Disrupted circadian rhythms in the plateau pika

Trends in Neurosciences, 2023
The plateau pika (Ochotona curzoniae) is the most populous mammal on the 'third pole', the Qinghai-Tibet Plateau, and is presumed to have inhabited the region before the plateau rose up from sea level. Herein we discuss the disrupted circadian rhythm in the plateau pika and the gene polymorphism behind this phenotype, placing these findings in the ...

The mating system and gene dynamics of plateau pikas

Behavioural Processes, 2000
Evolutionary theory suggests that mating systems should have substantial effects on gene dynamics of local populations. In polygynous species, local 'breeding groups' may produce significant genetic structure, due to genetic differences among groups, and rate of loss of genetic variation from such populations may be considerably slowed.

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.

First genotyping of Enterocytozoon bieneusi in plateau pikas (Ochotona curzoniae) from the Qinghai Plateau, Northwest China

Veterinary Research Communications, 2021
Enterocytozoon bieneusi is considered the most common microsporidian species and is frequently detected in humans and various animals worldwide. However, information on E. bieneusi infection in plateau pikas (Ochotona curzoniae) is somewhat limited. Therefore, this study was conducted to determine the infection status and genotype characteristics of E.

Behavioral mechanisms of male sterilization on plateau pika in the Qinghai-Tibet plateau

Behavioural Processes, 2012
Fertility control is an alternative non-lethal method in the management of rodents. Previous modeling suggests that the efficacy of male sterilization depends on mating systems of animals, but behavioral mechanisms of male sterilization have not been investigated. Here we investigated the behavioral mechanism of the sterilant quinestrol in reducing the

Clipping by Plateau Pikas and Impacts to Plant Community

Rangeland Ecology & Management, 2020
Abstract Plateau pikas (Ochotona curzoniae) often clip tall plants near active burrow entrances to detect and avoid predators. This clipping behavior influencing plant communities near active burrow entrances has not been well documented. A field experiment was conducted to investigate the effects of this clipping behavior on plant communities across

Biogeographical Study of Plateau PikasOchotona curzoniae(Lagomorpha, Ochotonidae)

Zoological Science, 2012
We 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, 2018
The 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

A non-destructive method for three-dimensional characterizing plateau pika's burrow system.

Journal of Environmental Management
The plateau pika's burrow system exerts a significant influence on the alpine ecosystem. However, current methods are insufficient for accurately characterizing its spatial structure. In this study, we utilized drone imagery and ground-penetrating radar (GPR) scanning in alpine grasslands on the eastern edge of the Qinghai-Tibetan Plateau (QTP).
