Reproduction of plateau pika (Ochotona curzoniae) on the Qinghai–Tibetan plateau

European Journal of Wildlife Research, 2011
The reproduction of the plateau pika (Ochotona curzoniae) was investigated in Guoluo District at an elevation of 4,000 m on the Qinghai–Tibetan plateau, China, from April 2007 to August 2008. Reproduction was seasonal, and the breeding season lasted from April to late June/early July.

Male reproductive success in plateau pikas (Ochotona curzoniae): A microsatellite analysis

Mammalian Biology, 2009
In many social species, competition and cooperation between group members may lead to a large variance in reproductive success among individuals, especially for adult male. From April to August 2002, we studied the adult male reproductive success of plateau pikas in Haibei Alpine Meadow Ecosystem Research Station, Chinese Academy of Science, using ...

Functional‐trait ecology of the plateau pika Ochotona curzoniae in the Qinghai–Tibetan Plateau ecosystem

Integrative Zoology, 2019
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 ...

Lowly pathogenic avian influenza (H9N2) infection in Plateau pika (Ochotona curzoniae), Qinghai Lake, China

Veterinary Microbiology, 2014
Avian influenza viruses (AIVs) are globally important contagions. Several domestic mammals can be infected with AIVs and may play important roles in the adaptation and transmission of these viruses in mammals, although the roles of wild mammals in the natural ecology of AIVs are not yet clear.

Five-year population dynamics of plateau pikas (Ochotona curzoniae) on the east of Tibetan Plateau

European Journal of Wildlife Research, 2017
Small 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

Two community types occur in gut microbiota of large‐sample wild plateau pikas (Ochotona curzoniae)

Integrative Zoology, 2021
AbstractStudies on large‐sample gut microbial sequencing data indicate that gut microbiota can be divided into multiple community types; different community types may influence the community function and ecosystem service. However, the knowledge on the classification, diversity, interaction, and assembling of microbial community types in the gut of ...

Life history of the plateau pika (Ochotona curzoniae) in alpine meadows of the Tibetan Plateau

Mammalian Biology, 2013
The 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 ...

Modeling dispersal of the plateau pika (Ochotona curzoniae) using a cellular automata model

Ecological Modelling, 2007
The 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.

Behaviour and reproductive fitness of postdispersal in plateau pikas (Ochotona curzoniae) on the Tibetan Plateau

Mammal Research, 2017
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 ...

Intermittent cold exposure results in visceral adipose tissue “browning” in the plateau pika (Ochotona curzoniae)

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 ...
