However, other introduced species are able to reproduce and proliferate rapidly, due either to taking over an empty ecological niche, a lack of competing native species or an absence of predators in their new environment. }] ‘Urbanization as a major cause of biotic homogenization’, Biological Conservation, 127: 247–60.
