西藏自治区红尾沙蜥分布、形态、生理和生活史特征数据（2022）

以对环境变化极为敏感的外温脊椎动物——青海沙蜥为代表，子课题（2019QZKK05010216）通过野外调查，比较青藏高原及邻近地区不同海拔青海沙蜥种群的形态、生理和生活史的差异，分析青海沙蜥对青藏高原环境变化的响应和适应特征，结合物种分布模型（SDM）和机制模型预测青海沙蜥未来的受胁程度。本数据集包含1个信息表，记录在申扎、那曲、纳木措、安多测定的20个红尾沙蜥形态数据，信息表包含地点、性别、体重、头体长、腹长、头长、头宽等数据。

Taking the highly environment-sensitive ectothermic vertebrate *Phrynocephalus vlangalii* (Qinghai toad-headed agama) as the representative research subject, subproject (2019QZKK05010216) conducted field surveys to compare the variations in morphology, physiology and life history among its populations at different elevations across the Tibetan Plateau and its adjacent regions. This study analyzed the response and adaptive traits of *Phrynocephalus vlangalii* to environmental changes on the Tibetan Plateau, and integrated Species Distribution Model (SDM) and mechanistic models to predict the future threat level of this species. This dataset includes one information table, which documents morphological data from 20 *Phrynocephalus erythrurus* (Red-tailed toad-headed agama) individuals measured at Shenzha, Nagqu, Namtso and Amdo. The information table contains columns such as sampling location, sex, body weight, snout-vent length, abdominal length, head length and head width.
