Abstract: | In this work we assessed the genetic diversity of 32 C.?calceolus populations from Poland. Mean genetic diversity was moderate (P?=?36.4%, A?=?1.58, H O?=?0.143, F IS?=?0.059), and seven geographic regions did not differ significantly in their levels of polymorphism (p?>?0.05), although allele frequencies varied greatly. Only four unique alleles were found, at three sites in southern and southeastern Poland. Genetic (P, A) and genotypic diversity parameters (G, G U) were significantly correlated with population size (p?<?0.001). In the 32 studied populations we separated 422 different multilocus genotypes; none was common to all populations. Overall population differentiation was moderate at 0.137 (p?<?0.001), but we found a significant pattern of isolation by distance for the whole dataset (r 2?=?0.65, p?<?0.001). Our chloroplast DNA (cpDNA) results suggest a single evolutionary lineage and a common origin for all Polish C.?calceolus populations. Information about the genetic health of C.?calceolus populations should be useful in developing conservation strategies. |
