Abstract(s)
Studies on microbial communities are pivotal to understand the role and the evolutionary paths of the
host and their associated microorganisms in the ecosystems. Meta-genomics techniques have proven
to be one of the most efective tools in the identifcation of endosymbiotic communities of host
species. The microbiome of the highly exploited topshell Phorcus sauciatus was characterized in the
Northeastern Atlantic (Portugal, Madeira, Selvagens, Canaries and Azores). Alpha diversity analysis
based on observed OTUs showed signifcant diferences among regions. The Principal Coordinates
Analysis of beta-diversity based on presence/absence showed three well diferentiated groups, one
from Azores, a second from Madeira and the third one for mainland Portugal, Selvagens and the
Canaries. The microbiome results may be mainly explained by large-scale oceanographic processes
of the study region, i.e., the North Atlantic Subtropical Gyre, and specifcally by the Canary Current.
Our results suggest the feasibility of microbiome as a model study to unravel biogeographic and
evolutionary processes in marine species with high dispersive potential.
