plateau pika keystone species

They look like round balls of fluff about 6 inches long with prominent round ears and a small tail hidden under their fur. Pika pet animal chinese red real. The small, burrowing pika — a relative of the rabbit — was discovered to have an oversized impact on shaping ground water penetration and surface flooding along the Tibetan plateau. Ochotona curzoniae. Two species reside in North America, the rest being found primarily throughout Central Asia; 23 of them live entirely or partly in China, especially the Tibetan plateau.There are two distinctly different ecological niches occupied by pikas. Plateau Pikas are one of the 30 species of pika worldwide. There are several uncertainties existing in the ecological behavior of the plateau pika and its impact on the alpine grasslands, and this impact has long been a subject under discussion. The plateau pika (Ochotona curzoniae) is a keystone species in the alpine rangeland ecosystem of the Qinghai–Tibetan Plateau. Appropriate population density of plateau pika could promote forage growth and maintain the ecosystem stability as an allogenic engineer [9,10]. Because the plateau pika shapes the successional direction of alpine meadows, it is commonly considered as a keystone species for alpine meadow ecosystems in the Qinghai-Tibetan plateau (Smith and Foggin, 1999, Lai and Smith, 2003, Guo et … A.T. Smith, J.M. classified as a keystone species and an ecosystem engineer on the QTP [3,6]. A dominant feature of their ecology is the burrows they construct. Conserv., 2 (1999), pp. The Plateau Pika: A Keystone Engineer on the Tibetan Plateau by Brigitte Wieshofer Hogan A Dissertation Presented in Partial Fulfillment ... dog as a keystone species (Kotliar et al. earthwatch(1/1/1999 - 12/31/2000). Emily T. Yeh Cultural Geographies. On the one hand, pika is considered a keystone species. Pests, keystone species, and hungry ghosts: the Gesar epic and human-pika relations on the Tibetan Plateau. the viewpoint that plateau pika was a keystone species or at least allogenic engineer in 327 alpine ecosystem in 21 century after a review paper by Smith and Foggin (1999) The plateau pika (Ochotona curzoniae) is a keystone species for biodiversity on the Tibetan plateau, Anim. As an example of these control efforts, during the past four decades the plateau pika has been poisoned cumulatively over 80,000 sq mi (200,000 sq km) in Qinghai Province, China. Colonies of over 300 individuals/ha have been reported. 1. Most previous studies of habitat selection by plateau pika have been conducted at a local microhabitat scale; however, little is known about the relationship between the distribution of plateau pika and macrohabitat factors at broad spatial scales. Practically, the population density of plateau pika is an important index for evaluating its ecological function [7,8]. 2019). Plateau pikas are considered a keystone species because of their pivotal role in the community dynamics of high‐altitude grasslands (Smith & Foggin 1999). In this study, we combine genetic and field data to character the population genetic pattern and dispersal dynamics in plateau pika (Ochotona curzoniae). The highly-social plateau pika (Lagomorpha: Ochotona curzoniae) excavates vast burrow complexes in alpine meadows on the Tibetan Plateau. The plateau pika is a keystone species on the Tibetan Plateau. fects of plateau pika (Ochotona curzoniae, hereafter pika) on alpine grassland on the Qinghai-Tibet Plateau (QTP).
