Fig 5. Cases of ambiguity.

A) The two recognized subspecies of S. salamandra form two distinct clades but contribute to the same BIN. B) I. alpestris is represented by only one BIN despite increased intraspecific distance and a subdivision into separate clades. C) Presumed subspecies of P. muralis. Austrian samples are found in the three clades recovered by [7], but also in the “Central Balkan clade” proposed by [65] and another Austria specific BIN. D) Conspecific lineages within R. temporaria represented by two distinct BINs. E) Discrepancies within N. natrix. Two separate BINs were recovered within the nominal form N. n. natrix, as well as one new BIN from Austria. N. helvetica forms a distinct clade with an individual BIN. F) High genetic diversity within Z. vivipara. The separate clades and distinct BINs likely correspond to various genetic lineages proposed by [58].
