The paper presents the results of studying the reproductive biology of Darevskia daghestanica in the valleys of Khzanor and Kitlyarta rivers (Tsunta district, Republic of Dagestan, Republic of Dagestan). Adult females were caught in the II–III decades of May 2021. In the following, the animals were kept singly in a laboratory. Lizards laid eggs from the third decade of May to the second decade of June. The body length of breeding females was 43.95–56.20 mm.

Hybridization and distribution of cryptic species of green toads (Bufotes) (Bufonidae, Amphibia) in Republic of Dagestan (Russia)

Authors: Skorinov D. V., Rakitskaya T. A., Askenderov A. D., Mazanaeva L. F., Litvinchuk S. N.

Distribution of cryptic species of green toads (Bufotes viridis and B. sitibundus) in Dagestan still understudied. We used the nuclear (microsatellite BM224) and mitochondrial (fragment of the CytB gene) markers characterized by species-specific alleles and haplotypes, respectively. Alleles of B. viridis predominated in toad populations in the plains in the north of the republic, while B. sitibundus alleles were more numerous in more southern mountainous and coastal (the coast of the Caspian Sea southeast of Makhachkala) regions.
