The ancient genus Selaginella can reveal how natural selection shaped fundamental traits of plant reproduction like morphological differentiation of spores (a prerequisite for the evolution of seeds) and sexual division of reproductive investment. However, almost nothing is known of the ‘ecological theatre’ in which Selaginella evolves. This project will examine the worldwide phylogenetic pattern of reproductive traits in the genus, and combine field and greenhouse studies of Australian and Malaysian species in order to test fundamental ideas in evolutionary ecology such as the theory of sex allocation, and begin to establish the ecological and adaptive counterpart to Selaginella’s emerging role as a genomic model organism.

古老的卷柏属可以揭示自然选择如何塑造植物繁殖的基本特征，如孢子的形态分化（种子进化的先决条件）和生殖投资的性别划分。然而，几乎没有什么是已知的'生态剧场'中卷柏演变。本计画将检视世界范围内卷柏属生殖性状的系统发育模式，并结合联合收割机对澳大利亚和马来西亚物种的田间和温室研究，以测试演化生态学的基本概念，如性别分配理论，并开始建立生态学和适应性对应物，以配合卷柏作为基因组模式生物的新兴角色。
