“…In the present study, Chloro exi were the most abundant overall bacterial phylum and were only rare in species from the high light intensity pools or adjacent coral reef habitat, namely, the phototrophic species or S. carteri, a known LMA sponge species. A number of studies have found Chloro exi members to be particularly abundant in HMA species (Schmitt et Cleary et al 2020Cleary et al , 2021. Although Chloro exi members are absent or rare in many LMA species, they can be abundant in others.…”

In the present study, we describe elements of the sponge fauna sampled from unique pool-cave-canyon systems at a remote island off the southeastern coast of Taiwan. 22 demosponge species are described of which 10 are new to science, and possibly endemic. Prokaryotic communities were obtained from all species in addition to sediment. What makes the present study unique is that we were able to sample several understudied sponge taxa, e.g., sclerosponges and lithistids, across a relatively small spatial scale. We present the first prokaryotic community analysis of 10 species new to science in addition to Vetulina incrustans, Sollasipelta ornata, Petrosia corticata, Acanthostylotella cornuta, several lithistid species, two phototrophic sponges, and the sclerosponges Acanthochaetetes wellsi, and Astrosclera willeyana. All cave sponges were enriched with SAR202 members, a group of bacteria involved in the degradation of recalcitrant compounds. We suggest that the cave sponges may play a hitherto unexplored role in nutrient dynamics at the land-sea interface. We also encourage surveys of potentially similar systems in Japan and the Philippines. The sponges sampled here also are only a fraction of the total sponge fauna. When surveyed the system appeared to be in good health. Potential threats include large groups of tourists visiting the pools and the presence of a nuclear waste storage facility directly abutting the largest of the pool-cave-canyon systems.

We attribute this to the apparent power law relationship between host dissimilitude and prokaryotic dissimilarity.In contrast to space and host dissimilitude, the purely environmental component only explained a very small amount of variation in composition, 0.3%.…”

The impact of space, host dissimilitude and environment on prokaryotic communities of golf ball sponges

Golf ball sponges are small, sometimes inconspicuous, sponges. They can be found across a range of habitats varying from perturbed and pristine coral reefs to harbours and marine lakes and from the deep sea to shallow waters. They can be difficult to distinguish in the field and have presented some problems with taxonomists lumping and splitting species due to the difficulty in defining clear species traits. In the present study, we sampled golf ball sponges from Indo-Pacific and Caribbean locations and used 16S gene amplicon sequencing to study their prokaryotic communities. We show that golf ball sponges harbour a wide variety of prokaryotic communities. Among the most prevalent operational taxonomic units (OTUs), several belonged to a range of taxa, including AqS1 and ED94, which have been associated with genes known to facilitate interactions between hosts and microbes. Certain host taxa were enriched with OTUs assigned to the SAR202 clade of Chloroflexi. Our findings show that prokaryotic dissimilarity varied as a function of space (geographical distance) and host dissimilitude. The importance of space and host dissimilitude, however, varied depending on the data transformation with host dissimilitude a more important predictor of untransformed data whereas space was a more important predictor of log-transformed data. Given that log-transformation down scales the influence of abundant taxa, we interpret these results by the tendency of closely related host organisms to host similar abundant symbiotic microorganisms whereas specimens that are distantly sampled tend to harbour less abundant prokaryotic microorganisms that mirror the characteristics of their distant environments.

The amount of available light plays a key role in the growth and development of microbial communities. In the present study, we tested to what extent sponge-associated prokaryotic communities differed between specimens of the sponge species Cinachyrella kuekenthali and Xestospongia muta collected in dimly lit (caves and at greater depths) versus illuminated (shallow water) habitats. In addition to this, we also collected samples of water, sediment, and another species of Cinachyrella, C. alloclada. Overall, the biotope (sponge host species, sediment, and seawater) proved the major driver of variation in prokaryotic community composition. The light habitat, however, also proved a predictor of compositional variation in prokaryotic communities of both C. kuekenthali and X. muta. We used an exploratory technique based on machine learning to identify features (classes, orders, and OTUs), which distinguished X. muta specimens sampled in dimly lit versus illuminated habitat. We found that the classes Alphaproteobacteria and Rhodothermia and orders Puniceispirillales, Rhodospirillales, Rhodobacterales, and Thalassobaculales were associated with specimens from illuminated, i.e., shallow water habitat, while the classes Dehalococcoidia, Spirochaetia, Entotheonellia, Nitrospiria, Schekmanbacteria, and Poribacteria, and orders Sneathiellales and Actinomarinales were associated with specimens sampled from dimly lit habitat. There was, however, considerable variation within the different light habitats highlighting the importance of other factors in structuring sponge-associated bacterial communities.
