DISTRIBUTION AND STATE OF THE BOMBINA BOMBINA POPULATIONS ON THE NORTH-EASTERN MACROSLOPE OF UKRAINIAN CARPATHIANS Smirnov N. A. Department of Nature, Chernivtsi Regional Museum UKRAINE [email protected]

Fire-bellied toad Bombina bombina (Linnaeus, 1761) is a widespread and numerous amphibian species on almost part of territory of Ukraine. This species is lack in South-Eastern Ukraine (Pysanets, 2014) and in mountain regions of the Ukrainian Carpathians, where inhabit the relative species – B. variegata (Linnaeus, 1758). The borders of areas these two species situates on both, South-Western and North-Eastern, macroslopes of Carpathians (Reshetylo, 2001; Kuzmin, 2012; Pysanets, 2014). B. bombina inhabits open lowland plots on the territory of North-Eastern macroslopes of Ukrainian Carpathians (135–410 m a. s. l.). It is common amphibian species in upper part of Dnister and Vistula rivers basin. This species was found in 41 localities from 15 administrative district (Halych, Kosiv, and Sniatyn districts of Ivano-Frankivsk region, Horodok, Drohobych, Zhydachiv, Mykolaiv, Mostyska, Sambir, Skole, Stryi, and Yavoriv districts of Lviv region, Kitsman, Novoselytsia, and Storozhynets districts of Chernivtsi region). Roadside ditches, puddle ruts, ponds, reclamation channels, lakes, decorative ponds are almost typical B. bombina habitats in region of investigation. The abundance of the B. bombina in these habitats is 0.01–14.29 individuals per m2 (Mean 2.46, St.Err. 1.06, N = 14). The main factors of negative impact on the B. bombina populations are drying of breeding ponds, habitat pollution and destruction. B. bombina often uses for spawning ephemeral (33.3 %) or seasonal (46.7 %) ponds which have small size (Mean 298.6 m2, St.Err. 248.5, N=14) and shallow maximal depth (Mean 0.49 cm, St.Err. 0.30, N=15). They dry up in a few weeks (or days) after rain often. Therefore, eggs and tadpoles die in such ponds before they finish metamorphosis.
