Gut microbiome adaptation to extreme cold winter in wild plateau pika (Ochotona curzoniae) on the Qinghai-Tibet Plateau

FEMS Microbiology Letters, 2020
The Qinghai-Tibet Plateau (QTP) is harsh environment characterized by low temperature, high altitude and hypoxia, while some native mammals may well adapt to the extreme climate. However, how animal gut microbial community structure and function adapt to

Summer habitat use of plateau pikas (Ochotona curzoniae) in response to winter livestock grazing in the alpine steppe Qinghai-Tibetan Plateau

Arctic, Antarctic, and Alpine Research, 2018
Plateau pikas (Ochotona curzoniae), burrowing lagomorphs endemic to the Qinghai-Tibetan Plateau (QTP), are considered pests by Chinese authorities because of their association with grasslands that are characterized as degraded.

Late summer plateau pika spatial habitat use revealed by high‐resolution wildlife tracking and unmanned aerial vehicle data on the Qinghai–Tibet Plateau

Grassland Research
Background The Qinghai–Tibet Plateau has significant grassland degradation. The plateau pika (Ochotona curzoniae Hodgson), a small burrowing mammal, traditionally viewed as a pest, may strongly shape vegetation, yet its fine‐scale spatial ecology remains

The distribution and behavioral characteristics of plateau pikas (Ochotona curzoniae) [PDF]

ZooKeys, 2021
Plateau pikas (Ochotona curzoniae) are regarded as one of the main causes of the degradation of alpine meadows in the Qinghai-Tibet Plateau (QTP). The population density of plateau pikas is directly related to the degree of grassland damage.

Cardiac adaptation to high altitude in the plateau pika (Ochotona curzoniae). [PDF]

Physiol Rep, 2013
The aim of this study was to assess maximal heart rate (HR) and heart morphological changes in high altitude living "plateau pikas" and rats bred at 2260 m. Rats and pikas were catheterized to measure HR (2260 m). After baseline measurements, 1 mg/kg of atropine (AT) and increasing doses of isoproterenol (IsoP) (0.1, 1, 10, and 100 μg kg) were injected

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.

Transcriptome analysis of pika heart tissue reveals mechanisms underlying the adaptation of a keystone species on the roof of the world

Frontiers in Genetics, 2022
High-altitude environments impose intense stresses on living organisms and drive striking phenotypic and genetic adaptations, such as hypoxia resistance, cold tolerance, and increases in metabolic capacity and body mass. As one of the most successful and

Gut region influences the diversity and interactions of bacterial communities in pikas (Ochotona curzoniae and Ochotona daurica) [PDF]

FEMS Microbiology Ecology, 2017
The mammalian microbial communities in the gastrointestinal tract (GIT) play important roles in host nutrition and health. However, we still lack an understanding of how these communities are organized across GIT in natural environments. Here, using 16S rRNA gene sequencing, we analyzed the bacterial community diversity, network interactions and ...
