A rapid field techniques for preparing ant chromosomes for karyotypic analysis A rapid field techniques for preparing ant chromosomes for karyotypic analysis
This technique for chromosomal preparation of ant tissues for karyotypic analysis is advantageous under field conditions because it reduces processing time and can be used under humid conditions. The cerebral ganglia from prepupae or early pupae are incubated 20 minutes in a hypotonic citrate solution, minced in a fixative solution of 3:3:4 glacial acetic acid: absolute methanol...

Short-term effects of oil ingestion on American kestrels (Falco sparverius) Short-term effects of oil ingestion on American kestrels (Falco sparverius)
The Mexican Ixtoc oil well blowout resulted in extensive oil contamination along the Texas Gulf coast. This oil posed a potential hazard to migrating birds including the endangered peregrine falcon (Falco peregrinus). Laboratory tests with the American kestrel (Falco sparverius) indicated that the oil: water mixture gathered at the surface of the blowout site posed little acute hazard to...

Anarbylus switaki Murphy: An addition to the herpetofauna of the United States with comments on relationships with Coleonyx Anarbylus switaki Murphy: An addition to the herpetofauna of the United States with comments on relationships with Coleonyx
Anarbys switaki, a species previously known only from Baja California Sur, Mexico, occurs in eastern San Diego and southwestern Imperial Counties in California. In California, specimens tend to have continuous transverse bars on the body, are lighter in color, and more slender in body form than in southern Baja California. California populations appear to be confined to extremely rocky...

DDE not implicated in cliff swallow, Petrochelidon pyrrhonota, mortality during severe spring weather in Oregon DDE not implicated in cliff swallow, Petrochelidon pyrrhonota, mortality during severe spring weather in Oregon
Large numbers ofCliff Swallows (Petrochelidon pyrrhonota) died in late May near Burns, Oregon, during cold, wet weather. The brains of five dead birds did not contain lethal concentrations of DDE, and no PCBs were detected.

Migratory peregrine falcons, Falco peregrinus, accumulate pesticides in Latin America during winter Migratory peregrine falcons, Falco peregrinus, accumulate pesticides in Latin America during winter
Blood samples from 433 Peregrine Falcons (Falco peregrinus) during fall and spring migrations, 1976-80, indicated that most of their pesticide burden, primarily DDE, was accumulated on wintering grounds in Latin America. DDE in spring migrants returning from Latin America for the first time declined significantly from 1979 to 1980. Only about 10% of breeding-age females contained...

Organophosphate inhibition of avian salt gland Na, K-ATPase activity Organophosphate inhibition of avian salt gland Na, K-ATPase activity
1. Adult black ducks (Anas rubripes) were given freshwater or saltwater (1.5% NaCl) for 11 days and half of each group was also given an organophosphate (17 p.p.m. fenthion) in the diet on days 6–11. 2. After 11 days, ducks drinking saltrwater had lost more weight and had higher plasma Na and uric acid concentration and osmolalities than birds drinking freshwater. 3. Saltwater treatment...
