高原鼠兔（Ochotona curzoniae）的生态功能

野生动物学报, 2013
高原鼠兔作为青藏高原上广泛分布的小型穴居植食性哺乳动物受到了人们的广泛关注。其植食性特点和挖掘活动对高寒草地植被、生物多样性、物质循环等方面具有重要影响,但这种影响对青藏高原草地生态系统的利弊还存在较大争议。一方面认为,高原鼠兔可提高栖息地植被的丰度;维持生态系统的多样性,为捕食者提供食物资源,也为许多其他动物提供栖息地;同时,其挖掘活动会对土壤产生扰动,增加土壤的渗透力和含水量,促进物质循环。另一方面,有学者认为,高原鼠兔会破坏植物根系和土壤结构,加快土壤的侵蚀速度,降低栖息地的植被质量 ...

Transformative changes of pastoral livestock production and its consequences on the Qinghai–Xizang Plateau

Grassland Research, Volume 5, Issue 1, Page 35-43, March 2026.
Grassland functional zoning and spatial optimization scheme on the Qinghai–Xizang Plateau. Based on multifunctionality assessment, the scheme proposes allocating 32% of regional grassland as nature reserve grasslands (biodiversity focus), 63% as livestock grazing grasslands (smart ecological–production management), and 5% as cultivated grasslands (high‐

Differences in Dietary Composition and Interspecific Competition Among Large Carnivores on the Qinghai–Xizang Plateau

Ecology and Evolution, Volume 16, Issue 2, February 2026.
This study elucidated the mechanisms underlying regional coexistence among the snow leopard (Panthera uncia), wolf (Canis lupus), and brown bear (Ursus arctos) through the analysis of their trophic niches. The findings provide a scientific foundation for further investigation into the mechanisms that maintain carnivore communities in high‐altitude ...

Pika population density is associated with composition and diversity of gut microbiota

Frontiers in Microbiology, 2016
Host population density is positively associated with the strength of social interactions or the frequency of physical contacts, and thus potentially influences microbial transmission among individuals.

Response of Plant Phylogenetic Structure to Plateau Pika ( Ochotona curzoniae ) Disturbance on Alpine Meadow of Qinghai‐Tibetan Plateau

Land Degradation & Development
Plant community construction is influenced by bottom‐up processes, such as environmental factors, and top‐down processes, such as herbivore disturbances.

Hibernation Shifts in Gut Microbiota Composition and Metabolic Function in the Chinese Horseshoe Bat (Rhinolophus sinicus)

Ecology and Evolution, Volume 16, Issue 2, February 2026.
The composition and dynamics of gut microbial community structure in Rhinolophus sinicus, employing 16S rRNA amplicon sequencing, are conducted to investigate the effects of physiological status (winter hibernation versus summer activity) on gut microbiota composition.

Biogeography and Climate Drive Population Divergence and Genomic Vulnerability in High Altitude Endemic Bird

Molecular Ecology, Volume 35, Issue 4, February 2026.
ABSTRACT High‐elevation systems support species adapted to extreme conditions, and their rugged terrain and variable microclimates strongly shape evolution and persistence. Yet few studies have evaluated how geography and climate jointly shape genetic diversity, local adaptation and vulnerability to environmental change.

Diet diversity is associated with beta but not alpha diversity of pika gut microbiota

Frontiers in Microbiology, 2016
Wild mammals often consume different food sources as they become geographical available. This change in diet composition is likely to influence the gut microbial community, yet it remains unclear what the relationship looks like—particularly in small ...

Habitat-induced changes in forage quality and implications for fitness in Plateau Pika (Ochotona curzoniae)

Journal of Mammalogy
Plateau pikas (Ochotona curzoniae) play a keystone role in the alpine meadow ecosystem on the Qinghai–Tibetan Plateau (QTP). For decades, QTP grasslands have become degraded to some degree, largely as a result of heavy livestock grazing.
