specific diversity

Specific composition, numbers and biotopical distribution of snakes (Serpentes) on the southern slope of the Navagir mountain ridge (Abrau Peninsula) and some problems of its preservation

Seven species of snakes were revealed in 1997–1998, six of which (Natrix tessellata, N. natrix, Zamenis longissimus, Hierophis caspius, Platyceps najadum, and Elaphe sauromatus) were in the lower part of the slope, in the area of mediterranean vegetation. In 2001–2003, the first three species were revealed only, and their numbers significantly decreased, reaching a maximum in the middle part of the slope, in the zone of transition from mediterranean vegetation to broad-leaved forests.

Authors: Bondarenko D. A., Peregontsev E. A.

Terrestrial route counts of reptiles in 24 localities of the plateau Ustyurt were carried out in 2007 - 2008. 474 individuals of 15 species were found along a total of 243.5 km passed. Based on the results of our survey, the reptile population structure has been clarified in 12 landscapes. The low specific diversity and population density of reptiles were observed everywhere. 2 to 8 species with a population density of 1.9 - 8.4 individuals per ha were found in certain landscapes. In terms of abundance, the reptiles belonged to rare or common species.

Authors: Zamaletdinov R. I.

During the field season of 2014, research was conducted on 5 areas planned for organizing protected areas in Kazan City. The examined areas were found to be important for preserving the diversity of amphibians and reptiles in the city. Of major concern is preservation of the northern crested newt (Triturus cristatus Laurenti, 1768) and the common toad (Bufo bufo, Linnaeus, 1758) in those territories, the species listed in The Red Data Book of the Republic of Tatarstan.
