“…Also, the high growth rates of farmed explants could be linked to the overall stability of the core taxa, both indicating a steady fitness of the holobiont. These findings are in agreement with previous studies analyzing sponge-associated core microbiomes, either in tropical regions (Campana et al 2021b ; Leal et al 2022 ), temperate waters (Lamb and Watts 2023 ) or polar ecosystems (Happel et al 2022 ), suggesting that changing environmental conditions might have a relatively low impact in the shaping of the core sponge microbiome. The 18 core ASVs identified belong to 13 genera mostly affiliated to Acidobacteriota, Chloroflexi, PAUC34f and Proteobacteria.…”

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 confirmed a spatial specificity amongst samples at different longitudinal scales. Results from this additional spatial analysis confirmed that differences in prokaryotic communities might first be explained by environmental changes (mainly temperature and salinity), while no significant effect 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 influence of sponge translocation during in situ aquaculture.

“…Contrastingly, in heat stressed A. cavernosa, we observed an increase in members of several bacterial families (Clostridiaceae, Flavobacteriaceae, Rhodobacteraceae) and two genera (Ruegeria and Winogradskyella). Genus Clostridium (family Clostridiaceae, Firmicutes) can be found in healthy Xestospongia muta specimens (Leal et al, 2022), and order Clostridiales in Leucetta chagosensis after experimental exposition to "present day" seawater temperature and pH conditions (Posadas et al, 2021). Moreover, class Clostridia was more abundant in diseased than in healthy corals (reviewed in Mouchka et al, 2010).…”

How does heat stress affect sponge microbiomes? Structure and resilience of microbial communities of marine sponges from different habitats

et al. 2023

IntroductionSponges are key components of marine benthic communities, providing many ecosystem functions and establishing close relationships with microorganisms, conforming the holobiont. These symbiotic microbiotas seem to be host species-specific and highly diverse, playing key roles in their sponge host. The effects of elevated seawater temperature on sponges and their microbiota are still poorly known, and whether sponges from polar areas are more sensitive to these impacts respect to temperate and tropical species is totally unknown.MethodsWe analyzed the microbiomes of different sponge species in their natural habitat and after exposure to heat stress in aquaria by 16S rRNA amplicon sequencing to (1) characterize the sponge microbiota covering a latitudinal gradient (polar, temperate and tropical environments), and (2) asses the effects of thermal stress on their microbial communities.ResultsBacterial communities’ structure was different in the different sponge species and also respect the surrounding seawater. The core microbiome is maintained in most sponge species after a heat stress, although whether they would recover to the normal conditions previous to the stress remains yet to be further investigated. We observed increased abundances of transient bacteria from unknown origin in sponge species exposed to heat stress.DiscussionSome of the transient bacteria may be opportunistic bacteria that may benefit from the heat stress-associated dysregulation in the sponge by occupying new niches in the holobiont. According to our results, sponges from Antarctic waters could be more resilient than tropical and temperate sponges. Both the microbiome composition and the changes produced by the heat stress seem to be quite host species-specific, and thus, depend on the sponge species. Under a global change scenario, the microbiomes of the tropical and temperate sponges will probably be those suffering the most the heat stress, and therefore the effects of global change may be dramatic for benthic ecosystems since sponges are a fundamental part of them.
