1982, Journal of Field Ornithology (53) 22-27
Sixteen hundred waterfowl, mostly Canada Geese, died near Etter, Texas, in late January 1981 from anticholinesterase poisoning. Winter wheat in the area of the die-off had been treated with organophosphate insecticides to control greenbugs. Cholinesterase (ChE) levels in brains of a sample of geese found dead were 75%...

Care of nestlings by wild female starlings exposed to an organophosphate pesticide
C.E. Grue, G.V.N. Powell, M.J. McChesney
1982, Journal of Applied Ecology (19) 327-335
(1) Our objective was to determine the effect of exposure to an organophosphate pesticide (OP), dicrotophos (3-hydroxy-N,N-dimethyl-cis-scrotonamide dimethyl phosphate), on care of nestlings by wild female starlings (Sturnus vulgaris).(2) We selected twelve pairs of active nests based on synchrony in the reproductive cycle. When nestlings were 10 days old (day...

Hormonal responses and tolerance to cold of female quail following parathion ingestion
Barnett A. Rattner, L. Sileo, C.G. Scanes
1982, Pesticide Biochemistry and Physiology (18) 132-138
Thirty-week-old female bobwhite quail (Colinus virginianus), maintained at 26 + 1?C, were provided diets containing 0,25, or 100 ppm parathion ad libitum. After 10 days, birds were exposed to mild cold (6 + 1?C) for 4,8, 12, 24, or 48 hr. Brain acetylcholinesterase activity was inhibited in a...
Influence of dietary protein and excess methionine on choline needs for young bobwhite quail
John A. Serafin
1982, Poultry Science (61) 902-908
Experiments were conducted with young Bobwhite quail (Colinus virginianus) to investigate the effect of differing dietary protein levels and nondetrimental amounts of excess methionine on choline needs. Growth and feed consumption of quail fed an adequate (27.3%) protein purified diet supplemented with 2000 mg/kg of choline were unaffected by increasing...

Influence of protein level and supplemental methionine in practical rations for young endangered masked bobwhite quail
John A. Serafin
1982, Poultry Science (61) 988-990
A study was conducted to examine the protein requirement of young endangered masked Bobwhite quail (Colinus virginianus ridgwayi). Five practical starting rations containing 24 to 32% protein were fed alone and supplemented with methionine for 5 weeks. Supplemental methionine significantly improved growth of quail fed diets containing 24...
Physical, Hydrological, and Biological Characteristics of the Loxahatchee River Estuary, Florida

1982, Water-Resources Investigations Report 82-350
The Loxahatchee River estuary empties into the Atlantic Ocean at Jupiter Inlet in southeastern Florida. Although relatively small, the estuary is important for its esthetic value and for its sport fishing, boating, recreation, tourism, and prime residential development. In recent years, the condition of the estuary has become of concern...
Wolf depredation on livestock in Minnesota
S. H. Fritts
1982, Resource Publication 145
Depredation by wolves (Canis lupus) on cattle, sheep, and other livestock in Minnesota currently is a minor problem except to a few individual farmers. Indices to the seriousness of the problem are available only from recent years, so historical trends cannot be detected. From 1976 through 1980 the number of...

Population ecology of the mallard: VII. Distribution and derivation of the harvest
Robert E. Munro, Charles F. Kimball
1982, Resource Publication 147
This is the seventh in a series of comprehensive reports on population ecology of the mallard (Anas platyrhynchos) in North America. Banding records for 1961-1975 were used, together with information from previous reports in this series, to estimate annual and average preseason age and sex structure of the mallard...

A workshop on raptor management and biology in Alaska and western Canada was held on February 20, 1981, in Anchorage, Alaska. It was attended by about 50 biologists. The following twofold prime objective was established: (1) To prevent any raptor species from becoming extirpated in any significant part of its...
