Microbiomes of the Arctic carnivorous sponges Chondrocladia grandis and Cladorhiza oxeata suggest a specific, but differential involvement of bacterial associates
While sponges are generally known to host a wide range of microbial associates, the composition and specificity of the microbial communities in carnivorous sponges are poorly understood. We used 16S rRNA gene data to examine and compare the bacterial communities associated with distinct anatomical r...

While sponges are generally known to host a wide range of microbial associates, the composition and specificity of the microbial communities in carnivorous sponges are poorly understood.

The two sponge species hosted distinct bacterial communities, with taxonomic diversity being greater in C. grandis. Some bacterial taxa (including particular oligotypes) were consistently recovered in multiple host individuals from geographically distant sites, suggesting specificity.
