Taxonomically different symbiotic communities of sympatric Arctic sponge species show functional similarity with specialization at species level

In this study, bacterial communities associated with three species of cold-water marine sponges (Isodictya palmata, Halichondria panicea, and Halichondria sitiens) and surrounding seawater from the White and Barents Seas were studied by 16S and shot-gun metagenomics.
