#PLATEAU PIKA PROFESSIONAL#

Given its burrowing and gnawing activities to plants, soils and competition with livestock for food, the plateau pika is often considered as a pest in alpine ecosystems (Smith and Foggin, 1999, Wei et al., 2020). The quadcopter is an efficient and economic tool for long-term repeated monitoring over large regions for further understanding the role of pika. The plateau pika (Ochotona curzoniae) is a common small mammal that inhabits on the Tibetan Plateau, China (Guo et al., 2012). Pika burrows and the burrowing-induced bare grounds usually co-existed, and the bare grounds that created by plateau pikas were easily to distinguish. We concluded that the direct burying and grazing effects of pika on alpine grassland were minor in this region. Plateau pika (Ochotona curzoniae) is the major ground-dwelling small mammalian herbivores in this region and is distributed widely in both types of alpine vegetation (Fig. Results showed that (1) the effects of pika pile burying on the reduction of vegetation cover, biomass, soil carbon, and nitrogen were less than 10 %, which was much smaller than the effects of bald patches and (2) pika consumed 8–21 % of annual net primary production of grassland. A plateau pika in Zadoi County of the Yushu Tibetan Autonomous Prefecture, northwest China's Qinghai Province. Living in the most hostile environment, the pika has to confront more than one predator. Plateau pika evolved with the uplifting of the Tibetan Plateau (Yu et. The plateau pika is a rabbit-like mammal dwelling on the Qinghai-Tibet Plateau between 3,000 meters to 5,000 meters above sea level.

Leptin, Brown Adipose Tissue and Energy Expenditure ResearchGate, the professional network for scientists. In August, population densities may range from 100 to 400 pikas ha1 (Liu et al., 1982). Altogether 168 plots were set on four different types of alpine grassland in a semiarid basin on the QTP. Plateau pika (Ochotona curzoniae), an endemic and. In this study, we investigated the direct effects, i.e., burying and grazing, of pika by upscaling field sampling at a quadrat scale to a plot scale ( ∼ 1000 m 2) by aerial photographing.

foxes are a little-studied species that live on the high Tibetan Plateau. Although significant efforts have been made to study the effects of pika at a quadrat scale ( ∼ m 2), our knowledge about its distribution and effects at a larger scale is very limited. once roamed Mediterranean islands, hunting small prey like birds and pika. On the one hand, pika is considered a keystone species. There is considerable controversy about the effects of plateau pika ( Ochotona curzoniae, hereafter pika) on alpine grassland on the Qinghai-Tibet Plateau (QTP).
