Fossil pollen is an important tool for understanding biogeographical patterns in the past, but the taxonomic resolution of the fossil‐pollen record may be limited to genus or even family level. Chemical analysis of pollen grains has the potential to increase the taxonomic resolution of pollen analysis, but present‐day chemical variability is poorly understood. This study aims to investigate whether a phylogenetic signal is present in the chemical variations of Quercus L. pollen and to assess the prospects of chemical techniques for identification in biogeographical research.

栎属花粉中的化学变化作为分类学鉴定的工具：对长期生态和生物地理研究的启示

化石花粉是过去了解生物地理模式的重要工具，但是化石花粉记录的分类学解决方案可能仅限于属甚至家庭级别。花粉粒的化学分析有可能提高花粉分析的分类学分辨率，但是对当今的化学变异性了解甚少。这项研究的目的是调查是否在栎属花粉的化学变异中存在系统发生信号，并评估在生物地理学研究中鉴定化学技术的前景。
