Sažetak
The comprehensive research on population genetics and morphological characteristics of the white‐clawed crayfish from Adriatic Basin was conducted. We present results that include analyses of three populations (Rječina (RJE), Reka (REK), and Glinščica (GLI) rivers), in which an unexpected genetic pattern was observed. Despite the current geographical isolation of these three populations, results of genetic analyses grouped them into the same cluster. The obtained genetic structure could be a consequence of human‐mediated translocations, or a consequence of natural dispersal. Natural dispersal is the most probable cause of obtained structure for several reasons ; Observed moderate values of expected heterozygosity (He =0.34 in GLI, =0.36 in REK, =0.44 in RJE) were not likely to appear in newly established populations after human‐ mediated translocations. Further, the connection between the Reka and Rječina rivers was recognized based on the distribution of Niphargus species. Finally, according to geographical position and hydrology of examined rivers, natural dispersal could appear due to historical headwater river captures or due to dispersal of crayfish through underground water systems. The last possibility should be taken into consideration because it is not unusual to find the white‐clawed crayfish and its congeneric species, the stone crayfish, very deep inside cave systems.
