 note = {Leucaena leucocephala is an invasive alien plant species in subtropical and tropical Pacific islands. Our previous research showed that biological invasion by this plant species had a serious effect on secondary succession on Haha-jima Island, a subtropical oceanic island. Here, we reconstruct the pattern of secondary succession related to Leucaena leucocephala invasion on Miyako-jima Island, another subtropical continental island, to examine the hypothetical negative relationship between diversity and susceptibility to Leucaena leucocephala invasion. Although Leucaena leucocephala scrub was established immediately following agricultural abandonment, it was replaced within a few decades by a local forest type, dominated by Macaranga tanarius and Melanolepis multiglandulosa, fast-growing secondary-forest trees found in tropical regions. The dominance of Machilus thunbergii and Cinnamomum japonicum, which dominated the native primary forests on Miyako-jima Island, gradually increased as secondary succession progressed, and 35-40 years after abandonment, the species composition of the late-successional secondary forests resembled that of the resident mature secondary forest. This pattern of secondary succession shows that the biological invasion of Leucaena leucocephala had less affect on Miyako-jima Island than Haha-jima Island. The results in this study therefore provide evidence for the hypothesis that simple communities on oceanic islands are more susceptible than diverse communities on continental islands to biological invasion by Leucaena leucocephala.},
