Male and Female Cloacal Anatomy of the Fischer’s Clawed Salamander, Onychodactylus fischeri (Caudata, Hynobiidae)
Autor: Irina V. Maslova, Darya A. Rogashevskaya, Sophiya S. Evseeva, Vadim V. Yartsev
Publikováno v: Russian Journal of Herpetology. 28:275-280
The cloaca of salamanders is a complex organ with exocrine glands involved in the production of sex pheromones, spermatophores, and storage of sperm. Since the cloaca provides reproductive functions, its signs are important for phylogenetic analysis

Sexual Variability of Histological Skin Parameters of Salamandrella keyserlingii (Amphibia, Caudata) in the Aquatic and Terrestrial Phases of its Seasonal Cycle
Autor: Sophiya S. Evseeva, Vadim V. Yartsev
Publikováno v: Current Studies in Herpetology. 20:100-106
Histological features of the dorsal (DS), throat (TS) and tail skins (caudal skin, CS) were examined in Salamandrella keyserlingii females of the aquatic and terrestrial morphotypes. Using histological and statistical methods, sexual differences in t

Reproduction features of the common lizard, Zootoca vivipara (Lichtenstein, 1823) (Sauria, Lacertidae) from different high-altitude zones of the Kuznetsk Alatau
Autor: Valentina N. Kuranova, Western Baikal Protected Areas, Vadim V. Yartsev, Lidia A. Epova
Publikováno v: Vestnik Tomskogo gosudarstvennogo universiteta. Biologiya. :79-100
In order to identify the specific features of mountain populations of the wide-range species of reptiles Zootoca vivipara, we analyzed various aspects of reproduction. This is the key process that ensures the existence of the species in extreme mount

The Male Urogenital System of a Salamander Ranodon sibiricus (Amphibia, Caudata)
Autor: Sophiya S. Evseeva, Vadim V. Yartsev
Publikováno v: Current herpetology. 2021. Vol. 40, № 1. P. 10-21
The male urogenital system of salamanders varies both among families and within them. To understand diversity of this system in hynobiids, we studied the gross anatomy and histology of the male urogenital system of a mountainous rheophilic salamander

Sperm morphology in two cryptic species of the genus Salamandrella (Caudata: Hynobiidae)
Autor: Vadim V. Yartsev, Galina S. Martynova, Valentina N. Kuranova
Publikováno v: Vestnik of Saint Petersburg University. Series 3. Biology. :18-30
We conducted a light microscopy study of the sperm morphology in two species of salamanders of the genus Salamandrella. We analysed the acrosome length, width, length and volume of the head, tail and total sperm lengths. Via canonical and factor anal
