Effects of management practices on grassland birds: Grasshopper Sparrow
Jill A. Dechant, Marriah L. Sondreal, Douglas H. Johnson, Lawrence D. Igl, Christopher M. Goldade, Melvin P. Nenneman, Betty R. Euliss
1998, Report, Effects of management practices on grassland birds
Information on the habitat requirements and effects of habitat management on grassland birds were summarized from information in more than 5,500 published and unpublished papers. A range map is provided to indicate the relative densities of the species in North America, based on Breeding Bird Survey (BBS) data. Although birds...

Waterfowl in the prairie pothole region
Jane E. Austin
M. J. Mac, P.A. Opler, C. E. Puckett Haecker, P.D. Doran, editor(s)
1998, Book chapter, Status and trends of the nation's biological resources
The prairie pothole region of the northern Great Plains is one of the most important areas for duck reproduction in North America. The region produces, on average, 50% of the primary species of game ducks on the continent (Smith 1995), yet accounts for only 10% of the waterfowl breeding habitat...
Effect of temperature on the pharmacokinetics of benzocaine in rainbow trout (Oncorhynchus mykiss) after bath exposures
G. R. Stehly, J.R. Meinertz, W.H. Gingerich
1998, Journal of Veterinary Pharmacology and Therapeutics (21) 121-127
The pharmacokinetics of benzocaine during bath exposures at 1 mg/L were determined in rainbow trout acclimated at 6 °C, 12 °C or 18 °C for at least 1 month. Individual fish were exposed to benzocaine in a recirculating system for 4 h and pharmacokinetic parameters were estimated in a unique...
Trilobites from Lower Mississippian starved basin facies of the southern United States
D. K. Brezinski
1998, Journal of Paleontology (72) 718-725
A distinctive trilobite fauna occurs within condensed stratigraphic sections of the Lower Mississippian (Tournaisian) Chappel Limestone of the Llano region of Texas, the Welden Limestone of Oklahoma, and the Chouteau Limestone of Union County, Illinois. The seven species comprising this fauna are interpreted...
Sulfur contents and sulfur-isotope compositions of thiotrophic symbioses in bivalve molluscs and vestimentiferan worms
R.D. Vetter, B. Fry
1998, Marine Biology (132) 453-460
Total sulfur (S(TOT)), elemental sulfur (S??) and sulfur-isotope compositions (??34S) of marine animals were analyzed to determine whether these chemical characteristics could help distinguish animals with a sulfur-based, thiotrophic nutrition from animals whose nutrition is based on methanotrophy or on more normal consumption of phytoplankton-derived organic matter. The presence of...
A new device for collecting time-integrated water samples from springs and surface water bodies
S.V. Panno, I.G. Krapac, D.A. Keefer
1998, Environmental & Engineering Geoscience (4) 375-383
A new device termed the 'seepage sampler' was developed to collect representative water samples from springs, streams, and other surface-water bodies. The sampler collects composite, time-integrated water samples over short (hours) or extended (weeks) periods without causing significant changes to the chemical composition of the samples. The water sample within...
Detection of aquifer system compaction and land subsidence using interferometric synthetic aperture radar, Antelope Valley, Mojave Desert, California
D. L. Galloway, K.W. Hudnut, S. E. Ingebritsen, S.P. Phillips, G. Peltzer, F. Rogez, P.A. Rosen
1998, Water Resources Research (34) 2573-2585
Interferometric synthetic aperture radar (InSAR) has great potential to detect and quantify land subsidence caused by aquifer system compaction. InSAR maps with high spatial detail and resolution of range displacement (±10 mm in change of land surface elevation) were developed for a groundwater basin (∼103 km2) in Antelope Valley, California, using...
Seismic image of a CO2 reservoir beneath a seismically active volcano
B.R. Julian, A.D. Pitt, G.R. Foulger
1998, Geophysical Journal International (133) F7-F10
Mammoth Mountain is a seismically active volcano 200 000 to 50 000 years old, situated on the southwestern rim of Long Valley caldera, California. Since 1989 it has shown evidence of unrest in the form of earthquake swarms (Hill et al. 1990), volcanic ‘long-period’ earthquakes...
