Preservation of genetic variation in the Green Lake strain lake trout derived from remnant domestic and feral populations
H. L. Kincaid, C.C. Krueger, B. May
1993, North American Journal of Fisheries Management (13) 318-325
The Green Lake, Wisconsin, strain of lake trout Salvelinus namaycush was discontinued as a hatchery brood stock in 1976 after Lake Michigan was stocked with the 1975 year‐class. In 1982, a decision was made to restore the Green Lake strain as a production brood stock. Five groups were produced by spawning marked...
Genetic comparison of naturally spawned and artificially propagated Lake Ontario lake trout fry: Evaluation of a stocking strategy for species rehabilitation
J.E. Marsden, C.C. Krueger, P.M. Grewe, H. L. Kincaid, B. May
1993, North American Journal of Fisheries Management (13) 304-317
Two strategies have been used in the effort to restore lake trout Salvelinus namaycush to Lake Ontario. First, lake trout strains from multiple wild and hatchery sources have been stocked to maximize genetic variability in the lake, Second, a unique hatchery “strain” of fish to be stocked was created each year with...
Sampling colloids and colloid-associated contaminants in ground water
Debera A. Backhus, Joseph N. Ryan, Daniel M. Groher, John K. MacFarlane, Philip M. Gschwend
1993, Groundwater (31) 466-479
It has recently been recognized that mobile colloids may affect the transport of contaminants in ground water. To determine the significance of this process, knowledge of both the total mobile load (dissolved + colloid-associated) and the dissolved concentration of a ground-water contaminant must be obtained. Additional information regarding mobile colloid...
Comparison of Penman-Monteith, Shuttleworth-Wallace, and modified Priestley-Taylor evapotranspiration models for wildland vegetation in semiarid rangeland
David I. Stannard
1993, Water Resources Research (29) 1379-1392
Eddy correlation measurements of sensible and latent heat flux are used with measurements of net radiation, soil heat flux, and other micrometeorological variables to develop the Penman-Monteith, Shuttleworth-Wallace, and modified Priestley-Taylor evapotranspiration models for use in a sparsely vegetated, semiarid rangeland. The Penman-Monteith model, a one-component model designed for use...
Broad trends in geomagnetic paleointensity on Hawaii during Holocene time
Edward A. Mankinen, Duane E. Champion
1993, Journal of Geophysical Research B: Solid Earth (98) 7959-7976
Paleointensity determinations have been obtained from 22 basaltic lava flows on the island of Hawaii using the Thelliers' method. Radiocarbon dating indicates that these flows erupted at intervals ranging from about 200 to 1000 years, and results of the experiments provide an estimate of broad trends in geomagnetic paleointensity during...
Volitional migration of Atlantic salmon from seasonal holding ponds
S. Rottenborn, Lori A. Redell
1993, North American Journal of Fisheries Management (13) 238-252
For 5 years we used seawater tolerance tests (seawater challenges) to identify smolts, and tunnel fish counters to record the time of migration, of Atlantic salmon Salmo salar that volitionally left holding ponds on the Merrimack River near Litchfield, New Hampshire. We compared timing of Atlantic salmon movements with environmental conditions and...

K. P. Gallo, A. L. McNab, Thomas R. Karl, Jesslyn F. Brown, J. J. Hood, J.D. Tarpley
1993, Journal of Applied Meteorology and Climatology (32) 899-908
A vegetation index and a radiative surface temperature were derived from satellite data acquired at approximately 1330 LST for each of 37 cities and for their respective nearby rural regions from 28 June through 8 August 1991. Urbanrural differences for the vegetation index and the surface temperatures were computed and...
Determination of buoyant density and sensitivity to chloroform and freon for the etiological agent of infectious salmonid anaemia
K.E. Christie, B. Hjeltnes, I. Uglenes, J. R. Winton
1993, Diseases of Aquatic Organisms (15) 225-228
Plasma was collected from Atlantic salmon Salrno salar with acute infectious salmon anaemia (ISA) and used to challenge Atlantic salmon parr by intraperitoneal injection. Treatment of plasma with the lipid solvent, chloroform, showed that the etiological agent of ISA contained essential lipids, probably as a viral envelope. Some infectivity remained...

Paleoseismology along the 1980 surface rupture of the Irpinia Fault: Implications for earthquake recurrence in the southern Apennines, Italy
D. Pantosti, David P. Schwartz, Gianluca Valensise
1993, Journal of Geophysical Research B: Solid Earth (98) 6561-6577
The Irpinia fault was the source of the Ms 6.9 1980 Irpinia earthquake and produced the first unequivocal historical surface faulting in Italy. Trenching of the 1980 fault scarp at Piano di Pecore, a flat intermontane basin about 5 km south of the 1980 instrumental epicenter, provides the first data on earthquake...
Effects of hydrothermal alteration on the magnetization of the Oligocene Carpenter Ridge Tuff, Bachelor Caldera, San Juan Mountains, Colorado
Donald S. Sweetkind, Richard L. Reynolds, David A. Sawyer, Joseph G. Rosenbaum
1993, Journal of Geophysical Research B: Solid Earth (98) 6255-6266
Intracaldera Oligocene Carpenter Ridge Tuff fills the Bachelor caldera in the central San Juan caldera complex and hosts mineral deposits of the Creede mineral district. The Carpenter Ridge Tuff and unaltered portions of its intracaldera Bachelor Mountain Member, have strong, high‐coercivity, reverse magnetizations with average magnetic susceptibility (MS) and natural...
Coseismic displacements: 1992 Landers, California, earthquake
M.H. Murray, J.C. Savage, M. Lisowski, W.K. Gross
1993, Geophysical Research Letters (20) 623-626
The rupture associated with the 1992 Landers earthquake (Ms = 7.5) extended along the west edge of a 60 × 50 km trilateration network that had been surveyed two months before the earthquake and was resurveyed a month after it. The coseismic displacement field within the network was calculated from...

The Landers earthquake, which had a moment magnitude (Mw) of 7.3, was the largest earthquake to strike the contiguous United States in 40 years. This earthquake resulted from the rupture of five major and many minor right-lateral faults near the southern end of the eastern California shear zone, just north...

William J. Lutter, Anne M. Trehu, Robert L. Nowack
1993, Geophysical Research Letters (20) 615-618
The inversion technique of Nowack and Lutter (1988a) and Lutter et al.

Edge-driven microplate kinematics
Hans Schouten, Kim D. Klitgord, David G. Gallo
1993, Journal of Geophysical Research B: Solid Earth (98) 6689-6701
It is known from plate tectonic reconstructions that oceanic microplates undergo rapid rotation about a vertical axis and that the instantaneous rotation axes describing the microplate's motion relative to the bounding major plates are frequently located close to its margins with those plates, close to the tips of propagating rifts....

L. David Mech, Thomas J. Meier, Ulysses S. Seal
1993, American Midland Naturalist (129) 266-271
We measured nipple sizes of 29 captive wolves (Canis lupus), of known breeding histories, throughout the year and tested distinctions among various known breeding statuses of 20 wild wolves examined in northeastern Minnesota from May through September. For ca. 8 mo of the year only breeders and nonbreeders can be...

Severe earthquakes of the last decade in Mexico, Armenia, and the United States have reemphasized the importance of local geologic site conditions in estimating damage and consequent losses. Recent advances in geographic information system (GIS) technology have created new opportunities for maintaining and integrating extensive spatial databases for applications in...
Wetland modeling and information needs at Stillwater National Wildlife Refuge
David B. Hamilton, Gregor T. Auble
1993, Report, Results of a workshop sponsored by Division on Wildlife Refuges and Wildlife, Region 1
The marshes in and around Stillwater National Wildlife Refuge (the Refuge) are extremely dynamic; expanding and contracting in size both seasonally, due to runoff and subsequent evapotranspiration, and over longer periods, due to climatic variation. The dynamic nature of these marshes results in a diversity of wetland habitats, which...
