Leaf morphological data of oak species from two sampling sites

This study investigated leaf phenotypic variation in oak species to better understand how different groups of oaks adapt to diverse environmental conditions. We examined the leaf phenotypic traits of six oak populations in two mixed forests with differing species compositions: Zijin Mountain in Jiangsu Province, composed of Quercus acutissima, Q. variabilis, and Q. fabri; and Youhua Village in Anhui Province, consisting of Q. acutissima, Q. chenii, and Q. fabri. The results indicated that species in the Cerris group (Q. acutissima, Q. chenii, Q. variabilis) exhibited stable leaf morphology and higher fluctuating asymmetry (FA), suggesting adaptation to stable environments. In contrast, Q. fabri from the Quercus group showed higher phenotypic plasticity and lower FA, indicating a strategy for adapting to dynamic environments. The study also explored the relationship between FA and phenotypic plasticity, revealing that while both..., , , # Leaf Phenotypic Data from Two Sampling Sites: Open Source Data

We have submitted two CSV files. One contains the leaf phenotypic data of oak individuals collected from Youhua village (YH.CSV), and the other contains the leaf phenotypic data of oak individuals collected from Zijinshan mountain (ZJ.CSV).
