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

open access: yesGrassland 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‐

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

open access: yesFrontiers 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.

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

open access: yesEcology 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.

Effects of Qinghai-Tibetan Railway on the Genetic Differentiation of Plateau Pika (Ochotona curzoniae) Based on Cytochrome b Sequences [PDF]

open access: yes, 2012
Plateau pika (Ochotonidae: Ochotona curzoniae) is widespread in Qinghai-Tibetan Plateau (QTP). It is endemic to QTP and restricted to high altitude area, ranging from 3,000 to 5,200 m above sea level. In this study, I examined the genetic structure of O.

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

open access: yesMolecular 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.

Tissue Specific Expression of Plateau Pikas (Ochotona curzoniae   ) HIF-1α mRNA Under Normal Oxygen [PDF]

open access: yes, 2004
Hypoxia inducible factor 1 (HIF-1),which is a transcription factor composed of HIF-1α and arylhydocarbon nuclear receptor translocator (ARNT),plays an important role in the signal transduction of cell response to hypoxia.Plateau pikas (Ochotona ...

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

open access: yesFrontiers 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 ...

Enterotypes of the Gut Microbial Community and Their Response to Plant Secondary Compounds in Plateau Pikas

open access: yesMicroorganisms, 2020
Animal gut microbiomes can be clustered into “enterotypes” characterized by an abundance of signature genera. The characteristic determinants, stability, and resilience of these community clusters remain poorly understood.

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

open access: yesJournal 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.

Water, Wildlife and the World: A Global Synthesis of Trends in Wildlife Ecohydrology Research

open access: yesEcohydrology, Volume 18, Issue 7, October‐November 2025.
ABSTRACT Ecohydrology and hydroecology are interdisciplinary fields that examine the interactions between ecology and hydrology to address critical issues pertaining to both disciplines. However, the study of ‘ecology’ in ecohydrology research has largely focused on vegetation, leading to a gap in knowledge regarding direct relationships between ...
