Scientific Publication in Marine Biology

An international team of researchers including Dr. Vanessa Bednarz, postdoctoral researcher in the Ecophysiology team of the Centre Scientifique de Monaco, recently published a series of three studies that describe the coral reef status in the Spermonde Archipelago, Indonesia.

The Spermonde Archipelago is a complex of ~70 mostly populated islands off Southwest Sulawesi, Indonesia, in the center of the Coral Triangle, the world area where coral-specific richness is the highest. The reefs in this area are exposed to a high level of anthropogenic disturbances. In the three studies, water quality parameters, benthic community structure, fish assemblages and trophic niches of herbivorous fish species were investigated annually from 2012 to 2014 at eight different islands of the archipelago, varying in distance from 1 to 55 km relative to the mainland.

Generally, the coral reef status gradually increased from onshore to offshore. Besides the heavy environmental pressures in the study area, common in the greater Southeast Asian region, some islands appeared relatively more resilient to disturbance than others. The main environmental drivers of coral reef status in the Spermonde Archipelago are presented and a selected number of water quality, benthic and fish indices is being recommend as an integral part of future reef monitoring.
