Herbivore range expansion triggers adaptation in a subsequently-associated third trophic level species and shared microbial symbionts

Abstract Invasive species may change the life history strategies, distribution, genetic configuration and trophic interactions of native species. The diamondback moth, Plutella xylostella L., is an invasive herbivore attacking cultivated and wild brassica plants worldwide. Here we present phylogeogr...
