Abstract. The diversity of habitats affects the maintenance of biological diversity and the stability of ecosystems. Therefore, study of the ecological characteristics of the species habitats have a great importance. The object in the scope of our research is the Crimean rock lizard (Darevskia lindholmi), an endemic of the Crimean Mountains. Its genetic structure includes three differentiated and spatially isolated mitochondrial lineages – the «Central», the «Southwestern», and the «Common». In addition, the range of the «Central» lineage divides the range of the «Common» one into two proportionate parts – western (the «Common West») and eastern (the «Common East») clusters. The goal of the study is to identify habitats conditions that affect the spatial distribution of four groups of the Crimean rock lizard’ populations. Correspondence analysis was used to examine the relationships between the indicators of occurrence of D. lindholmi groups (126 sites) and environmental factors (6 factors, 23 parameters). The results showed a fairly pronounced habitat differentiation of the four groups and allowed us to characterize the «Central» lineage as a group inhabiting the highest uplands with a developed river network and coniferous forests, while both clusters of the «Common» and the «Southwestern» lineages gravitate toward drier and more open habitats located at lower absolute altitudes.
