报告内容简介：

　　DNA sequences are now widely employed to reconstruct not only the phylogenetic relationships of extant organisms but also to infer the historical processes involved in the unfolding of the tree of life. These studies have dramatically improved our understanding of the evolution of plant diversity since the colonization of land. Two interesting aspects are emerging from these studies. On one hand, evidence was found that major global climate fluctuations and/or geological events result in coinciding increases or declines of the diversification rates of several branches of life. On the other hand, some lineages show strong lineage specific responses to the same events. The origin of these contrasting patterns will be discussed on selected examples such as evolution of liverworts compared with the evolution of other land plants. Lineage specific issues will be further highlighted by exploring the impact of key-innovations and key-opportunities on the diversity of selected lineages of land plants. Finally, I will give an outlook on the future directions of this research in particular the impact of multi-gene analyses, integration of fossil evidence, and powerful bioinformatics.

　　通过主讲人的报告，让听众了解植物多样性分化和植物系统进化方面的最新研究进展。他的报告对我校植物学，生态学以及进化生物学等学科有重要的借鉴意义。
