In 2018 we estimated the population size of the hybrid population of Italian crested/Danube crested newt (Triturus carnifex/dobrogicus) in the Zaton oxbow lake, Petanjci (Natura 2000 »Mura«, SAC SI3000215 & SCI SI5000010). The Ortmann traps were set in the lake for ten consecutive days during the reproductive season. We used the mark-release-recapture method by comparing photographs of individually specific belly patterns of the trapped newts. The estimated Italian crested/Danube crested newt population size in the Zaton oxbow lake was 2,951 individuals (95 % confidence interval: 2,226–3,977 individuals).
