Title

Algal Endosymbiont Diversity in the Common Reef-Building Coral Goniastrea Ten Years after Experimental Bleaching

Presentation Type

Event

Description/Abstract

Symbiotic dinoflagellates (Symbiodinium) have a mutualistic symbiosis with many coral species because both partners receive benefit via the exchange of nutrients. The successful interaction of these partners determines the success of coral reefs. Ten colonies of Goniastrea spp. were collected from inshore and offshore reefs surrounding Ofu Island, American Samoa in 2006 (n=20 total). The corals were experimentally bleached and, then reciprocally transplanted to each environment, to determine how Symbiodinium community structure and diversity recovers and changes with time. In 2016, DNA was extracted and three diagnostic molecular markers were amplified using PCR to investigate the diversity of Symbiodinium within each coral sample.
