Aroclor 1242 and reproductive success of adult mallards (Anas platyrhynchos) Aroclor 1242 and reproductive success of adult mallards (Anas platyrhynchos)
Twenty-four pairs of adult mallards were fed a diet containing 0 or 150 ppm of the PCB Aroclor 1242 for 12 weeks during which egg laying was induced. Laying started in both groups an average of 33 days after PCB treatment began. All hens were allowed to lay a 20-egg clutch; 15 eggs from each clutch were artificially incubated. Eleven hens from each group completed the clutch. There was...

Canine tooth wear in captive little brown bats Canine tooth wear in captive little brown bats
Upper canine teeth of little brown bats Myotis lucifugus lucifugus held in stainless steel wire mesh cages underwent severe wear which exceeded that observed previously in caged big brown bats, Eptesicus fuscus fuscus. This suggests a relationship between amount of wear and size of the caged bats with damage increasing as size decreases. Rapid wear of canine teeth by little brown bats...

Wildlife hazards from Furadan 3G applications to rice in Texas Wildlife hazards from Furadan 3G applications to rice in Texas
Mortality of birds, fish, frogs, crayfish, earthworms, and nontarget insects occurred in rice fields after treatments of Furadan 3G granules in 3 Texas counties in 1970 and 1973-75. Three western sandpipers (Ereunetes mauri), 1 pectoral sandpiper (Erolia melanotos), and 2 red-winged blackbirds (Agelaius phoeniceus) were found dead or moribund between 17 and 24 hours after treatment...

Residues of environmental pollutants and necropsy data for eastern United States ospreys, 1964-1973 Residues of environmental pollutants and necropsy data for eastern United States ospreys, 1964-1973
Thirty-three ospreys (Pandion haliaetus) that were found dead or moribund in the Eastern United States between 1964 and 1973 were necropsied. The brains and carcasses of 26 of these birds were analyzed for organochlorines. The livers of 18 and the kidneys of 7 were analyzed for selected metals. Most adults were recovered in April and May and most immatures were recovered in August...

Serologic and hematologic values of wild coyotes in Wisconsin Serologic and hematologic values of wild coyotes in Wisconsin
Blood samples were obtained from 30 coyotes (Canis latrans) captured in northern Wisconsin in conjunction with radio-telemetry studies. Samples were assayed for seven hematologic values, seven serum chemistries, serum albumin, globulin and total protein. Results are given with respect to sex and age and are compared with available data for captive wild and pen-raised coyotes. Leukocyte...

Effects of petroleum hydrocarbons on hepatic function in the duck Effects of petroleum hydrocarbons on hepatic function in the duck
1. The indocyanine green dye clearance test for hepatic function was determined in mallard ducks before and during the chronic ingestion (7 months) of representative paraffinic or aromatic petroleum hydrocarbons (PH). 2. No mortality or visible symptoms of toxicity occurred in any of the tests. Ingestion of 4000 ppm aromatic PH produced significant increases in liver (25%), plasma...
