项目摘要
The origin of species remains an especially difficult problem in biology because the processes through which reproductive barriers arise between diverging populations remain poorly understood. This project will advance understanding of the origins of diverse tropical plant taxa through study of the nature of reproductive barriers in Metrosideros, a highly diverse genus of tropical forest trees that vary in their degree of divergence and isolation. This project will integrate molecular genetic methods and field experiments to determine the nature and degree of pre- and post-zygotic barriers to hybridization between co-occurring taxa at sites that vary in rates of natural hybridization. This research will provide insight into the speciation process in long-lived forest trees, a group that is responsible, directly or indirectly, for much of the high diversity of tropical forest ecosystems. This CAREER project integrates research and education to promote scientific literacy and skills at all levels of the education pipeline in one of the most culturally diverse regions of the U.S. The project will engage students from underrepresented groups in the STEM pipeline, which will broaden the career choices for these individuals while helping to advance the diversity of the science and technology workforce. The project includes development of graduate and undergraduate courses that include authentic research experiences, mentoring of undergraduate and graduate students, and outreach to K-12 teachers and students.
物种的起源在生物学中仍然是一个特别困难的问题,因为在不同种群之间产生繁殖障碍的过程仍然知之甚少。本项目将通过对热带森林树木中具有高度多样性、分化程度和隔离程度不同的Metrosideros属的生殖屏障性质的研究,促进对不同热带植物分类群起源的理解。该项目将整合分子遗传学方法和野外实验,以确定在自然杂交率不同的地点共同发生的分类群之间的杂交前和杂交后障碍的性质和程度。这项研究将提供对长寿森林树木物种形成过程的深入了解,这一群体直接或间接地对热带森林生态系统的高度多样性负责。这个CAREER项目将研究和教育结合起来,在美国文化最多样化的地区之一的各级教育管道中提高科学素养和技能。该项目将吸引来自STEM管道中代表性不足的群体的学生,这将拓宽这些人的职业选择,同时有助于促进科技劳动力的多样性。该项目包括研究生和本科生课程的开发,其中包括真实的研究经验,本科生和研究生的指导,以及对K-12教师和学生的推广。
