“…This has primarily been considered in relation to whether an introduced plant is a close relative of (e.g. in the same genus as) a native species (Branco, Brockerhoff, Castagneyrol, Orazio, & Jactel, ; Burghardt & Tallamy, ; Kirichenko & Kenis, ; Salisbury et al, , ), but phylogenetic distinctiveness (our proxy for the novelty of a new plant habitat) is more complex than a binary congeneric/noncongeneric classification. When quantified as a phylogenetic isolation (Mya), phylogenetic distinctiveness can affect the diversity of insects on both native (Vialatte et al, ) and introduced plants (Grandez‐Rios, Bergamini, Santos de Araújo, Villalobos, & Almeida‐Neto, ) by influencing their phenotype.…”
