Description:
Dynamics of microbiomes through time
are fundamental regarding survival and resilience of
their hosts when facing environmental alterations.
As for marine species with commercial applications, such as marine sponges, assessing the temporal
change of prokaryotic communities allows us to better consider the adaptation of sponges to aquaculture
designs. The present study aims to investigate the
factors shaping the microbiome of the sponge Dactylospongia metachromia, in a context of aquaculture
development in French Polynesia, Rangiroa, Tuamotu
archipelago. A temporal approach targeting explants
collected during farming trials revealed a relative
high stability of the prokaryotic diversity, meanwhile
a complementary biogeographical study confrmed a
spatial specifcity amongst samples at diferent longitudinal scales. Results from this additional spatial
analysis confrmed that diferences in prokaryotic
communities might frst be explained by environmental changes (mainly temperature and salinity),
while no signifcant efect of the host phylogeny was
observed. The core community of D. metachromia
is thus characterized by a high spatiotemporal constancy, which is a good prospect for the sustainable
exploitation of this species towards drug development. Indeed, a microbiome stability across locations
and throughout the farming process, as evidenced by our results, should go against a negative infuence of
sponge translocation during in situ aquaculture.
