BackgroundDarwin’s finches are a clade of 19 species of passerine birds native to the Galápagos Islands, whose biogeography, specialized beak morphologies, and dietary choices—ranging from seeds to blood—make them a classic example of adaptive radiation. While these iconic birds have been intensely studied, the composition of their gut microbiome and the factors influencing it, including host species, diet, and biogeography, has not yet been explored.ResultsWe characterized the microbial… 
An inter-island comparison of Darwin’s finches reveals the impact of habitat, host phylogeny, and island on the gut microbiome
TLDR
Together, these results corroborate the influence of phylogeny, age, diet, and sampling location on microbiome composition and emphasize the necessity for comprehensive sampling given the multiple factors that influence the gut microbiome in Darwin’s finches, and by extension, in animals broadly.
Host phylogeny, diet, and habitat differentiate the gut microbiomes of Darwin’s finches on Santa Cruz Island
TLDR
The gut microbiome in Darwin’s finches is characterized, showing moderate congruence with the microbiome, which was comprised mostly of the bacterial phyla Firmicutes, Actinobacteria, and Proteobacteria.
Human activity can influence the gut microbiota of Darwin's finches in the Galapagos Islands
TLDR
The results show that the gut microbiota of Darwin's finches is affected differently across sites with varying human presence, and gut bacterial community structure differed across sites and host species.
Phylogeography and Ecological Niche Shape the Cichlid Fish Gut Microbiota in Central American and African Lakes
TLDR
A partial congruency was found between host microbiota and genetic distances, suggesting that microbial communities have partly diversified along their cichlid phylogeographic history of crater lakes, suggesting the level of habitat segregation, trophic niche overlap, and reproductive barriers as major modulators of the gut microbiota connectivity among sympatric species.
Gut microbiota in two recently diverged passerine species: evaluating the effects of species identity, habitat use and geographic distance
TLDR
The results suggest that neither habitat use, nor geographical distance, nor species identity have strong influence on the nightingale Gut microbiota composition, which suggests that changes in the gut microbiota composition are unlikely to contribute to reproductive isolation in these passerine birds.
The Gut Microbial Composition Is Species-Specific and Individual-Specific in Two Species of Estrildid Finches, the Bengalese Finch and the Zebra Finch
TLDR
This study conclusively shows that host-specific factors contribute structuring of gut microbiota, and that within-individual variation in microbial communities was larger in males of both species.
Macrobdella decora: Old World Leech Gut Microbial Community Structure Conserved in a New World Leech
TLDR
The similarity of the microbial community structure of species from two different continents reveals the highly-conserved nature of the bacterial symbionts in sanguivorous leeches and confirms the medicinal leech as a highly simplified, natural animal model in which to study gut symbioses.
Characterization of the gut microbiome of black-necked cranes (Grus nigricollis) in six wintering areas in China
TLDR
The gut microbial community compositions, diversity, and functions of black-necked cranes from six wintering areas in China using the Illumina Miseq platform are characterized, providing a baseline for further microbiological studies and a foundation for the conservation of this bird.
Comparison of Gut Microbiota between Gentoo and Adélie Penguins Breeding Sympatrically on Antarctic Ardley Island as Revealed by Fecal DNA Sequencing
TLDR
The results suggested that both the phylogeny of penguin species and the diet could be responsible for the differences in the gut microbiota of the two pygoscelid penguins breeding in the same area.
Gut microbiome is affected by inter-sexual and inter-seasonal variation in diet for thick-billed murres (Uria lomvia)
TLDR
The observed variation in the gut microbiome of the thick-billed murre may be caused by individual prey specialization and may also be reinforced by sexual and reproductive stage differences in diet.

Baleen whales host a unique gut microbiome with similarities to both carnivores and herbivores
TLDR
It is demonstrated that functional attributes of the microbiome can vary independently even given an animal-derived diet, illustrating how diet and evolutionary history combine to shape microbial diversity in the mammalian gut.
Evolution of Darwin’s finches and their beaks revealed by genome sequencing
TLDR
The whole-genome re-sequencing of 120 individuals representing all of the Darwin’s finch species and two close relatives finds extensive evidence for interspecific gene flow throughout the radiation.
Gut Microbiota Dynamics during Dietary Shift in Eastern African Cichlid Fishes
TLDR
This study surveys the host intra- and interspecific natural variation of the gut microbiota of five cichlid species from the monophyletic tribe Perissodini of lake Tanganyika, whose members transitioned from being zooplanktivorous to feeding primarily on fish scales, and suggests that, with increased host phylogenetic distance and/or increasing herbivory, the Gut microbiota begins differentiating also at qualitative level.
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.
Host‐specific associations affect the microbiome of Philornis downsi, an introduced parasite to the Galápagos Islands
TLDR
The results suggest that the microbiome of P. downsi changes during its development, according to dietary composition or nutritional needs, and is significantly affected by host‐related factors during the larval stage, which will contribute to the development of novel, effective control strategies.
The bottlenose dolphin (Tursiops truncatus) faecal microbiota.
TLDR
Dolphins possess a unique microbiota profile within the Mammalia class, highly resembling that of carnivorous marine fishes, and the breast-fed calf showed a distinctive compositional structure of the gut microbial ecosystem, which partially overlaps with the mother's milk microbiota.

TLDR
The giant panda appears not to have evolved a gut microbiota compatible with its newly adopted diet, which may adversely influence the coevolutionary fitness of this herbivore.

TLDR
This study used quantitative real‐time polymerase chain reaction (qPCR) and 16S rRNA gene pyrosequencing to characterize the interspecific variations of the GI microbiota of four penguin species: the king, gentoo, macaroni, and little penguin.

Evidence for previously unrecognized host-microbiome associations along the gastrointestinal tract from the American alligator is provided, a crown archosaur with shared ancestry to extinct taxa, including dinosaurs.
