Invasion facilitates hybridization with introgression in the Rattus rattus species complex
Abstract Biological invasions result in novel species interactions, which can have significant evolutionary impacts on both native and invading taxa. One evolutionary concern with invasions is hybridization among lineages that were previously isolated, but make secondary contact in their invaded ran...
