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 ...

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

The plateau pika has multiple benefits for alpine grassland ecosystem in Qinghai–Tibet Plateau [PDF]
Ecosystem Health and Sustainability, 2020 The plateau pika (Ochotona curzoniae) has been engaged in pest control for many years based on the logic that the plateau pika is responsible for alpine grassland degradation and competes with livestock for forage resources.

Functional evolution of leptin of Ochotona curzoniae in adaptive thermogenesis driven by cold environmental stress. [PDF]
PLoS ONE, 2011 BackgroundEnvironmental stress can accelerate the directional selection and evolutionary rate of specific stress-response proteins to bring about new or altered functions, enhancing an organism's fitness to challenging environments.

Vitamin D3 Metabolic Enzymes in Plateau Zokor (Myospalax baileyi) and Plateau Pika (Ochotona curzoniae): Expression and Response to Hypoxia [PDF]
Animals, 2022 Vitamin D3 (D3) is produced endogenously from 7-dehydrocholesterol by irradiation and is an important secosteroid for the absorption of calcium and phosphate.

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.

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 ...

Deoxycholic acid derived from the gut microbiota involved in the regulation of adaptive thermogenesis in response to dietary protein restriction in plateau pika. [PDF]
MicrobiomeMost winter-active mammals experience protein restriction. Gut microbiota is a key regulator of host energy homeostasis during nutrient deficiency, yet cross talk between microbiota and factors (e.g., hormones, signaling molecules) that regulate host ...
