The Mount Mazama climactic eruption (6900 BP) and resulting convulsive sedimentation on the continent, ocean basin, and Crater Lake caldera floor
C. Hans Nelson, Paul R. Carlson, Charles R. Bacon
1988, Book chapter, Sedimentologic consequences of convulsive geologic events
The climactic eruption of Mount Mazama and the resulting sedimentation may have been the most significant convulsive sedimentary event in North America during Holocene time. A collapse caldera 1,200 m deep and 10 km in diameter was formed in Mount Mazama, and its floor was covered by hundreds of meters...
Mg/Mn partitioning as a test for equilibrium between coexisting Fe-Ti oxides
Charles R. Bacon, M.M. Hirschmann
1988, American Mineralogist (73) 57-61
Partitioning of Mg and Mn between titanomagnetite and ferrian ilmenite of volcanic rocks provides a test for equilibrium between coexisting phases. A plot of log(Mg/Mn)-, vs. log(Mg/Mn),, for 213 homogeneous oxide pairs from volcanic rocks yields a straight line over more than two orders of magnitude variation in Mg/Mn. Analyses...
Western state instream flow programs: a comparative assessment
Matthew J. McKinney, Jonathan G. Taylor
1988, Report, Instream Flow Information Paper
During their early history, Western States water rights laws were primarily means for facilitating and regulating water diversions for offstream, consumptive use. More recently, a countervailing concern for instream values such as fish and wildlife habitat, recreation, aesthetic values, and water quality has emerged in the legislative and administrative handling...
Historical changes in the major fish resources of the Great Lakes
Wilbur L. Hartman
Marlene S. Evans, editor(s)
1988, Book chapter, Toxic contaminants and ecosystem health: a Great Lakes focus
My purpose here is to review historic changes in the major fish resources of the five Great Lakes, and to identify the cause or causes for those changes. In some instances it will be clear that intensive fishing was the primary cause of change; in other instances it will be...
Results of a survey of U.S. Fish and Wildlife Service Endangered Species and Ecological Services Field Offices, Refuges, Hatcheries, and Research Centers
Douglas N. Gladwin, Duane A. Asherin, Karen M. Manci
1988, Report, Effects of aircraft noise and sonic booms on fish and wildlife
The National Ecology Research Center (Center), as part of an ongoing research study on the effects of low altitude aircraft operations on fish and wildlife, conducted a survey in January 1987 of all U.S. Fish and Wildlife Service (Service) regional directors, research center directors, Ecological Services and Endangered Species field...
Thematic mapping from satellite imagery
J. Denegre, editor(s)
1988, Book
This report, produced between 1984 and 1987 in a bilingual edition (English and French), provides a wealth of information on a wide variety of cartographic applications which are being developed to make effective use of new data that is now being collected by Earth observation satellites. At a time when...
Responses of aquatic and streamside amphibians to timber harvest: a review
R. Bruce Bury, Paul Stephen Corn
1988, Book chapter, Streamside management: riparian wildlife and forestry interactions
Stream-dwelling amphibians, which can be the dominant vertebrates of small streams in forests of the Pacific Northwest, are prototypic riparian or­ ganisms. Larvae of several species are totally aquatic, while adults use the terrestrial streamside (riparian) habitat to varying degrees. Impacts of timber harvest vary among species, physical habitats, and...
River basins of the United States: the Potomac
Water Resources Division, U.S. Geological Survey
1988, Report
This leaflet, one of a series on the river basins of the United States, contains information on the Potomac River Basin, including a brief early history, a description of the physical characteristics, and other statistical data. At present, other river basins included in the series are The Colorado, The Columbia,...
Coastal erosion and accretion

The past, present, and future of manatees in the southeastern United States: realities, misunderstandings and enigmas
T. J. O'Shea
1988, Book, Proceedings of the Third Southeastern Nongame and Endangered Wildlife Symposium
A review of the historical and recent (1970s-1980s) literature on the distribution, abundance, and mortality of West Indian manatees (Trichechus manatus) in the southern United States is presented. Recent unpublished data on mortality, Florida boat registrations, size of certain manatee wintering populations, and records outside of Florida are also given....
Douglas-fir forests in the Cascade Mountains of Oregon and Washington: is the abundance of small mammals related to stand age and moisture?
P.S. Coen, R.B. Bury, T.A. Spies
1988, Report, Management of amphibians, reptiles, and small mammals in North America
Red tree voles (Arborimus longicaudus) were the only small mammal strongly associated with old-growth forests, whereas vagrant shrews (Sorex vagrans) were most abundant in young forests. Pacific marsh shrews (S. bendirii) were most abundant in wet old-growth forests, but abundance of this species in young (wet) forests needs further study....
Isolation and identification of trichothecenes from Fusarium compactum suspected in the aetiology of a major intoxication of sandhill cranes
Richard J. Cole, Joe W. Dorner, John Gilbert, David N. Mortimer, Colin Crews, J.C. Mitchell, Ronald M. Windingstad, Paul E. Nelson, Horace G. Cutler
1988, Journal of Agricultural and Food Chemistry (36) 1163-1167
Isoneosolaniol (4,8-diacetoxy-12,13-epoxytrichothec-9-ene-3,15-diol) and other unidentified trichothecene mycotoxins were isolated from culture extracts of two highly toxigenic strains of Fusarium compactum cultured from waste peanuts involved in an acute intoxication of sandhill cranes (Grus canadensis). Neosolaniol and other unidentified trichothecenes were detected in waste peanuts collected from affected areas. The structure...
Cattle grazing and small mammals on the Sheldon National Wildlife Refuge, Nevada
John L. Oldemeyer, L. R. Allen-Johnson
1988, Report, Management of amphibians, reptiles, and small mammals in North America: Proceedings of the symposium
We studied effects of cattle grazing on small mammal microhabitat and abundance in northwestern Nevada. Abundance, diversity, and microhabitat were compared between a 375-ha cattle exclosure and a deferred-rotation grazing allotment which had a three-year history of light to moderate use. No consistent differences were found in abundance, diversity, or...
