"PeerJ Preprints" is a venue for early communication or feedback before peer review. Data may be preliminary.

Supplemental Information

Exclusive bacterial species

OTUs showing differential abundances between yellow (HC) and blue (HF) abalone with statistical and biological significance obtained from LEfSe analyses. OTUs are ranked according to its effect size (LDA score).

DOI: 10.7287/peerj.preprints.3233v1/supp-1

Taxonomic comparison

Non-parametric multidimensional scaling (MDS) of Sorensen similarity index based on presence and absence of OTUs assembled at 97% similarity cut-off of the gut microbiota of Haliotis fulgens (HF) and H. corrugata (HC).

DOI: 10.7287/peerj.preprints.3233v1/supp-2

Genetic groups interactions

Regression of the average Jaccard distance based on phylogenetic groups of bacterial OTUs (10% similarity) as a function of their abundance –log scale – (HF: Haliotis fulgens, HC: Haliotis corrugata).

DOI: 10.7287/peerj.preprints.3233v1/supp-3

PICRUSt correction

Ranks of the KO genes according to their KO count number (log scale) obtained with the script categorize by function in PICRUSt.

DOI: 10.7287/peerj.preprints.3233v1/supp-4

Classified OTUs assignement

Reads number for each detected OTU.

DOI: 10.7287/peerj.preprints.3233v1/supp-5

PICRUSt identified KOs genes

Count number for each identified gene

DOI: 10.7287/peerj.preprints.3233v1/supp-6

PICRUSt identified metabolic functions

Count number for each identified metabolic function.

DOI: 10.7287/peerj.preprints.3233v1/supp-7

Bacterial species competitive pressures

Average value of Jaccard distance for each OTU detected in yellow (HC) and blue abalone (HF).

DOI: 10.7287/peerj.preprints.3233v1/supp-8
