Contemporary ecological heterogeneity shapes candidate adaptive genomic variation across the native range of an invasive herbivore
Ecological heterogeneity within a species’ native range can shape genomic variation available for subsequent range expansion and biological invasion. The cactus moth, Cactoblastis cactorum, is a South American oligophagous herbivore on Opuntia that has become an invasive pest outside its native range. In Argentina, pop...
