Changes in vegetation structure in seeded nesting cover in the prairie pothole region
K.F. Higgins, W.T. Barker
1982, Special Scientific Report - Wildlife 242
A sample of 365 stands of seeded nesting cover (mixtures of cool-season grasses and legumes) was studied in the glaciated prairie pothole region during 1977-79. Measurements of species composition, canopy cover, plant height, and visual obstruction values differed with stand age but only in a general way when results from...

Accumulation and loss of 2' ,5-dichloro-4'-nitrosalicylanilide (Bayer 73) by fish: laboratory studies
Verdel K. Dawson, Joe B. Sills, Charles W. Luhning
1982, Investigations in Fish Control 90
Residues of the 2-aminoethanol salt of 2',5-dichloro-4'-nitrosalicylanilide (Bayer 73), as determined by gas-liquid chromatography, were rapidly accumulated by fish exposed to the lampricide -in blood plasma, gallbladder bile, and muscle tissue of coho salmon (Oncorhynchus kisutch) and rainbow trout (Salmo gairdneri), and in bile and muscle of channel catfish (Ictalurus...

Breeding-ground habitat conditions and the survival of mallards
James D. Nichols, Richard S. Pospahala, James E. Hines
1982, Journal of Wildlife Management (46) 80-87
The relationship between habitat conditions in prairie breeding areas of North America and mallard (Anas platyrhynchos) survival rates was investigated. Annual survival-rate estimates for mallards generally were higher during years of high May pond numbers and low mallards-per-pond ratios than during years of low pond numbers and high ratios. This...

On the availability of geoscientific data and scientific collaborators of an in Africa
David A. Hastings
1982, Geoexploration (20) 201-205
In addition to the technical papers, the major topic of discussion at the symposium which formed the stepping-off point for this issue of Geoexplorution was the difficult communications between specialists on Africa and the lack of available geological and geophysical data. However, much of this difficulty stems from a lack...
Changes in vegetation and grazing capacity following honey mesquite control
Kirk C. McDaniel, John H. Brock, Robert H. Haas
1982, Journal of Range Management (35) 551-557
Honey mesquite kill and suppression, vegetation response, and changes in grazing use and capacity were evaluated following brush control in north-central Texas. Tree grubbing was most effective for eliminating honey mesquite, but because of soil and plant damage the treatment did not increase grazing capacity or improve range condition compared...
Case report: lead poisoning in common loons (Gavia immer)
Louis N. Locke, Stephen M. Kerr, D. Zoromski
1982, Avian Diseases (26) 392-396
Two emaciated common loons (Gavia immer) were believed to have died of lead poisoning when fragments of fishing lines and lead sinkers were discovered in their stomachs. Later a third emaciated loon, which had only the remnants of fishing line in its stomach, was suspected of being a possible lead-poisoning...
Characterization of tropospheric desert aerosols at solar wavelengths by multispectral radiometry from Landsat
Joseph Otterman, R. S. Fraser, O. P. Bahethi
1982, Journal of Geophysical Research C: Oceans (87) 1270-1278
Characteristics of tropospheric desert aerosols are derived by comparing nadir spectral reflectivities computed from the radiative transfer models with reflectivities measured from Landsat. Over the ocean, reflectivities are compared, but over land the comparison is carried out by determining the ratios of the nadir reflectivity of the surface-atmosphere system over...
Preliminary correlations of MAGSAT anomalies with tectonic features of Africa
David A. Hastings
1982, Geophysical Research Letters (9) 303-306
An overview of the MAGSAT scalar anomaly map for Africa has suggested a correlation of MAGSAT anomalies with major crustal blocks of uplift or depression and different degrees of regional metamorphism. The strongest MAGSAT anomalies in Africa are closely correlated spatially with major tectonic features. Although a magnetic anomaly caused...
Evaluation of the river die-away biodegradation test
Glenn D. Wylie, John R. Jones, B. Thomas Johnson
1982, Journal of the Water Pollution Control Federation (54) 1231-1236
The reliability of the river die-away (RDA) test for establishing the biodegradability of chemicals was assessed. Reproducibility of biodegradation in the RDA test was analyzed under conditions in which the test is commonly done. Biodegradation results were not reproducible for di-2-ethylexyl phthalate (DEHP) and phthalic acid in replicated RDA tests...

The nomenclatural enigma of single versus double -i endings for scientific patronyms emended to represent a man's name: A comment and some considerations
M.R. Jennings
1982, Fisheries (7) 9-10
The current inconsistency over the use of single vs. double -i endings for singular masculine scientific patronyms in official lists of scientific names of fishes causes needless confusion and labor. Taxonomists once preferred rules for Latinization calling for double -i endings, but current rules suggest single -i endings. Recent rulings by the International Commission of Zoological...
An assessment of Landsat data acquisition history on identification and area estimation of corn and soybeans
M. M. Hixson, M. E. Bauer, Donna K. Scholz
1982, Remote Sensing of Environment (12) 123-128
In the past decade, numerous studies have demonstrated the potential of satellite remote sensing for providing accurate timely crop area information. This study assessed the impact of Landsat data acquisition history on classification and area estimation accuracy of corn and soybeans in the U.S. Corn Belt. The results illustrate the...
On the tectonics and metallogenesis of West Africa: a model incorporating new geophysical data
David A. Hastings
1982, Geoexploration (20) 295-327
The gold, diamond and manganese deposits of Ghana have attracted commercial interest, but appropriate geophysical data to delineate the tectonic setting of these and other deposits have been lacking until recently. Recent gravity surveys, however, now cover about 75% of the country. When used in a synthesis of the sometimes...

1982, Photogrammetric Engineering and Remote Sensing (48) 139-141
A working conference was held in Sioux Falls, South Dakota, 12-14 November, 1980 dealing with Landsat classification Accuracy Assessment Procedures. Thirteen formal presentations were made on three general topics: (1) sampling procedures, (2) statistical analysis techniques, and (3) examples of projects which included accuracy assessment and the associated costs, logistical...
