  abstract = {{S}pecies abundance distributions ({SAD}s) characterise the distribution of individuals among species. {SAD}s have rarely been explored on islands and the ecological processes shaping {SAD}s are still not fully understood. {N}otably, the relative importance of disturbance regime in shaping plant {SAD}s remains poorly known. {W}e investigate the relative importance of disturbance regime and island geography on the shape of {SAD}s. {W}e computed {SAD}s for local tree communities in 1-ha forest plots on 20 tropical islands in the {I}ndo-{P}acific region. {W}e used generalized linear models to analyse how the shape parameter of the gambin {SAD} model was related to the number of trees and the number of species. {R}egression analyses were also used to investigate how the shape of {SAD}s, the number of trees and the number of species were related to cyclone disturbance (power dissipation index) and geography (island area and isolation), with direct and indirect (i.e. through the number of trees and species) effects assessed using variance partitioning. {C}yclone disturbance was the best predictor of the shape of {SAD}s, with higher power dissipation index producing more lognormal-like distributions. {T}his effect was mostly due to cyclones increasing the number of trees and decreasing the number of species. {I}sland area affected the shape of {SAD}s through its effect on the number of species, and larger islands were associated with higher species richness and more logseries-like distributions. {T}he effect of cyclones was stronger on smaller islands. {O}ur results illustrate that disturbances can affect {SAD}s in complex ways; directly and indirectly by impacting the number of species and individuals in communities, and these effects may be moderated by island-specific characteristics, such as island area or isolation. {O}ur results therefore suggest that multiple, interacting processes shape {SAD}s and that studying {SAD}s has the potential to contribute important new insights to the field of island biogeography.},
