Coral reefs are impacted worldwide by coastal eutrophication, which is often translated a decrease in coral cover and an increase potentially harmful invertebrates algal blooms. Additionally to corals other macro-benthos, micro-benthic communities affected tremendously, however few studies reported the specific effect of eutrophication on those communities. This study addresses how turbidity associated eutrophication. To answer this question, we compared three groups that have been previously suggested as bioindicators reef environmental conditions: foraminifera, diatoms bacteria, from 12 islands (and 600 samples) Spermonde Archipelago (Indonesia) along near- offshore gradient. Insights DNA metabarcoding satellite images highlighted differences between slope (deep) flat (shallow) communities, distinction has omitted most previous studies. The were 1.5- 2-fold more parameters slope, argue related Based work, expected prokaryotes would be group water quality. However, found large benthic foraminifera diatom highly turbidity, whereas prokaryotic primarily shaped substrate type. Additionally, total 112 exact sequence variants (ESVs) identified indicators different levels, 87 ESVs with high-moderate turbid waters. Our revealed fundamental knowledge provides key information habitat variables (substrate type area) We local regional participates shaping may therefore play important role early warning signals for degradation reefs.
