Opposite companion effect on flight initiation distance in sympatric species: plateau pika (Ochotona curzoniae) and white-rumped snowfinch (Montifringilla taczanowskii) [PDF]

, 2015
There are many factors influencing prey’s risk perception and escape decision during predator-prey encounters. The distance at which animals move away from perceived danger (often quantified as flight initiation distance [FID]) has been used by ...

Evidence of Intraspecific Adaptive Variation in the American Pika (Ochotona princeps) on a Continental Scale Using a Target Enrichment and Mitochondrial Genome Skimming Approach

Molecular Ecology, Volume 34, Issue 20, October 2025.
ABSTRACT Montane landscapes present an array of abiotic challenges that drive adaptive evolution amongst organisms. These adaptations can promote habitat specialisation, which may heighten the risk of extirpation from environmental change. For example, higher metabolic rates in an endothermic species may contribute to heightened cold tolerance, whilst ...

Herbivorous mammals adjust their feeding patterns according to the abundance of available diet to adapt to the effects of grassland degradation

Global Ecology and Conservation
The degradation of grasslands on the Qinghai–Tibet Plateau has severely impacted the region’s ecology and productivity, subsequently affecting the dietary niche of the region’s herbivores.

高原鼠兔对极端低氧环境的生理、行为和分子生物学适应研究进展

野生动物学报, 2022
从生理学、行为学及分子生物学等方面对高原鼠兔（Ochotona curzoniae）的低氧适应机制进行阐述，发现高原鼠兔血液与血红蛋白的结合、释放氧的能力较高，这对低氧时体内氧的传递是有利的；肺小动脉壁变薄，这有利于在低氧条件下进行气体交换，使更多的氧进入肺部，同时高原鼠兔的右心室重量低于常氧环境中的大鼠。这就最大限度防止了高原鼠兔在低氧环境中出现右心室衰竭。行为学研究主要集中在其繁殖行为方面，分子生物学研究主要集中在其血管生成、能量代谢和携氧蛋白的携氧能力方面。

Preference for ground cover when selecting burrow entrances in plateau pikas

Ecology and Evolution
Burrow‐dwelling animals such as the plateau pika (Ochotona curzoniae) often seek sturdy entrances for their burrows, which can reduce the need for frequent maintenance.

Dietary Differentiation Mitigates Interspecific Interference Competition Between Sympatric Pallas’s Cats (Otocolobus manul) and Red Foxes (Vulpes vulpes)

Animals
The comparative analysis of the feeding ecology among sympatric small carnivores reveals both differentiation and overlap in resource utilization patterns, which serves as a critical pathway for understanding interspecific interactions and maintaining ...
