Description:
Changes in solar ultraviolet (UV) radiation have been proposed as a possible factor contributing to seeming increases in hindlimb malformations in anuran amphibians in North America. A primary purpose of this study was to reproduce results from an earlier experiment in which Rana pipiens (northern leopard frog) developed handlimb ectromelia and ectrodactyly when exposed to an artificial source of UV light in the laboratory. . . Due to uncertainties in dose exprapolation, particularly in the context of animal behavior, the potential significance of our results in terms of explaining adverse effects in amphibians from the field is as yet unclear.
