Abstract: During a long-term study (1987-1996) near Vienna (Austria), individual Danube crested newts ( Triturus dobrogicus) and common spadefoot toads (Pelobates fuscus) were registered by photographs of highly variable skin patterns, and the implantation of Passive Integrated Transponders (PIT tags). To test for potential detrimental effects of the electronic tags, we compared within-year (for P. fuscus) and between-year (for T. dobrogicus) recapture rates and body condition index (Cl) of individuals marked with the two alternative techniques. No significant negative effects of PIT tags on Cl and recapture rate could be demonstrated for either species. There was a decrease in body condition and recapture rates in the study years 1995 and 1996, but can be attributed to population trends rather than to the different marking methods. For recaptured T. dobrogicus a I 0.5% loss of PIT tags was observed.
