项目摘要

Hyperdiversification (extraordinarily high species diversity) is found in several animal groups, but its origins are not well understood. In this project, the investigators will produce a phylogeny of the diving beetles (Dytiscidae, 4200 known species) and investigate correlations between evolutionary origins of reproductive strategies and species diversification. The group is important as predators in aquatic systems and as food for both aquatic and terrestrial insectivores. The research will investigate coevolution of female reproductive tracts, sperm, and mating behaviors in a phylogenetic context to discover correlations and their contribution to hyperdiversification. Understanding the different impacts of traits on speciation should lead to a better understanding of species radiations that are not due to ecological changes.This project will train both graduate students and undergraduates in species origins and diversification, phylogenetic analysis, coevolution and evolutionary theory, and the factors involved in these processes. The institution is a minority serving university and students from underrepresented groups in science will gain training in STEM fields. A course will be developed based on this project and material will be disseminated through publicly accessible web sites for researchers, educators and students.

在几个动物群体中发现了高度多样化（非常高的物种多样性），但其起源尚不清楚。在这个项目中，研究人员将产生一个潜水甲虫（Dytiskiatae，4200已知物种）的进化史，并调查生殖策略的进化起源与物种多样化之间的相关性。这类动物是水生系统中的重要捕食者，也是水生和陆生食虫动物的食物。该研究将调查女性生殖道，精子和交配行为在系统发育背景下的共同进化，以发现相关性及其对过度多样化的贡献。本计画将针对研究生与本科生进行物种起源与多样性、系统发育分析、共同进化与进化理论、以及这些过程所涉及的因素等方面的训练。该机构是一个少数服务的大学和学生从科学代表性不足的群体将获得在STEM领域的培训。将根据这一项目编制一个课程，并将通过研究人员、教育工作者和学生可公开访问的网站传播材料。
