Global meta‐analysis reveals the drivers of gut microbiome variation across vertebrates

open access: yesiMetaOmics, Volume 1, Issue 2, December 2024.
This study analyzed 6508 16S rRNA gene sequence data from 113 vertebrate species worldwide and evaluated the effects of host diet and habitat climate on the diversity of the vertebrate gut microbiome. The results showed that diet and climate factors significantly affected changes in the gut microbiome.

Neisseria weixii sp. nov., isolated from rectal contents of Tibetan Plateau pika (Ochotona curzoniae)

open access: yesInternational Journal of Systematic and Evolutionary Microbiology, 2019
Three independent isolates (10022T, 10 009 and 10011) of a novel catalase-positive, Gram-stain-negative coccus in the genus Neisseria were obtained from the rectal contents of plateau pika on the Qinghai-Tibet Plateau, PR China. Based on 16S rRNA gene sequence analysis, our newly identified organisms were most closely related to Neisseria iguanae ...

Multitrophic Diversity of the Biotic Community Drives Ecosystem Multifunctionality in Alpine Grasslands

open access: yesEcology and Evolution, Volume 14, Issue 11, November 2024.
Our results indicated that primary producers, primary consumers, and soil decomposers were crucial trophic groups for maintaining ecosystem functionality, collectively driving changes in ecosystem multifunctionality. Additionally, abiotic factors such as altitude and pH influenced ecosystem multifunctionality.

Diet diversity is associated with beta but not alpha diversity of pika gut microbiota

open access: yesFrontiers in Microbiology, 2016
Wild mammals often consume different food sources as they become geographical available. This change in diet composition is likely to influence the gut microbial community, yet it remains unclear what the relationship looks like—particularly in small ...

Enterotypes of the Gut Microbial Community and Their Response to Plant Secondary Compounds in Plateau Pikas

open access: yesMicroorganisms, 2020
Animal gut microbiomes can be clustered into “enterotypes” characterized by an abundance of signature genera. The characteristic determinants, stability, and resilience of these community clusters remain poorly understood.

Diet of Andean Leaf‐Eared Mice (Phyllotis) Living at Extreme Elevations on Atacama Volcanoes: Insights From Metagenomics, DNA Metabarcoding, and Stable Isotopes

open access: yesEcology and Evolution, Volume 14, Issue 11, November 2024.
On the flanks of > 6000 m Andean volcanoes that tower over the Atacama Desert, leaf‐eared mice (Phyllotis vaccarum) live at extreme elevations that surpass known vegetation limits. We used a combination of metagenomics, DNA metabarcoding, and stable isotope analyses to investigate the diet of mice living in these extreme environments.

Epistasis Constrains Mutational Pathways of Hemoglobin Adaptation in High-Altitude Pikas [PDF]

open access: yes, 2015
A fundamental question in evolutionary genetics concerns the roles of mutational pleiotropy and epistasis in shaping trajectories of protein evolution.

An Ecological Monitoring of the Plateau Pika and Its Impact on Grassland–An Experiment in the Yushu District, Qinghai Province of China [PDF]

open access: yes, 2020
The plateau pika (Ochotona curzoniae; see Fig.1 for photo) is a small mammal that lives in the alpine grasslands of the Tibetan Plateau. There are several uncertainties existing in the ecological behavior of the plateau pika and its impact on the alpine ...
