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

open access: yesGlobal 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 ...

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

open access: goldArctic, 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.

The plateau pika has multiple benefits for alpine grassland ecosystem in Qinghai–Tibet Plateau [PDF]

open access: yesEcosystem 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.

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

open access: goldZooKeys, 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.

Identifying Conservation and Conflict Zones for Tibetan Brown Bears Under Climate Change Through Integrated Habitat and Prey Modeling on the Qinghai-Tibet Plateau. [PDF]

open access: yesEcol Evol
This study evaluates the future habitat dynamics of the Tibetan brown bear on the Qinghai‐Tibet Plateau under climate change by integrating predator–prey relationships and environmental variables using the MaxEnt model. Results show significant habitat contraction and shifting patterns, increasing the risk of human‐bear conflict.

Functional evolution of leptin of Ochotona curzoniae in adaptive thermogenesis driven by cold environmental stress. [PDF]

open access: yesPLoS 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.

The Utilization of Artificial Burrows by Plateau Pikas Under Rapid Vegetation Restoration. [PDF]

open access: yesEcol Evol
Vegetation changes often elicit adaptive responses in herbivores. Plateau pikas do not prefer to cope with rapid vegetation changes by adjusting the use of spatial resources. Instead, burrow accessibility and scent‐marking potential—driven by morphological preferences—are the primary determinants shaping their spatial resource selection.

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]

open access: yesBiogeosciences, 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.

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]

open access: yesFrontiers 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.
