Reproduction and residue accumulation in black ducks fed toxaphene Reproduction and residue accumulation in black ducks fed toxaphene
Three sets of 15 pairs of black ducks (Anas rubripes) were given 0, 10, or 50 ppm toxaphene in a dry mash diet for a period of 19 months, which included two breeding seasons. Survival of adults was not affected, but the weights of treated males were depressed during the summer months. Egg production, fertility, hatchability, eggshell thickness, growth, and survival of young did not vary...

Toxic effects of endrin and toxaphene on the southern leopard frog Rana sphenocephala Toxic effects of endrin and toxaphene on the southern leopard frog Rana sphenocephala
Eggs, larvae and sub-adults of the southern leopard frog Rana sphenocephala were exposed to endrin and toxaphene. Exposure was in water by a continuous-flow technique, following standards that have been used successfully in the study of fish and invertebrates. R. sphenocephala is more sensitive to both pesticides than are higher vertebrates but is slightly less sensitive than fish. Eggs...

Organochlorine residues were analyzed in blubber, brain, or muscle tissues of 69 individuals representing 10 species of small cetaceans. Collections were made from November 1968 through June 1976 at localities in the Eastern Tropical Pacific and along the coasts of California, Hawaii, Japan, and Uruguay, Relations of residue concentrations between tissues are described for DDE and PCBs...

Coastal and Marine Bird Data Base Coastal and Marine Bird Data Base
Summary: This report discusses the development of a coastal and marine bird data base at the Migratory Bird and Habitat Research Laboratory. The system is compared with other data bases, and suggestions for future development, such as possible adaptations for other taxonomic groups, are included. The data base is based on the Statistical Analysis System but includes extensions programmed

Prairie dog distribution in areas inhabited by black-footed ferrets Prairie dog distribution in areas inhabited by black-footed ferrets
The distribution of black-tailed prairie dog (Cynomys ludovicianus) towns was delineated in a 1490 km2 study area in Mellette County, South Dakota, and was examined to determine the characteristics of black-looted ferret (Mustela nigripes) habitat. Between 1964 and 1974, black-looted ferrets were observed on 14 prairie dog towns in this area. Eighty-six prairie dog towns, located...
