Loma sp. salmonids from the Eastern United States: Associated lesions rainbow trout
P.T. Markey, V. S. Blazer, M. S. Ewing, K. M. Kocan
1994, Journal of Aquatic Animal Health (6) 318-328
A microsporidian of the genus Loma was noted in the gills of rainbow trout Oncorhynchus mykiss from a state hatchery (Buford Trout Hatchery) in Georgia. Mortalities of varying severity occur at this hatchery every fall, and the microsporidian was noted during an experiment from August 1991 to January...

1994, Miscellaneous Field Studies Map 2275
This report revises Miscellaneous Field Studies Map MF-1188 (Rice and Smith, 1980).

Also included in the report is the proper...
Late winter survival of female mallards in Arkansas
Bruce D. Dugger, Kenneth J. Reinecke, Leigh H. Fredrickson
1994, Journal of Wildlife Management (58) 94-99
Determining factors that limit winter survival of waterfowl is necessary to develop effective management plans. We radiomarked immature and adult female mallards (Anas platyrhynchos) after the 1988 and 1989 hunting seasons in eastcentral Arkansas to test whether natural mortality sources and habitat conditions during late winter limit seasonal survival. We...
Maps summarizing geohydrologic information in an area of salt-water disposal, eastern Altamont-Bluebell petroleum field, Uinta Basin, Utah
Geoffrey W. Freethey
1994, Water-Resources Investigations Report 92-4043
In the Altamont-Bluebell Petroleum Field within the Uinta Basin of Utah, saline oil-production water is being injected into the Duchesne River Formation. On the basis of geohydrologic information, a qualitative assessment of the possible effects of this injection indicates that fresh groundwater in certain areas of the Duchesne River formation...
Polar bear maternity denning in the Beaufort Sea
Steven C. Amstrup, Craig L. Gardner
1994, Journal of Wildlife Management (58) 1-10
The distribution of polar bears (Ursus maritimus) is circumpolar in the Northern Hemisphere, but known locations of maternal dens are concentrated in relatively few, widely scattered locations. Denning is either uncommon or unknown within gaps. To understand effects of industrial development and propose increases in hunting, the temporal and spatial...

This guidebook for a 1-day drive in the Front Range west of Denver, Colorado, includes commentary on mountain landscapes, notes on the colorful mining history of the area, and discussions on the geology and some miningrelated environmental hazards in the Idaho Springs area. It was originally prepared as U.S. Geological...
Sea otter foraging behavior and hydrocarbon levels in prey
Angela M. Doroff, James L. Bodkin
Thomas R. Loughlin, editor(s)
1994, Book chapter, Marine mammals and the <i>Exxon Valdez</i>
Following the Exxon Valdez oil spill (EVOS), Prudhoe Bay crude oil from the vessel spread on the sea surface and covered coastal shores from western Prince William Sound (PWS) to the Alaska Peninsula. In PWS alone. acute mortality of sca otters at the time of the spill was estimated to...
Continent-ocean transition in Alaska: The tectonic assembly of eastern Denalia
Thomas E. Moore, Arthur Grantz, S. M. Roeske
1994, Book chapter, Phanerozoic evolution of North American continent ocean transitions
Alaska is the eastern, subaerial part of a large subcontinent of distinctive tectonic character that serves as an isthmus between nuclear North America, with its fringing belt of allochthonous terranes, and the accreted terranes and volcanic belts that constitute northeastern Russia. Physiographically, this subcontinent, which we name Denalia, is a...
Effects of surficial geology, lakes and swamps, and annual water availability on low flows of streams in central New England, and their use in low-flow estimation
S. William Wandle Jr., Allan D. Randall
1994, Water-Resources Investigations Report 93-4092
Equations developed by multiple-regression analysis of data from 49 drainage basins in Massachusetts, New Hampshire, Rhode Island, Vermont, and southwestern Maine indicate that low flow of streams in this region is largely a function of the amount of water available to the basin and the extent of surficial sand and...
Simulation of rainfall-runoff for basins in the Rolla, Missouri, area
Robert R. Holmes Jr., J. W. East
1994, Water-Resources Investigations Report 94-4019
Important rainfall-runoff characteristics for basins in the Rolla, Missouri, area were determined to be overland flow, interception storage, interception losses, evaporation, and infiltration. Using these characteristics, the U.S. Environmental Protection Agency's Stormwater Management Model (SWMM) was configured for basins in the study area. The data network for the model calibration...
Sources and transport of sediment, nutrients, and oxygen-demanding substances in the Minnesota River basin, 1989-92
G. A. Payne
1994, Water-Resources Investigations Report 93-4232
The Minnesota River, 10 major tributaries, and 21 springs were sampled to determine the sources and transport of sediment, nutrients, and oxygen- demanding substances. The study was part of a four-year assessment of non-point source pollution in the Minnesota River Basin. Runoff from tributary watersheds was identified as the primary...
