A highland-adaptation mutation of the Epas1 protein increases its stability and disrupts the circadian clock in the plateau pika

Cell Reports, 2022
Summary: The Qinghai-Tibet Plateau (QTP) harbors hundreds of species well adapted to its extreme conditions, including its low-oxygen (hypoxic) atmosphere.

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 ...

Analyzing the recovery mechanisms of patchy degradation and its response to mowing and plateau pika disturbances in alpine meadow

Ecological Indicators, 2023
The alpine meadow is susceptible to degradation triggered by overgrazing and rodent outbreaks, leading to uneven patches of degradation. In this regard, we conducted a study that involved the implementation of nine combined treatments utilizing a two ...

PRNP Sequences of Tibetan Antelope, Blue Sheep, and Plateau Pika from the Qinghai-Tibet Plateau and Reactivity of PrP Proteins to Rodent-Adapted Scrapie Strains in RT-QuIC and PMCA [PDF]

Zoonoses, 2023
Tibetan antelope ( Rhinopithecus ), blue sheep ( Pseudois nayauris ), and plateau pika ( Ochotona curzoniae ) are wild animals living on the Qinghai-Tibet Plateau.

Capturing Mechanism and Sustainable Control of Plateau Pika (Ochotona curzoniae) Using a Grassland Guidance Trap System on the Qinghai–Tibet Plateau [PDF]

Animals
Infestations of small terrestrial mammals (e.g., rodents and lagomorphs) on the Qinghai–Tibet Plateau pose formidable challenges, which are exacerbated by the region’s vast expanse and extreme environmental conditions.

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

Soil Organic Carbon Content and Density in Response to Pika Outbreaks Along the Altitudinal Gradient in Alpine Meadows of the Qinghai–Tibet Plateau, West China

Land
This study investigated the effects of plateau pika (Ochotona curzoniae) disturbances and altitude on soil organic carbon (SOC) storage characteristics, including SOC content and SOC density (SOCD).
