The impacts of biological invasions
Biological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological
