Abstract: The present study provides data on the abundance of syntopic southern crested newts, Triturus karelinii, and banded newts, Triturus vittatus, in Uludağ National Park. The population of T. karelinii was 275 ± 60.9 (95% CI = 138-413) in Kirazlıyayla and 424 ± 85.6 (95% CI = 212-636) in Sarıalan. The populations of T. vittatus in Kirazlıyayla and Sarıalan were 392 ± 85.6 (95% CI = 196-588) and 158 ± 37.9 (95% CI = 79-237), respectively. T. karelinii populations had an approximately balanced sex ratio in all ponds. In Kirazlıyayla 2 and Sarıalan ponds the sex ratio of T. vittatus was balanced, whereas it was female-biased in the Kirazlıyayla 1 pond.
