Reproductive biology of key habitat-forming cold-water corals in the Azores Archipelago
In the Azores, gorgonians and antipatharians are the most frequent habitat-builders, making up more than twenty different types of the so called “coral gardens” that are found between 20 and 3,500 m depth. Despite their importance as ecosystem engineers, there is no information about their basic bio...
