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

Arctic, 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.

Effect of Plateau Pika Disturbance on Plant Aboveground Biomass of Alpine Meadows at Two Different Scales [PDF]

Plants, 2022
Disturbance by small burrowing herbivores often has an impact on plant aboveground biomass of grassland because it makes grasslands into a mosaic of discrete vegetated surfaces and bare soil patches.

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

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 ...

The expression of Ldh-c in the skeletal muscle of plateau pika (Ochotona curzoniae) enhances adaptation to a hypoxic environment [PDF]

Biology Open, 2017
The plateau pika (Ochotona curzoniae) is a species of sprint-running alpine animals in the Qinghai-Tibet Plateau, which is a harsh highland hypoxic environment. Ldh-c is expressed in the testis, sperm and somatic tissues of plateau pika.

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

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

Ecol 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.
