1974, Report
The U.S. Soil Conservation Service is actively engaged in the installation of flood- and soil-erosion reducing measures in Texas under the authority of "The Flood Control Act of 1936 and 1944" and "Watershed Protection and Flood Prevention Act" (Public Law 566), as amended. The Soil Conservation Service has found a...

Various fish species as biological control agents for the dark rice field mosquito in Arkansas rice fields
R. B. Davey, M. V. Meisch, D. L. Gray, J. M. Martin, Kermit E. Sneed, F. J. Williams
1974, Environmental Entomology (3) 823-826
During the summers of 1972–73, 10 fish species were evaluated as predators against larvae of the dark rice field mosquito, Psorophora confinnis (Lynch-Arribalzaga), near Stuttgart, Ark. Stocking rates were 0.02, 0.03, and 0.06 fish/ft 2 . At the lowest stocking rate green sunfish, Lepomis cyanellus Rafinesque, reduced larval numbers by 89.7% and were significantly more effective...

Gas-liquid chromatographic determination of 3-trifluoromethyl-4-nitrophenol residues in fish
J. L. Allen, J.B. Sills
1974, Journal of the Association of Official Analytical Chemists (57) 387-388
A procedure for the determination of 3-trifluormethyl-4-nitrophenol (TFM) in fish tissues is described. Homogenized tissues are extracted with hexane-ethyl ether; the extract is cleaned up by partitioning the TFM from the extracting solvent into 0.1N NaOH, acidifying the aqueous solution, and partitioning again with hexaneethyl ether. The TFM is methylated with...

The chemical composition and estimated minimum thermal reservoir temperatures of the principal hot springs of northern and central Nevada
Robert H. Mariner, J. B. Rapp, L.M. Willey, T. S. Presser
1974, Open-File Report 74-1066
Fifty-five of the principal hot springs in northern and central Nevada have been sampled for chemical analyses. Major element constituents, sodium, potassium, calcium, and silica suggest minimum thermal-aquifer temperatures of 140°C or more at 16 of the hot spring complexes. At least five of the hot springs issue mixed waters...
Nematode parasites of waterfowl (Anseriformes) from western United States
M.E. McDonald
1974, Wildlife Disease 19-19
Thirty-four species of nematodes were found in 415 Anseriformes (Anatidae) of 27 species; 93.7% of birds over 4 weeks old were infected. Data on prevalence, host specificity, age of host, and geographic distribution are given. Infections were more intense in sick birds and birds in poor physical condition. Accidental or...

An experimental trap net fishery, Lake Oahe, South Dakota, 1965
James A. Gabel
1974, Technical Paper 82
Large trap nets were evaluated as a commercial gear for capturing buffalo fish during July-September 1965. During the 72-day fishing period, 13,171 fish weighing 21,669 kg were taken. Bigmouth buffalo (Ictiobus cyprinellus) and smallmouth buffalo (Ictiobus bubalus) dominated the catch (78.2% by weight). Eight sport species accounted for 3.6% of...
Invertebrate macrobenthos of Lake Oahe, 1968-69
William E. Jones, James H. Selgeby
1974, Technical Paper 73
The benthos in Lake Oahe, as determined from about 450 bottom samples collected during the open water season in 1968 and 1969, was dominated by oligochaetes and chironomids; Caenis (Ephemeroptera) and Chaoborus (Diptera) were occasionally abundant. Total benthos was estimated at 3,600 organisms/mA? with an ash-free dry weight of about...

Urban water planning, development, and management are many sectored, costly efforts, subject to a multitude of controls and demands including those imposed by nature. One primary concern in development is for providing a dependable and safe water supply. In spite of a bountiful natural availability, the process of satisfying consumer...

Habitat management considerations for prairie chickens
L.M. Kirsch
1974, Wildlife Society Bulletin (2) 124-129
Lack of nesting and brood rearing habitat appears to be the universal limiting factor for prairie chickens (Tympanuchus cupido pinnatus) throughout their range. Grasslands are essential to prairie chickens, but vary widely in quality and thus in their ability to support prairie chickens. High-quality habitat is grassland providing residual vegetation...
Homing to nest baskets by wild female mallards

1974, Journal of Wildlife Management (38) 714-719
A high rate of homing to nest baskets by adult female mallards (Anas platyrhynchos) was observed in prairie potholes of North Dakota. One hundred and thirteen female mallards were caught on nest baskets, banded, and marked with nasal saddles. Forty-six percent homed at least once to nest baskets in the...
Myxosoma cerebralis: Comparative sensitivity of spore detection methods
M.E. Markiw, K. Wolf
1974, Journal of the Fisheries Research Board of Canada (31) 1597-1600
Physical and biophysical methods of detecting spores of Myxosoma cerebralis were used in sequence on 87 individual fingerling rainbow trout (Salmo gairdneri) from two populations with a low incidence of infection. Physical methods of releasing spores from the organs of equilibrium, gill arches, or the axial skeleton gave an estimated rate of...
