  abstract = {{I}slands in the tropical {P}acific {O}cean are renowned for high biodiversity and endemism despite having relatively small landmasses. {H}owever, our knowledge of how this biodiversity is formed remains limited. {T}he taxon cycle, where well-dispersed, earlier colonizers become displaced from coastal to inland habitats by new waves of colonizers, producing isolated, range-restricted species, has been proposed to explain current biodiversity patterns. {H}ere, we integrate the outcomes of phylogenetic studies in the region to investigate the sources, age, number of colonizations, and diversification of 16 archipelagos in the tropical and subtropical {S}outh {P}acific. {W}e then evaluate whether the results support the taxon cycle as a plausible mechanism for these observations. {W}e find that most species in the {P}acific arrived less than 5 {M}ya from geographically close sources, suggesting that colonization by new taxa is a frequent and ongoing process. {T}herefore, our findings are broadly consistent with the theory of the {T}axon {C}ycle, which posits that ongoing colonization results in the gradual displacement of established lineages. {O}nly the oldest archipelagos, {N}ew {C}aledonia and {F}iji, do not conform to this trend, having proportionally less recent colonization events, suggesting that the taxon cycle may slow on older islands. {T}his conclusion is further validated by {N}ew {C}aledonia having lower diversification rate estimates than younger islands. {W}e found that diversification rates across archipelagos are negatively correlated with area and age. {T}herefore, a taxon cycle that slows with island age appears to be a suitable concept for understanding the dynamic nature and biodiversity patterns of the {P}acific {I}slands.},
