The different data sets yielded largely congruent cladograms. Vipera berus from Sweden was included as an ingroup and V. aspis was used for outgroup comparison. For V. kaznakovi and V. dinniki , three and four different sub‐populations, respectively, were treated as independent terminal taxa in the analyses. The most parsimonious cladograms confirmed the systematic positions of these populations, discussed in a recent study, and support the hypothesis that the montane populations of the western main Caucasus comprise one polymorphie species: V. dinniki. Analyses of combined biochemical and morphological data generated two equally parsimonious cladograms (for all ingroups compared), but yielded only one fully resolved topology when ingroups were condensed to the species level: ( berus ((renardi (‘ursinii’‐eriwanensis )))( dinnikikaznakovi )).Read More
