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

open access: yesAnimals, 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 ...

Return of the pika: American pikas re‐occupy long‐extirpated, warm locations

open access: yesEcology and Evolution, 2022
AbstractAmerican pikas (Ochotona princeps), small mammals related to rabbits, occur in mountainous regions of western North America, where they live in shattered‐rock habitats (talus). Aspects of their physiology and life history create situations that appear to put pikas at risk from warming climates.

Plastic pikas: Behavioural flexibility in low-elevation pikas (Ochotona princeps) [PDF]

open access: yesBehavioural Processes, 2016
Behaviour is an important mechanism for accommodating rapid environmental changes. Understanding a species' capacity for behavioural plasticity is therefore a key, but understudied, aspect of developing tractable conservation and management plans under climate-change scenarios.

Differential Expression of Metabolism-Related Genes in Plateau Pika (Ochotona curzoniae) at Different Altitudes on the Qinghai–Tibet Plateau

open access: yesFrontiers in Genetics, 2022
According to life history theory, animals living in extreme environments have evolved specific behavioral and physiological strategies for survival. However, the genetic mechanisms underpinning these strategies are unclear.

Transcriptome analysis of pika heart tissue reveals mechanisms underlying the adaptation of a keystone species on the roof of the world

open access: yesFrontiers in Genetics, 2022
High-altitude environments impose intense stresses on living organisms and drive striking phenotypic and genetic adaptations, such as hypoxia resistance, cold tolerance, and increases in metabolic capacity and body mass. As one of the most successful and

Group-living decrease predation risk of individual: Evidence from behavior, hormones and reproduction of plateau pika

open access: yesFrontiers in Ecology and Evolution, 2023
Extensive research confirms that abiotic stressors like predation risk can profoundly affect animal condition. However, there is a lack of experimental research assessing the suite of physiological responses to risk.

Research Progress on Plateau Pika Dynamic Distribution in the Context of Climate Change and Human Activities

open access: yesNantong Daxue xuebao. Ziran kexue ban, 2020
Plateau pika is an endemic species of the Qinghai-Tibet Plateau and a key species of alpine grassland ecosystem, but its outbreak under certain conditions will also bring adverse effects on the alpine grassland, so it has received wide concerns.

Using UAVs to assess the relationship between alpine meadow bare patches and disturbance by pikas in the source region of Yellow River on the Qinghai-Tibetan Plateau

open access: yesGlobal Ecology and Conservation, 2021
Degradation of the alpine meadow has received increasing attention recently, and plateau pika (Ochotona curzoniae, hereafter pika) disturbance is considered as an important cause.
