Use of electronarcosis to immobilize juvenile and adult northern pike
M.K. Walker, E.A. Yanke, W.H. Gingerich
1994, Progressive Fish-Culturist (56) 237-243
Electronarcosis, the immobilization of a fish after an electric current has been applied and discontinued, is a potential alternative to chemical anesthetics. Successful narcosis was defined as the immobilization of a fish for 1–15 min without causing physical damage. In the laboratory, AC successfully narcotized juvenile (13–19‐cm standard length, SL)...

Experimental studies of alunite: II. Rates of alunite-water alkali and isotope exchange
R.E. Stoffregen, R. O. Rye, M.D. Wasserman
1994, Geochimica et Cosmochimica Acta (58) 917-929
Rates of alkali exchange between alunite and water have been measured in hydrothermal experiments of 1 hour to 259 days duration at 150 to 400°C. Examination of run products by scanning electron microscope indicates that the reaction takes place by dissolution-reprecipitation. This exchange is modeled with an empirical rate equation...

Explosive tephra emissions of Mount St. Helens, 1989-1991: the violent escape of magmatic gas following storms?
L.G. Mastin
1994, Geological Society of America Bulletin (106) 175-185
From 24 August 1989 until 18 June 1991, Mount St. Helens produced at least 28 shallow, explosion-like seismic events with signatures similar to those produced by gas explosions on the dome during the mid 1980s. At least six were accompanied by violent emission of non-juvenile tephra, ejection of blocks of...
Rice seed toxicity tests for organic and inorganic substances
W. Wang
1994, Environmental Monitoring and Assessment (29) 101-107
Plant seed toxicity tests can be used to evaluate hazardous waste sites and to assess toxicity of complex effluents and industrial chemicals. Conventional plant seed toxicity tests are performed using culture dishes containing filter paper. Some reports indicate that filter papers might interfere with the toxicity of inorganic substances. In...

M.F. Orlando
1994, Open-File Report 94-339
The U.S. Geological Survey has 82 active or complete-except-report projects of hydrologic investigations ongoing within the New England Program Area. Of this total, 23 are data projects. Data projects contain statistics and data on the conditions of surface water, ground water, water quality and (or) water use for the study...
A toxic equivalency factor scale for polychlorinated dibenzofurans
M. Tysklind, D. Tillitt, L. Eriksson, K. Lundgren, C. Rappe
1994, Toxicological Sciences (22) 277-285
The ethoxyresorufin O-deethylase (EROD) induction of 20 polychiorinated dibenzofurans (PCDFs) was examined in the H4IIE rat hepatoma cell bioassay. The selection of the compounds tested was based on a multivariate chemical characterization laying the groundwork for covering the whole chemical series of PCDFs. The EROD induction...

1994, Diseases of Aquatic Organisms (19) 27-37
Only one-third of the Pacific hernng Clupea harengus pallasi expected to spawn in Prince William Sound (PWS), Alaska, USA, in sprlng 1993 were observed. Of these herring, 15 to 43 '% had external ulcers or subdermal hemorrhages of the skln and fins. A rhabdovirus identified as the North American strain...
Closing of the Midcontinent-Rift - a far-field effect on Grenvillian compression
W.F. Cannon
1994, Geology (22) 155-158
The Midcontinent rift formed in the Laurentian supercontinent between 1109 and 1094 Ma. Soon after rifting, stresses changed from extensional to compressional, and the central graben of the rift was partly inverted by thrusting on original extensional faults. Thrusting culminated at about 1060...
A water-renewal system that accurately delivers small volumes of water to exposure chambers
D. C. Zumwalt, F.J. Dwyer, I.E. Greer, C.G. Ingersoll
1994, Environmental Toxicology and Chemistry (13) 1311-1314
This paper describes a system that can accurately deliver small volumes of water (50 ml per cycle) to eight 300-ml beakers. The system is inexpensive <$100), easy to build (<8 h), and easy to calibrate (<15 min), and accurately delivers small volumes of water (<5% variability)....
Accumulation of 2,3,7,8-Tetrachlorodibenzo-p-dioxin equivalents by double-crested cormorant (Phalacrocorax auritus, Pelicaniformes) chicks in the North American Great Lakes

Concentrations of polychlorinated biphenyls (PCBs), and 2,3,7,8-tetrachlordibenzo-p-dioxin equivalents (TCDD-EQ) were determined in eggs and chicks of double-crested cormorants (DCC) which were collected in 1989 from eight locations in the Laurentian Great Lakes. The mean biomagnification factor (BMF) from forage fish to eggs was found to be 31.3. Absolute and relative...
Species diversity, selectivity, and habitat associations of small mammals from coastal California
Gary M. Fellers
1994, Southwestern Naturalist (39) 128-136
Species diversity and habitat associations were documented for small mammals along 16 transects in a semiarid part of coastal California. Peromyscus were the most abundant, comprising 45.3% of all captures, followed by Dipodomys (21.2%), Neotoma (15.1%), and Perognathus (15.0%). Five additional genera made up the remaining captures (3.4%). Peromyscus truei...
