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.

Seasonal thermogenesis and body mass regulation in plateau pikas (Ochotona curzoniae)

Oecologia, 2006
Changes 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 ...

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 ...

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 ...

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.

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 ...

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 ...

Effects of quinestrol and levonorgestrel on populations of plateau pikas, Ochotona curzoniae , in the Qinghai‐Tibetan Plateau

Pest Management Science, 2012
Abstract BACKGROUND: Plateau pikas ( Ochotona curzoniae , Hodgson, 1858) are viewed as a pest in the Tibetan Plateau meadow ecosystem when their population densities are high.

Isolation and characterization of 13 microsatellite loci in the plateau pika (Ochotona curzoniae)

Conservation Genetics, 2008
High quality jumping microsatellite libraries of the plateau pika (Ochotona curzoniae) were constructed; 231 out of the 288 clones contained microsatellite repeat motif and 120 pairs of primers were designed accordingly. Polymorphism was assessed for 48 individuals. Only 13 microsatellite loci were polymorphic with high polymorphism information content

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 ...
