AB Understanding patterns of community structure and thecauses for their variation can be furthered by comparative biogeographicanalyses of island biotas. We used woody plant data at the local scale toinvestigate variations in species rarity, alpha, beta, and gamma diversitywithin and between three islands from the oceanic archipelagoes ofAzores, Canaries and Mascarene. We used standardized protocols tosample ten 50 m × 50 m forest plots in each of the three islands withcontrasting climate and regional species pools: Terceira (Azores),Tenerife (Canaries), and Reunion (Mascarene Islands). Occupancyfrequency distributions and species abundance distributions wereused to investigate rarity. The partitioning of beta diversity in adistance-decay framework was used to test for spatial patterns ofcommunity composition. Rarity was much more pronounced in thehighly diverse islands of Tenerife and Reunion than in the regionallypoorer island of Terceira. The number of species rose faster withincreasing sample area in both Tenerife and Reunion. The slope ofthe species rank abundance curve was steeper in Terceira whereasthe richer island assemblages approached a lognormal model.Compositional changes according to spatial distance were mostlydue to replacement of species in Terceira and Reunion. Our resultspoint to important differences in the community structure of Terceira,which is the less diverse and temperate region in comparison toTenerife and Reunion which are highly diverse.
