In the Mediterranean Sea, the zooxanthellate coral Oculina patagonica (Scleractinia, Oculinidae) can turn algal forests into coral-dominated ecosystems and provides a case study for examining how zooxanthellate corals can affect the structure of algal-dominated shallow-water rocky ecosystems in temperate areas. Our goal was to provide a quantitative baseline assessment of O. patagonica demographics along ~1300 km of the Mediterranean Iberian coast and relate them to environmental parameters. The highest coral success was in the South Balearic Sea zone, where the populations exhibited N6-fold higher mean living coral cover, lower partial colonymortality and colony size distributions indicating that the populations in this zone were growing faster than those in the peripheral south-west (North Alborán Sea) and north-east (Mid and North Balearic Sea, and West Gulf of Lyons) zones. The coral demographics (i.e., density, cover, and skewness and kurtosis coefficients of colony size distributions) were positively correlated with each other and the annual mean seawater temperature (ST), 10th-ST percentile (P10th-ST), 90th-ST percentile (P90th-ST) and photosynthetically active radiation at 3-m depth (PAR-3m), but they were negatively correlated with chlorophyll-a. Based on these results, we identified the following thresholds that may constrain the growth of O. patagonica colonies and populations: annual mean ST b19–20 °C, P10th-ST b14 °C, P90th-ST b25 °C and N27 °C, and PAR-3m b30 mol photons m−2 day−1. The species abundance along the Iberian coast conforms to the abundant-center pattern of distribution. However, the coral demographics indicated that this pattern was not only related to the time of establishment but also to differences in coral population growth, which were correlated with key environmental parameters. Our results contribute understanding of the forces driving population growth of O. patagonica and support the hypothesis of an ongoing coral-mediated tropicalization of macroalgae-dominated temperate ecosystems.Financial support was provided by project CSI-CORAL (CGL2013-43106- R) of the Spanish Government.
