Abstract

The study of age structure and relative population density of the Mediterranean gecko (Hemidactylus turcicus L.) was conducted on the islands of Hvar and Vis during the period from 2002 until 2006. The total of twenty one locations on Vis and fifty one on Hvar were included in a transect and then visited once a month during the whole year. Individuals were counted in the morning, afternoon, evening and night during which time adult geckoes were distinguished from juveniles. The study results indicate that there are changes in the Mediterranean gecko’s daily and seasonal activities. The relative population density of adult geckos is significantly higher than the relative population density of the juvenile ones. The relative density of allopatric adult population on Vis is significantly higher than the relative density of sympatric adult population on Hvar. Also, lower population densities of the Mediterranean gecko on Hvar are caused by the occurrence of the Moorish gecko (Tarentola mauritanica L.) in habitats where they live together, but also from different habitat conditions on that island which is obvious from lower population density on locations where the Mediterranean gecko is solely present.
