Can pikas hold the umbrella? Understanding the current and future umbrella potential of keystone species Pika (Ochotona spp.)

Global Ecology and Conservation, 2022
The umbrella species concept is a frequently used concept in conservation since the conservation of an umbrella species may benefit other species. Keystone species are often suggested as potential umbrella species, but the validity of this approach ...

YOLO-Pika: a lightweight improved model of YOLOv8n incorporating Fusion_Block and multi-scale fusion FPN and its application in the precise detection of plateau pikas [PDF]

Frontiers in Plant Science
The plateau pika (Ochotona curzoniae) is a keystone species on the Qinghai–Tibet Plateau, and its population density—typically inferred from burrow counts—requires rapid, low-cost monitoring.

Monitoring Plateau Pika and Revealing the Associated Influencing Mechanisms in the Alpine Grasslands Using Unmanned Aerial Vehicles

Drones
Plateau pika (Ochotona curzoniae, hereafter pika) is a key species in the alpine grasslands on the Qinghai-Tibetan Plateau (QTP). They are susceptible to the influence of external disturbance and may present great variation, which is important to ...

Spatiotemporal Distribution Patterns of Plateau Foxes and Their Lagomorph Prey in Baqing County, Tibet [PDF]

Ecology and Evolution
Predation by carnivores is a fundamental driver of species evolution, shaping interspecific spatiotemporal dynamics and prey behavior. To examine predator–prey‐driven spatiotemporal coexistence patterns between foxes and pikas on the Qinghai‐Tibetan ...

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 ...

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

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.

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.
