Dissertation Research: Molecular and Morphological Analysis of Caryota (Palmae)

应用形态、解剖和DNA水平分析对棕榈属Caryota(Palmae)进行了生物系统学研究。该属是热带森林乔木的一个单系类群，具有经济、进化和生态重要性。由于以往分类中使用的许多形态特征的多样性，Caryota内的物种划分和Caryotoid属之间的系统发育关系并没有得到很好的解决。独立于描述形态和解剖学、几何形态计量学、叶绿体和核基因组限制性内切酶定位图以及孢粉学的数据集将接受各种系统发育分析，以努力为该属建立可靠的分类和专著，研究棕榈树内部的系统发育关系和不同的形态特征，研究颖果类棕榈树的分子进化模式，并探索该属内表达的生物地理和物种形成模式。

A biosystematic study of the genus Caryota (Palmae) using morphological, anatomical, and DNA level analyses is proposed. The genus is a monophyletic group of tropical forest trees with economic, evolutionary, and ecological importance. Due to the variability of many morphological characters used in previous taxonomies, species delimitions within Caryota and phylogenetic relationships among the caryotoid genera are not well resolved. Datasets, derived independently from several lines of inquire including descriptive morphology and anatomy, geometric morphometry, chloroplast and nuclear genome restriction endonuclease site mapping, and palynology will be subjected to a variety of phylogenetic analyses in an effort to establish a reliable taxonomy and monograph for the genus, examine phylogenetic relationships within and variable morphological characters within palms, examine patterns of molecular evolution in the caryotoid palms, and explore patterns of biogeography and speciation as expressed within the genus.
