Some aspects of breeding biology of the blue-winged teal
C.W. Dane
1966, The Auk (83) 389-402
The Blue-winged Teal (Anas discors) was the subject of one of the first publications dealing with the breeding biology of a species of North American waterfowl (Bennett, 1938). Recent studies of the nesting chronology, clutch size, and incubation period of this species include the works of Hochbaum (1944), Sowls (1955),...

Preparation of dart tags for use in the field
Joseph R. Higham
1966, Progressive Fish-Culturist (28) 205
Tagging in the field requires an efficient method of preparing the tags for dispensation under a wide range of conditions. The method described here was very efficient in an extensive tagging program on Oahe Reservoir, South Dakota....
Uptake of 2,4-dichlorophenoxyacetic acid by Pseudomonas fluorescens
Gary Wedemeyer
1966, Applied and Environmental Microbiology (14) 486-491
Factors influencing the uptake of the sodium salt of 2,4-dichlorophenoxyacetic acid (2,4-D), under conditions in which no net metabolism occurred, were investigated in an effort to determine both the significance of “non-metabolic” uptake as a potential agent in reducing pesticide levels and the mechanisms involved. Uptake of 2,4-D was affected...
Toxicities of several pesticides to two species of Cladocerans
Herman O. Sanders, Oliver B. Cope
1966, Transactions of the American Fisheries Society (95) 165-169
Laboratory bioassays were conducted with some chlorinated hydrocarbon insecticides, organophosphate insecticides, other insecticides and acaricides, and with herbicides to determine their relative toxicities and immobilization values for two species of daphnids, Daphnia pulex and Simocephalus serrulatus. Both species are satisfactory bioassay organisms for the determination of a wide variety...
Persistence of 2,6-Dichlorobenzonitrile in aquatic environments
C.C. Van Valin
1966, Book chapter, Organic pesticides in the environment
In two experiments 2,6-dichlorobenzonitrile was added to aquatic systems, and the residue levels were followed for about 6 months. A granular formulation applied to a farm pond at 0.6 p.p.m. produced highest residues in water and fish about 2 weeks following treatment whereas vegetation and soil samples had the highest...
Waste injection into a deep limestone in northwestern Florida
J.T. Barraclough
1966, Groundwater (4) 22-24
During a three-month trial period, 70 million gallons of industrial wastes were successfully injected at moderate pressures into a deep limestone in the westernmost part of Florida. The movement of these wastes is expected to be predominantly southward toward the natural discharge area which is presumed to be far out...
