This action funds an NSF Postdoctoral Research Fellowship in Biology for FY 2019, 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. This study examines how the diet of an animal can help it survive attacks from other animals. The Fellow studies the fall webworm, a caterpillar that eats the leaves of different trees. Fall webworms are attacked by parasitic insects that lay their eggs inside the caterpillar and use it as a host. The caterpillar's immune system can help defend against these parasitic insects, but the strength of the immune system can be affected by the caterpillar's diet. The Fellow uses experiments and field surveys in Colorado to understand whether different trees increase the immunity of the fall webworm against wasp attacks. The survival of insects, like many animals, is dependent on the plants in their habitat. As changes in climate transform many plant communities, insects are likely to be affected too. This study will increase understanding of how plant-insect interactions might change if major climatic events drastically modify plant communities. In addition, the Fellow works closely with youth from underrepresented minority students from urban areas in Denver. Students will participate in wildlife surveys, which increase awareness of wildlife. The fellow will also promote opportunities for mentorship and guidance by creating an online network of biologists from minority backgrounds who will advise high school students. For widely distributed animals, the relative importance of diet and natural enemies can vary depending on location and composition of ecological communities. The Fellow will use genomics to identify and quantify the diversity of parasitic insects attacking fall webworm across its range in Colorado. Next, the Fellow will use lab experiments to measure the relationship between diet and the nutrient quality of fall webworms. Finally, the Fellow will manipulate the caterpillar's diet to examine how different tree species impact the caterpillar's ability to launch immune defenses against parasitic insects. This research includes two approaches to increase interactions with nature among underrepresented minority students in urban public schools. First, the Fellow will use an experiential learning model to create interactive out-of-school learning opportunities for middle school students. Second, the Fellow will build an online network of professional biologists who agree to be mentors for high school students with interests in biology.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.

这项行动资助了2019财年的NSF生物学博士后研究奖学金，扩大了生物学中代表性不足的群体的参与。该研究金支持研究员的一项研究和培训计划，该计划将增加在生物学领域代表性不足的群体的参与。 这项研究探讨了一种动物的饮食如何帮助它在其他动物的攻击下生存下来。 研究员研究秋网虫，一种吃不同树叶的毛虫。 秋网虫受到寄生昆虫的攻击，寄生昆虫在毛虫体内产卵，并将其作为宿主。 毛虫的免疫系统可以帮助抵御这些寄生虫，但免疫系统的强度可能会受到毛虫饮食的影响。 该研究员在科罗拉多进行实验和实地调查，以了解不同的树木是否会增加秋网虫对黄蜂攻击的免疫力。 昆虫的生存，像许多动物一样，依赖于它们栖息地的植物。 随着气候变化改变许多植物群落，昆虫也可能受到影响。这项研究将增加了解如何植物-昆虫相互作用可能会改变，如果重大气候事件急剧改变植物群落。 此外，该研究员还与丹佛城市地区代表性不足的少数民族学生的青年密切合作。 学生将参加野生动物调查，提高对野生动物的认识。该研究员还将通过创建一个由少数族裔背景的生物学家组成的在线网络，为高中生提供指导和指导。对于广泛分布的动物，食物和天敌的相对重要性可能因生态群落的位置和组成而异。 该研究员将利用基因组学来确定和量化在科罗拉多的范围内攻击美国白蛾的寄生昆虫的多样性。接下来，研究员将使用实验室实验来测量饮食和秋网虫营养质量之间的关系。 最后，研究员将操纵毛虫的饮食，以研究不同的树种如何影响毛虫对寄生虫的免疫防御能力。 这项研究包括两种方法，以增加在城市公立学校中代表性不足的少数民族学生与自然的互动。首先，研究员将使用体验式学习模式，为中学生创造互动的校外学习机会。第二，该研究员将建立一个由同意成为对生物学感兴趣的高中生导师的专业生物学家组成的在线网络。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。
