Abstract

Along with decrease in numbers among amphibians in Eastern Europe nowadays newts especially suffer from invasive predatory fish and turtles. Such aggressive predator as P. glenii has recently occupied water bodies important for newts' breeding. The fish eat eggs, larvae and even adult individuals. Using the ecological niche approach, it was showed that for built distribution models based on certain climatic scenario Coefficient of determination (R 2) between Chinese sleeper and preserved T. cristatus with L. vulgaris to 2090 will grow from 44% to 66% in Eastern Europe highlighting expanding of new territories by the fish as a real threat to biodiversity.
