A glossary for avian conservation biology
Rolf R. Koford, J.B. Dunning Jr., C. A. Ribic, D.M. Finch
1994, The Wilson Bulletin (106) 121-137
This glossary provides standard definitions for many of the terms used in avian conservation biology. We compiled these definitions to assist communication among researchers, managers, and others involved in the Neotropical Migratory Bird Conservation Program, also known as Partners in Flight. We used existing glossaries and recent literature to prepare...
1:2,000,000-scale Counties of the United States
K.J. Lanfear
1994, Report
This coverage is of the county boundaries of the conterminous United States. It was derived from the Digital Line Graph (DLG) files representing the 1:2,000,000-scale map in the National Atlas of the United States....
Simulation of ground-water flow and the movement of saline water in the Hueco Bolson aquifer, El Paso, Texas, and adjacent areas
George E. Groschen
1994, Open-File Report 92-171
The Hueco bolson aquifer is being pumped at increasing rates to supply water for El Paso, Texas, and Ciudad Juarez, Mexico. Water-use projections for 1984-2000 indicate that the upward trend in pumping rates probably will continue, which will put an increasing burden on the limited freshwater resources of the aquifer....
Locating, constructing, and managing islands for nesting waterfowl
John T. Lokemoen, Terry A. Messmer
1994, Report
The purpose of this extension bulletin is to assist public and private managers in locating, constructing, and managing islands to enhance nest success of waterfowl. The information is from studies by the Northern Prairie Wildlife Research Center, Jamestown, North Dakota, and information collected by biologists working at sites throughout the...
Ground water and the rural homeowner
Roger M. Waller
1994, Report
As the salesmen sang in the musical The Music Man, "You gotta know the territory." This saying is also true when planning to buy or build a house. Learn as much as possible about the land, the water supply, and the septic system of the house before buying or building....
Evapotranspiration estimation using a normalized difference vegetation index transformation of satellite data
P. M. Seevers, R. W. Ottmann
1994, Hydrological Sciences Journal (39) 333-345
Evapotranspiration of irrigated crops on two irrigation service areas along the lower Colorado River was estimated using a normalized difference vegetation index of satellite data. A procedure was developed which equated the index to crop coefficients. Evapotranspiration estimates for fields for three dates of thematic mapper data were highly correlated...
The status of sea ducks in the North Pacific Rim: Toward their conservation and management
R. Ian Goudie, Solange Brault, Bruce Conant, Alexander V. Kondratyev, Margaret R. Petersen, Kees Vermeer
Richard E. McCabe, Kelly G. Wadsworth, editor(s)
1994, Conference Paper, Transactions of the fifty-ninth North American wildlife and natural resources conference
Sea ducks (tribe Mergini after Johnsgard 1960) are the most northerly distributed ducks, and species diversity is greatest in the North Pacific. They exploit a diversity of inshore and offshore marine habitats during the non-breeding season, and their use of habitat during breeding varies from coastal through freshwater wetlands of...
Specific yield as determined by type-curve analysis of aquifer-test data
Allen F. Moench
1994, Ground Water (32) 949-957
The commonly used analytical solution developed by Neuman for a homogeneous, water-table aquifer assumes that the drainage of pores in the zone above the water table due to lowering of the water table occurs instantaneously. Noninstantaneous drainage of pores in the unsaturated zone accounts for the finding that both type-curve...
Graptemys ernsti
J.E. Lovich, C.J. McCoy
1994, Book chapter, Catalogue of American Amphibians and Reptiles
No abstract available at this time...
Magnitude and frequency of floods in Alaska and conterminous basins of Canada
Stanley H. Jones, Charles B. Fahl
1994, Water-Resources Investigations Report 93-4179
Equations for estimating the magnitude and frequency of floods at ungaged sites on streams in Alaska and conterminous basins of Canada were developed using multipleregression analyses of basin climatic and physical characteristics and peak-flow statistics from 260 gaged locations in Alaska and 72 gaged locations in Canada. Methods are presented...
An analysis of human-induced land transformations in the San Francisco Bay/Sacramento area
David A. Kirtland, L.J. Gaydos, Keith Clarke, Lee DeCola, William Acevedo, Cindy Bell
1994, World Resource Review (6) 206-217
Part of the U.S. Geological Survey's Global Change Research Program involvesstudying the area from the Pacific Ocean to the Sierra foothills to enhance understanding ofthe role that human activities play in global change. The study investigates the ways thathumans transform the land and the effects that changing the landscape may...
Assessing Crow Indian coal resources: GIS in action
W.D. Watson, K. Bryant, N.K. Gardner, M. S. Grim, G. Lebing
Roy Welch, Marguerite Remillard, editor(s)
1994, Conference Paper, Proceedings of the symposium on mapping and geographic information systems: Commission IV Symposium
No abstract available....
Genetic diversity in Arctic-nesting geese: Implications for management and conservation
Craig R. Ely, Kim T. Scribner
Richard E. McCabe, Kelly G. Wadsworth, editor(s)
1994, Conference Paper, Transactions of the fifty-ninth North American wildlife and natural resources conference
The North Pacific Rim harbors breeding populations of many unique wildlife resources, of which waterfowl are among the most abundant and taxonomically diverse. Arctic nesting geese in particular are wide-spread in distribution (Figure 1), and though only seasons residents, they have evolved many unique adaptations for breeding in northern latitudes....
