This study provides distribution data for 12 species of reptiles in the Southern Bug eco-corridor located within the steppe zone, Mykolaiv Oblast (province), Ukraine. We compiled 935 records from published literature (324), from public databases (68), and from 12 field surveys we made in 2016–2020 (543). All records were mapped on to a grid of 10×10 km, representing the 294 cells of the studied area. We present new distributional data for Podarcis tauricus. For all the other species, our records add new localities that fall within areas where these reptiles were previously reported. Species richness and Shannon’s H’ index show that herpetofauna diversity was higher in the areas along the Southern Bug River. The maximum number of records within a single cell was 118 (for 10 species) in this oblast. Also the high number of identified reptile chorotypes (nine) within the Mykolaiv Oblast revealed that southern Ukraine is an important zoogeographical territory in Europe. These data provide the basis for future biogeographical and ecological studies and conservation priorities.

乌克兰南部Bug生态走廊内爬行动物分布的第一份综合数据

这项研究提供了位于乌克兰Mykolaiv州（草原）草原地区南部Bug生态走廊中12种爬行动物的分布数据。我们从公开发表的文献（324），公共数据库（68）和我们在2016-2020年进行的12次现场调查（543）中汇总了935条记录。所有记录都映射到10×10 km的网格上，代表研究区域的294个单元。我们提出了Podarcis tauricus的新分布数据。对于所有其他物种，我们的记录添加了新的地点，这些地点位于先前报告过这些爬行动物的区域内。物种丰富度和Shannon's H'指数表明，南部布格河沿岸的带状疱疹物种多样性较高。在该州中，单个细胞内的最大记录数为118（对于10个物种）。此外，在Mykolaiv州内发现的大量爬行动物染色体型（九种）表明，乌克兰南部是欧洲重要的动物地理区域。这些数据为将来的生物地理和生态学研究以及保护重点提供了基础。
