title: Does the legacy of historical biogeography shape current invasiveness in pines?
abstract: Why are some introduced species more successful at establishing and spreading than others? Until now, characteristics of extant species have been intensively investigated to answer this question. We propose to gain new insights on species invasiveness by exploring the long-term biogeographic and evolutionary history of lineages. We exemplify our approach using one of the best-studied invasive plant genera, Pinus. We notably estimated the historical biogeography of pines and the rates of trait evolution in pines. These estimates were analysed with regard to species invasiveness status. The results revealed that currently invasive species belong to lineages that were particularly successful at colonizing new regions in the past. We also showed that highly mobile lineages had faster rates of niche evolution, but that these rates are poor proxies for species adaptive potential in invaded regions (estimated by niche shift among native and invaded regions). In summary, working at the interface of ecology, historical biogeography and evolutionary history offers stimulating perspectives to improve our understanding of the drivers of invasion success.
