Potential Threat of an Invasive Fish Species for Two Native Newts Inhabiting Wetlands of Europe Vulnerable to Climate Change

In the modern world, when problems of environment are most acutely associated with climate change, amphibians considered to be vulnerable group anamniotes as an indicator state wetlands. Along a decrease numbers among in Europe, nowadays newts especially suffer from impact invasive species, particular predators such Chinese sleeper, Perccottus glenii. This predatory fish species has recently spread areas primary relevance for newt reproduction. consumes eggs, larvae, and even adult individuals. Using ecological niche approach based distribution models (SDM), we applied coefficient determination (R2) comparing level similarity built SDM Triturus cristatus Lissotriton vulgaris, sleeper. We show that by 2050, climatic these native will increase 12% 22% throughout 44% 66% Eastern Europe. study highlights expansion sleeper real threat European biodiversity wetlands near future, their northeastern range.
