Comparative Study of the Gut Microbiota Among Four Different Marine Mammals in an Aquarium
Despite an increasing appreciation in the importance of host–microbe interactions in ecological and evolutionary processes, information on the gut microbial communities of some marine mammals is still lacking. Moreover, whether diet, environment, or host phylogeny has the greatest impact on microbia...
