STATUS OF CORAL REEFS IN SRI LANKA: A MICROBIAL PERSPECTIVE

ABSTRACT :

Coral reefs have suffered from a range of impacts from local anthropogenic influence to global climate change. In recent years these impacts have led to changes in coral community structures from coral reefs dominated by living corals to dominance by algae (which is called phase-shift). These changes affect the overall trophic structure of reefs. We hypothesize that the microbial community in the water column in a coral reef could be an indicator to explain the status of coral reefs. Present coral reef monitoring was conducted at 6 reef sites around Sri Lanka from February 2014 to January 2015. Results show that the coral reefs in north are dominated by living corals whereas reefs in south dominated by algae. Microbial abundance and inorganic nutrients concentrations are also consistence with the observed benthic status. Further studies are in progress to explain the status of coral reef in a microbial perspective.
