“…Functionally, Actinobacteria was regard to participate in the decomposition of organic matter in soil and sediments, and studies in mammals have shown a positive correlation with fiber intake (Henning et al 2017). While some carp species (Li et al 2018b), birds (Sun et al 2018) and mammals (Gu et al 2013;Andersson et al 2008) shared Bacteroidetes as the most common phylum (relative abundance > 10%), Firmicutes (mostly the genus of Tyzzerella 3 in this work) was found with relative abundance evenly distributed among the detected samples.…”

Increasing evidences suggest that intestinal microbiota balance closely correlated with host's health status could affected by external environment. Integrated crayfish-rice cultivation model is a highly efficient artificial ecosystem widely practiced in subtropical China. Less information is available to estimate the influence response to the micro-ecology of crayfish intestine and so as to influence the biological processes. Thus, 16S rRNA high-throughput sequencing approach was employed to investigate the composition diversity and functions of bacterial community in the intestines of Procambarus clarkii farmed within this model. Results exhibited the highly diversity of microflora with dominant phyla Actinobacteria, Proteobacteria, Tenericutes, Firmicutes and Bacteroidetes. The genera of Candidatus Bacilloplasma and Ornithinibacter were presented as predominant population much exceeds in richness comparing to that of other genus. Despite the highly diversity in the bacterial community, the predicted functions indicated relative consistent in biological processing pathway. Collectively, significant richness of genes was observed involved in amino acid and carbohydrate metabolism and membrane transport processing. This study would contribute to the understanding of the impact of growth conditions on host-microbiota relation especially in aquatic animals.

“…The taxonomic composition of blue tit fecal bacterial microbiota was dominated by Actinobacteria, Proteobacteria, and Firmicutes. Proteobacteria and Firmicutes have been previously reported to dominate bird fecal microbiota [68][69][70]. Interestingly, we found that Actinobacteria were very abundant in bird feces, but this group was not typically dominant in bird fecal microbiota in other studies.…”

Bacterial microbiota similarity between predators and prey in a blue tit trophic network

Trophic networks are composed of many organisms hosting microbiota that interact with their hosts and with each other. Yet, our knowledge of the factors driving variation in microbiota and their interactions in wild communities is limited. To investigate the relation among host microbiota across a trophic network, we studied the bacterial microbiota of two species of primary producers (downy and holm oaks), a primary consumer (caterpillars), and a secondary consumer (blue tits) at nine sites in Corsica. To quantify bacterial microbiota, we amplified 16S rRNA gene sequences in blue tit feces, caterpillars, and leaf samples. Our results showed that hosts from adjacent trophic levels had a more similar bacterial microbiota than hosts separated by two trophic levels. Our results also revealed a difference between bacterial microbiota present on the two oak species, and among leaves from different sites. The main drivers of bacterial microbiota variation within each trophic level differed across spatial scales, and sharing the same tree or nest box increased similarity in bacterial microbiota for caterpillars and blue tits. This study quantifies host microbiota interactions across a three-level trophic network and illustrates how the factors shaping bacterial microbiota composition vary among different hosts.

“…OTUs accounting for less than 0.001% of total sequences across all samples were discarded. To minimize the difference of sequencing depths across samples, an average, rounded rarefied OTU table was generated by averaging 100 evenly resampled OTU subsets under the 90% of the minimum sequencing depth for further analysis (Liu et al, 2019; Sun et al, 2019).…”

Père David’s deer (Elaphurus davidianus or milu) is a highly endangered species originating from China, and many deer are currently being raised in captivity for gradual re-introduction to the wild. Wild and captive deer currently live in the same region but have vastly different diets. In this study, we used 16S rRNA high-throughput sequencing to identify the healthy core microbiome in the gut of wild and captive Père David’s deer and investigate how dietary factors influence the gut microbiome by comparing their differences. A core shared gut microbiome was identified in healthy Père David’s deer, which was similar to that of other ruminants, mainly comprising the phyla Firmicutes and Bacteroidetes. There were no differences in the richness or diversity of the gut microbiome between the wild and captive deer. However, PCA and ANOSIM demonstrated clear differences in the microbial community structure between the captive and wild deer, which mainly manifested as changes in the relative abundance of 39 bacterial genera. As the majority of these genera were not dominant in the deer gut, no significant difference was detected in functional modules related to the microbiome between the two groups. Therefore, the difference in dietary factors does not appear to affect the healthy core gut microbiome between captive and wild Père David’s deer, suggesting strong co-evolution and the possibility of re-establishment in the wild. These data could guide future applications of population management in Père David’s deer conservation.
