Lake acidity and mercury content of fish in Darwin National Reserve, Russia
Terry A. Haines, V. Komov, C. H. Jagoe
1992, Environmental Pollution (78) 107-112
Darwin National Reserve is a protected natural area on the north-west shore of the Rybinsk Reservoir, 350 km north of Moscow. In June 1989, six lakes in the Reserve and the reservoir were surveyed to assess lake acidity and the mercury content of perch, Perca fluviatilis. Five were seepage lakes...
Change-in-ratio methods for estimating population size
Mark S. Udevitz, Kenneth H. Pollock
Dale R. McCullough, Reginald H. Barrett, editor(s)
1992, Book chapter, Wildlife 2001: Populations
Change-in-ratio (CIR) methods can provide an effective, low cost approach for estimating the size of wildlife populations. They rely on being able to observe changes in proportions of population subclasses that result from the removal of a known number of individuals from the population. These methods were first introduced in...
The Parkfield earthquake prediction of October 1992; the emergency services response
R. Andrews
1992, Earthquakes & Volcanoes (USGS) (23) 170-174
The science of earthquake prediction is interesting and worthy of support. In many respects the ultimate payoff of earthquake prediction or earthquake forecasting is how the information can be used to enhance public safety and public preparedness. This is a particularly important issue here in California where we have such...
The National Landslide Information Center; data to reduce landslide damage
W. M. Brown III
1992, Earthquakes & Volcanoes (USGS) (23) 52-57
Almost every day a landslide disasters occurs somewhere in the world. Nearly any time there is heavy rainfall, an earthquake, a volcanic eruption, strong wave action on a shoreline, or some ill-considered alteration of sloping land by humans, landslides occur. In a world of persistent and increasing construction on and occupation...
Preliminary damage and intensity survey
L. R. Brewer
1992, Earthquakes & Volcanoes (USGS) (23) 219-226
A major earthquake struck the Mojave Desert region in southern California at about 5 a.m. local time on June 28th, 1992. Seismologists located the epicenter of the magnitude 7.6 (Ms) earthquake 5-10km southwest of Landers, a small community about 150km east of Los Angeles. the earthquake shook a wide area...
Suppression of guinea pig ileum induced contractility by plasma albumin of hibernators
David S. Bruce, Douglas L. Ambler, Timothy M. Henschel, Peter R. Oeltgen, Sita P. Nilekani, Steven C. Amstrup
1992, Pharmacology Biochemistry and Behavior (43) 199-203
Previous studies suggest that hibernation may be regulated by internal opioids and that the putative “hibernation induction trigger” (HIT) may itself be an opioid. This study examined the effect of plasma albumin (known to bind HIT) on induced contractility of the guinea pig ileum muscle strip. Morphine (400 nM) depressed...
Breeding population inventories and measures of recruitment
L.M. Cowardin, R.J. Blohm
D.J. Batt, A. D. Afton, M.G. Anderson, C.D. Ankney, Douglas H. Johnson, J.A. Kadlec, Gary L. Krapu, editor(s)
1992, Book chapter, Ecology and Management of Breeding Waterfowl
In this chapter we review the techniques used to measure two important parameters of waterfowl populations, size of breeding population and recruitment. If waterfowl are to be managed toward goals defined in terms of population sizes such as those in the recently signed North American Waterfowl Management Plan (U.S. Fish...
Sediment bioaccumulation testing with fish
Michael J. Mac, Christopher J. Schmitt
G. Allen Burton Jr., editor(s)
1992, Book chapter, Sediment toxicity assessment
In this chapter, we discuss methods for conducting bioaccumulation bioassays with fish; the advantages and disadvantages of using fish rather than invertebrates; and problems associated with bioaccumulation testing, with a special emphasis on statistical treatment....
Sampling vadose-zone water for a volatile organic compound at Picatinny Arsenal, New Jersey
James A. Smith, H. Jean Cho, Peter R. Jaffe, Cecilia L. MacLeod, Susan A. Koehnlein
1992, Journal of Environmental Quality (21) 264-271
A new method of collecting samples of unsaturated-zone water for quantitative analysis for a volatile organic compound, trichloroethene (TCE), was compared to three other, previously described sampling methodologies in the laboratory and in the field. In the laboratory, prepared water samples containing TCE in a known concentration (20 µg/L) were...
Sedimentary history of the Tethyan margins of eastern Gondwana during the Mesozoic
James G. Ogg, Felix Gradstein, Julie A. Dumoulin, Massimo Sarti, Paul Brown
1992, Book chapter, Geophysical Monograph Series, Volume 70: Synthesis of results from scientific drilling in the Indian Ocean
A composite Mesozoic geological history for the Gondwana margins to the Eastern Tethys Ocean can be assembled from stratigraphic successions on the Australian and Himalayan margins and from drill sites of Ocean Drilling Program Legs 122 and 123. During the Triassic, this region drifted northwards, entering tropical paleolatitudes during the...
Lake trout spawning habitat in the Six Fathom Bank-Yankee Reef lake trout sanctuary, Lake Huron
Thomas A. Edsall, Charles L. Brown, Gregory W. Kennedy, Thomas P. Poe
1992, Journal of Great Lakes Research (18) 70-90
Attempts to reestablish self-sustaining stocks of lake trout (Salvelinus namaycush) in the lower four Great Lakes, where the species was extinguished in the 1950s and 1960s, have been largely unsuccessful. To avoid many of the problems believed to be contributing to this failure, the fishery management community recently established several...
Bioaccumulation of hydrocarbons derived from terrestrial and anthropogenic sources in the Asian clam, Potamocorbula amurensis, in San Francisco Bay estuary
Wilfred E. Pereira, Frances D. Hostettler, John B. Rapp
1992, Marine Pollution Bulletin (24) 103-109
An assessment was made in Suisun Bay, California, of the distributions of hydrocarbons in estuarine bed and suspended sediments and in the recently introduced asian clam, Potamocorbula amurensis. Sediments and clams were contaminated with hydrocarbons derived from petrogenic and pyrogenic sources. Distributions of alkanes and of hopane and sterane biomarkers in...
The Pearlette family ash beds in the Great Plains: Finding their identities and their roots in the Yellowstone country
R.E. Wilcox, C. W. Naeser
1992, Quaternary International (13-14) 9-13
For many years the numerous deposits of so-called 'Pearlette volcanic ash' in the Great Plains region of the United States were considered to be the remnants of the same volcanic event, and were used as a time-stratigraphic marker of probable Middle Pleistocene age. Although a few early workers had suggested...
Mineralogy and geochemistry of two metamorphosed sedimentary manganese deposits, Sierra Nevada, California, USA
M.J.K. Flohr, J.S. Huebner
1992, LITHOS (29) 57-85
Laminated to massive rhodochrosite, hausmannite, and Mn-silicates from the Smith prospect and Manga-Chrome mine, Sierra Nevada, California were deposited as ocean floor sediments associated with chert and shale. The principal lithologies at Smith are chert, argillite, rhodochrosite-, hausmannite- and chlorite-rich layers, and relatively uncommon layers of jacobsite. The Manga-Chrome mine...
