Low population differentiation and high genetic diversity in the invasive species Carduus acanthoides L. (Asteraceae) within its native range in the Czech Republic

Popis výsledku v původním jazyce

Population genetic diversity of Carduus acanthoides was expressed by assessing patterns of variation at nine putatively neutral allozyme loci within and among 20 natural populations in its native distribution range in the Czech Republic. Overall, C. acanthoides displayed high levels of genetic diversity compared to other herbaceous plants. The percentage of polymorphic loci was 84.5, with values of 2.37, 0.330, and 0.364 for the mean numer of alleles per polymorphic locus (A), observed heterozygosity (Ho), and expected heterozygosity (He), respectively. There was only weak evidence of inbreeding within populations (Fis = 0.097) and very low genetic differentiation among populations (Fst = 0.085). Analyses of the data provide strong evidence for isolation-by-distance for the whole study area. Even the colonizing species, C. acanthoides, currently supports a substantial amount of allozyme variation at both the species and population levels.
