Authors: Chikhlyaev I. V., Askenderov A. D., Faizulin A. I.

The helminth community of the Green toad Bufotes viridis (Laurenti, 1768) from the population inhabiting the Caspian basin on the territory of the Republic of Dagestan is characterized. The study was carried out according to the method of full helminthological autopsy. Six species of helminths belonging to two types have been registered: Nematoda (4) and Acanthocephala (2).

Variability of morphophysiological parameters of green toads of the Bufotes viridis complex (Anura, Amphibia) depending on altitude zoning

Authors: Gamidova D. M., Askenderov A. D., Rabadanova A. I.

In Dagestan, morphometric parameters of the body and cytomorphological parameters of erythrocytes were studied in 124 green toads from four regions. In the course of the analysis of variance, variability between populations in these parameters was revealed, which is associated both with the influence of altitudinal zonality, sex, and the interaction of these factors.

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.
