“…Both types of selection, either from new mutations or from standing variation, have been suggested in the context of plant invasions (Dormontt et al . ). Our results suggest that selection on standing variation in flowering time genes predominated during the early stages of colonization in S. austriacum for two reasons.…”

Rapid genetic adaptation precedes the spread of an exotic plant species

Human activities have increasingly introduced plant species far outside their native ranges under environmental conditions that can strongly differ from those originally met. Therefore, before spreading, and potentially causing ecological and economical damage, non-native species may rapidly evolve. Evidence of genetically based adaptation during the process of becoming invasive is very scant, however, which is due to the lack of knowledge regarding the historical genetic makeup of the introduced populations and the lack of genomic resources. Capitalizing on the availability of old non-native herbarium specimens, we examined frequency shifts in genic SNPs of the Pyrenean Rocket (Sisymbrium austriacum subsp. chrysanthum), comparing the (i) native, (ii) currently spreading non-native and (iii) historically introduced gene pool. Results show strong divergence in flowering time genes during the establishment phase, indicating that rapid genetic adaptation preceded the spread of this species and possibly assisted in overcoming environmental constraints.

“…Environmental conditions differ to a greater extent between populations than between individuals in separate populations. Higher differences between populations according to the amount of polymorphic DNA loci might reflect bigger differences in site features [15][16][17][18]. For I. glandulifera, studied by us in parallel, genetic differentiation between populations was much smaller (Φ PT =0.51) [32].…”

“…Reviewed by Cross et al [17] and Dormontt et al [18], populations of various alien species might be distinguished by amplified fragment length polymorphism (AFLP) [19][20][21], by random amplified polymorphic DNA (RAPD) [22][23][24], by microsatellite/simple sequence repeat (SSR) [25][26][27][28][29] and by inter simple sequence repeat (ISSR) [24,30] loci. Among Balsaminaceae, the biggest variety of molecular markers, including nuclear microsatellites [25,31], chloroplast microsatellites [25] and RAPD [32] were applied to Impatiens glandulifera.…”

Climatic shifts within recent decades created favorable conditions for invasive species flourishing in more Northern parts of Europe. Our study was aimed at evaluation of genetic variability and habitat features of Impatiens parviflora populations growing in Lithuania. Twenty one populations were selected and analysed using simple sequence repeat (SSR) and randomly amplified polymorphic DNA (RAPD) assays. Evaluated by SSRs, 315 individuals were all monomorphic and homozygous at 4 loci and heterozygous at 1 locus. RAPD analyses revealed that the percentage of polymorphic DNA loci (% P) per population ranged from 7 to 39% and genetic differentiation between populations was ΦPT=0.790 (P<0.01). Genetic distances among populations (0.135–0.426) correlated significantly with geographical distances (r=0.183; P<0.008). Populations in overmoistured soil contained higher % P (28.3) when compared to drier soil (18.7; P<0.05). All recorded populations were close to roads; their % P did not depend on proximity to buildings, light intensity or population size. Our RAPD analyses indicate multiple introductions of this species in Lithuania. Analyses of I. parviflora at SSR and RAPD loci show that the invasion process is reflected in genetic structure.

“…Some studies, however, provide evidence that reduced genetic diversity is not always the rule for non-native populations, and that genetic diversity can be maintained by different mechanisms dependent on introduction history (multiple vs. single introductions), native range genetic structure and propagule pressure (Petit et al 2004; Prentis et al 2008; Le Roux et al 2011; Mandák et al 2013). For example, inter- or intraspecific hybridization can lead to similar or increased diversity levels compared with source populations and can generate gene combinations which might be better adapted or more tolerant to novel environmental conditions (Ellstrand and Schierenbeck 2000; Dormontt et al 2011). …”

We compared the seedling growth performance of native and non-native Siberian elm populations in a common greenhouse experiment to gain knowledge about possible changes in life history traits in populations of non-native woody species. Our results showed that non-native Siberian elm populations are characterized by an enhanced early life cycle performance which likely contributes to its invasion success. This study contributes to a better understanding of the still little-known invasion processes of woody non-native species.
