WHO IS WHO? Interactive individual identification system (I3S software) as a tool for non-intrusive identification of an endemic lacertid species, Mosor Rock Lizard, Dinarolacerta mosorensis

Marking individuals is often needed in field and behaviour studies that required repeated identification of individual animals. With the development of technology, older methods like scale or toe clipping, branding, painting, tagging, banding are slowly being replaced by technology facilitated identifications. In last decade non-intrusive and inexpensive digital identification of individual animals become popular and with these method large sets of individuals can be re-identified. I3S Software is originally developed for identification of sharks but has successfully been already used for identification of Lacertidae lizard species. Mosor rock lizard is an endemic species of western Balkans. It’s area of occurrence is approximated to be less than 2000 km2. It is also a Natura 2000 species. In 2017, an extensive study of its population parameters and biology has started on Mt. Biokovo, Croatia. To facilitate the correct identification of each individual, we used the program Interactive Individual Identification System. Photographs of first four rows of ventral scales of the lizard body were used for identification and comparison. Preliminary results based on 30 individuals were satisfactory, and all the individuals could be distinguished successfully by the program. With larger datasets, it is possible that the identification could be more time consuming, but in that case, additional parameters like sex or colorations may be used for correct identification.
