Digital image processing system For Landsat 3
George Harris Jr.
1979, Conference Paper, Proceedings volume 0183, Space Optics II
The Department of Interior (DOI) and the National Aeronautics and Space Administration (NASA) have entered into a joint program to provide a digital image processing system in support of the Landsat 3 mission. NASA will provide the data reception and pre-processing facilities, while the DOI provides the production image processing...
Effects of aldrin exposure on snow geese in Texas rice fields
Edward L. Flickinger
1979, Journal of Wildlife Management (43) 94-101
In 1972 and 1974, 112 dead or moribund snow geese (Chen c. caerulescens), mostly immature white-phase males, were found in a study area on the Garwood Prairie, Texas. Dying geese were observed within 2 days after rice fields planted with aldrin-treated seed were flooded by heavy tains6n 21 March 1972...
Primary feather molt of adult mourning doves in North and South Carolina
G.H. Haas, S.R. Amend
1979, Journal of Wildlife Management (43) 202-207
Examination of 8,141 adult mourning doves (Zenaida macroura) in North and South Carolina revealed that substantial numbers complete primary feather molt in September. Adult mourning doves shed primaries at the rate of 1 per 14 days. No difference was found in this rate between sexes or among years, 1969-74. The...
Contributions to the mammalogy of Chile
Ronald H. Pine, Sterling D. Miller, Mel L. Schamberger
1979, Mammalia (43) 339-376
Collections of mammals were made during more than three years of biological investigations in Chile sponsored by the Corporación Nacional Forestal under the aegis of the Peace Corps (Smithsonian Environmental Program). Genera and species hitherto unreported for that country were taken and many useful data concerning distributional patterns of...
An improved method of censusing deer in deciduous-coniferous forests
T.J. Floyd, L.D. Mech, M.E. Nelson
1979, The Journal of Wildlife Management (43) 258-261
Aerial censusing has been used to determine densities of many large mammals, including deer (Odocoileus virginianus) in agricultural areas or deciduous forests (Saugstad 1942, Morse 1946, Petrides 1953, Sanderson 1953, Berner pers. comm.). However, observability of deer from the air remains a problem in northern coniferous forests. LeResche and...

Line transect estimation of population size: the exponential case with grouped data
David R. Anderson, K.P. Burnham, B.R. Crain
1979, Communications in Statistics - Theory and Methods (8) 487-507
Gates, Marshall, and Olson (1968) investigated the line transect method of estimating grouse population densities in the case where sighting probabilities are exponential. This work is followed by a simulation study in Gates (1969). A general overview of line transect analysis is presented by Burnham and Anderson (1976). These articles...
Excretion of the lampricide Bayer 73 by rainbow trout
J. L. Allen, V. K. Dawson, J. B. Hunn
L. L. Marking, R. A. Kimerle, editor(s)
1979, Conference Paper, Aquatic toxicology: Proceedings of the second annual symposium on aquatic toxicology
Urinary excretion of the 2-aminoethanol salt of 2′, 5-dichloro-4′-nitrosalicylanilide (Bayer 73) in rainbow trout (Salmo gairdneri) was measured after exposure of the trout to Bayer 73 and also after intraperitoneal (ip) injection of the lampricide. Fish exposed to 0.05 mg/litre of Bayer 73 for 12 h quickly began to excrete...
