The main goals of this proposal are to assess the evolutionary history of Colobanthus quitensis in Antarctica and southern South America by evaluating: (i) how its genetic diversity is distributed within and among populations, (ii) how historical processes have influenced the contemporary distribution of C. quitensis across its southern range of distribution, and (iii) whether geographical patterns of genetic variation are consistent with the diversity of microflora and their symbiotic effects. These predictions will be tested using experimental approaches as well as population genetic and phylogeographic analyses. This research proposal will shed fundamental new light on the evolutionary history of the flora between South America and the Antarctica.

该提案的主要目标是评估南极和南美南美洲的丘脑的进化历史，通过评估：（i）其遗传多样性如何在人群中和人群中分布，（ii）历史过程如何影响C. quitensis的当代分布在其南部的分布范围以及（iii II II II III）中的当代分布，以及（iii II II II II II II II）。共生效应。这些预测将使用实验方法以及种群遗传和植物地理分析进行测试。这项研究建议将为南美和南极洲之间的植物群的进化史提供基本的新启示。
