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 ...

Plateau Pika (Ochotona curzoniae) Disturbance Alters Soil‐Microbe‐Enzyme C–N–P Stoichiometry and Drives a Shift From N‐ to P‐Limitation in Alpine Meadows on the Qinghai‐Tibet Plateau

Land Degradation & Development
Soil‐microbe‐enzyme C–N–P stoichiometry is a key indicator of nutrient cycling and ecosystem resilience. This study examines its response to plateau pika (Ochotona curzoniae) disturbance in alpine meadows on the Qinghai‐Tibet Plateau.

Virus communities are associated with the degradation of recalcitrant carbon during the corpse decay of plateau pika (Ochoton curzoniae)

Grassland Research
It has been reported that bacteria and fungi play a vital role in soil biogeochemical cycles during the decomposition of animal corpses. However, it is poorly understood how the viral composition and function of grassland soil change during the decay of ...

Disturbance Gradients of Plateau Pika ( Ochotona curzoniae ) Reshape Soil Microbiome Communities in Qinghai–Tibetan Plateau Ecosystems

Land Degradation & Development
The plateau pika ( Ochotona curzoniae ) is recognized as an ecosystem engineer on the Qinghai–Tibetan Plateau (QTP). Despite the critical roles that soil microbiomes play in ecosystem functioning, little is known about how the disturbance ...

Microclimate response of soil to plateau pika's disturbance in the northeast Qinghai‐Tibet Plateau

European Journal of Soil Science, 2018
Summary The plateau pika ( Ochotona curzoniae ) is one of the main native soil faunas on the Qinghai‐Tibet Plateau and plays a key role in the terrestrial ecosystem there.

The plateau pika (Ochotona curzoniae) is a keystone species for biodiversity on the Tibetan plateau

Animal Conservation, 1999
AbstractIt is necessary to look at the big picture when managing biological resources on the Qinghai—Xizang (Tibetan) plateau. Plateau pikas (Ochotona curzoniae) are poisoned widely across the plateau. Putative reasons for these control measures are that pika populations may reach high densities and correspondingly reduce forage for domestic livestock (

Livestock grazing, plateau pikas and the conservation of avian biodiversity on the Tibetan plateau

Biological Conservation, 2008
On the Qinghai-Tibet plateau increased livestock numbers have resulted in degradation of the grasslands with potential impacts on native biodiversity. Concurrently, perceived increases in populations of native small mammals such as plateau pikas (Ochotona curzoniae) have led to poisoning programs, with uncertain impacts on species such as ground ...

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 ...

Plateau pika interferes with the relationship between biodiversity and ecosystem multifunctionality in alpine meadows

Ecological research
Plateau pikas alter alpine meadow biodiversity and ecosystem functions via foraging, burrowing, and excretion. While plant and soil biodiversity synergistically regulate ecosystem multifunctionality (EMF), their relative contributions under varying pika ...
