  abstract = {{A}im {B}iogeographical processes underlying {I}ndo-{P}acific biodiversity patterns have been relatively well studied in marine shallow water invertebrates and fishes, but have been explored much less extensively in seaweeds, despite these organisms often displaying markedly different patterns. {U}sing the marine red alga {P}ortieria as a model, we aim to gain understanding of the evolutionary processes generating seaweed biogeographical patterns. {O}ur results will be evaluated and compared with known patterns and processes in animals. {L}ocation {I}ndo-{P}acific marine region. {M}ethods {S}pecies diversity estimates were inferred using {DNA}-based species delimitation methods. {H}istorical biogeographical patterns were inferred based on a six-gene time-calibrated phylogeny, distribution data of 802 specimens, and probabilistic modelling of geographical range evolution. {T}he importance of geographical isolation for speciation was further evaluated by population genetic analyses at the intraspecific level. {R}esults {W}e delimited 92 candidate species, most with restricted distributions, suggesting low dispersal capacity. {H}ighest species diversity was found in the {I}ndo-{M}alay {A}rchipelago ({IMA}). {O}ur phylogeny indicates that {P}ortieria originated during the late {C}retaceous in the area that is now the {C}entral {I}ndo-{P}acific. {T}he biogeographical history of {P}ortieria includes repeated dispersal events to peripheral regions, followed by long-term persistence and diversification of lineages within those regions, and limited dispersal back to the {IMA}. {M}ain conclusions {O}ur results suggest that the long geological history of the {IMA} played an important role in shaping {P}ortieria diversity. {H}igh species richness in the {IMA} resulted from a combination of speciation at small spatial scales, possibly as a result of increased regional habitat diversity from the {E}ocene onwards, and species accumulation via dispersal and/or island integration through tectonic movement. {O}ur results are consistent with the biodiversity feedback model, in which biodiversity hotspots act as both "centres of origin" and "centres of accumulation," and corroborate previous findings for invertebrates and fish that there is no single unifying model explaining the biological diversity within the {IMA}.},
