Morphological diversity and relationships of Scardinius dergle and Scardinius plotizza populations (Actinopteri; Cypriniformes) from Croatia and Bosnia and Herzegovina

Genus Scardinius (Cypriniformes, Actinopteri) belongs to the family Leuciscidae, subfamily Leuciscinae, and it includes 10 species. Phylogenetic morphometric research conducted so far have shown a great taxonomic complexity within this genus. Therefore, aim of was determine morphological diversity contribute clarification relationships status S. dergle plotizza. For purpose specimens plotizza were collected from their whole distribution area in Croatia Bosnia Herzegovina. On each individual 25 characters measured, standardized with allometric conversion analysed using descriptive inferential statistics. Results showed significant intra- interspecific differences investigated characters. In addition, distinct grouping populations species partial overlapping some both recorded, reflecting possible relationships. Also, meristic accordance deterministic values for most populations. Although has given indications plotizza, order confirm results exact status, phylogenetic genetic these species, further is needed.
