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.

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 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.

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 ...

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

Gut microbiome and antibiotic resistance genes in plateau model animal (Ochotona curzoniae) exhibit a relative stability under cold stress.

Journal of Hazardous Materials
Antibiotic resistance genes (ARGs) carried by gut pathogens may pose a threat to the host and ecological environment. However, few studies focus on the effects of cold stress on intestinal bacteria and ARGs in plateau animals. Here, we used 16S rRNA gene

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.

[Cloning and characterization of lactate dehydrogenase C4 from pika ochotona curzoniae].

Molekuliarnaia biologiia, 2015
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.
