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
