Over the past decades, human impacts have changed structure of tropical benthic reef communities towards coral depletion and macroalgal proliferation. However, how these changes modified chemical microbial waterscapes is poorly known. Here, we assessed experimental removal assemblages influences composition two boundary layers, momentum. Chemical were spatially structured, both horizontally vertically, according to dominance layers. Microbes associated with degradation enriched in layers surrounding macroalgal-dominated substrata. Dominant macroalgae surrounded by a distinct pool diverse lipid classes (e.g., diterpenoids glycerolipids) labile organic matter organooxygen compounds), which diffused from algal tissues their polarity. Finally, our results highlighted strong co-variations between specific algal-derived metabolites planktonic microbes, giving insight into roles functioning resilience.
