This quantity explores a lot of those concerns for the 1st time.

Parthenogenesis has been reported to facilitate the success of the invaders (Simberloff, 1989; Niemelä and Mattson, 1996 and references therein) but this does not seem to account for adaptation to tree resistance. On the other hand, polyploidy and heterozygosity, which also favor invasions because of conferring broader ecological amplitude to the invader (Bullini & Nascetti, 1990; Niemelä & Mattson, 1996), can be important for a quick adaptation to tree resistance.
