Microbiome of the Southwestern Atlantic invasive scleractinian coral, Tubastraea tagusensis
Abstract Background Commonly known as sun-coral, Tubastraea tagusensis is an azooxanthellate scleractinian coral that successfully invaded the Southwestern Atlantic causing significant seascape changes. Today it is reported to over 3500 km along the Brazilian coast, with several rocky shores display...
