Slow progression of black band disease in Goniopora cf. columna colonies may promote its persistence in a coral community

Coral diseases have been little investigated in the Indian Ocean and especially in the Republic of Maldives, where they were firstly observed in 2010. Through repeated monitoring, we observed a peculiar slow progression of Black Band Disease in several large colonies of the reef-building coral Goniopora cf. columna in the Maldivian reefs of Magoodhoo Island (Faafu Atoll). We argue that this may ensure the local persistence of the disease, possibly promoting long-term mortality of other, more susceptible coral species.
