REU Site: University of Michigan Biological Station: Biosphere-Atmosphere-Hydrosphere Interactions in a Changing Global Environment

密歇根大学生物站的这个REU站点将让学生参与研究，研究几乎所有生态系统现在都如何受到全球变化驱动因素的影响，例如气温上升、降水变化、土壤湿度变化、大气中二氧化碳和臭氧水平的增加、活性氮的沉积、入侵物种和栖息地的丧失。多个全球变化驱动因素通常相互作用；例如，气温上升可能与臭氧水平上升协同作用，以阻碍陆地碳储存，并与土壤水分减少和大气氮沉积增加相互作用，以促进入侵动植物物种的传播。人们对生物圈-大气-水圈的相互作用知之甚少，但它们是全球变化科学的重要组成部分。因此，非常重要的是培养有前途的年轻研究人员，以确定和量化这些相互作用，以便它们最终可能有助于解决21世纪日益复杂的环境问题。密歇根大学生物站(UMBS)这一跨学科REU项目的最终目标是培养年轻科学家进入研究事业，研究全球变化的大气、水文和生态原因和后果。该计划通过密集指导的个人研究项目、生物地球化学、大气化学、全球变化、生态学、实验设计和统计、职业道德和交流、每周生物圈-大气-水圈阅读小组和参加密歇根大学商学院的研究研讨会提供全面的培训。该计划强调REU学生积极参与高质量研究的所有阶段，从假设形成到以口头和书面形式展示结果。招聘工作将扩大，包括与代表性不足的少数族裔服务机构和STEM研究机会有限的机构建立更多合作伙伴关系(包括教师的现场存在)，在UMBS举行招聘活动，并支持以前的REU学生担任该项目的学生大使。

This REU Site at University of Michigan Biological Station will engage students in research that examines how virtually all ecological systems are now being influenced by global change drivers such as rising temperatures, altered precipitation, altered soil moisture, increasing levels of atmospheric CO2 and ozone, deposition of reactive nitrogen, invasive species, and habitat loss. Multiple global change drivers typically interact with one another; for instance, rising temperatures may interact synergistically with increasing ozone levels to impede terrestrial carbon storage, and with reduced soil moisture and increased atmospheric nitrogen deposition to facilitate the spread of invasive plant and animal species. Such biosphere-atmosphere-hydrosphere interactions are poorly understood, but are crucial components of global change science. It is therefore very important to train promising young researchers to identify and quantify these interactions in order that they may ultimately help solve the increasingly complex environmental problems of the 21st century. The ultimate goal of this interdisciplinary REU program at University of Michigan Biological Station (UMBS) is to nurture young scientists to enter research careers addressing atmospheric, hydrological, and ecological causes and consequences of global change. The program provides comprehensive training via intensively mentored individual research projects, workshops in biogeochemistry, atmospheric chemistry, global change, ecology, experimental design and statistics, professional ethics, and communication, a weekly biosphere-atmosphere-hydrosphere reading group, and attendance at UMBS research seminars. The program emphasizes active participation by REU students in all phases of high quality research, from hypothesis formation through presentation of results in oral and written formats. Recruitment efforts will be expanded to include more partnerships with Underrepresented Minority Serving Institutions and institutions with limited opportunities for STEM research (including an on-site presence of faculty), a Recruiting Event at UMBS, and support for prior REU students to act as student ambassadors for the program.
