Characterization of the spatial distribution of plateau pika burrows along an alpine grassland degradation gradient on the Qinghai–Tibet Plateau [PDF]

Ecology and Evolution, 2021
Plateau pika burrows are common feature of degraded grassland in the Qinghai–Tibet Plateau (QTP) and serve as an important indicator of pika activity and grassland degradation.

Animal Activities of the Key Herbivore Plateau Pika (Ochotona curzoniae) on the Qinghai-Tibetan Plateau Affect Grassland Microbial Networks and Ecosystem Functions [PDF]

Frontiers in Microbiology, 2022
Plateau pikas (Ochotona curzoniae) are high-altitude model animals and famous “ecosystem engineers” on the Qinghai-Tibet Plateau. Pika activities may accelerate the degradation of alpine meadows.

Species-Level Taxonomic Characterization of Uncultured Core Gut Microbiota of Plateau Pika [PDF]

Microbiology Spectrum, 2023
Rarely has the vast diversity of bacteria on Earth been profiled, particularly on inaccessible plateaus. These uncultured microbes, which are also known as “microbial dark matter,” may play crucial roles in maintaining the ecosystem and are linked to ...

A homotetrameric hemoglobin expressed in alveolar epithelial cells increases blood oxygenation in high-altitude plateau pika (Ochotona curzoniae) [PDF]

Cell Reports, 2022
Summary: The plateau pika (Ochotona curzoniae) is native to the Qinghai-Tibet Plateau. In this study, the gene that encodes a heme-binding protein in the pulmonary surfactant (PS) of the pika is identified. The protein is a homotetrameric hemoglobin (δ4)

Sex-Based Dietary Divergence in Plateau Pikas (Ochotona curzoniae) but Not Plateau Zokors (Eospalax baileyi) [PDF]

Animals
Quantifying sex-specific dietary differences in small mammals reveals the internal resource allocation mechanisms within a species and provides new insights for ecosystem management and conservation practices.

Dysbiosis of Gut Microbiome Aggravated Male Infertility in Captivity of Plateau Pika. [PDF]

Biomolecules
Captivity is an important and efficient technique for rescuing endangered species. However, it induces infertility, and the underlying mechanism remains obscure. This study used the plateau pika (Ochotona curzoniae) as a model to integrate physiological, metagenomic, metabolomic, and transcriptome analyses and explore whether dysbiosis of the gut ...

Spatiotemporal Coupling Relationship Between Plateau Pika Disturbance and Alpine Meadow Degradation [PDF]

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 ...

Modeling the Spatial Distribution of Plateau Pika (Ochotona curzoniae) in the Qinghai Lake Basin, China [PDF]

Animals, 2019
The plateau pika (Ochotona curzoniae) is a keystone species in the alpine rangeland ecosystem of the Qinghai−Tibetan Plateau. Most previous studies of habitat selection by plateau pika have been conducted at a local microhabitat scale; however ...

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.
