Abstract

The aim of this study was to delineate functional conservation units (FCUs) in Scarce Fritillary Euphydryas maturna (Linnaeus, 1758) populations in eastern Central Europe. We analyzed the level and structure of genetic variation using allozymes as markers in 26 Scarce Fritillary populations originating from nine geographic regions. Considering the reproductive strategy of E. maturna, we assumed that populations are strongly exposed to genetic drift. Accordingly, we hypothesized: (i) A low level of genetic variation within populations, and; (ii) A high level of differentiation among them with little evidence of geographic pattern. The results of this study mostly fulfilled our expectations: (i) Scarce Fritillary populations of eastern Central Europe exhibited a relatively low level of polymorphism at investigated enzyme loci, and; (ii) Comparatively strong differentiation was detected among populations. As opposed to our expectation, however, a more-or-less clear pattern of differentiation was revealed by the results of our Bayesian-clustering analysis. Four genetic regions were distinguished on the basis of their average cluster membership coefficients, specifically Dobrogea (Romania), North and East Hungary (composed of four geographic regions), Central and West Hungary (involving three geographic regions), and Transylvania. Three of these genetic regions were previously distinguished as separate subspecies, comprising E. maturna idunides (Central and West Hungary), E. maturna partiensis (North and East Hungary including Transylvania), and E. maturna opulenta (Dobrogea, Romania). These three putative subspecies can be considered as Scarce Fritillary FCUs in eastern Central Europe.
