Abstract

The purpose of this thesis was to determine the genetic structure and phylogenetic relationships among mediterranean toothcarp, Aphanius fasciatus (Valenciennes, 1827) populations from sites not included in similar investigations to date. Two genetic markers were sequenced and a number of nucleotide sequences corresponding to the cytochrome b gene (1.140 base pairs) and mitochondrial region (396-398 base pairs) were obtained. Individuals were collected from eight different localities in Slovenia, Croatia, Monte Negro and Albania. A. fasciatus sequences available from previous investigations, as well as those from other species of the genus Aphanius, were also included. Low genetic diversity was observed within the populations and a higher genetic diversity between the populations. The molecular analyses show that the studied populations belong to an evolutionary line independent from the other species. They are genetically and spatially distinct and can be separated into a northern and a southern group of sites, corresponding to the northern and southern Adriatic.
