Metagenomic methods provide an experimental approach to inform the relationships between hosts and their microbial inhabitants. [] Key Method The variables ranged from those considered to have ancient and long-term influences (host phylogeny and life history) to the relatively transient variable of host reproductive condition. In addition, collection locality data, representing the geographic variable, were included in analyses. Results indicate a complex influence of variables in shaping sample…

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

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.

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

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.

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

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.

Adapting to novel environments together: evolutionary and ecological correlates of the bacterial microbiome of the world’s largest cavefish diversification

The largest diversification of cavefishes of the world, Sinocyclocheilus, not only shows that habitat, and phylogenetic clade is important in determining their gut microbiome, but also that they reach a common microbiome in captivity irrespective of their phylogenetic position, region of origin and habitat, indicating that they are adaptable in the context of microbe related changes in their environment.

An introduction to phylosymbiosis

The relevant literature and data in the last decade are reviewed, emphasizing frequently used methods and regular patterns observed in analyses, and opportunities ripe for investigation from a diversity of disciplines are outlined.

Bighorn sheep gut microbiomes associate with genetic and spatial structure across a metapopulation

The results imply that microbiome composition may diverge in accordance with landscape-scale environmental and host population characteristics, and potentially associated with genetic and geographic population structure.

The role of biogeography in shaping diversity of the intestinal microbiota in house mice

Geography was found to be the most significant factor explaining patterns of diversity in the intestinal microbiota, with a comparatively weaker influence of host population structure and genetic distance.

Adapting to Novel Environments Together: Evolutionary and Ecological Correlates of the Bacterial Microbiome of the World’s Largest Cavefish Diversification (Cyprinidae, Sinocyclocheilus)

The results suggest that divergent natural environments giving rise to evolutionary novelties underlying host adaptations, also includes the microbiome of these fishes.

Microbial communities exhibit host species distinguishability and phylosymbiosis along the length of the gastrointestinal tract

Gut microbial communities were highly distinguishable by host species across all gut regions, with the strength of the discrimination increasing along the length of the gut, and the pattern of phylosymbiosis was found in all five Gut regions, as well as faeces.

Microbiome evolution along divergent branches of the vertebrate tree of life: what is known and unknown

The state of microbiome studies of nonmammalian vertebrates are reviewed and a synthesis of emerging patterns in the microbiome of those organisms is provided, highlighting the importance of collection methods, and the need for greater taxonomic sampling of natural rather than captive hosts.



Global patterns in the biogeography of bacterial taxa.

Bacteria control major nutrient cycles and directly influence plant, animal and human health. However, we know relatively little about the forces shaping their large-scale ecological ranges. Here, we

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

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.

UniFrac: a New Phylogenetic Method for Comparing Microbial Communities

The results illustrate that UniFrac provides a new way of characterizing microbial communities, using the wealth of environmental rRNA sequences, and allows quantitative insight into the factors that underlie the distribution of lineages among environments.

A Molecular Phylogeny for Bats Illuminates Biogeography and the Fossil Record

The results support the hypothesis that megabats are nested among four major microbat lineages, which originated in the early Eocene, coincident with a significant global rise in temperature, increase in plant diversity and abundance, and the zenith of Tertiary insect diversity.

When did plants become important to leaf‐nosed bats? Diversification of feeding habits in the family Phyllostomidae

It is proposed that during the evolution of phyllostomids switches to new feeding mechanisms to access to abundant and/or underexploited resources provided selective advantages that favoured the appearance of ecological innovations independently in different lineages of the family.

Evolutionary History of Bats: Molecular time scale of diversification of feeding strategy and morphology in New World Leaf-Nosed Bats (Phyllostomidae): a phylogenetic perspective

Specializations in feeding specialization among phyllostomids are remarkable when viewed in the context of the concomitant suite of adaptations associated with the sensory apparatus, locomotion, digestion, dentition, kidney function, and reproduction.


Among phyllostomids additional examples of feeding specialization exist, including subsisting exclusively on insects, as well as primarily on fruit, nectar, frogs, rodents, and other vertebrates.

Evolution of Mammals and Their Gut Microbes

It is indicated that host diet and phylogeny both influence bacterial diversity, which increases from carnivory to omnivory to herbivory; that bacterial communities codiversified with their hosts; and that the gut microbiota of humans living a modern life-style is typical of omnivorous primates.
