Fishes in mangrove prop-root habitats of northeastern Florida Bay: Distinct assemblages across an estuarine gradient
J.A. Ley, Carole McIvor, C.L. Montague
1999, Estuarine, Coastal and Shelf Science (48) 701-723
Seasonal changes in freshwater inflow and other environmental conditions may induce changes in density and species composition of mangrove fishes along estuarine gradients. Fishes within mangrove habitats in a subtropical estuary were sampled monthly from May 1989 to May 1990, using block nets with rotenone and visual censuses. At 18...

Large sediment deposits on the reef front around Oahu are a possible resource for replenishing eroded beaches. An overview is given on the collection of closely spaced, high-resolution subbottom profiles that clearly depict the deposits in three areas, namely, the Kailua Bay off the windward coast, Makua to Kahe Point...
Behavioral correlates of heart rates of free-living Greater White-fronted Geese
Craig R. Ely, David H. Ward, Karen S. Bollinger
1999, Condor (101) 390-395
We simultaneously monitored the heart rate and behavior of nine free-living Greater White-fronted Geese (Anser albifrons) on their wintering grounds in northern California. Heart rates of wild geese were monitored via abdominally-implanted radio transmitters with electrodes that received electrical impulses of the heart and emitted a radio signal with each...
Public acceptance of wildlife trapping in Colorado
M.J. Manfredo, C.L. Pierce, D. Fulton, J. Pate, B.R. Gill
1999, Wildlife Society Bulletin (27) 499-508
In November 1994, the Colorado Division of Wildlife (CDOW) initiated a stakeholder process to develop trapping regulations that would seek to achieve compromise among divergent interests. A telephone survey was conducted to provide stakeholders with information about the Colorado public's acceptance of trapping. A random sample of 900 residents, stratified...
High-pressure size exclusion chromatography analysis of dissolved organic matter isolated by tangential-flow ultra filtration
C.R. Everett, Y.-P. Chin, G. R. Aiken
1999, Limnology and Oceanography (44) 1316-1322
A 1,000-Dalton tangential-flow ultrafiltration (TFUF) membrane was used to isolate dissolved organic matter (DOM) from several freshwater environments. The TFUF unit used in this study was able to completely retain a polystyrene sulfonate 1,800-Dalton standard. Unaltered and TFUF-fractionated DOM molecular weights were assayed by high-pressure size exclusion chromatography (HPSEC). The...
The chemistry, mineralogy, and petrology of the George Ashley Block pegmatite body
W.D. Kleck, E.E. Foord
1999, American Mineralogist (84) 695-707
The George Ashley Block (GAB) is a rockslide block located in the Pala pegmatite district of Southern California. It is layered, asymmetric, pocket containing, and peraluminous. The GAB consists of quartz (42 vol%), Na-rich plagioclase (27%), potassium feldspar (24%), muscovite (7%), Mn-rich garnet (2%), biotite (1%), and a trace of...
Nesting habitat of least terns (Sterna antillarum athalassos) on an inland alkaline flat
Sara H. Schweitzer, David M. Leslie Jr.
1999, American Midland Naturalist (142) 173-180
We measured habitat characteristics in colony sites and at nest sites of endangered least terns (Sterna antillarum athalassos) on an expansive alkaline flat at Salt Plains National Wildlife Refuge, Oklahoma, in 1992 and 1993. Least terns nested in 12 colony sites on the alkaline flat during 1992 and 1993....
Incubation behavior of Spectacled Eiders on the Yukon-Kuskokwim Delta, Alaska
Paul L. Flint, J.B. Grand
1999, Condor (101) 413-416
We studied incubation behavior of Spectacled Eiders (Somateria fischeri) on the Yukon-Kuskokwim Delta in 1996. We trapped 19 females on their nests and weighed them in early incubation and again at hatch. Average daily weight loss for incubating females was 16.6 ± 1.0 g day-1, which resulted in a...
Effectiveness of an existing estuarine no-take fish sanctuary within the Kennedy Space Center, Florida
D.R. Johnson, N.A. Funicelli, James A. Bohnsack
1999, North American Journal of Fisheries Management (19) 436-453
Approximately 22% of the waters of the Merritt Island National Wildlife Refuge, which encompasses the Kennedy Space Center, Florida, have been closed to public access and fishing since 1962. These closed areas offer an opportunity to test the effectiveness of “no-take” sanctuaries by analyzing two replicated estuarine areas. Areas open...
Hydrocarbon gases associated with permafrost in the Mackenzie Delta, Northwest Territories, Canada
T. S. Collett, S.R. Dallimore
1999, Applied Geochemistry (14) 607-620
Molecular and isotopic analyses of core gas samples from 3 permafrost research core holes (92GSCTAGLU, 92GSCKUMAK, 92GSCUNIPKAT; sample core depths ranging from 0.36 to 413.82 m) in the Mackenzie Delta of the Northwest Territories of Canada reveal the presence of hydrocarbon gases from both microbial and thermogenic sources. Analyses of...
Results of repeated leveling surveys at Newberry Volcano, Oregon, and near Lassen Peak Volcano, California
D. Dzurisin
1999, Bulletin of Volcanology (61) 83-91
Personnel from the U.S. Geological Survey's Cascades Volcano Observatory conducted first-order, class-II leveling surveys near Lassen Peak, California, in 1991 and at Newberry Volcano, Oregon, in 1985, 1986, and 1994. Near Lassen Peak no significant vertical displacements had occurred along either of two traverses, 33 and 44 km long, since...
Hydrogen peroxide on the surface of Europa
R. W. Carlson, M.S. Anderson, R.E. Johnson, W. D. Smythe, A.R. Hendrix, C.A. Barth, L.A. Soderblom, G. B. Hansen, T. B. McCord, J.B. Dalton, R. N. Clark, J.H. Shirley, A.C. Ocampo, D. L. Matson
1999, Science (283) 2062-2064
Spatially resolved infrared and ultraviolet wavelength spectra of Europa's leading, anti-jovian quadrant observed from the Galileo spacecraft show absorption features resulting from hydrogen peroxide. Comparisons with laboratory measurements indicate surface hydrogen peroxide concentrations of about 0.13 percent, by number, relative to water ice. The inferred abundance is consistent with radiolytic...
Development of San Leandro synform and neotectonics of the San Francisco Bay block, California
M. S. Marlow, R.C. Jachens, P. E. Hart, P.R. Carlson, R. J. Anima, J.R. Childs
1999, Marine and Petroleum Geology (16) 431-442
High-resolution, 24-channel seismic-reflection data show a stratified synform beneath south San Francisco Bay. These seismic-reflection data reveal an eastward-dipping bedrock surface that is about 40 m deep (subbottom) beneath the western south bay, and that reaches a maximum observed depth of 500-800 m (subbottom) below the eastern half of the...
Explaining spatial variability in mean annual runoff in the conterminous United States
David M. Wolock, Gregory J. McCabe
1999, Climate Research (11) 149-159
The hydrologic concepts needed in a water-balance model to estimate the spatial variation in mean annual runoff for the 344 climate divisions in the conterminous United States (U.S.) were determined. The concepts that were evaluated were the climatic supply of water (precipitation), climatic demand for water (potential evapotranspiration), seasonality in...
The importance of SAR wavelength in penetrating blow sand in Northern Arizona
G. G. Schaber, C. S. Breed
1999, Remote Sensing of Environment (69) 87-104
Multifrequency and polarimetric Airborne Synthetic Aperture Radar (AIRSAR) images of a sand streak in northern Arizona demonstrate the ability of C- (6-cm wavelength), L- (24 cm), and P-band (68 cm) radar signals to backscatter, respectively, from increasingly greater depths reaching 2 m or more in active blow sand. The studied...
Strategies for ensuring global consistency/comparability of water-quality data
J.M. Klein
1999, Conference Paper, IAHS-AISH Publication
In the past 20 years the water quality of the United States has improved remarkably-the waters are safer for drinking, swimming, and fishing. However, despite many accomplishments, it is still difficult to answer such basic questions as: 'How clean is the water?' and 'How is it changing over time?' These...
Volcano-tectonic structures, gravity and helium in geothermal areas of Tuscany and Latium (Vulsini volcanic district), Italy
Filippo M. Di, S. Lombardi, G. Nappi, G.M. Reimer, A. Renzulli, B. Toro
1999, Geothermics (28) 377-393
Since the early 1980s, geological and structural mapping, gravity, and helium soil-gas studies have been performed in the eastern sector of the Vulsini Volcanic District (Roman Magmatic Province) in an attempt to locate potential geothermal reservoirs. This area is characterised by an anomalous geothermal gradient of > 100??C/km, and by...
