1991, Xenobiotica (21) 525-533
1. Branchial and urinary elimination of benzocaine residues was evaluated in adult rainbow trout, oncorhynchus mykiss, given a single dorsal aortic dose of c-14-benzocaine hydrochloride.^2. Branchial elimination of benzocaine residues was rapid and accounted for 59.2% Of the dose during the first 3 h after dosing. Renal...
The effects of noise due to random undetected tilts and paleosecular variation on regional paleomagnetic directions
G.J. Calderone, R.F. Butler
1991, Journal of Geophysical Research (96) 3973-3977
Random tilting of a single paleomagnetic vector produces a distribution of vectors which is not rotationally symmetric about the original vector and therefore not Fisherian. Monte Carlo simulations were performed on two types of vector distributions: (1) distributions of vectors formed by perturbing a single...

S.P. Nishenko
1991, Pure and Applied Geophysics PAGEOPH (135) 169-259
The seismic potential for 96 segments of simple plate boundaries around the circum-Pacific region is presented in terms of the conditional probability for the occurrence of either large or great interplate earthquakes during the next 5, 10, and 20 years (i.e., 1989-1994, 1989-1999 and 1989-2009). This study represents the first...
Effects of uranium mining, Puerco River, New Mexico
Thomas J. Lopes
1991, Conference Paper
Effluent from uranium-mine dewatering and acidic water released by a tailings-pond dike failure increased radionuclide activities in streamflow in the Puerco River in New Mexico and Arizona. Median dissolved gross-alpha activity in the streamflow was 1,130 picocuries per liter from 1975 to 1986 when mine discharges ceased and 6.2 picocuries...

1991, Conference Paper, Proceedings - National Conference on Hydraulic Engineering
A series of projections of climate change were applied to a watershed model of the Delaware River basin to identify sources of uncertainty in predicting effects of climate change on drought in the basin as defined by New York City reservoir contents. The watershed model is a calibrated, monthly time-step...
Assessing the effects of microbial metabolism and metabolities on reservoir pore structure
E.O. Udegbunam, J.P. Adkins, R.M. Knapp, M.J. McInerney, R.S. Tanner
1991, Conference Paper, Proceedings - SPE Annual Technical Conference and Exhibition
The effect of microbial treatment on pore structure of sandstone and carbonatereservoirs was determined. Understanding how different bacterial strains and their metabolic bioproducts affect reservoir pore structure will permit the prudent application of microorganisms for enhanced oil recovery. The microbial strains tested included Clostridium acetobutylicum, a polymer-producing Bacillus strain, and...
Seasonal patterns of prey availability and the foraging behavior of arctic foxes (Alopex lagopus) in a waterfowl nesting area
Alice Stickney
1991, Canadian Journal of Zoology (69) 2853-2859
The foraging behavior of arctic foxes was observed in a waterfowl nesting area on the Yukon–Kuskokwim Delta of Alaska in 1985–1986. Observations were made during peak fox activity from two towers, 3 m high, located in different community types. Data were collected continuously for individual foxes on specific activities, the community...

We found Compsopogon cf. coeruleus for the first time in the Laurentian Great Lakes, growing on limestone rocks at a depth of 21 m on Six Fathom Bank in central Lake Huron. It is the first freshwater red alga to be found in the Great Lakes and the only red alga ever found on an...

Digestibility and energy values of intact, disrupted and extracts from brewer's dried yeast fed to rainbow trout (Oncorhynchus mykiss)
G. L. Rumsey, S. G. Hughes, R. R. Smith, J.E. Kinsella, K. J. Shetty
1991, Animal Feed Science and Technology (33) 185-193
Although fish meal has historically been used as the primary source of protein in fish feeds, brewer's dried yeast (BDY) is presently being investigated as a primary replacement for fish meal. As little is known about the ability of fish to utilize BDY, studies were conducted to study bioavailability of...

Growth rate is negatively correlated with hatch date in Black Brant
James S. Sedinger, Paul L. Flint
1991, Ecology (72) 496-502
Arctic geese nest in a highly seasonal environment in which ungrazed plants reach peak nitrogen concentrations when goslings hatch (Sedinger and Raveling 1986). Grazing by geese prolongs peak nutrient concentrations but reduces food availability. This should cause nutrient availability to decline seasonally. Here, we test the hypothesis that late-hatching goslings...
The Vigil Network: A means of observing landscape change in drainage basins
W. R. Osterkamp, W. W. Emmett, Luna Bergere Leopold
1991, Hydrological Sciences Journal (36) 331-344
Long-term monitoring of geomorphic, hydrological, and biological characteristics of landscapes provides an effective means of relating observed change to possible causes of the change. Identification of changes in basin characteristics, especially in arid areas where the response to altered climate or land use is generally rapid and readily apparent, might...
Estimating estuarine flushing and residence times in Charlotte Harbor, Florida, via salt balance and a box model
R. L. Miller, B. F. McPherson
1991, Limnology and Oceanography (36) 602-612
The new concept is that, over many tidal cycles, the tidally averaged "flow' (Qg) of water from the Gulf of Mexico, with a salinity of 35???, can be treated as a constant at any point in the estuary. This flow is used in a simple mixing equation to predict salinity...

Distribution patterns of individually identifiable West Indian manatees (Trichechus manatus) in Florida
J.P. Reid, G. B. Rathbun, J.R. Wilcox
1991, Marine Mammal Science (7) 180-190
Photographs of distinctively scarred manatees (Trichechus manatus) were taken at aggregation sites throughout Florida and assembled into a catalog for identifying individuals. Resightings of known manatees in different years or at different locations enabled us to document site fidelity and long-distance movements. Of the 891 individuals included in the catalog...
Use of lupflour as a replacement for full-fat soy diets for rainbow trout (Oncorhynchus mykiss)
S. G. Hughes
1991, Aquaculture (93) 57-62
A 12-week feeding study was conducted to determine if either whole or dehulled lupin flour could be used as an economical replacement for full-fat soybean meal (FFSM) in a ration for rainbow trout (Oncorhynchus mykiss) and to determine if it was necessary to replace the soybean oil lost when FFSM...
Effect of high dietary concentrations of brewer's dried yeast on growth performance and liver uricase in rainbow trout (Oncorhynchus mykiss)
G. L. Rumsey, J.E. Kinsella, K. J. Shetty, S. G. Hughes
1991, Animal Feed Science and Technology (33) 177-183
The potential of using yeast nitrogen in fish feeds to replace proteins from conventional sources is an attractive option to nutritionists, feed manufacturers and fish farmers. Experiments were conducted to determine the effects of high dietary levels of brewer's dried yeast, with 20% of its protein represented by nucleic acid...
Inter- and intraspecific mitochondrial DNA variation in North American bears (Ursus)
Matthew A. Cronin, Steven C. Amstrup, Gerald W. Garner, Ernest R. Vyse
1991, Canadian Journal of Zoology (69) 2985-2992
We assessed mitochondrial DNA variation in North American black bears (Ursus americanus), brown bears (Ursus arctos), and polar bears (Ursus maritimus). Divergent mitochondrial DNA haplotypes (0.05 base substitutions per nucleotide) were identified in populations of black bears from Montana and Oregon. In contrast, very similar haplotypes occur in black bears...

1991, Journal of Wildlife Management (55) 160-171
t: We used 10 Telonics ST-3 platform transmitter terminals (PTT's) configured for wolves and ungulates to examine the performance of the Argos satellite telemetry system. Under near-optimal conditions, 68 percentile errors for location qualities (NQ) 1, 2, and 3 were 1,188, 903, and 361 m, respectively. Errors (rE) exceeded expected...
An epizootic of Florida manatees associated with a dinoflagellate bloom
T. J. O'Shea, G. B. Rathbun, R. K. Bonde, C.D. Buergelt, D.K. Odell
1991, Marine Mammal Science (7) 165-179
Over a 10-wk period in early 1982, 39 Florida manatees (Trichechus manatus latirostris) were found dead in the lower Caloosahatchee River and nearby waters of southwestern Florida. Two were killed by boats. The remainder showed no evidence of trauma. Lesions indicative of infectious agents were not identified, and bacteriological and...
