“…These findings are consistent with a general pattern emerging from literature reviews indicating that invasive plants perform better in their introduced compared to their native range (Hinz and Schwarzlaender 2004;Bossdorf et al 2005;Parker et al 2013). In our study, the populations surveyed in North America experienced higher mean and lower maximum temperatures than those in Europe, but differences in performance of L. vulgare between ranges remained significant even after we corrected for differences in these two climatic variables.…”

“…Comparative studies assessing performance of invasive alien plant species under field conditions revealed that they often perform better in their introduced than in their native ranges (Hinz and Schwarzlaender 2004;Parker et al 2013). One of the most prominent hypotheses explaining their increased size and abundance in their introduced range is the enemy release hypothesis (Keane and Crawley 2002;Colautti et al 2004).…”

Can enemy release explain the invasion success of the diploid Leucanthemum vulgare in North America?

Enemy release is a commonly accepted mechanism to explain plant invasions. Both the diploid Leucanthemum vulgare and the morphologically very similar tetraploid Leucanthemum ircutianum have been introduced into North America. To verify which species is more prevalent in North America we sampled 98 Leucanthemum populations and determined their ploidy level. Although polyploidy has repeatedly been proposed to be associated with increased invasiveness in plants, only two of the populations surveyed in North America were the tetraploid L. ircutianum. We tested the enemy release hypothesis by first comparing 20 populations of L. vulgare and 27 populations of L. ircutianum in their native range in Europe, and then comparing the European L. vulgare populations with 31 L. vulgare populations sampled in North America. Characteristics of the site and associated vegetation, plant performance and invertebrate herbivory were recorded. In Europe, plant height and density of the two species were similar but L. vulgare produced more flower heads than L. ircutianum. Leucanthemum vulgare in North America was 17 % taller, produced twice as many flower heads and grew much denser compared to L. vulgare in Europe. Attack rates by root-and leaf-feeding herbivores on L. vulgare in Europe (34 and 75 %) was comparable to that on L. ircutianum (26 and 71 %) but higher than that on L. vulgare in North America (10 and 3 %). However, herbivore load and leaf damage were low in Europe. Cover and height of the co-occurring vegetation was higher in L. vulgare populations in the native than in the introduced range, suggesting that a shift in plant competition may more easily explain the invasion success of L. vulgare than escape from herbivory.

“…We have previously reported that Spodoptera grow better on plants from Europe; 22 our current results reveal that this difference is due exclusively to better growth on tetraploid plants. However, our results also show that both diploids and tetraploids from the US were poor hosts for Spodoptera: diploids because they caused high mortality and tetraploids in the introduced range, 12,15,16 few of these studies have also examined the influence of cytotype. 17 Three cytotypes of S. gigantea can be found in its native range in North America (diploid, tetraploid and hexaploid, 2n = 18, 36 and 54 respectively).…”

Herbivores are sensitive to the genetic structure of plant populations, as genetics underlies plant phenotype and host quality. Polyploidy is a widespread feature of angiosperm genomes, yet few studies have examined how polyploidy influences herbivores. Introduction to new ranges, with consequent changes in selective regimes, can lead to evolution of changes in plant defensive characteristics and also affect herbivores. Here, we examine how insect herbivores respond to polyploidy in Solidago gigantea, using plants derived from both the native range (USA) and introduced range (Europe). S. gigantea has three cytotypes in the US, with two of these present in Europe. We performed bioassays with generalist (Spodoptera exigua) and specialist (Trirhabda virgata) leaf-feeding insects. Insects were reared on detached leaves (Spodoptera) or potted host plants (Trirhabda) and mortality and mass were measured. Trirhabda larvae showed little variation in survival or pupal mass attributable to either cytotype or plant origin. Spodoptera larvae were more sensitive to both cytotype and plant origin: they grew best on European tetraploids and poorly on US diploids (high mortality) and US tetraploids (low larval mass). These results show that both cytotype and plant origin influence insect herbivores, but that generalist and specialist insects may respond differently.Polyploidy, or the possession of more than two sets of homologous chromosomes, is a fundamental force in angiosperm evolution.

“…In the absence of specialists, plants may experience selection to increase production of certain volatile compounds that attract not only herbivores but also mutualists such as pollinators (35)(36)(37). Enhanced reproductive success of invasive species in areas of invasion, although attributed to greater competitiveness or ''vigor'' (38), may also result from increased production of volatile compounds mediating interactions with pollinating mutualists. Such responses could account for seemingly paradoxical findings of enhanced production of certain ''defense'' chemicals in areas of invasion; these defense chemicals may serve other ecological roles.…”
