Risk assessment in the plateau pika (Ochotona curzoniae): intensity of behavioral response differs with predator species. [PDF]

BMC Ecol, 2020
Background The ability of a prey species to assess the risk that a predator poses can have important fitness advantages for the prey species. To better understand predator–prey interactions, more species need to be observed to determine how prey ...

Simulation and response mechanism of potential geographical distribution of plateau pika Ochotona curzoniae under climate change

Global Ecology and Conservation
With global warming, climate change had significant impacts on the distribution of species and their habitats. As one of the keystone species of the Qinghai-Tibet Plateau (QTP), the plateau pika Ochotona curzoniae plays a vital role in the alpine ...

Small mammalian herbivores at moderate densities facilitate livestock growth by improving vegetation composition in grasslands [PDF]

eLife
Small mammals and large herbivores have co-evolved in grasslands for millions of years, yet how they interact remains unclear. Although large herbivores can significantly affect the smaller ones, the reverse effect is largely unknown.

Can pikas hold the umbrella? Understanding the current and future umbrella potential of keystone species Pika (Ochotona spp.) [PDF]

Global Ecology and Conservation, 2022
The umbrella species concept is a frequently used concept in conservation since the conservation of an umbrella species may benefit other species. Keystone species are often suggested as potential umbrella species, but the validity of this approach ...

Late summer plateau pika spatial habitat use revealed by high‐resolution wildlife tracking and unmanned aerial vehicle data on the Qinghai–Tibet Plateau

Grassland Research
Background The Qinghai–Tibet Plateau has significant grassland degradation. The plateau pika (Ochotona curzoniae Hodgson), a small burrowing mammal, traditionally viewed as a pest, may strongly shape vegetation, yet its fine‐scale spatial ecology remains

Soil microbial communities and the associated effect on soil organic carbon in response to plateau pika bioturbation in alpine grasslands

Global Ecology and Conservation, 2023
Alpine grasslands are vital in regulating carbon balance on the Qinghai-Tibetan Plateau (QTP) because of the large soil organic carbon (SOC) stocks, while persistent disturbance from the endemic small semifossorial herbivore, plateau pika (Ochotona ...

Among-population divergence in personality is linked to altitude in plateau pikas (Ochotona curzoniae ) [PDF]

Frontiers in Zoology, 2019
Background Animals inhabiting high altitudes consistently show slow life-histories. The pace-of-life syndrome (POLS) hypothesis posits behavioural, physiological and/or morphological traits that mediate the trade-off between current and future ...

Parasite Species Associated With Wild Plateau Pika (Ochotona Curzoniae) In Southeastern Qinghai Province, China [PDF]

Journal of Wildlife Diseases, 2009
A survey was conducted to determine the prevalence and seasonal abundance of egg, larval, and adult stages of helminths; oocyts of protozoans; and ectoparasites of plateau pikas (Ochotona curzoniae) in seven areas of southeastern Qinghai Province, China,

A density estimation model of plateau pika (Ochotona curzoniae) supporting camera-monitoring programs. [PDF]

Ecol Evol, 2021
AbstractAs an important species in the Qinghai‐Tibet Plateau, the roles played by plateau pikas in grassland degradation and protection are controversial. The behavior characteristics and population density of this species are important in answering this question, but these traits have not been fully elucidated to date. Camera‐capture methods have been
