Global contamination with organochlorine compounds (OCs) has posed developmental and reproductive problems in wildlife worldwide. However, little is known about the impact of OCs or other pollutants on amphibians, despite mounting concerns about amphibian population declines and developmental deformities in the wild. Wildlife populations may be affected critically by sublethal impacts of anthro...

I described the tactile-stimulated startle response (TSR) of wood frog (Rana sylvatica), bullfrog (Rana catesbeiana), and American toad (Bufo americanus) tadpoles. One purpose was to rank species in terms of maximum acceleration performance. Also, I tested whether anatomical indicators of performance potential were predictive of realized performance. TSRs were elicited in a laboratory setting, ...
