Morphology of glochidia of Lampsilis higginsi (Bivalvia: Unionidae) compared with three related species
D. L. Waller, L. E. Holland Bartels, L. G. Mitchell
1988, American Malacological Bulletin (6) 39-43
Glochidia of the endangered unionid mussel Lampsilis higginsi (Lea) are morphologically similar to those of several other species in the upper Mississippi River. Life history details, such as the timing of reproduction and identity of host fish, can be readily studied if the glochidia of L. higginsi...
Fish hosts for glochidia of the endangered freshwater mussel Lampsilis higginsi Lea (Bivalvia: Unionidae)
D. L. Waller, L. E. Holland Bartels
1988, Malacological Review (21) 119-122
Laboratory tests of nine species of fish as hosts for glochidia of Lampsilis higginsi Lea indicated that four species were fully suitable: largemouth bass (Micropterus salmoides Lacepede), smallmouth bass (M. dolomieui Lacepede), walleye (Stizostedion vitreum vitreum Mitchill), and yellow perch (Perca flavescens Mitchill)....
High-performance liquid-chromatographic separation of subcomponents of antimycin-A
S. L. Abidi
1988, Journal of Chromatography (447) 65-79
Using a reversed-phase high-performance liquid chromatographic (HPLC) technique, a mixture of antimycins A was separated into eight hitherto unreported subcomponents, A1a, A1b, A2a, A2b, A3a, A3b, A4a, and A4b. Although a base-line resolution of the known four major antimycins A1, A2, A3, and A4 was readily achieved with mobile phases containing...
Residues of benzocaine in rainbow trout, largemouth bass, and fish meal
J. L. Allen
1988, Progressive Fish-Culturist (50) 59-60
Residues of the anesthetic benzocaine in muscle tissue of rainbow trout (Salmo gairdneri) and largemouth bass (Micropterus salmoides) were determined after exposure of the fish to 50 mg benzocaine/L for 15 min and withdrawal times of 0–24 h. The mean concentration of benzocaine residues in fish sampled immediately after exposure...
Resonance of a fluid-driven crack: Radiation properties and implications for the source of long-period events and harmonic tremor
B. Chouet
1988, Journal of Geophysical Research Solid Earth (93) 4375-4400
A dynamic source model is presented, in which a three-dimensional crack containing a viscous compressible fluid is excited into resonance by an impulsive pressure transient applied over a small area ΔS of the crack surface. The crack excitation depends critically on two dimensionless parameters called the crack stiffness, C = (b/μ)(L/d), and...
Lateral fluid flow in a compacting sand-shale sequence: South Caspian basin
John D. Bredehoeft, R. D. Djevanshir, Kenneth Belitz
1988, American Association of Petroleum Geologists Bulletin (72) 416-424
The South Caspian basin contains both sands and shales that have pore-fluid pressures substantially in excess of hydrostatic fluid pressure. Pore-pressure data from the South Caspian basin demonstrate that large differences in excess hydraulic head exist between sand and shale. The data indicate that sands are acting as drains for...
Deformation in the Yakataga seismic gap, Southern Alaska, 1980-1986
J.C. Savage, M. Lisowski
1988, Journal of Geophysical Research Solid Earth (93) 4731-4744
A 60-by-40-km trilateration network in the Yakataga seismic gap was surveyed in 1980, 1982, 1984, and 1986 with precise electro-optical distance-measuring equipment to measure strain accumulation. The overall deformation is roughly approximated by a 0.24±0.03 µstrain/yr N32°W±2.4° uniaxial contraction that is uniform in time. However, the spatial distribution of deformation...
Parkfield, California, liquefaction prediction (USA)
T.L. Holzer, M.J. Bennett, T. L. Youd, A.T.F. Chen
1988, Bulletin of the Seismological Society of America (78) 385-389
The primary purpose of this short note is to formally record the liquefaction prediction (Holzer et al., 1986) made in connection with this predicted earthquake. In addition, this note serves to alert the seismic engineering community to special instrumentation being installed at the prediction site. The instrumentation will consist of...
Origin of metaluminous and alkaline volcanic rocks of the Latir volcanic field, northern Rio Grande rift, New Mexico
C.M. Johnson, P. W. Lipman
1988, Contributions to Mineralogy and Petrology (100) 107-128
Volcanic rocks of the Latir volcanic field evolved in an open system by crystal fractionation, magma mixing, and crustal assimilation. Early high-SiO2 rhyolites (28.5 Ma) fractionated from intermediate compositionmagmas that did not reach the surface. Most precaldera lavas have intermediate-compositions, from olivine basaltic-andesite (53% SiO2) to quartz latite (67% SiO2)....

Feeding ecology of canvasbacks staging on Pool 7 of the Upper Mississippi River

1988, Book chapter, Waterfowl in winter
Foods consumed by canvasback ducks (Aythya valisineria), food availability, and energetic relationships were studied on Navigation Pool 7 of the upper Mississippi River in 1978, 1979, and 1980. Canvasbacks fed primarily upon winter buds of American wildcelery (Vallisneria americana) and tubers of stiff arrowhead (Sagittaria rigida). In 1980, waterfowl consumed...

Seasonal growth and occurrence of an exotic submersed aquatic macrophyte, Nitellopsis obtusa, was monitored at the head of the Detroit River of the Great Lakes from June 1984 to April 1985.Nitellopsis obtusa first appeared in early July, increased in biomass from July to September, remained at relatively high biomass from September to...
