The impact of A. E. Kulakovskiy in the study of amphibian and reptile fauna

In the article by A. E. Kulakovsky "Species of animal and plant kingdoms known to the Yakuts", written in 1912 and published in the journal of the Yakut branch of the Russian geographical society "Sakha keskile", four species from the orders amphibians and reptiles were described. In description of the names of each species he gives the geographical points of collection. This information was the first to describe the fauna of these orders. In his work, A. E. Kulakovsky for the first time gives the area of the viper - Vivera berus L., 1758 -, limiting its distribution North to the Sinyaya river. The given Yakut names of a viper - моҕой, эриэн кыыл, эриэн үɵн - are still used at the present time, but the most often - эриэн үɵн. The second species - a viviparous lizard - L. vivipara L. 1758 - was described by A. E. Kulakovsky as a large striped spotted lizard - күлгэри, күлгэли - living in Central Yakutia and in the vicinity of village Abyi. However, to date the range of this species in Yakutia has not been studied enough to the present date. Local Yakut people still often confuses viviparous lizard with siberian salamander. Therefore, the survey data on the distribution of viviparous lizards should be treated with caution. Siberian frog - Rana amurensis Boulenger, 1886 - is given in the work of A. E. Kulakovsky as a grass frog - Rana temporaria L., 1758. This species name was due to the existing classification of amphibians. According to modern taxonomy, the frog that lives East of the Yenisei river belongs to the siberian frog - Rana amurensis. Yakut names of this frog given by A. E. Kulakovsky - баҕа, алчах, сыыллар, дыгысках - apply now. The most widespread name is баҕа. Siberian salamander - Hynobius keiserlingi (Dybowski, 1870) - was described by A. E. Kulakovsky as a lizard - тыймыыт, силис мундута - Salamandrella heyserling L., 1758. Yakut names of siberian salamander - тыймыыт, силис мундута, given by A. E. Kulakovsky, are widely distributed and apply now. The fact that A. E. Kulakovsky attributed siberian salamander to lizards was due to the lack of scientific data on this species of Yakutia. In addition, local people almost do not distinguish between siberian salamander and viviparous lizard. According to A. E. Kulakovsky, siberian salamander lives in Central Yakutia and up to the upper reaches of the Indigirka river. According to modern data, the areal of siberian salamander occupies the entire forest and forest-tundra zones up to 71o North. The sharp-faced frog - Rana arvalis Nilsson, 1842 and the far eastern frog - Rana chensinensis David, 1875 are the new species for Yakutia, which began to populate the reservoirs of Southern and South-Western Yakutia at the end of the twentieth century.
