demonstrated in the Comoros Archipelago , in the Pacific  and globally . It has been hypothesised that low-latitude tropical reefs bleached less than those in higher latitudes because:  of the geographical differences in species composition,  of the higher genotypic diversity at low latitudes, and  some corals were pre-adapted to thermal stress because of consistently warmer temperatures at low latitude prior to thermal stress events . However, latitudinal variation was not reported in other global surveys of coral bleaching occurrence . Ainsworth et al.  and Ateweberhan et al.  showed that coral bleaching can be mitigated by pre- exposure to elevated temperatures. Regionally, recovery is also highly variable. While some reefs in the Seychelles and Maldives were shown to recover to pre-disturbance levels of coral cover after previous bleaching events , other reefs underwent seemingly permanent regime shifts toward domination by fleshy macro algae , or major declines in carbonate budgets, and thus the capacity of reefs to sustain vertical growth under rising sea levels .
