The Unusual Winter Activity and Negative Effects of Pollution on Breeding of Ommatotriton ophryticus (Berthold, 1846) in Turkey

Abstract

The northern banded newt, Ommatotriton ophryticus (Berthold, 1846) is a poikilotherm (ectoterm) and hibernating amphibian species. Therefore, the records related to the winter activities of Ommatotriton ophryticus are very rare. In the present study, a winter activity belonging to Ommatotriton ophryticus was recorded in a channel containing stagnant water throughout the year in the province of Trabzon. It was observed that the newts were active during the winter season, between December 2017 – March 2018. In the water environment where the study was carried out, the population density of newts was high and the numbers of male individuals were higher than that of females. Additionally, some female individuals were observed as gravid. Environmental pollution is a source of stress for amphibians. It was observed that the newts which did not hibernate during a winter period and performed their breeding activities in the water as a result of the acute contamination due to pesticide use in their water environment at the end of March 2018 left the aquatic environment which they used for breeding. Although the area was subsequently visited at different times, these newts were never seen again and no information was obtained on whether the animals had gone to another aquatic environment. Urgent measures should be taken against the pollution caused by pesticides, which have a clearly negative impact on animals.
