Stevens0738118This award will support a Doctoral Dissertation Enhancement Project for Doctoral Student Felipe Zapata working with his advisor Peter Stevens. The research objectives of project are to identify and delimit the species in the plant genus Escallonia, and to reconstruct their evolutionary history using multivariate analyses of morphological measurements taken from herbarium specimens, combined with phylogenetic analyses of sequences from chloroplast and nuclear markers. Morphological and molecular patterns will be integrated with temporal (e.g., node dating), ecological (e.g., field data), and geographic (e.g., geographic barriers) variables to shed light on the historical biogeography of the genus and to suggest potential mechanisms for its diversification. Research in Brazil will be studied in collaboration with Dr. Lucia G. Lohmann from the department of Botany at the University of Saõ Paulo, in Saõ Paulo, Brazil.

这一奖项将支持博士生菲利佩·萨帕塔与他的导师彼得·史蒂文斯合作的博士论文增强项目。该项目的研究目标是通过对植物标本的形态测量进行多变量分析，结合叶绿体和核标记序列的系统发育分析，识别和划定海鞘属植物的物种，并重建它们的进化史。形态和分子模式将与时间(例如节点测年)、生态(例如现场数据)和地理(例如地理障碍)变量相结合，以阐明该属的历史生物地理并提出其多样化的潜在机制。巴西的研究将与巴西萨罗保罗大学植物学系的露西亚·G·罗曼博士合作进行。
