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 ...

Social Relationships of Adult Black-Lipped Pikas (Ochotona curzoniae)

Journal of Mammalogy, 1991
Adult spatial and social relationships in a marked population of black-lipped pikas ( Ochotona curzoniae ) were studied during the reproductive season from April to July near Qinghai Lake, People's Republic of China. Families of pikas occupied relatively discrete home ranges that contained a burrow system with many entrances in continuous alpine-meadow

Cloning and characterization of lactate dehydrogenase C4 from Ochotona curzoniae

Molecular Biology, 2014
Lactate dehydrogenase C4 (LDH-C4) is considered to be a good target protein for the development of contraceptive drugs. To develop contraceptive rodenticide against pika (Ochotona curzoniae) LDH-C4, the pika LDH-C gene was cloned and expressed in Escherichia coli. The recombinant protein was purified and characterized.

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 ...

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

Mitochondrial genome analysis of Ochotona curzoniae and implication of cytochrome c oxidase in hypoxic adaptation

Mitochondrion, 2008
Pikas originated in Asia and are small lagomorphs native to cold climates. The plateau pika, Ochotona curzoniae is a keystone species on the Qinghai-Tibet Plateau and an ideal animal model for hypoxic adaptation studies. Altered mitochondrial function, especially cytochrome c oxidase activity, is an important factor in modulation of energy generation ...

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.

Effects of temperature and photoperiod on thermogenesis in plateau pikas ( Ochotona curzoniae ) and root voles ( Microtus oeconomus )

Journal of Comparative Physiology B: Biochemical, Systemic, and Environmental Physiology, 1999
We examined the effects of temperature and photoperiod on metabolic thermogenesis and the thermogenic characteristics of brown adipose tissue in plateau pikas (Ochotona curzoniae) and root voles (Microtus oeconomus), the dominant species of small mammals in the alpine meadow ecosystems on the Qinghai-Tibetan Plateau.
