Isolation of Mycobacterium avium from waterfowl with polycystic livers
Thomas J. Roffe
1989, Avian Diseases (33) 195-198
An unusual gross appearance of avian tuberculosis, where fluid-filled thin-walled cysts are produced and grossly apparent in preference to granulomas, is presented. Histopathology confirmed the granulomatous nature of the lesions and the presence of intracellular acid-fast organisms. Mycobacterium avium complex was cultured from affected organs. The unusual gross presentation in...
Hydrological, morphometrical, and biological characteristics of the connecting rivers of the International Great Lakes: a review
Clayton J. Edwards, Patrick L. Hudson, Walter G. Duffy, Stephen J. Nepszy, Clarence D. McNabb, Robert C. Haas, Charles R. Liston, Bruce Manny, Wolf-Dieter N. Busch
D.P. Dodge, editor(s)
1989, Book, Proceedings of the International Large River Symposium
The connecting channels of the Great Lakes are large rivers (1, 200-9, 900 m3 • s-1) with limited tributary drainage systems and relatively stable hydrology (about 2:1 ration of maximum to minimum flow). The rivers, from headwaters to outlet, are the St. Marys, St. Clair, Detroit, Niagara, and St. Lawrence....
Suggestions for prospecting
Water Resources Division, U.S. Geological Survey
1989, Report
Prospectors have contributed much to the development of this Nation's mineral resources. Since the time of the earliest settlement, the need for iron for tools and guns, lead for bullets, and copper for utensils has prompted a search for sources of these metals. The lure of gold and silver provided...
Transport and degradation of water-soluble creosote-derived compounds
E. Michael Godsy, D.F. Goerlitz, Dunja Grbic-Galic
D. Allen, editor(s)
1989, Book chapter, Intermedia pollutant transport: Modeling and field measurements
Creosote is the most extensively used insecticide and industrial wood preservative today. It is estimated that there are more than 600 wood-preserving plants in the United States, and their collective use of creosote exceeds 4.5xl06 kg/yr (von Rumker et al., 1975). Creosote is a complex mixture of more than...

L.M. Smith, R.L. Pederson, R.M. Kaminski, editor(s)
1989, Book chapter, Habitat management for migrating and wintering waterfowl in North America
Pesticide contamination of rice prairie waterfowl habitat and acute pesticide poisoning of wintering and migrating waterfowl on the rice prairies has been reduced in recent years. Some problems still exist....
Gazetteer of the Antarctic
U.S. Board on Geographic Names, Defense Mapping Agency, Water Resources Division, U.S. Geological Survey, National Science Foundation
1989, Report 89-98
This gazetteer lists antarctic names approved by the United States Board on Geographic Names and by the Secretary of the Interior. The Board is the interagency body created by law to standardize and promulgate geographic names for official purposes. As the official standard for names in Antarctica, the gazetteer assures...
Premigrational movements and behavior of young mallards and wood ducks in north-central Minnesota
R.E. Kirby, L.M. Cowardin, J.R. Tester
1989, Fish and Wildlife Research 5
Movements and behavior of 89 young mallards (Anas platyrhynchos) and 48 young wood ducks (Aix sponsa) were monitored on a 932-km2 study area in north-central Minnesota in late summer and fall, 1972-74, with telemetry, visual observation, and aerial surveys. Initial flights of both species were confined to the natal (brood)...
Field test of a bioassay procedure for assessing habitat quality on fish spawning grounds
Bruce A. Manny, David J. Jude, Randy L. Eshenroder
1989, Transactions of the American Fisheries Society (118) 175-182
A bioassay procedure to assess habitat quality was tested on Port Austin reef in southern Lake Huron, a spawning area of lake trout Salvelinus namaycush. In 1986, Plexiglas incubators filled with fertilized lake trout eggs were buried by scuba divers in rock rubble at two sites. The incubators then were attached...
Microcontaminants and reproductive impairment of the Forster's tern on Green Bay, Lake Michigan,1983
T.J. Kubiak, H.J. Harris, L.M. Smith, T.R. Schwartz, D.L. Stalling, J.A. Trick, L. Sileo, D. E. Docherty, T.C. Erdman
1989, Archives of Environmental Contamination and Toxicology (18) 706-727
For the 1983 nesting season, Forster's tern (Sterna forsteri) reproductive success was significantly impaired on organochlorine contaminated Green Bay, Lake Michigan compared to a relatively uncontaminated inland location at Lake Poygan, Wisconsin. Compared with tern eggs from Lake Poygan, eggs from Green Bay had significantly higher median concentrations...
An empirical Bayes approach to analyzing recurring animal surveys
Douglas H. Johnson
1989, Ecology (70) 945-952
Recurring estimates of the size of animal populations are often required by biologists of wildlife managers. Because of cost or other constraints, estimates frequently lack the accuracy desired but cannot readily be improved by additional sampling. This report proposes a statistical method employing empirical Bayes (EB) estimators as alternatives to...
Estimating carcass fat and protein in northern pintails during the nonbreeding season
Michael R. Miller
1989, Journal of Wildlife Management (53) 123-129
I used northern pintails (Anas acuta) collected from August through March 1979-82 in the Sacramento Valley, California to derive equations to predict ether-extracted carcass fat, carcass protein, and skeletal lean dry weight. Ether-extracted carcass fat was best predicted by total fat depot weight (wet skin, abdominal fat, and intestinal fat)...
A comparison of aquatic macrophyte communities in regulated and non-regulated lakes, Voyageurs National Park and Boundary Waters Canoe Area, Minnesota
James E. Meeker, Douglas A. Wilcox
1989, Research/Resources Management MWR-16
The effects of water-level regulation on aquatic macrophyte communities, individual plant species, and potential faunal habitat were investigated in a study of two regulated lakes and an unregulated lake in northern Minnesota. Water levels in Rainy Lake and Namakan Reservoir in Voyageurs National Park are regulated by dams. Natural annual...
Gas phase axial dispersion in a packed column oxygen absorber
Barnaby J. Watten, Claude E. Boyd
1989, Aquacultural Engineering (8) 421-434
Gas phase axial dispersion was characterized within an enclosed packed column receiving oxygen and water under counter-current flow conditions. Steady-state gas phase profiles (longitudinal) were measured during a series of 90 column runs in which, at each of three bed depths (0·362, 0·699, and 1·041 m), all combinations of the...
Distribution, habitat, and future of Harter's water snake, Nerodia harteri, in Texas
N.J. Scott Jr., T.C. Maxwell, O.W. Thornton Jr., L.A. Fitzgerald, J.W. Flury
1989, Journal of Herpetology (23) 373-389
Detailed studies of the distribution and habitat use of the endemic Texas snake Nerodia harteri were conducted from 1979 to 1987. The Brazos water snake N. h. harteri is restricted to the upper Brazos River drainage; it is found in about 303 km of stream plus two reservoirs, Possum Kingdom...
