Sažetak
Astacus astacus is one of four native crayfish species inhabiting Croatian freshwaters. It is known that they play a key role in the ecosystems functioning, that their populations are declining and that they are vulnerable. In order to develop adequate conservation programs for their preservation, sound knowledge of their biology and ecology is necessity. It is known that organisms adapt to specific environmental conditions in different ways and that some of these adaptations can also affect their morphology. The aim of this research was to study morphological characteristics of A. astacus, and to compare populations from different regions in Croatia. Study included 230 individuals belonging to different water basins/ water body types/mtDNA phylogroups. Analyses were conducted using geometric morphometrics approach, comprising 34 landmarks on the dorsal side of crayfish cephalon. Results revealed that morphometry differs among phylogroups, among river basins and also between water body types.
