Piperales represent virtually the whole diversity of growth and life forms in angiosperms including herbs, shrubs, trees, parasites, epiphytes and climbers. This diversity is symptomatic for the success of Piperales in many ecosystems. Despite the importance of plant life and growth forms for ecosystem complexity and biodiversity, few studies have evaluated their evolutionary occurrence and patterns across major groups of angiosperms. This project aims at analyzing life and growth form evolution in the order Piperales, which represents the largest clade of basal angiosperms. The project will combine (i) biomechanical techniques with (ii) recent molecular phylogenetic approaches to study form traits and their evolution. Our main approaches are (1) identifying essential biomechanical and hydraulic traits e.g. fiber production, secondary growth as well as stem rigidity/flexibility and conductivity in different forms, and (2) to observe how these traits and forms are distributed across taxa in the Piperales using a variety of phylogenetic methods.

被子植物目几乎代表了被子植物包括草本、灌木、乔木、寄生植物、附生植物和攀缘植物的生长和生活形式的全部多样性。这种多样性是许多生态系统中的成功的征兆。尽管植物生命和生长形式对生态系统复杂性和生物多样性的重要性，但很少有研究评估它们在被子植物主要类群中的进化发生和模式。该项目旨在分析代表基底被子植物最大分支的被子植物目的生活和生长形式进化。该项目将结合联合收割机（i）生物力学技术（ii）最近的分子系统发育方法来研究形式特征及其进化。我们的主要方法是（1）确定基本的生物力学和水力性状，如纤维生产，次生生长以及茎的刚性/柔韧性和传导性在不同的形式，和（2）观察这些性状和形式是如何分布在不同的类群中，在被子植物中使用各种系统发育方法。
