a 700 m thick accumulation of alluvial floodplain and channel mudstones and sandstones, nearly all of which show paleopedogenic modifications. Pedogenesis of Willwood sandstones is indicated by taproot and vertebrate and invertebrate bioturbation, early local cementation by calcium carbonate, and thin...
Late Cenozoic marine deposition in the United States Atlantic Coastal Plain related to tectonism and global climate
B. W. Blackwelder
1981, Palaeogeography, Palaeoclimatology, Palaeoecology (34) 87-114
Major hiatuses in upper Cenozoic marine deposits in the United States Atlantic Coastal Plain are recognized on the basis of molluscan faunal changes at erosional unconformities. These hiatuses generally coincided with periods of global cooling and ice sheet formation. Such hiatuses provide information to supplement global climatic data. Major hiatuses...
Natural occurrence and significance of fluids indicating high pressure and temperature
E. Roedder
1981, Physics and Chemistry of the Earth (13-14) 9-39
Most natural minerals have formed from a fluid phase such as a silicate melt or a saline aqueous solution. Fluid inclusions are tiny volumes of such fluids that were trapped within the growing crystals. These inclusions can provide valuable but sometimes ambiguous data on the temperature, pressure, and composition of...
Physical-chemical conditions of ore deposition
P. B. Barton Jr.
1981, Physics and Chemistry of the Earth (13-14) 509-528
Ore deposits form under a wide range of physical and chemical conditions, but those precipitating from hot, aqueous fluids—i.e. the hydrothermal deposits—form generally below 700°C and at pressures of only 1 or 2 kbar or less. Natural aqueous fluids in rocks may extract metal and sulfur from a variety of...

Colleen M. Handel, Margaret R. Petersen, Robert E. Gill Jr., Calvin J. Lensink
1981, FWS/OBS 81/12
The demand for information on birds in Alaska has surged within the past few years, primarily because of the need to adequately assess the impacts of a wide range of planned developments. The accompanying increase in studies of avian populations has resulted in a growing need for a comprehensive bibliography...

Charles K. Paull, William P. Dillon
1981, Miscellaneous Field Studies Map 1252
A strong reflection parallel to the sea floor has been observed in seismic-reflection profiles in the Blake Ridge area off the southeastern United States. This reflection occurs at a subbottom depth of 400 to 700 m, in water depths of 750 to 3750 m. Because the reflection parallels the sea...
