Data for: Invasion history of Lycium ferocissimum in Australia – the impact of admixture on genetic diversity and differentiation
<p class="MsoNormal"><strong><span>Aim:</span></strong><span> We investigated the invasion history of <em>Lycium ferocissimum</em>, a spine-covered shrub native to South Africa that has developed into a damaging invasive plant of undisturbed landscapes and pastures across southern and eastern Australia. In addition to identifying the provenance of the Australian plants, we tested for evidence of admixture, and contrasted genetic diversity and structuring across the native and introduced ranges.</span></p> <p class="MsoNormal"><strong><span>Location: </span></strong><span>Samples were collected across South Africa (24 localities) and Australia (26 localities).</span></p> <p class="MsoNormal"><strong><span>Methods:</span></strong><span> We used genotyping-by-sequencing (3,130 SNPs across 381 individuals) to assess population genetic structuring in <em>L. ferocissimum </em>across Australia and South Africa. Coalescent analyses were used to explicitly test contrasting invasion scenarios.</span></p> <p class="MsoNormal"><strong><span>Results:</span></strong><span> Clear geographic genetic structuring was detected across South Africa, with distinct clusters in the Eastern and Western Cape provinces. The <em>L. ferocissimum</em> plants in Australia form their own genetic cluster, with a similar level of genetic diversity as plants in South Africa. Coalescent analyses demonstrated that the lineage in Australia was formed by admixture between Eastern Cape and Western Cape plants, with analyses suggesting that plants from both African regions were originally introduced to South Australia. We detected little evidence of geographic genetic structure across Australia, although many of the populations were genetically distinct from one another.</span></p> <p class="MsoNormal"><strong><span>Main conclusions</span></strong><span>: Our results illustrate how admixture can result in genetically diverse and distinct invasive populations. The complex invasion history of <em>L. ferocissimum </em>in Australia poses particular challenges for biological control. We suggest potential biological control agents should be screened against admixed plants (in addition to plants from the Eastern and Western Cape) to test whether they provide effective control of the genetically distinct invasive lineage.</span></p>
Origin and genetic variability of populations of the invasive plant Rumex alpinus L. in the Giant (Krkonoše) Mountains
<p><span>Monk's rhubarb, <em>Rumex</em> <em>alpinus</em> L. (<em>R. alpinus</em>), is a perennial plant native to the mountains of Central and Southern Europe. Currently, the distribution of <em>R. alpinus</em> has been partly affected by its utilization as a vegetable and a medicinal herb. In the mountains of the Czech Republic, it is considered an invasive plant, probably introduced into the Krkonoše Mountains by colonists from the Alps. </span></p> <p><span>This study's main aim was to verify whether <em>R. alpinus</em> was introduced into the Krkonoše Mountains by alpine colonists or whether it was anthropogenically introduced from the Carpathians. Furthermore, the genetic structure of native and introduced populations of <em>R. alpinus</em> was determined.</span></p> <p><span>For the evaluation of genetic structure, 417 samples of <em>R. alpinus</em> were collected from the Alps, Carpathians, Balkan, Pyrenees, and Czech Mountains. In total, 12 simple sequence repeat (SSR) markers were applied.</span></p> <p><span>The results of AMOVA showed a high 60% variation within populations, 27% variation among groups, and 13% among the population within groups. The overall unbiased gene diversity was high (ĥ = 0.55). The higher level of genetic differentiation among populations (<em>F</em><sub>ST</sub> = 0.35; <em>p</em> < 0.01) indicated restricted gene flow between populations. Compared to native populations, limited genetic variability was observed in the nonnative populations. It was concluded that local adaptation, low gene exchange, and genetic drift affected the genetic diversity of nonnative <em>R. alpinus</em>.</span></p> <p><span>The results support a genetic link between Alpine and Czech genotypes of <em>R. alpinus</em>, while the Carpathians genotypes corresponded to the Balkan genotype.</span></p>
