YOLO-Pika: a lightweight improved model of YOLOv8n incorporating Fusion_Block and multi-scale fusion FPN and its application in the precise detection of plateau pikas [PDF]

Frontiers in Plant Science
The plateau pika (Ochotona curzoniae) is a keystone species on the Qinghai–Tibet Plateau, and its population density—typically inferred from burrow counts—requires rapid, low-cost monitoring.

Moderate plateau pika activity had minor effect on ecosystem C and N in alpine grasslands

Global Ecology and Conservation
Plateau pika (Ochotona curzoniae, hereafter pika) is an ecosystem engineer on the Qinghai-Tibetan Plateau (QTP), whose activity exerts a profound effect on the ecosystem nutrient cycle of alpine grasslands.

Shiga Toxin-Producing Escherichia coli in Plateau Pika (Ochotona curzoniae) on the Qinghai-Tibetan Plateau, China [PDF]

Frontiers in Microbiology, 2016
Shiga toxin-producing Escherichia coli (STEC) are an emerging group of zoonotic pathogens. Ruminants are the natural reservoir of STEC. In this study we determined the prevalence and characteristics of the STEC in plateau pika (Ochotona curzoniae) on the

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 ...

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.
