Understanding the importance of biological diversity is critical in the face of unprecedented, anthropogenic global change such as increased introduction of invasive species and land-use change. This research consists of two greenhouse experiments that will provide insight into how diversity is maintained in grasslands, and why this diversity could be important to ecosystem functions such as productivity and invasion resistance. The first experiment will establish competition among genetically distinct individuals to understand how diversity is maintained within a dominant native grass. The second experiment will examine how this genetic diversity prevents establishment of different native and invasive seedlings. Results from this project will inform the preservation of biodiversity, prevention of species invasions, and the enhancement of carbon sequestration in grasslands, an economically and ecologically valuable ecosystem. Results will also be integrated into local environmental education programs to emphasize the importance of preserving biodiversity in native ecosystems. The project will give undergraduate and underrepresented high school students access to hands-on learning about the research process, allowing them to connect scientific research on a growing environmental problem. Finally, funding this project will train a young female scientist.

面对前所未有的人为全球变化，例如增加入侵物种和土地利用变化，了解生物多样性的重要性至关重要。这项研究由两个温室实验组成，这些实验将提供有关草原多样性如何维持的洞察力，以及为什么这种多样性对生产力和耐药性等生态系统功能很重要。第一个实验将在遗传上不同的个体之间建立竞争，以了解如何在主要的本地草中维持多样性。第二个实验将研究这种遗传多样性如何阻止建立不同的天然和侵入性幼苗。该项目的结果将为生物多样性，预防物种入侵的保存以及在经济和生态上有价值的生态系统中增强碳固存。结果还将集成到当地的环境教育计划中，以强调保护本地生态系统中生物多样性的重要性。该项目将使本科生和代表性不足的高中学生可以访问有关研究过程的动手学习，从而使他们能够将科学研究联系起来，以了解不断增长的环境问题。最后，为这个项目提供资金将培训一位年轻的女科学家。
