Correlation between gut microbiota and host phylogeny could reflect codiversification over shared evolutionary history or a selective environment that is more similar in related hosts. These alternatives imply substantial differences in the relationship between host and symbiont, but can they be distinguished based on patterns in the community data themselves? We explored patterns of phylogenetic correlation in the distribution of gut bacteria among species of turtle ants (genus Cephalotes… 

Phylosymbiosis: Relationships and Functional Effects of Microbial Communities across Host Evolutionary History

TLDR
Findings indicate that the composition and functional effects of an animal's microbial community can be closely allied with host evolution, even across wide-ranging timescales and diverse animal systems reared under controlled conditions.

Divergence of Fecal Microbiota and Their Associations With Host Phylogeny in Cervinae

TLDR
Correlation was observed between the fecal microbiota divergence and host phylogeny, but they were not congruent completely, which may shed new light on the coevolution of host species and their microbiota.

Terrestriality and bacterial transfer: a comparative study of gut microbiomes in sympatric Malagasy mammals

TLDR
It is found that diet—reliance on leaves versus fruit—is the best predictor of microbiome similarity among closely related lemur species, and that host substrate use—ground versus tree—constrains horizontal transmission via incidental contact with feces, with arboreal species harboring far more distinct communities than those of their terrestrial and semi-terrestrial counterparts.

Gut microbiota may predict host divergence time during Glires evolution.

TLDR
The results suggest the gut microbial composition is associated with host phylogeny, and further suggest that dissimilarity of animal gut microbiota may predict host divergence time.

Correlates of gut community composition across an ant species (Cephalotes varians) elucidate causes and consequences of symbiotic variability

TLDR
This study used 454 pyrosequencing and TRFLP to achieve goals in an herbivorous ant, Cephalotes varians, exploring variation in bacterial communities across colonies, populations and workers reared on different diets, and found core species were dominated by 16 core species present in over two‐thirds of the sampled colonies.

Ecology and Host Identity Outweigh Evolutionary History in Shaping the Bat Microbiome

TLDR
It is concluded that the gut, oral, and skin microbiota of bats are shaped predominantly by ecological factors and do not exhibit the same degree of phylosymbiosis observed in other mammals.

Limited Evidence for Microbial Transmission in the Phylosymbiosis between Hawaiian Spiders and Their Microbiota

TLDR
Home (host-microbiota evolution), a cophylogenetic model designed to detect vertically transmitted microbes and host switches from amplicon sequencing data, is applied to the microbiotas of Hawaiian spiders of the genus Ariamnes, which display a clear phylosymbiosis pattern and is found that none of the bacterial operational taxonomic units is vertically transmitted.

Deep divergence and rapid evolutionary rates in gut-associated Acetobacteraceae of ants

TLDR
Patterns in Camponotus-associated Acetobacteraceae resemble those found in cospeciating gut associates that are both socially and maternally transmitted, and suggest that these associates may represent an intermediate point along an evolutionary trajectory manifest most extremely in symbionts with strict maternal transmission.

Significant effects of host dietary guild and phylogeny in wild lemur gut microbiomes

TLDR
It is concluded that GM diversity is predominantly shaped by host phylogeny, and that microbes associated with diet were likely acquired before evolutionary radiations within the lemur families examined.

Gut Microbiota in Decapod Shrimps: Evidence of Phylosymbiosis.

TLDR
Observations of a parallelism in the taxonomy of the gut microbiota with host phylogeny for all shrimp groups examined and in the predicted functions for the penaeid shrimps indicate a tight host-microbial relationship during evolution.

Factors associated with the diversification of the gut microbial communities within chimpanzees from Gombe National Park

TLDR
Despite the broad similarity of community members, long-term immigrants to a community often harbored the most distinctive gut microbiota, suggesting that individuals retain hallmarks of their previous gut microbial communities for extended periods.

Do diet and taxonomy influence insect gut bacterial communities?

TLDR
Evidence is found to support the hypotheses that host diet and taxonomy structure insect gut bacterial communities (P < 0.001) were important in hymenopteran and termite gut community structure, and diet was an important community structuring factor particularly for insect hosts that ingest lignocellulose‐derived substances.

Highly similar microbial communities are shared among related and trophically similar ant species

TLDR
Similar microbial communities are harbored by ants from similar trophic niches and, to a greater extent, by related ants from the same colonies, species, genera, and tribes, suggesting new possibilities for roles of bacteria in the evolution of both herbivores and carnivores from the ant family Formicidae.

A simple and distinctive microbiota associated with honey bees and bumble bees

TLDR
It is found that most bee species lack phylotypes that are the same or similar to those typical of A. mellifera, rejecting the hypothesis that this dietary transition was symbiont‐dependent and potentially key to the maintenance of a more consistent gut microbiota.

Bacterial gut symbionts are tightly linked with the evolution of herbivory in ants

TLDR
The hypothesis that bacteria have facilitated convergent evolution of herbivory across the ants is supported, further implicating symbiosis as a major force in ant evolution.

Diet Drives Convergence in Gut Microbiome Functions Across Mammalian Phylogeny and Within Humans

TLDR
The value of characterizing vertebrate gut microbiomes to understand host evolutionary histories at a supraorganismal level is illustrated by shotgun sequencing of microbial community DNA and targeted sequencing of bacterial 16S ribosomal RNA genes.

Convergence of gut microbiomes in myrmecophagous mammals

TLDR
It is confirmed that both diet and phylogeny drive the evolution of mammalian gut microbiota, with cases of convergence in global composition, but also examples of phylogenetic inertia.

Surveying the Microbiome of Ants: Comparing 454 Pyrosequencing with Traditional Methods To Uncover Bacterial Diversity

TLDR
It is found that gut tissues had significantly higher diversity than nongut tissues, and many of the OTUs identified from these groups clustered within ant-specific lineages, indicating a deep coevolutionary history of Cephalotes ants and their associated microbes.

Species divergence and the measurement of microbial diversity.

TLDR
Divergence-based methods are providing new insights into microbial community structure and function because microorganisms in a community differ dramatically in sequence similarity, which also often correlates with phenotypic similarity in key features such as metabolic capabilities.
