Age-Specific Composition and Predicted Function of Gut Microbiota in Plateau Pikas (Ochotona curzoniae). [PDF]

Biology (Basel)
Gut microbes play a crucial role in regulating physiological processes such as host energy metabolism, nutrient absorption, and environmental adaptation. The predicted functions of gut microbes can be influenced by many factors, both extrinsic and intrinsic to the hosts.

The burying and grazing effects of plateau pika on alpine grassland are small: a pilot study in a semiarid basin on the Qinghai-Tibet Plateau [PDF]

Biogeosciences, 2016
There is considerable controversy about the effects of plateau pika (Ochotona curzoniae, hereafter pika) on alpine grassland on the Qinghai-Tibet Plateau (QTP). On the one hand, pika is considered a keystone species.

Soil microbial communities and the associated effect on soil organic carbon in response to plateau pika bioturbation in alpine grasslands

Global Ecology and Conservation, 2023
Alpine grasslands are vital in regulating carbon balance on the Qinghai-Tibetan Plateau (QTP) because of the large soil organic carbon (SOC) stocks, while persistent disturbance from the endemic small semifossorial herbivore, plateau pika (Ochotona ...

Agromyces badenianii sp. nov., isolated from plateau pika (Ochotona curzoniae)

International Journal of Systematic and Evolutionary Microbiology, 2020
Two aerobic, Gram-stain-positive, catalase-positive, non-motile and rod-shaped bacterial strains, designated MF30-AT and MF845, were isolated from the intestinal contents of plateau pika collected from the Qinghai–Tibet Plateau. Optimal growth of these two strains was observed under aerobic conditions at pH 7.0 and 28 °C. The 16S rRNA gene sequences of

Small Semi-Fossorial Herbivores Affect the Allocation of Above- and Below-Ground Plant Biomass in Alpine Meadows

Frontiers in Plant Science, 2022
Small semi-fossorial herbivores can affect plant aboveground biomass (AGB) in grasslands and possibly alter the allocation of AGB and belowground biomass (BGB).

Spatiotemporal Coupling Relationship Between Plateau Pika Disturbance and Alpine Meadow Degradation

Shuitu baochi tongbao, 2023
[Objective] Plateau pika (Ochotona curzoniae) is a key species in the alpine meadow ecosystem of the Qinghai-Xizang Plateau. The coupling relationship between pika activity and meadow degradation was analyzed in order to further improve the observation ...

Architecture Characteristics of Burrow System of Plateau Pika, Ochotona curzoniae

Pakistan Journal of Zoology, 2018
Burrows serve many functions for animals by providing a place for rearing young, sleeping, hibernation, food storage, protection from predators and extreme environment, and the function of burrows varies with the degree of burrow complexity. We studied the burrow architecture (length, internal dimensions, fractal dimension of tunnel systems, number of ...

Discovery and Evolution of a Divergent Coronavirus in the Plateau Pika From China That Extends the Host Range of Alphacoronaviruses

Frontiers in Microbiology, 2021
Although plateau pikas are the keystone species in the plateau ecosystem of the Qinghai Province of China, little is known about their role in the evolution and transmission of viral pathogens, especially coronaviruses.

Actinomyces gaoshouyii sp. nov., isolated from plateau pika (Ochotona curzoniae)

International Journal of Systematic and Evolutionary Microbiology, 2017
Two strains (pika_113T and pika_114) of a previously undescribed Actinomyces-like bacterium were recovered from the intestinal contents of plateau pika (Ochotona curzoniae) on the Tibet-Qinghai Plateau, China. Results from biochemical characterization indicated that the two strains were phenotypically homogeneous and distinct from other previously ...
