Phenotypic and genetic differentiation between native and introduced plant populations (2005, background): “range, but all introduced European populations are tetraploid (Lafuma et al. 2003).”
Ploidy influences rarity and invasiveness in plants (2011, background): “In this large-scale analysis, we were also unable to consider situations in which, for example, a species is diploid in much of its native range, but polyploid as an invasive in non-native ranges (Lafuma et al. 2003; Treier et al. 2009).”
Hyper-specialization for long-billed bird pollination in a guild of South African plants: the Malachite Sunbird pollination syndrome (2009, methodology): “55, frequency distributions are taken to be bimodal (Lafuma et al., 2003).”
The “Polyploid Hop”: Shifting Challenges and Opportunities Over the Evolutionary Lifespan of Genome Duplications (2018, background): “polyploids do in the invasive ranges (Lafuma et al., 2003; Mandák et al., 2005; Kubátová et al., 2007; Schlaepfer et al., 2008; Treier et al., 2009) suggest a potential pre-adaptation of polyploids for invasiveness (te Beest et al.”
The more the better? The role of polyploidy in facilitating plant invasions. (2012, background): “A pan-European, crosstaxa assessment.”
Evidence for a combination of pre‐adapted traits and rapid adaptive change in the invasive plant Centaurea stoebe (2010, background): “…indicate that interspecific variation in ploidy level in species is associated with invasiveness (Pyšek et al. 2009a) and that within species, polyploids rather than diploids are the dominant invasive forms (Lafuma et al. 2003; Pandit, Tan & Bisht 2006; Schlaepfer et al. 2008; Treier et al. 2009).”
Selection of preadapted populations allowed Senecio inaequidens to invade Central Europe (2008, background): “In contrast, all European populations tested were tetraploid (Lafuma et al., 2003), which also suggests that invasive European populations originate from the mountain regions of southern Africa.”
