a: LDA based on the groups of faunistically similar leech assemblages, dominated by the Haemopis sanguisuga (1), Placobdella costata (2) and Dina dinarica (3) groups. (for codes of species presented on the plots refer to Appendix 2); b: LDA based on groups of communities that occur in different types of springs (L – limnocrene; R-L – rheo-limnocrene; SL – sublacustrine; R – rheocrene; C – caves, for codes of species presented on the plots refer to Appendix 2).
