详细

A new annotated list of amphibian and reptile species in the Caucasian ecoregion is proposed, including comments on their biogeography and conservation. The updated list includes 128 species of amphibians and reptiles. 18 amphibian species belonging to two orders are known there; half of them (nine species) being endemic. The Caucasian ecoregion is inhabited by 110 reptile species: 5 species being turtles and tortoises, and 59 and 46 species representing lizards and snakes, respectively. Among them, 32 species (44 subspecies) are endemic to the ecoregion.
