Identifying Conservation and Conflict Zones for Tibetan Brown Bears Under Climate Change Through Integrated Habitat and Prey Modeling on the Qinghai-Tibet Plateau. [PDF]

Ecol Evol
This study evaluates the future habitat dynamics of the Tibetan brown bear on the Qinghai‐Tibet Plateau under climate change by integrating predator–prey relationships and environmental variables using the MaxEnt model. Results show significant habitat contraction and shifting patterns, increasing the risk of human‐bear conflict.

Habitat Utilization Preference by Small Mammals Is Associated With Geomorphic and Soil Properties: A Case Study of the Plateau Pika From the Eastern Qinghai‐Tibet Plateau [PDF]

Ecol Evol
This study, through a large‐scale survey, reveals a close relationship between plateau pika habitat use preferences and geomorphic and soil characteristics. The findings indicate that pikas prefer flat, sun‐facing terrain near water sources, as well as specific ranges of soil depth, organic matter, and moisture.

Summer habitat use of plateau pikas (Ochotona curzoniae) in response to winter livestock grazing in the alpine steppe Qinghai-Tibetan Plateau

Arctic, Antarctic, and Alpine Research, 2018
Plateau pikas (Ochotona curzoniae), burrowing lagomorphs endemic to the Qinghai-Tibetan Plateau (QTP), are considered pests by Chinese authorities because of their association with grasslands that are characterized as degraded.

Late summer plateau pika spatial habitat use revealed by high‐resolution wildlife tracking and unmanned aerial vehicle data on the Qinghai–Tibet Plateau

Grassland Research
Background The Qinghai–Tibet Plateau has significant grassland degradation. The plateau pika (Ochotona curzoniae Hodgson), a small burrowing mammal, traditionally viewed as a pest, may strongly shape vegetation, yet its fine‐scale spatial ecology remains

Shiga Toxin-Producing Escherichia coli in Plateau Pika (Ochotona curzoniae) on the Qinghai-Tibetan Plateau, China [PDF]

Frontiers in Microbiology, 2016
Shiga toxin-producing Escherichia coli (STEC) are an emerging group of zoonotic pathogens. Ruminants are the natural reservoir of STEC. In this study we determined the prevalence and characteristics of the STEC in plateau pika (Ochotona curzoniae) on the

Sex-Based Dietary Divergence in Plateau Pikas (Ochotona curzoniae) but Not Plateau Zokors (Eospalax baileyi) [PDF]

Animals
Quantifying sex-specific dietary differences in small mammals reveals the internal resource allocation mechanisms within a species and provides new insights for ecosystem management and conservation practices.

The Utilization of Artificial Burrows by Plateau Pikas Under Rapid Vegetation Restoration. [PDF]

Ecol Evol
Vegetation changes often elicit adaptive responses in herbivores. Plateau pikas do not prefer to cope with rapid vegetation changes by adjusting the use of spatial resources. Instead, burrow accessibility and scent‐marking potential—driven by morphological preferences—are the primary determinants shaping their spatial resource selection.

Spatiotemporal Distribution Patterns of Plateau Foxes and Their Lagomorph Prey in Baqing County, Tibet. [PDF]

Ecol Evol
Our study suggests pronounced spatiotemporal niche differentiation as a mechanism facilitating two mesocarnivores' coexistence, and enhances our understanding of the mechanisms underlying sympatric coexistence on the Tibetan Plateau. ABSTRACT Predation by carnivores is a fundamental driver of species evolution, shaping interspecific spatiotemporal ...

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 [PDF]

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.

Differences in Dietary Composition and Interspecific Competition Among Large Carnivores on the Qinghai-Xizang Plateau. [PDF]

Ecol Evol
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 ...
