Observations of Paedomorphic Newts (Triturus vulgaris) from the Former Soviet Union

Spartak N. Litvinchuk, A. M. Rudyk, Leo J. Borkin


The reliable data on paedomorphosis in two subspecies of the common newt Triturus vulgaris lantzi (Abkhazia, western Caucasus) and T. v. vulgaris (the vicinity of St. Petersburg) are given for the first time for the former Soviet Union. Data on the appearance, occurrence, development and distribution of paedomorphic larvae are given based on field and laboratory observations beginning in 1986. The life cycles of paedomorphic and metamorphosed newts are discussed.
