Chironomidae of the southeastern United States: a checklist of species and notes on biology, distribution, and habitat
Patrick L. Hudson, David R. Lenat, Broughton A. Caldwell, David Smith
1990, Fish and Wildlife Research 7
We provide a current listing of the species of midges (Diptera:Chironomidae) in the southeastern United States (Alabama, Florida, Georgia, North Carolina, South Carolina, and Tennessee). This checklist should aid research on this group of insects, which have often proved useful in the assessment of water quality. We document each species'...

1989, Book chapter, Proceedings of the Northeast Raptor Management Symposium and Workshop.
The snowy owl is a rare to uncommon, irregular winter visitor in the northeastern United States, decreasing southward in abundance except during incursion years, when it is more common and widely distributed. Although snowy owls are recorded in northern New England every winter, major incursions occur at approximately three...

Origin of Sr, Nd and Pb isotopic systematics in high-Sr basalts from central Arizona
J.H. Wittke, D. Smith, J. L. Wooden
1989, Contributions to Mineralogy and Petrology (101) 57-68
Alkalic and tholeiitic basalts were erupted in the central Arizona Transition Zone during Miocene-Pliocene time before and after regional faulting. The alkalic lava types differ from the subalkaline lavas in Sr, Nd and Pb isotopic ratios and trace element ratios and, despite close temporal and spatial relationships, the two types...
Whooping crane recovery: Progress through research
J.W. Carpenter, D.G. Smith
1988, Zooview (22) 5
Cooperative efforts of the Canadian Wildlife Service (CWS), U.S. Fish and Wildlife Service (FWS), Wood Buffalo National Park in Canada, and Patuxent Wildlife Research Center have established a captive flock of whooping cranes, and at least two additional wild populations. Efforts have focused on research, habitat protection, law enforcement,...
Raptors and aircraft

1988, Book chapter, Proceedings of the Southwest Raptor Management Symposium and Workshop
Less than 5% of all bird strikes of aircraft are by raptor species, but damage to airframe structure or jet engine dysfunction are likely consequences. Beneficial aircraft-raptor interactions include the use of raptor species to frighten unwanted birds from airport areas and the use of aircraft to census raptor species....
Crested caracara
D. H. Ellis, D.G. Smith, W.H. Whaley, Catherine H. Ellis
Richard L. Glinski, Beth Giron Pendleton, Mary Beth Moss, Maurice N.= LeFranc Jr., Brian A. Millsap, Stephen W. Hoffman, editor(s)
1988, Book chapter, Proceedings of the Southwest Raptor Management Symposium and Workshop.
The crested caracara's range extends from the southern United States south to Tierra del Fuego. Although the caracara has been recorded in all of the southwestern states, it occurs regularly only in southern Arizona and central, southern and coastal Texas. Its distribution is closely linked to the availability of carrion....
Geohydrology and digital simulation of the ground-water flow system in the Umatilla Plateau and Horse Heaven Hills area, Oregon and Washington
A. Davies-Smith, E.L. Bolke, C. A. Collins
1988, Water-Resources Investigations Report 87-4268
The Columbia Plateau is underlain by massive basalt flows, with a composite thickness of about 10,000 ft. Structural features within the study area include a series of anticline-syncline pairs. The main avenues of groundwater movement in the basalt are the interflow zone between basalt flows. Individual interflow zones may be...

The U.S. Geological Survey has conducted geochemical studies in the Indian Pass (CDCA-355), 124 km2, and Picacho Peak (CDCA-355A), 23 km2, Wilderness Study Areas (WSA's) as part of a program to evaluate the mineral resource potential of designated areas in the California Desert Conservation Area. These two WSA's are of...
Evaluation of the improvement in sensitivity of nested frequency plots to vegetational change by summation
Stuart D. Smith, Stephen C. Bunting, M. Hironaka
1987, Western North American Naturalist (47) 299-307
At four sites in Idaho, frequency was measured separately with three different-sized plots (10 x 25, 15 x 33.5, and 20 x 50 cm) arranged in a nested configuration. These individual frequency values were added together to create a summed “frequency.” This summed value was compared to the original frequency...
