An Overview of Historical Distribution Patterns of Chalcides ocellatus (Forsskål, 1775) Using Ecological Niche Modelling: the Taurus Mountains as a Refugium

Kamil Candan, Çetin Ilgaz, Yusuf Kumlutaş, Serkan Gül


The Taurus Mountains that have a very rich biodiversity are one of the most important mountain chains in Anatolia. In this study, we examined distribution patterns of Chalcides ocellatus that has a restricted dispersal between the Taurus Mountains from the past to current using ecological niche modeling. The Taurus Mountains have played the role as a refugium area in which C. ocellatus could survive through a period of unfavorable conditions. Especially in the glaciation period, Amanos Mountains in the Middle Taurus as an isolating barrier appeared unsuitable habitats for the lineages of C. ocellatus. This indicated that the lineages of C. ocellatus were formed as a result of habitat fragmentation during the last glacial maximum and last interglacial, and were consequently adapted to different climatic conditions.
