Daily water-temperature records for Utah streams, 1944-68
G.L. Whitaker
1970, Utah Basic-Data Release 19
Temperature is an important and sometimes critical factor for many uses of water. Temperature affects the usefulness of the water for recreation, fish and wildlife propagation, industrial cooling, food processing, and manufacturing. Temperature also affects the ability of the water to accommodate biologic and vegetative types of life.The purpose of...

Leif L. Marking, Everett L. King, Charles R. Walker, John H. Howell
1970, Investigations in Fish Control 38
The chemical 33NCS (3'-chloro-3-nitrosalicylanilide) was evaluated as a fish control agent and as a larvicide for sea lampreys at the Fish Control Laboratories of the Bureau of Sport Fisheries and Wildlife and the Hammond Bay Biological Station of the Bureau of Commercial Fisheries. The chemical is rapidly toxic to many...

Lithium metaborate flux in silicate analysis
C.O. Ingamells
1970, Analytica Chimica Acta (52) 323-334
Lithium metaborate is an effective flux for silicates and other rock-forming minerals. The glass resulting from fusion is mechanically strong, reasonably nonhygroscopic, and is readily soluble in dilute acids. These characteristics lead to its use in X-ray spectrography and in methods which require whole-rock solutions,...

Valle R. Gomez, J. D. Friedman, S.J. Gawarecki, C.J. Banwell
1970, Geothermics (2)
New techniques, involving interpretation of panchromatic, ektachrome and ektachrome infrared aerographic photogaphs and thermographic infrared imagery recording emission from the earth's surface in middle and far infrared wavelengths (3–5μm and 8–14μm), are being introduced in geothermal investigations in Mexico to identify outstanding structural and geologic features in a rapid and...
Let's Sing 'Auld Lang Syne' for the Upper Brandywine: Or, to continue with Burns, how the best laid environmental schemes of men "gang aft a-gley"
Luna Bergere Leopold
1970, Natural History (79) 5-15
Perhaps the most lamentable mistake that one can make is to be right too soon. This was the story of the Brandywine Plan, an attempt to organize local people for the permanent protection of the environmental amenities of their own land.The Upper East Branch of Brandywine Creek drains a rolling...

Waterfowl breeding habitat in agricultural and nonagricultural land in Manitoba
T.J. Dwyer
1970, Journal of Wildlife Management (34) 130-136
Waterfowl populations and habitat characteristics were examined on 33 potholes in each of two 16-square-mile study areas of agricultural and nonagricultural land in southwestern Manitoba. The agricultural land potholes, lacking in or incompletely surrounded by trees, received greater use by lesser scaup (Aythya affinis), canvasback (A. valisineria), redhead (A. americana),...
Waterfowl in relation to land use and water levels on the Spring Run Area
Gary L. Krapu, D.R. Parsons, M.W. Weller
1970, Iowa State Journal of Science (44) 437-452
Low water levels during critical phases of the breeding cycle appear to have caused population declines of waterfowl and other marsh birds on the Spring Run Game Management Area. Pair-counts indicated a decline from 70 pairs of waterfowl in 1965 to 2 pairs in 1968. Nest success of upland nesting...

Accumulation of radionuclides in bed sediments of the Columbia River between Hanford reactors and McNary Dam
Jack L. Nelson, W.L. Haushild
1970, Water Resources Research (6) 130-137
Amounts of radionuclides from the Hanford reactors contained in bed sediments of the Columbia River were estimated by two methods: (1) from data on radionuclide concentration for the bed sediments between the reactors and McNary Dam, and (2) from data on radionuclide discharge for river stations at Pasco, Washington, and...

Studies on the life history and development of Cuterebra polita (Diptera: Cuterebridae) in four species of rodents
K.J. Capelle
1970, Journal of Medical Entomology (7) 320-327
Cuterebra polita Coquillett is a primary parasite of the pocket gopher. Thomomys talpoides. in the western United States. It also occurs secondarily in other wild rodents that come into close contact with pocket gophers.Field studies disclosed pursuit, mating, and ovipositing at an aggregation site near Monte Cristo, Utah. Eggs were...
Correction of bias in belt transect studies of immotile objects
David R. Anderson, R.S. Pospahala
1970, Journal of Wildlife Management (34) 141-146
Unless a correction is made, population estimates derived from a sample of belt transects will be biased if a fraction of, the individuals on the sample transects are not counted. An approach, useful for correcting this bias when sampling immotile populations using transects of a fixed width, is presented....
Effects of alewife predation on zooplankton populations in Lake Michigan
LaRue Wells
1970, Limnology and Oceanography (15) 556-565
The zooplankton populations in southeastern Lake Michigan underwent striking, size-related changes between 1954 and 1966. Forms that decline sharply were the largest cladocerans (Leptodora kindtii, Daphnia galeata, and D. retrocurva), the largest calanoid copepods (Limnocalanus macrurus, Epischura lacustris, and Diaptomus sicilis), and the largest cyclopoid copepod (Mesocyclops edax). Two of...
Retention of mercury by salmon
Donald F. Amend
1970, Progressive Fish-Culturist (32) 192-194
Consuming fish that have been exposed repeatedly to mercury derivatives is a potential public health hazard because fish can accumulate and retain mercury in their tissues (Rucker, 1968). Concern has been expressed in the United States because mercurials have been used extensively in industry and as prophylactic and...
Thermal features at Volcanoes in the cascade range, as observed by aerial infrared surveys
R.M. Moxham
1970, Bulletin Volcanologique (34) 77-106
There have been no substantial changes in the thermal patterns at the summit of Mount Rainier in the period September 1964–September 1966, within the detection limits of the infrared instrumentation. Some differences in radiance are attributed to differences in snow cover. The highest apparent temperature is at a snow-free area...

Edward H. Brown Jr.
C.C. Lindsey, C.S. Woods, editor(s)
1970, Book chapter, Biology of coregonid fishes
The sex composition and other biological characteristics of the bloater changed substantially during recent decades of continuous ecological change in Lake Michigan. The percentages of females increased from 72% of the bloaters samples in 1928-32 to 95% in 1963, and ranged from 94 to 97% in 1964-69. The unusual predominance...

D.R. Cline
1970, Report
The response of game-farm mallards (Frost strain) to seven pharmacological immobilizing agents was evaluated in Phase I of a planned four-phase study. A limited amount of testing was also done with wild mallards. Single dosages were administered to determine the mean effective dose (ED50) and mean lethal dose (LD50), The...
