Relating Invasibility and Invasiveness: Case Study of Impatiens parviflora

Data on alien species show that plant invasions are caused by a complex combination of characteristics invasive (invasiveness) and invaded environment (invasibility). Impatiens parviflora is one Europe’s top species. The present study aimed to evaluate molecular diversity populations highly in Lithuania I. applying several DNA markers relating genetic parameters abiotic biotic environment. For sampling, urban forests, riparian agrarian shrublands were selected. Three different DNA-based techniques, Simple Sequence Repeats (SSR), Inter Repeat (ISSR) markers, Random Amplified Polymorphic (RAPD), used for detecting variation between 21 populations. All population individuals monomorphic homozygotic four loci heterozygotic locus SSR analysis. Hierarchical analyses variance at ISSR RAPD revealed significant differentiation depending geographic zones the country. Bayesian Structure data demonstrated existence many clusters this finding support multiple introduction polymorphism extent was positively correlated with total coverage herbaceous negatively number light sites. Our results indicate Lithuanian sites might be distinguished high soil nutrient levels. According principal component analysis, more important variable compared or In conclusion, complexity invasibility invasiveness factors determine variability sites, including traits, conditions interrelated.
