N2 - Understanding patterns of community structure and the causes for their 82 variation can be furthered by comparative biogeographic analyses of island biotas. We 83 used local scale woody plant data to investigate within- and between-island variations in 84 species rarity and alpha, beta and gamma diversity in islands from three oceanic 85 archipelagoes. We used standardized protocols to sample ten 50 m × 50 m forest plots in 86 each of three islands with contrasting climate and regional species pools: Terceira 87 (Azores), Tenerife (Canaries), and Reunion (Mascarene Islands). Occupancy frequency 88 distributions and species abundance distributions were used to investigate rarity. The 89 partitioning of beta diversity in a distance-decay framework was used to test for spatial 90 patterns of community composition. Rarity was much more pronounced in the highly 91 diverse islands of Tenerife and Reunion than in the regionally poorer island of Terceira. 92 The number of species rose faster with increasing sample area in both Tenerife and 93 Reunion. The slope of the species rank abundance curve was steeper in Terceira, 94 whereas the richer island assemblages approached a lognormal model. Compositional 95 changes according to spatial distance were mostly due to replacement of species in 96 Terceira and Reunion. Our results point to important differences in the community 97 structure of the regionally less diverse temperate island (Terceira) versus the two 98 regionally highly diverse islands (Tenerife and Reunion).
