Avulsion of the brachial plexus in a great horned owl (Bubo virginaus)
M.P. Moore, E. Stauber, N. J. Thomas
1989, Journal of Raptor Research (23) 3-9
Avulsion of the brachial plexus was documented in a Great Horned Owl (Bubo virginianus). A fractured scapula was also present. Cause of these injuries was not known but was thought to be due to trauma. Differentiation of musculoskeletal injury from peripheral nerve damage can be difficult in raptors. Use of...
Effects of fire in the Northern Great Plains
Kenneth F. Higgins, Arnold D. Kruse, James L. Piehl
1989, Report
This publication is a review of selected literature about prescribed burning in the Northern Great Plains (NGP) for management of wildlife. It also will be useful to other resource managers and researchers and to persons interested in the NGP. It is more 'descriptive' than 'interpretative.'The publication is a joint effort...
Vegetation of wetlands of the prairie pothole region
H.A. Kantrud, J.B. Millar, A.G. Van Der Valk
A. van der Valk, editor(s)
1989, Book chapter, Northern prairie wetlands
Five themes dominate the literature dealing with the vegetation of palustrine and lacustrine wetlands of the prairie pothole region: environmental conditions (water or moisture regime, salinity), agricultural disturbances (draining, grazing, burning, sedimentation, etc.), vegetation dynamics, zonation patterns, and classification of the wetlands.The flora of a prairie wetland is a function...
Distribution of alewives in southeastern Lake Ontario in autumn and winter: a clue to winter mortalities
Roger A. Bergstedt, Robert O’Gorman
1989, Transactions of the American Fisheries Society (118) 687-692
Alewives Alosa pseudoharengus in the Great Lakes are thought to avoid extreme cold in winter by moving to deep water where the temperature is usually highest because of inverse thermal stratification. Information collected in Lake Ontario during autumn and winter 1981–1984 with an echo sounder and bottom and midwater trawls indicated that...
Movements of striped mullet, Mugil cephalus, tagged in Everglades National Park, Florida
N.A. Funicelli, D.A. Meineke, H.E. Bryant, M. R. Dewey, G.M. Ludwig, L.S. Mengel
1989, Bulletin of Marine Science (44) 171-178
The movements of striped mullet, Mugil cephalus, were studied from fish tagged in Everglades National Park. Florida. A total of 16,604 fish were tagged from March 1984 to September 1985. During the period December 1984 through February 1985 recaptured tagged fish moved significantly further and more northerly out of the...
Artificial recharge to the Floridan aquifer system, Orlando Area, Central Florida
E. R. German, L. A. Bradner
1989, Conference Paper
Approximately 400 drainage wells exist in Orange County, central Florida. The rate of recharge through drainage wells is limited by the rate of surface flow to the wells; the hydraulic properties of weirs, overflow pipes, and well casings; or the water level above the top of the casing. The rate...
A high-resolution seismic reflection/refraction study of the Chugach-Peninsular terrane boundary, southern Alaska
T.M. Brocher, M. A. Fisher, E.L. Geist, N.I. Christensen
1989, Journal of Geophysical Research Solid Earth (94) 4441-4455
We present results from a high-resolution seismic refraction analysis of the shallow (approximately 2 km) crustal structure along the 107-km-long Trans-Alaska Crustal Transect Chugach reflection line in southern Alaska and a comparison with laboratory measurements of field samples. The refraction analysis includes the two-dimensional interpretation of several thousand first- and...
Changes in saltwater intrusion in the Biscayne aquifer, Hialeah-Miami Springs area, Dade County, Florida
Howard Klein, Karl W. Ratzlaff
1989, Water-Resources Investigations Report 87-4249
A lobe of salty groundwater that had intruded the Hialeah-Miami Springs area municipal well field, adjacent to the Miami and Tamiami Canals in Dade County, Florida, was stabilized after flow-regulation structures were installed in the canals in 1946. However, in 1971, the saltwater began to readvance toward the center of...
A macrophyte submodel for aquatic ecosystems
Carol Desormeau Collins, Joseph H. Wlosinski
1989, Aquatic Botany (33) 191-206
A macrophyte submodel has been incorporated and tested in CE-QUAL-R1, a one-dimensional, vertically averaged model of reservoir water quality. A quasi two-dimensional scheme was necessary to represent the spatial relationship of macrophytes in reservoirs adequately. The macrophyte processes modeled were photosynthesis, dark respiration, excretion and nonpredatory mortality. Process equations for...
Petrology and age of alkalic lava from the Ratak Chain of the Marshall Islands
A. S. Davis, M. S. Pringle, L.-B.G. Pickthorn, D.A. Clague, W. C. Schwab
1989, Journal of Geophysical Research Solid Earth (94) 5757-5774
Volcanic rock dredged from the flanks of four volcanic edifices in the Ratak chain of the Marshall Islands consist of alkalic lava that erupted above sea level or in shallow water. Compositions of recovered samples are predominantly differentiated alkalic basalt and hawaiite but include strongly alkalic melilitite. Whole rock 40Ar/39Ar total...
Pleistocene Suvero slide, Paola basin, southern Italy
F. Trincardi, W. R. Normark
1989, Marine and Petroleum Geology (6) 324-335
The Suvero slide covers an area of about 225 km2 in the Paola slope basin on the Eastern Tyrrhenian margin. The shape and lateral extent of the deposit reflect topographic confinement of the slide between the continental slope and a morphologic barrier formed by a margin-parallel slope ridge. No headwall...
Geochemical controls on vanadium accumulation in fossil fuels
G. N. Breit, R. B. Wanty
1989, Conference Paper, Preprints Symposia
High vanadium contents in petroleum and other fossil fuels have been attributed to organic-matter type, organisms, volcanic emanations, diffusion of sea water, and epigenetic enrichment. However, these factors are inadequate to account for the high abundance of vanadium in some fossil fuels and the paucity in others. By examining vanadium...
High-precision UPb ages of metamorphic rutile: Application to the cooling history of high-grade terranes
K. Mezger, G. N. Hanson, S.R. Bohlen
1989, Earth and Planetary Science Letters (96) 106-118
Metamorphic rutiles occurring in granulite and upper amphibolite facies metapelitic rocks of the Archean Pikwitonei granulite domain (Manitoba) and the Proterozoic Adirondack terrane (New York) give concordant and near concordant UPb ages. The Pb concentrations in rutile range from 2.85 to 168 ppm, U concentrations range...
