Wildlife association with human‐altered water sources in semiarid vegetation communities
D.W. Burkett, B.C. Thompson
1994, Conservation Biology (8) 682-690
Based on common use in wildlife management, we hypothesized that human‐constructed water sources influence faunal communities detectably compared to similar habitats that lack water. We examined 20 wildlife water units and 20 paired comparison sites without water from April to August 1992 in semiarid southern New Mexico to assess animal...
Characterization of the glycoprotein of infectious hematopoietic necrosis virus using neutralizing monoclonal antibodies
Chienjin Huang, Maw-Sheng Chien, Marsha Landolt, James Winton
1994, Diseases of Aquatic Organisms (18) 29-35
To study the antigenic nature of the glycoprotein (G protein) of infectious hematopoietic necrosis virus (IHNV), 31 neutralizing monoclonal antibodies (MAbs) were produced against a reference isolate of the virus. The MAbs were compared using a neutralization assay, an enzyme-linked immunosorbent assay (ELISA), and by immunoblotting of the G protein...
High-precision 40Ar/39Ar age spectrum dating of sanidine from the Middle Pennsylvanian Fire Clay tonstein of the Appalachian basin
Michael J. Kunk, Charles L. Rice
1994, GSA Special Papers (294) 105-112
40Ar/39Ar plateau age spectra of seven sanidine samples from the Fire Clay tonstein (Middle Pennsylvanian), collected along a 300-km traverse in the Appalachian basin, range from 310.3 to 311.4 Ma. All plateau ages agree, within the limits of analytical precision, with their respective total gas ages. This agreement, together with...
40Ar 39Ar age constraints on neogene sedimentary beds, Upper Ramparts, half-way Pillar and Canyon village sites, Porcupine river, east-central Alaska
Michael J. Kunk, H. Rieck, T. D. Fouch, L. David Carter
1994, Quaternary International (22-23) 31-42
40Ar/39Ar ages of volcanic rocks are used to provide numerical constraints on the age of middle and upper Miocene sedimentary strata collected along the Porcupine River. Intercalated sedimentary rocks north of latitude 67°10′N in the Porcupine terrane of east-central Alaska contain a rich record of plant fossils. The fossils are valuable...
Fate and pathways of injection-well effluent in the Florida Keys
Eugene A. Shinn, Ronald S. Reese, Christopher D. Reich
1994, Open-File Report 94-276
Twenty-four wells (21 locations) were core drilled into the limestone beneath the Keys, reef tract, and outer reefs to determine if sewage effluents injected in Class V wells onshore are reaching offshore reef areas via underground flow. These wells were fitted with PVC casings and well screens and were...

1994, Book, Computers in mineral industry
Overcoming future difficulties in searching for ore deposits deeper in the earth's crust will require closer attention to the collection and analysis of more diverse types of data and to more efficient use of current computer technologies. Computer technologies of greatest interest include methods of storage and retrieval of resource...

1994, International Journal of Remote Sensing (15) 3443-3462
The global land 1 km data set project represents an international effort to acquire, archive, process, and distribute 1 km AVHRR data of the entire global land surface in order to meet the needs of the international science community. A network of 26 high resolution picture transmission (HRPT) stations, along...
Straight-line drift fences and pitfall traps
Paul Stephen Corn
1994, Book chapter, Measuring and monitoring biological diversity: standard methods for amphibians
Straight-line drift fences typically are short barriers (5-15 m) that direct animals traveling on the substrate surface into traps places at the ends of or beside the barriers. Traps (described below) can be pitfalls, funnel traps, or a combination of the two. Drift fences with pitfall or funnel traps and...
Neural networks for river flow prediction
Nachimuthu Karunanithi, William J. Grenney, Darrell Whitley, Ken Bovee
1994, Journal of Computing in Civil Engineering (8) 201-203
The surface‐water hydrographs of rivers exhibit large variations due to many natural phenomena. One of the most commonly used approaches for interpolating and extending streamflow records is to fit observed data with an analytic power model. However, such analytic models may not adequately represent the flow process, because they are...
Chromatographic (TLC) differentiation of grizzly bear and black bear scats
Harold D. Picton, Katherine C. Kendall
1994, Bears: Their Biology and Management (9) 497-501
While past work concluded that thin-layer chromatography (TLC) was inadequate for the separation of grizzly (Ursus arctos horribilis) and black bear (U. americanus) scats, our study found differences adequate for species separation. A key was constructed using 19 of 40 data points recorded on each(N)=356 profiles of 178) know-species...

Most of the conodont data presented in this report (table 1) were acquired to support 1:100,000-scale geologic mapping of the Winchester 30' X 60' quadrangle by the U.S. Geological Survey (USGS). Conodonts were chosen to provide a biostratigraphic framework for the Upper Cambrian to Mississippian marine carbonate rocks that make...
Seismicity trends and potential for large earthquakes in the Alaska-Aleutian region
C. G. Bufe, S.P. Nishenko, D. J. Varnes
1994, Pure and Applied Geophysics PAGEOPH (142) 83-99
The high likelihood of a gap-filling thrust earthquake in the Alaska subduction zone within this decade is indicated by two independent methods: analysis of historic earthquake recurrence data and time-to-failure analysis applied to recent decades of instrumental data. Recent (May 1993) earthquake activity in the Shumagin Islands gap is consistent...
Potential-field sounding using Euler's homogeneity equation and Zidarov bubbling
Lindrith Cordell
1994, Geophysics (59) 902-908
Potential-field (gravity) data are transformed into a physical-property (density) distribution in a lower half-space, constrained solely by assumed upper bounds on physical-property contrast and data error. A two-step process is involved. The data are first transformed to an equivalent set of line (2-D case) or point (3-D case) sources, using...

Relation between largest known flood discharge and elevation in Montana
Charles Parrett, Stephen R. Holnbeck
1994, Conference Paper, Proceedings - National Conference on Hydraulic Engineering
Previous studies relating unit discharge to elevation indicated that large floods in the Rocky Mountains may be limited by elevation. However, high-elevation data are sparse in Montana and the indications may not be entirely correct. Based on data at 19 sites in Montana, a strong log-linear relation exists between large-flood...

R. J. Omang
1994, Water-Resources Investigations Report 93-4215
Hydrologic and hydraulic evaluations of Muddy Creek were made to determine the magnitude of the 100-year flood and the extent of flooding that would occur as the result of this flood. Forty-three cross sections were surveyed and 14 cross sections were synthesized along a 6.7-mile reach of Muddy Creek. Data...
