项目摘要

This action funds an NSF Postdoctoral Research Fellowship in Biology for FY 2020, Broadening Participation of Groups Under-represented in Biology. The fellowship supports a research and training plan for the Fellow that will increase the participation of groups underrepresented in biology. To conserve biodiversity in a changing climate, it is important to understand how species respond to changing temperatures in both the short and long term. However, this task is not easy since temperature affects individuals in multiple ways, from molecules to ecosystems and in how they interact with other species. Recent scientific progress in genetics, evolutionary biology, ecology, and mathematical modelling makes possible a comprehensive approach to understanding how organisms respond to temperature increase. Just as this research takes a broad approach to address the effects of temperature on biological systems, it is necessary to take a broad approach to increase diversity in the field of biology. The fellow will focus this effort on increasing the participation of women of color, who are underrepresented in science. The fellow will combine laboratory experiments and mathematical models to investigate how increasing temperature alters individual and generational performance. Furthermore, this research will investigate how species interactions (via bacterial infection), and the type of spatial landscape, alter the ability to adapt to temperature changes. The experimental system is made up of two model species, a well-studied fruit fly and a bacterial pathogen that is widespread in humans and wild animals. The fellow will use data from this experimental system to parameterize a mathematical model of how temperature change alters species dynamics and extinction probability. Not only will this model be useful to aid in vulnerability assessments of natural species and communities of interest, it also will provide useful information about how temperature alters the virulence of a common pathogen of humans and wild animals. To support women of color in strengthening their science identities, the fellow will conduct high school, undergraduate and graduate student outreach. These actions include developing a module for use in the classroom to allow students to investigate the effect of temperature on biological communities. Furthermore, the fellow will develop a web-based international women’s mentoring chain, connecting scientists in Ecology and Evolution from seniors in high school to university professors.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该行动资助 2020 财年 NSF 生物学博士后研究奖学金，扩大生物学领域代表性不足群体的参与。该奖学金支持该研究员的研究和培训计划，该计划将增加生物学领域代表性不足的群体的参与。为了在气候变化的情况下保护生物多样性，了解物种如何在短期和长期内应对温度变化非常重要。然而，这项任务并不容易，因为温度以多种方式影响个体，从分子到生态系统以及它们与其他物种的相互作用。遗传学、进化生物学、生态学和数学模型方面的最新科学进展使得我们能够采用全面的方法来了解生物体如何响应温度升高。正如这项研究采用广泛的方法来解决温度对生物系统的影响一样，有必要采取广泛的方法来增加生物学领域的多样性。该研究员将把这项工作的重点放在增加有色人种女性的参与上，因为她们在科学领域的代表性不足。该研究员将结合实验室实验和数学模型来研究温度升高如何改变个人和世代的表现。此外，这项研究将调查物种相互作用（通过细菌感染）和空间景观类型如何改变适应温度变化的能力。该实验系统由两种模型物种组成，一种是经过充分研究的果蝇，另一种是广泛存在于人类和野生动物中的细菌病原体。该研究员将使用该实验系统的数据来参数化温度变化如何改变物种动态和灭绝概率的数学模型。该模型不仅有助于对自然物种和感兴趣的群落进行脆弱性评估，还将提供有关温度如何改变人类和野生动物常见病原体的毒力的有用信息。为了支持有色人种女性加强她们的科学身份，该研究员将开展高中、本科生和研究生的外展活动。这些行动包括开发一个在课堂上使用的模块，让学生能够研究温度对生物群落的影响。此外，该研究员还将开发一个基于网络的国际女性指导链，将生态学和进化论领域的科学家从高中生到大学教授联系起来。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
