Biogeographical Study of Plateau PikasOchotona curzoniae(Lagomorpha, Ochotonidae)
Zoological Science, 2012We reconstructed the demographic history of the plateau pika (Ochotona curzoniae) on the Qinghai-Tibetan plateau by using genetic variation data obtained from spatially distributed populations across much of the plateau. We obtained sequence data, including cob (1,140 bp) and D-loop sequences (732 bp), from 144 individuals at sites ranging from the ...

Independence between coping style and stress reactivity in plateau pika
Physiology & Behavior, 2018The concept of coping style represents the way individual animals react to a stressful situation, both behaviourally and neurophysiologically. Over the last decades coping style has been linked to the development of research on animal personality. Based on this concept, we should find a proactive-reactive continuum in animal populations, with proactive

Seasonal thermogenesis and body mass regulation in plateau pikas (Ochotona curzoniae)
Oecologia, 2006Changes in photoperiod, ambient temperature and food availability trigger seasonal acclimatization in physiology and behavior of many animals. In the present study, seasonal adjustments in body mass and in several physiological, hormonal, and biochemical markers were examined in wild-captured plateau pikas (Ochotona curzoniae) from the Qinghai-Tibetan ...

Microclimate response of soil to plateau pika's disturbance in the northeast Qinghai‐Tibet Plateau
European Journal of Soil Science, 2018Summary The plateau pika ( Ochotona curzoniae ) is one of the main native soil faunas on the Qinghai‐Tibet Plateau and plays a key role in the terrestrial ecosystem there.

Livestock grazing, plateau pikas and the conservation of avian biodiversity on the Tibetan plateau
Biological Conservation, 2008On the Qinghai-Tibet plateau increased livestock numbers have resulted in degradation of the grasslands with potential impacts on native biodiversity. Concurrently, perceived increases in populations of native small mammals such as plateau pikas (Ochotona curzoniae) have led to poisoning programs, with uncertain impacts on species such as ground ...

AbstractUnderstanding a species' functional traits allows for a directed and productive perspective on the role a species plays in nature, and thus its relative importance to conservation planning. The functional‐trait ecology of the plateau pika Ochotona curzoniae is examined to better understand the resilience and sustainability of the high alpine ...

Metabolic Alterations of Qinghai–Tibet Plateau Pikas in Adaptation to High Altitude
High Altitude Medicine & Biology, 2017Cao, Xue-Feng, Zhen-Zhong Bai, Lan Ma, Shuang Ma, and Ri-Li Ge. Metabolic alterations of Qinghai-Tibet plateau pikas in adaptation to high altitude. High Alt Med Biol. 18:219-225, 2017.-To determine specific metabolic alterations in the myocardium of plateau pikas (Ochotona curzoniae) and potential metabolic biomarkers involved in their adaptation to ...

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

Life history of the plateau pika (Ochotona curzoniae) in alpine meadows of the Tibetan Plateau
Mammalian Biology, 2013The life history of a species is a result of natural selection and reflects how the species is adapted to its environment. Knowledge of life history is crucial for further ecological studies and conservation management. This paper presents aspects of the life history of the plateau pika (Ochotona curzoniae), a small mammal native to alpine meadows of ...

Dispersal, which is a crucial process in animal population and evolutionary ecology, is considered personality dependent. The fitness consequences of dispersal are important. However, they are difficult and rarely measured in wild populations. In this study, we investigated the behaviour and reproductive fitness in a plateau pika (Ochotona curzoniae ...
