Herpetofauna of Sevastopol city (southwestern Crimea): species composition, zoogeographic analysis, landscape-zonal distribution, current status and protection
This work summarizes information on the distribution and status of the populations of amphibians and reptiles of the city of Sevastopol. Data obtained over a quarter of a century were refined by a targeted herpetological examination of the entire territory of Sevastopol (over 1000 km2 ) in 2018 and...
