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。

Simulation and response mechanism of potential geographical distribution of plateau pika Ochotona curzoniae under climate change

Global Ecology and Conservation
With global warming, climate change had significant impacts on the distribution of species and their habitats. As one of the keystone species of the Qinghai-Tibet Plateau (QTP), the plateau pika Ochotona curzoniae plays a vital role in the alpine ...

Ecological threshold and the mechanisms of plateau pika (Ochotona curzoniae) bioturbation regulating ecosystem multifunctionality and stability

Ecological Indicators
Plateau pika (Ochotona curzoniae, hereafter pika) is a keystone species and allogenic engineer on the Qinghai-Tibet Plateau (QTP). However, excessive pika density adversely affects alpine grasslands.

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 ...

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

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.
