Host Species Determines Symbiotic Community Composition in Antarctic Sponges (Porifera: Demospongiae)
The microbiota of four Antarctic sponges, Dendrilla antarctica, Sphaerotylus antarcticus, Mycale acerata, and Hemigellius pilosus, collected at two South Shetland Islands and at two locations in the Antarctic Peninsula separated by ca. 670 km, were analyzed together with surrounding seawater. We use...

Our study reveals that sponge-associated prokaryote communities are consistently detected within a particular sponge species regardless of the collection site.

We conclude that prokaryote communities from Antarctic sponges are less diverse and differ in their composition compared to those in the water column.
