We compared the Caribbean reef sponge, Axinella corrugata, with the Caribbean reef coral, Erythropodium caribaeorum for differences in their resident microbial communities. This cursory survey of bacterial diversity applied 16S rRNA gene sequences. Over 100 culture-independent sequences were generated from five different Axinella 16S rRNA libraries, and compared with 69 cultured isolates. The cultureindependent 16S rDNA clones displayed a higher diversity of Proteobacteria, including “uncultured” or “unknown” representatives from the Deltaproteobacteria. Arcobacterium, and Cyanobacteria were also found. We have also confirmed that Axinella sponges appeared to host specific microbial symbionts, similar to the previously identified clones termed “OSO” …

Mitochondrial 16S ribosomal RNA was used to elucidate the pattern of relationships and systematic status of 4 genera, including 9 species of skates (Rostroraja alba, Leucoraja fullonica, Dipturus oxyrinchus, D. batis, Raja clavata, R. montagui, R. asterias, R. miraletus, and R. radula), living in the Mediterranean and Black Seas. The 16S rDNA dataset contained 39 variable and 29 parsimony informative sites. The mean nucleotide diversity (Pi) was 0.018. The genetic distances between pairs of species showed genetic homogeneity between R. clavata and R. montagui. The highest value of sequence divergence was detected between D. oxyrinchus and R. asterias (0.040). Low …
