Jack Rawson
1979, Texas Department of Water Resources Report 230
The concentrations of dissolved solids, chloride, and sulfate in Livingston Reservoir on the Trinity River in southeastern Texas usually average less than 250 mg/l (milligrams per liter), 40 mg/l, and 50 mg/l, respectively. The water is usually hard or moderately hard (61 to 180 mg/l as calcium carbonate). The concentrations...

This report summarizes the data from near-in strong-motion accelerograph stations operated by the U.S. Geological Survey in the Imperial Valley of California at the time of the October 15, 1979 Imperial Valley earthquake. The purpose of this report is to alert others as to the nature of the strong-motion data...
Atlantic salmon embryos and fry: Effects of various incubation and rearing methods on hatchery survival and growth
Kenneth A. Leon, W.A. Bonney
1979, Progressive Fish-Culturist (41) 20-25
Significantly heavier fry of Atlantic salmon (Salmo salar) and greatly reduced mortality apparently resulted from the use of matrix substrates during egg incubation and alevin development. Salmon fry produced by this method fed readily and did not have the constricted yolk sacs that commonly occur when conventional rearing methods are used....

Environmental aspects of engineering geological mapping in the United States
Dorothy H. Radbruch-Hall
1979, Bulletin of the International Association of Engineering Geology (19) 351-358
Many engineering geological maps at different scales have been prepared for various engineering and environmental purposes in regions of diverse geological conditions in the United States. They include maps of individual geological hazards and maps showing the effect of land development on the environment. An approach to assessing the environmental...
Population ecology of house mice in unstable habitats
L.F. Stickel
1979, Journal of Animal Ecology (48) 871-887
(1) The relationships between habitat change and house mouse populations were studied by monthly live trapping in a corn-wheat-hay rotation on a small Maryland farm. (2) Population density reached 53.0/ha in a wheat/hay field in October and 25.4/ha in corn in September. Populations increased by immigration as wheat or corn...
The light-footed clapper rail: An update
Cynthia A. Wilburn, Paul D. Jorgensen, Barbara W. Massey, Venita A. Basham
1979, American Birds (33) 251-215
A preliminary report on the Light-footed Clapper Rail, Rallus longirostris levipes, estimated a population of 500-750 birds in California (Wilbur, Am. Birds 28:868-870, 1974). Since then, additional work has been accomplished, most notably: (1) an intensive study of Carpinteria Marsh, Santa Barbara County, 1976-1977 (Basham); (2) a series of winter...
Nationwide residues of organochlorine compounds in starlings (Sturnus vulgaris), 1976
Donald H. White
1979, Pesticides Monitoring Journal (12) 193-197
Organochlorine pesticide and PCB residues in starlings from 126 sites within the contiguous 48 states were monitored during fall 1976. The average nationwide level of DDE and PCBs has increased significantly since 1974, but the number of sites reporting PCB residues has decreased fivefold. Dieldrin residues have remained unchanged since...
Status of the everglade kite in Florida--1968-1978
P.W. Sykes Jr.
1979, The Wilson Bulletin (91) 495-511
The population status of the Everglade Kite (Rostrhamus sociabils plumbeus) was studied in Florida from 1968 through 1978. Sixty-four nestlings (40% of known fledged young) were leg-banded with unique color combinations, and of these, 17.2% were seen 1 or more years after they were banded. Kites were capable of breeding...
Nationwide residues of organochlorine compounds in wings of adult mallards and black ducks, 1976-77
Donald H. White
1979, Pesticides Monitoring Journal (13) 12-16
Organochlorine residues in wings of adult mallards and black ducks were monitored nationwide during the 1976-77 hunting season. DDE was found in all samples. Levels were unchanged since the 1972-73 collections in all migratory routes except the Pacific Flyway, in which residue levels declined significantly. Dieldrin levels had not changed...
Feeding ecology and development of juvenile black ducks in Maine
Kenneth J. Reinecke
1979, The Auk (96) 737-745
Data from 41 juvenile Black Ducks (Anas rubripes) collected in the Penobscot River valley of Maine from June through August 1974-76 were used to estimate the proportion of aquatic invertebrates in the prefledging diet and the allometric growth rates of the tarsi, flight muscles, and alimentary system. The proportion of...

Scent-marking in lone wolves and newly formed pairs
R.J. Rothman, L.D. Mech
1979, Animal Behaviour (27) 750-760
Scent-marking was studied in wolves (Canis lupus) along 133 km of tracks in northern Minnesota during winters of 1975 to 1976 and 1976 to 1977 and in two captive packs and four captive pairs for various periods. Lone wolves, which possess neither mates nor territories, rarely marked by raised-leg...
Organochlorine residues in young herons from the upper Mississippi River-1976
H. M. Ohlendorf, J. B. Elder, Rey C. Stendell, Gary L. Hensler, R.W. Johnson
1979, Pesticides Monitoring Journal (13) 115-119
Chicks of great blue herons (Ardea herodias) from four heronaries located near South St. Paul, Royalton, and Wabasha, Minnesota, and La Crosse, Wisconsin, were analyzed for organochlorines, Highest mean wet-weight concentrations, 6.43 ppm PCBs. 1.31 ppm DDE, and 1.90 ppm sigma DDT, were found in the South St. Paul chicks....
Agnonistic behavior in short-billed dowitchers feeding on a patchy resource
Elizabeth P. Mallory, Davod C. Schneider
1979, The Wilson Bulletin (91) 271-278
In this paper we describe an instance of unusual, agonistic behavior in a flock of migrant Short-billed Dowitchers (Limnodromus griseus) . We compare this behavior to that of other flocks feeding at the same time at other locations in the same estuary and then present evidence suggesting that this behavior...

Wolf howling and its role in territory maintenance
F.H. Harrington, L.D. Mech
1979, Behaviour (68) 207-249
An experimental study of the role of howling in wolf territory maintenance was conducted in the Superior National Forest, Minnesota. Vocal replies and behaviour of radio-collared wolves in response to human howls were analyzed for eight packs and 10 lone wolves during a 2-year period. Reply rate varied significantly throughout...
Annual weight cycle in wild screech owls
Charles J. Henny, Laurel F. VanCamp
1979, The Auk (96) 795-796
The annual weight cycle of wild birds of prey has received little attention in the past, primarily because of the difficulty in capturing and recapturing them. Screech Owls (Otus asio) are resident in our northern Ohio study area and readily occupy nest boxes established for Wood Ducks (Aix sponsa) (see...
Comparison of game-farm and wild-strain mallard ducks in accumulation of methylmercury
G. H. Heinz
1979, Journal of Environmental Pathology and Toxicology (3) 379-386
The accumulation of mercury was compared in game-farm and wild-strain mallard ducks fed a diet containing 0.5 ppm mercury in the form of methylmercury dicyandiamide. There were no significant differences between the two strains in levels of mercury that accumulated in blood, kidney, liver, breast muscle, brain, eggs, or ducklings....
