Reef-building corals are cornerstones of life in the oceans. Understanding
their interactions with microorganisms and their surrounding physicochemical
conditions is important to comprehend reef functioning and ultimately
protect coral reef ecosystems. Corals associate with a complex and specific
array of microorganisms that supposedly affect their physiology and
therefore can significantly determine the condition of a coral ecosystem. As
environmental conditions may shape bacterial diversity and ecology in the
coral symbiosis, ecosystem changes might have unfavorable consequences
for the holobiont, to date poorly understood.
Here, we were studying microbial community changes in A. hemprichii as a
consequence of simulated eutrophication and overfishing over a period of
16 weeks by using in situ caging and slow release fertilizer treatments in an
undisturbed Red Sea reef (22.18ºN, 38.57ºW). We used 16S rDNA amplicon
sequencing to evaluate the individual and combined effects of overnutrification
and fishing pressure, two of the most common local threats to
coral reefs.
With our data we hope to better understand bacterial population dynamics
under anthropogenic influences and its role in coral resilience. Projecting
further, this data will be useful to better predict the consequences of human
activity on reef ecosystems.
