Abstract: Aggressive invaders can compete strongly in direct conflicts with each other and with ecologically similar native species. Non-aggressive invasive species that avoid conflict, but are also highly competitive are much less common in the literature. We revealed the absence of aggression in the highly successful invasive Asian house gecko in direct encounters with both conspecifics, and with an ecologically similar, aggressive native Australian house gecko.
