Comparative embryotoxicity of a pentabrominated diphenyl ether mixture to common terns (Sterna hirundo) and American kestrels (Falco sparverius).
Concentrations of polybrominated diphenyl ethers (PBDEs) in Forster's tern (Sterna forsteri) eggs from San Francisco Bay have been reported to range up to 63μgg(-1) lipid weight. This value exceeds the lowest-observed-adverse-effect level (1.8μgg(-1) egg wet weight; ∼32μg(-1) lipid weight) reported in an embryotoxicity study with American kestrels (Falco sparverius). As a surrogate for Forster'...
متن کاملCalibrating the telomere clock in common terns, Sterna hirundo.
Field biologists often work with animals for which there are no prior history. A marker of an animal's age would offer insight into how age and experience affect reproductive success and other life history parameters. We previously reported that length of telomere restriction fragments shorten predictably with age in the captive zebra finch (Taeniopygia guttata). This paper reports that telomer...
متن کاملEmbryonic exposure to the polybrominated diphenyl ether mixture, DE-71, affects testes and circulating testosterone concentrations in adult American kestrels (Falco sparverius).
Polybrominated diphenyl ethers (PBDEs) are additive flame retardants that are environmentally persistent and bioaccumulative. The developmental effects of in ovo exposure to environmentally relevant levels of the PBDE technical mixture, DE-71, on male reproductive physiology in captive American kestrels (Falco sparverius) was determined. Males were exposed in ovo by direct maternal transfer to ...
متن کاملChanges in reproductive courtship behaviors of adult American kestrels (Falco sparverius) exposed to environmentally relevant levels of the polybrominated diphenyl ether mixture, DE-71.
Polybrominated diphenyl ethers (PBDEs) are increasing in biota. Here, captive adult American kestrels were exposed daily by diet to safflower oil (controls), or one of two levels of a pentaBDE technical formulation, DE-71 (0.3 or 1.6 ppm), for approximately 75 days, commencing 21 days before breeding. This exposure resulted in eggs having PBDE concentrations similar (low exposure) or within the...
متن کاملComparative Toxicity of Diphacinone to Northern Bobwhite (Colinus virginianus) and American Kestrels (Falco sparverius)
The acute oral toxicity of the anticoagulant rodenticide diphacinone was found to be about 20 times greater to American kestrels (LD50=97 mg/kg) than to northern bobwhite (LD50=2,014 mg/kg). Several precise and sensitive clotting assays (prothrombin time, Russell’s Viper venom time, thrombin clotting time) were adapted for use in these species, and this combination of assays is recommended to d...
