Population genetic structure of the Pocillopora damicornis morphospecies along Ningaloo Reef, Western Australia

Research on the coral species Pocillopora damicornis along Ningaloo Reef, Western Australia, reveals two genetically distinct lineages with high dispersal potential and partial reproductive barriers. Despite significant genetic differentiation, low levels of unidirectional admixture indicate that these lineages are not fully isolated. Both lineages exhibit dual reproduction modes, with sexual reproduction contributing variably across sites. The most common lineage shows strong spatial autocorrelation up to 60 km, suggesting high resilience to patchy disturbances. This study highlights the importance of genetic structure in understanding coral recovery and management strategies for UNESCO World Heritage Sites like Ningaloo Coast.
