Lead exposure alters the development of agonistic behavior in golden hamsters.
We tested the effects of exposure to different doses of lead acetate (either 0, 25, 100, or 400 ppm) on the development of aggressive behavior in male golden hamsters. Pups were tested for offensive responses across puberty, as they were maturing from play fighting to adult aggression. Our data show a dose-specific effect of lead exposure on the development of aggression during puberty at doses...
متن کاملExposure to lead during development alters aggressive behavior in golden hamsters.
The present studies were designed to test the effects of early exposure to low doses of lead on aggressive behavior in male golden hamsters. Litters of hamsters were exposed to lead acetate (either 0 or 100 ppm) from embryonic day 8, through weaning on postnatal day 25 (P-25), until P-42. Play fighting behavior was tested on P-19 and P-20 around the developmental onset of the behavior. During t...
متن کاملImpact of the California Lead Ammunition Ban on Reducing Lead Exposure in Golden Eagles and Turkey Vultures
Predatory and scavenging birds may be exposed to high levels of lead when they ingest shot or bullet fragments embedded in the tissues of animals injured or killed with lead ammunition. Lead poisoning was a contributing factor in the decline of the endangered California condor population in the 1980s, and remains one of the primary factors threatening species recovery. In response to this threa...
متن کاملSheep Depredation by Golden Eagles in Montana
A limited study on two ranches near Dillon, Montana, near the end of the lambing season in 1974 revealed that 44 domestic lambs were killed by golden eagles (Aquila chrysaetos). This was 76 percent of all deaths recorded during the short study. Using an average docking percent of 90 (based on years before severe eagle problems developed), the 76 percent eagle predation, and the 1974 docking per...
متن کاملModeling with uncertain science: estimating mitigation credits from abating lead poisoning in Golden Eagles.
Challenges arise when renewable energy development triggers "no net loss" policies for protected species, such as where wind energy facilities affect Golden Eagles in the western United States. When established mitigation approaches are insufficient to fully avoid or offset losses, conservation goals may still be achievable through experimental implementation of unproven mitigation methods prov...
