Abstract

Species of freshwater crayfish of the familiy Astacidae are divided in three genera and are indigeniuos to Europe (genera Astacus and Austropotamobius) and western North America (genus Pacifastacus). There are four native Croatian crayfish species of the family Astacidae. Phylogenetic relationships among different populations of some of these species are not yet completely resolved. In this research morphological characteristics and phylogenetic relationships of 61 individuals were studied. The crayfish were collected from nine sites situated in Žumberak - Samoborsko gorje Nature Park. Mitochondrial genes were used for molecular phylogenetic analyses and in morphological aspect of research we measured morphometrical and meristic characteristics, which were then grouped in accordance with the results of previous genetic analyses and processed with statistical methods. Obtained results show a large genetic diversity of studied populations and statistical analyses of morphological data show significant differences for geographically separated populations. Such high genetic diversity and morphological variation present an unique phenomenum on the European scale and will probably demand special care and protection in the near future.
