Five-year population dynamics of plateau pikas (Ochotona curzoniae) on the east of Tibetan Plateau
European Journal of Wildlife Research, 2017Small mammals mediate trajectories of vegetation change where both their density and the growing season are moderated by temperature and precipitation. On the Tibetan Plateau, the cold and arid climate particularly restricts the plant growing season, but the role of mammals’ density and climate in moderating small mammal populations remains unknown. We

The plateau pika (Ochotona curzoniae) is a keystone species for biodiversity on the Tibetan plateau
Animal Conservation, 1999AbstractIt is necessary to look at the big picture when managing biological resources on the Qinghai—Xizang (Tibetan) plateau. Plateau pikas (Ochotona curzoniae) are poisoned widely across the plateau. Putative reasons for these control measures are that pika populations may reach high densities and correspondingly reduce forage for domestic livestock (

The plateau pika, a typical hypoxia-tolerant mammal lives 3000-5000 m above sea level on the Qinghai-Tibet Plateau, has acquired many physiological and morphological characteristics and strategies in its adaptation to sustained, high-altitude hypoxia.

Modeling dispersal of the plateau pika (Ochotona curzoniae) using a cellular automata model
Ecological Modelling, 2007The plateau pika is a keystone species of the Qinghai-Xizang plateau. We ought to intensify the inspection and management about its population dynamics in order to bring it to appropriate spatio-temporal distribution, play the role of keystone species, and do not destroy the alpine grasslands.

We examined the effects of temperature and photoperiod on metabolic thermogenesis and the thermogenic characteristics of brown adipose tissue in plateau pikas (Ochotona curzoniae) and root voles (Microtus oeconomus), the dominant species of small mammals in the alpine meadow ecosystems on the Qinghai-Tibetan Plateau.

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2015
The plateau pika has developed tolerance to cold and hypoxia in order to adapt to living in the extreme environment of the Qinghai-Tibetan Plateau. One mammalian mechanism for cold adaptation is thermogenesis by brown adipose tissue (BAT), but the degree to which pika exploits this mechanism or how it may be modified by the additional stresses of high ...

Plateau zokor (Myospalax baileyi) and plateau pika (Ochotona curzniae) are native to the Qinghai-Tibet plateau. To study their adaptive mechanisms, the ratios of heart weight to body weight (HW/BW) and right to left ventricular plus septum weights [RV/(LV+S)] were determined; the microvessel density (MVD) of cardiac muscle were measured by ...

Plateau pika (Ochotona curzoniae) burrowing greatly influences ecosystem multifunctionality (EMF) in alpine grasslands. However, the degree to which this activity would affect EMF in alpine grasslands lack general cognition. Here, we examined pika burrowing impacts on EMF across elevation gradients in alpine grasslands. The results furnished compelling
