Abundance of syntopic newts, Triturus karelinii (Strauch, 1870) and Triturus vittatus (Gray, 1835), in Uludag National Park (Bursa, Turkey)

The present study provides data on the abundance of syntopic southern crested newts, Triturus karelinii, and banded newts. Triturus vittatus, in Uludag National Park. The population of T. karelinii was 275 +/- 60.9 (95% CI = 138-413) in Kirazliyayla and 424 +/- 85.6 (95% CI = 212-636) in Sarialan. The populations of T. vittatus in Kirazliyayla and Sarialan 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 Kirazliyayla 2 and Sarialan ponds the sex ratio of T. vittatus was balanced, whereas it was female-biased in the Kirazliyayla 1 pond.
