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

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.

Reproduction of plateau pika (Ochotona curzoniae) on the Qinghai–Tibetan plateau

European Journal of Wildlife Research, 2011
The reproduction of the plateau pika (Ochotona curzoniae) was investigated in Guoluo District at an elevation of 4,000 m on the Qinghai–Tibetan plateau, China, from April 2007 to August 2008. Reproduction was seasonal, and the breeding season lasted from April to late June/early July.

Biogeographical Study of Plateau PikasOchotona curzoniae(Lagomorpha, Ochotonidae)

Zoological Science, 2012
We reconstructed the demographic history of the plateau pika (Ochotona curzoniae) on the Qinghai-Tibetan plateau by using genetic variation data obtained from spatially distributed populations across much of the plateau. We obtained sequence data, including cob (1,140 bp) and D-loop sequences (732 bp), from 144 individuals at sites ranging from the ...
