Conclusion
In this study, we describe the occurrence of long-distance jump dispersal in the native range of the termite R. flavipes . This long-distance dispersal may allow admixture between populations that are otherwise isolated. Similar to multiple introductions through different pathways, admixture in native populations prior to introduction may favor invasion success by increasing the amount of genetic diversity brought to the introduced range. However, pre-introduction admixture may not be as common as multiple introduction scenarios (i.e.,post-introduction admixture), because the benefits of admixture in the novel environment of the invasive range are probably higher, and the costs smaller. As native populations are locally adapted, long-distance dispersal and admixture therefore disturb this local adaptation (Verhoeven et al. 2011, Palacio-Lopez et al. 2017). In contrast, populations in invaded ranges are too recent to be locally adapted. This lack of local adaptation releases introduced populations from maintaining specific locale-selected allelic combinations, and therefore allows them to fully benefit from admixture.
