“…The species investigated were the known LMA sponges: Jaspis splendens ( Js ) (order Tetractinellida), Stylissa carteri ( Sc ) , and Stylissa massa ( Sm ) (order Scopalinida), and the known HMA sponges: Hyrtios erectus ( He ) (family Thorectidae, order Dictyoceratida) and Xestospongia testudinaria ( Xt ) (family Petrosiidae, order Haplosclerida). All of these species are widespread species and have been observed from the Western Indian Ocean to the Pacific Ocean (Cleary et al, ; Coelho et al, ; Swierts et al, ). In addition, four species were investigated of which the HMA/LMA status was unknown: Ectyoplasia coccinea ( Ec ) (family Raspailiidae, order Axinellida), Liosina paradoxa ( Lp ) (family Dictyonellidae, order Bubarida), Paratetilla bacca ( Pb ) (family Tetillidae, order Tetractinellida), and Petrosia aff.…”

Marine sponges are known to host diverse and abundant communities of microbial symbionts. It has been generally assumed that the bacterial communities of low microbial abundance (LMA) sponges are less diverse than those of high microbial abundance (HMA) sponges. In this study, we used next‐generation sequencing technology to explore the bacterial communities of several biotopes including sponges, seawater, and sediment from the remote Western Indian Ocean island of Mayotte. The species investigated were the known LMA sponges: Jaspis splendens, Stylissa carteri, and Stylissa massa, and the known HMA sponges: Hyrtios erectus and Xestospongia testudinaria. In addition to this, we also investigated the following sponge species: Ectyoplasia coccinea, Paratetilla bacca, Liosina paradoxa, and Petrosia aff. spheroida of which the exact HMA/LMA status is unknown although we preliminarily classified them as HMA or LMA based on the status of closely related species. Certain HMA sponges shared similar bacterial communities dominated by Actinobacteria and Chloroflexi, whereas another species (E. coccinea) had a bacterial community closer to that of LMA sponges. Most LMA sponges housed a bacteriome dominated by Proteobacteria and Cyanobacteria, but the bacteriome of P. bacca also included dominant Chloroflexi and actinobacterial OTUs. Together with S. carteri, this sponge housed a more diverse bacterial community at the phylum, class, and order levels than HMA sponges. Although certain LMA sponges housed a bacterial community similar to the surrounding environment (seawater), they also included highly abundant, possibly species or genus specific, OTUs. Based on this study and small set of sponges studied, we conclude that a clear dichotomy between HMA and LMA sponges does not appear to exist.

“…Giant barrel sponges are a particularly suitable model for such research since they have a broad distribution on coral reefs around the globe and have an intricate phylogeny (Swierts et al . 2013 , 2017 ). While three giant barrel sponge species have been described so far, namely Xestospongia muta from the Caribbean, Xestospongia testudinaria from the Indo-Pacific and Xestospongia bergquistia from the northeastern coast of Australia, molecular studies comparing these giant barrel sponge species were unable to find a separation that correlated with the species descriptions as they exist today (Setiawan et al .…”

Sponges harbor complex communities of microorganisms that carry out essential roles for the functioning and survival of their hosts. In some cases, genetically related sponges from different geographic regions share microbes, while in other cases microbial communities are more similar in unrelated sponges collected from the same location. To better understand how geography and host phylogeny cause variation in the prokaryotic community of sponges, we compared the prokaryotic community of 44 giant barrel sponges (Xestospongia spp.). These sponges belonged to six reproductively isolated genetic groups from eight areas throughout the Indo-Pacific region. Using Illumina sequencing, we obtained 440 000 sequences of the 16S rRNA gene V3V4 variable region that were assigned to 3795 operational taxonomic units (OTUs). The prokaryotic community of giant barrel sponges was characterized by 71 core OTUs (i.e. OTUs present in each specimen) that represented 57.5% of the total number of sequences. The relative abundance of these core OTUs varied significantly among samples, and this variation was predominantly related to the geographic origin of the sample. These results show that in giant barrel sponges, the variation in the prokaryotic community is primarily associated with geography as opposed to phylogenetic relatedness.

Sponges occur across diverse marine biomes and host internal microbial communities that can provide critical ecological functions. While strong patterns of host specificity have been observed consistently in sponge microbiomes, the precise ecological relationships between hosts and their symbiotic microbial communities remain to be fully delineated. In the current study, we investigate the relative roles of host population genetics and biogeography in structuring the microbial communities hosted by the excavating sponge Cliona delitrix. A total of 53 samples, previously used to demarcate the population genetic structure of C. delitrix, were selected from two locations in the Caribbean Sea and from eight locations across the reefs of Florida and the Bahamas. Microbial community diversity and composition were measured using Illumina‐based high‐throughput sequencing of the 16S rRNA V4 region and related to host population structure and geographic distribution. Most operational taxonomic units (OTUs) specific to Cliona delitrix microbiomes were rare, while other OTUs were shared with congeneric hosts. Across a large regional scale (>1,000 km), geographic distance was associated with considerable variability of the sponge microbiome, suggesting a distance–decay relationship, but little impact over smaller spatial scales (<300 km) was observed. Host population structure had a moderate effect on the structure of these microbial communities, regardless of geographic distance. These results support the interplay between geographic, environmental, and host factors as forces determining the community structure of microbiomes associated with C. delitrix. Moreover, these data suggest that the mechanisms of host regulation can be observed at the population genetic scale, prior to the onset of speciation.
