On Anomalies of the Caudal Regeneration and Autotomy in Mediodactylus danilewskii (Reptilia: Sauria: Gekkonidae)

The paper presents data on the findings of three Danilewski’s gecko (Mediodactylus danilewskii) individuals with bifurcations of their regenerated tails in the Karadag Reserve (the southeastern Crimea). Possible causes of such an abnormality are discussed.

INTRODUCTION OF AMPHIBIANS AND REPTILES IN THE CAUCASUS AND CRIMEA: AN OVERVIEW AND SOME ACTUAL DATA

An overview of the cases of introduction (both accidental and intentional) of amphibians and reptiles in the Caucasus and Crimea is provided. The introduction cases are systemized in accordance with the goals and ways of introduction and with regards to the expected scale of the impact and its nature. No negative consequences of the introduction of amphibian and reptile species in the Crimea and Caucasus are currently observed on any of the known examples. No cases of species naturalization, which the “invasion” term can be applied to, have been revealed.

PRELIMINARY DATA ON THE MOLECULAR GENETIC STRUCTURE OF PELOPHYLAX RIDIBUNDUS (AMPHIBIA: ANURA: RANIDAE) FROM THE SOUTHERN PART OF THE CRIMEAN PENINSULA, BASED ON MITOCHONDRIAL AND NUCLEAR DNA ANALYSIS

Molecular genetic analysis of 28 marsh frogs Pelophylax ridibundus complex from 12 localities of the Crimean peninsula was conducted by two molecular markers, namely, COI, the gene of the first subunit of cytochromeoxydase mtDNA, and SAI-1, the first intron of the serum albumin gene nDNA. It has been found that the mtDNA type specific for the “eastern” form (the Anatolian P. cf. bedriagae) prevails for the Crimean marsh frogs, while the mtDNA type of the “western” form (the Central-European P.
