Invasive species are non-native organisms that establish self-sustaining populations and spread beyond their initial introduction sites, causing or likely to cause significant ecological, economic, or health impacts. Research on invasive species examines pathways of introduction, propagule pressure, life-history traits that facilitate invasion (e.g., high reproductive rate, broad ecological tolerance), and interactions with native communities, including competition, predation, hybridization, and pathogen transmission. The topic also encompasses invasion stages (transport, introduction, establishment, spread), invasion ecology theory (e.g., enemy release, biotic resistance), risk assessment, and management strategies such as prevention, early detection, rapid response, and long-term control or eradication.
The removal of invasive rodents from Lord Howe Island has triggered a rebound of invertebrate life, with researchers from the University of Sydney and collaborators documenting sharp increases in the abundance of insects ...

Biological invasions occur when organisms such as animals and plants are introduced by people to regions of the world where they do not naturally occur. In these new locations, these organisms are referred to as "alien species."
