  abstract = {{S}tudying genetic connectivity in marine populations aims to understand the dispersal of an organism through the seascape and thus its gene flow. {H}ere, we focused on one lineage of the recently revised coral {P}ocillopora damicornis complex, {P}. damicornis type beta, corresponding to {P}rimary {S}pecies {H}ypothesis {PSH}05 in {G}elin et al. ({M}ol {E}col 19:430-446, 2017b): it had been hypothesized that {P}. damicornis type beta encompasses four distinct lineages, representing {S}econdary {S}pecies {H}ypotheses ({SSH}05a, {SSH}05b, {SSH}05c and {SSH}05d). {T}he aim of the present study was to confirm this partition and to infer the genetic structuring and connectivity among 27 populations for this widespread and common scleractinian. {F}or this, a total of 1418 colonies were hierarchically sampled from two marine provinces of the southern parts of its distribution range, which remain largely understudied: the {W}estern {I}ndian {O}cean and the {T}ropical {S}outhwestern {P}acific. {U}sing 13 microsatellite loci and assignment tests, our findings confirmed the partition into four {SSH}s, each {SSH} splitting into clusters, suggesting that {P}. damicornis beta type may represent a complex of cryptic species. {M}oreover, within each {SSH}, clonal propagation was evidenced in almost every population, but clonal dispersal was mostly restricted to sampling site (except in {R}eunion {I}sland and northern {M}adagascar, where clones were found in several populations approximately 50 km apart). {N}evertheless, wherever the cursor of species level is placed (one or several species), populations were highly differentiated both within the {W}estern {I}ndian {O}cean and the {T}ropical {S}outhwestern {P}acific, suggesting restricted gene flow at different spatial scales (marine province, ecoregions, islands/regions), leading to diverging lineages.},
