Microbial response to simulated global change is phylogenetically conserved and linked with functional potential. Gut Microbiome is an open access journal, co-published by Cambridge University Press and The Nutrition Society, with the aim of supporting the development of an integrated, interdisciplinary understanding of the gut microbiome. Sampling the water of a saltwater aquarium allows for detection of specific beneficial microbes . The coral core microbiome identifies rare bacterial taxa as ubiquitous endosymbionts. (2015).

Applied together, they have the potential to reveal different layers of microbial organization from which we can begin to understand the ecological and evolutionary processes that govern host-microbe interactions. CCA was performed between the matrix of the first 30 microbial (OTU table) principal component scores and host genotype principal component scores based on a common SNP. These groups are found in samples from subjects of several races, in those consuming both Eastern and Western diets, in both sexes, and in a variety of subject ages ( (Aguirre de Carcer 2018 ).
