海拔梯度筛选种子性状与萌发策略的东部藏高原研究数据

本数据集记录了青藏高原东部草原海拔梯度上采集的408种被子植物种子的形态与萌发性状。数据包含物种水平及22个跨海拔分布物种的种内性状变化，用于检验海拔对种子性状的过滤效应，探索其对群落构建和物种分布的影响。

This dataset records morphological and germination traits of seeds from 408 angiosperm species sampled along elevational gradients in the grasslands of the eastern Qinghai-Tibet Plateau. The data include both species-level trait data and intraspecific trait variation for 22 species with wide elevational distributions, and are used to test the filtering effect of elevation on seed traits, as well as to investigate their impacts on community assembly and species distribution.
