Species introduced deliberately or inadvertently by humans to areas outside their native ranges affect native species in many ways. Some impacts, such as predation and herbivory, are obvious, but others are subtle and may result from complex, sometimes indirect interactions of more than two species. No habitat or area is immune to impacts of introduced species, but some sorts of sites, such as anthropogenically disturbed areas and oceanic islands, are particularly prone to invasions. Arrival of a new invader may lead to evolution by both the invader and native species with which it interacts.
