PYI: Processes and Consequences of Natural Selection in Plants

野生植物物种自然选择的过程和结果将在三个具体和互补的研究项目中进行。首先，研究了塞拉利昂东部几种同域野生植物种群内和种群间生活史和生殖性状变异的原因及其进化意义。另一个项目将继续进行正在进行的野生萝卜遗传参数估计（遗传能力和遗传相关性）的恒常性实验研究，其中将操纵生长条件，以评估在不同环境条件下进化的速度和方向。第三个项目将涉及确定种子传播和传播后事件作为秘鲁雨林中具有重要经济意义的树种分布的决定因素的相对重要性的工作。

The process and consequences of natural selection in wild plant species will be pursued in three specific and complementary research projects. In the first, the causes and evolutionary significance of variation in life history and reproductive traits within and among different populations of several sympatric wild plant species in the eastern Sierra Mountains will be investigated. Another project will continue ongoing experimental studies of the constancy of genetic parameter estimates (heritability and genetic correlation) in wild radish in which growing conditions will be manipulated to evaluate the rate and direction of evolution under diverse environmental conditions. The third project will involve work to establish the relative importance of seed dispersal and post-dispersal events as determinants of the species distributions of economically important trees in a Peruvian rainforest.
