Abstract


In southeastern Kazakhstan, the tetraploid toad Bufo danatensis is a widespread and common species both in lowlands and in mountains, unlike the diploid toad B. viridis. Tetraploids were recorded at many low elevations in deserts and steppes. In the area between Chu and Ili rivers, diploids are replaced by tetraploids. This is a horizontal replacement zone in lowlands. In northern Kyrgyzstan and other regions of the former Soviet Middle Asia, replacement zones exist along vertical transition from lowlands to mountains. Few localities with triploids (males) were found in the Chu and Ili River area. Bufo danatensis is recommended to exclude from the Red Data Book of Kazakhstan.
