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

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 ...

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 ...

Response of Plant Phylogenetic Structure to Plateau Pika ( Ochotona curzoniae ) Disturbance on Alpine Meadow of Qinghai‐Tibetan Plateau

Land Degradation & Development
Plant community construction is influenced by bottom‐up processes, such as environmental factors, and top‐down processes, such as herbivore disturbances.

Bartonella Species Detected in the Plateau Pikas (Ochotona curzoiae) from Qinghai Plateau in China.

Biomedical and environmental sciences : BES, 2016
Bartonella species can infect a variety of mammalian hosts and cause a broad spectrum of diseases in humans, but there have been no reports of Bartonella infection in Ochotonidae. This is the first study to detect Bartonella in plateau pikas in the Qinghai plateau, providing baseline data for the risk assessment of human Bartonella infection in this ...

Plateau pikas burrowing activity accelerates ecosystem carbon emission from alpine grassland on the Qinghai-Tibetan Plateau

Ecological Engineering, 2015
Abstract Pikas ( Ochotona curzoniae ) are common on the Qinghai-Tibetan Plateau (QTP). However, little is known about the effect of their burrowing activity on carbon emissions from alpine grassland ecosystems. In this study, we investigated soil organic carbon (SOC), total nitrogen (TN) density and ecosystem CO 2 flux from the original vegetation ...

Adlercreutzia wanghongyangiae sp. nov., and Adlercreutzia shanghongiae sp. nov., two new members of the genus Adlercreutzia isolated from plateau pika (Ochotona curzoniae).

International Journal of Systematic and Evolutionary Microbiology
Four anaerobic, Gram-stain-positive, non-motile, non-sporulating rod-shaped bacterial strains (R7T, R21, R22 and R25T) were isolated from the intestinal contents of plateau pika (Ochotona curzoniae) collected from the Qinghai-Tibet Plateau, PR China. The

Functional regulation of testosterone underlying state transition in seasonal spermatogenesis of Plateau Pika (Ochotona curzoniae)

Journal of Mammalogy
Seasonal reproduction is an adaptive strategy that benefits the survival and growth of offspring. However, the regulatory mechanisms affecting spermatogenesis in male seasonal breeders are not well understood.

Habitat-induced changes in forage quality and implications for fitness in Plateau Pika (Ochotona curzoniae)

Journal of Mammalogy
Plateau pikas (Ochotona curzoniae) play a keystone role in the alpine meadow ecosystem on the Qinghai–Tibetan Plateau (QTP). For decades, QTP grasslands have become degraded to some degree, largely as a result of heavy livestock grazing.
