Pika’s role in the Qinghai-Tibet Plateau ecosystem and effects of biodiversity [PDF]

BIO Web of Conferences
The Tibetan Plateau is the largest plateau in the world. Although this plateau is not as rich in species as the rainforest, it still contains some specific flora and fauna (including mammals, birds, and some reptiles).

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.

Spatiotemporal Distribution Patterns of Plateau Foxes and Their Lagomorph Prey in Baqing County, Tibet [PDF]

Ecology and Evolution
Predation by carnivores is a fundamental driver of species evolution, shaping interspecific spatiotemporal dynamics and prey behavior. To examine predator–prey‐driven spatiotemporal coexistence patterns between foxes and pikas on the Qinghai‐Tibetan ...

Effects of Plateau Pika Disturbance on the Spatial Heterogeneity of Vegetation in Alpine Meadows. [PDF]

Front Plant Sci, 2021
Herbivory is one of the important factors that influence spatial heterogeneity of vegetation in grasslands. In this study, we focused on plateau pika (Ochotona curzoniae) to investigate the effects of the presence of small semi-fossorial herbivores and their disturbance intensity on the spatial heterogeneity of vegetation in alpine meadows across three

Genetic diversity and sex-bias dispersal of plateau pika in Tibetan plateau. [PDF]

Ecol Evol, 2017
AbstractDispersal is an important aspect in organism's life history which could influence the rate and outcome of evolution of organism. Plateau pika is the keystone species in community of grasslands in Tibetan Plateau. In this study, we combine genetic and field data to character the population genetic pattern and dispersal dynamics in plateau pika ...

Spatiotemporal Coupling Relationship Between Plateau Pika Disturbance and Alpine Meadow Degradation

Shuitu baochi tongbao, 2023
[Objective] Plateau pika (Ochotona curzoniae) is a key species in the alpine meadow ecosystem of the Qinghai-Xizang Plateau. The coupling relationship between pika activity and meadow degradation was analyzed in order to further improve the observation ...

Group-living decrease predation risk of individual: Evidence from behavior, hormones and reproduction of plateau pika

Frontiers in Ecology and Evolution, 2023
Extensive research confirms that abiotic stressors like predation risk can profoundly affect animal condition. However, there is a lack of experimental research assessing the suite of physiological responses to risk.

Research Progress on Plateau Pika Dynamic Distribution in the Context of Climate Change and Human Activities

Nantong Daxue xuebao. Ziran kexue ban, 2020
Plateau pika is an endemic species of the Qinghai-Tibet Plateau and a key species of alpine grassland ecosystem, but its outbreak under certain conditions will also bring adverse effects on the alpine grassland, so it has received wide concerns.

Microhabitat use by plateau pikas: living on the edge [PDF]

Journal of Mammalogy, 2019
AbstractMammals rely on habitat resources for survival and reproduction. We studied microhabitats used by plateau pikas (Ochotona curzoniae) of the Qinghai-Tibetan Plateau. Microhabitat features used by pikas include sedge meadows that provide forage, burrows that provide safety from predators and cover for nests, degraded open-dirt patches, and edges ...
