This action funds an NSF Postdoctoral Research Fellowship in Biology for FY 2021, Integrative Research Investigating the Rules of Life Governing Interactions Between Genomes, Environment and Phenotypes. The fellowship supports research and training of the Fellow that will contribute to the area of Rules of Life in innovative ways. Development involves growth of the body and differentiation into specialized tissues. In response to early-life stress, organisms - from plants to insects to mammals - face trade-offs between developmental speed and specialization. Maturing at a faster rate may help organisms escape environmental stress but creates trade-offs with other traits that are important for survival such as body size, limb formation, and immune-system function. This research explores how accelerated growth impacts neural and cognitive development, which is critical for animals to accurately respond to beneficial cues and threats in their environments. Since developmental pathways and decision-making brain regions are shared across vertebrates, the Fellow’s research will be a major step forward for identifying mechanisms that mediate trade-offs between growth and differentiation. The Fellow will develop new, web-based activities to distribute material to a diverse audience and work with Native American students to incorporate frog-centric narratives that lend cultural and historical relevance to lesson plans. The Fellow will build networks across two research labs at Utah State University (USU) and the University of Illinois Urbana-Champaign to examine if sensory and cognitive phenotypes in anurans are stable or flexible in response to accelerated development. The Fellow will manipulate developmental timing in three distantly-related species of anurans to assess trade-offs in morphology, locomotion, sensory perception, and cognition, and then link trade-offs to underlying neuromolecular mechanisms and gene-expression patterns. This research will reveal how developmental plasticity manifests across levels of biological organization, how these patterns evolve or are maintained across diverse taxa, and how these phenomena influence the resiliency of species and communities to ecosystem changes. An additional component of the project is expansion to northern Utah K-12 schools by the Froggers School Program which brings hands-on, question-based learning experiences to local classrooms. The Fellow will also partner with established programs that specialize in student retention, completion, and inclusion at USU by mentoring students in undergraduate-led research and outreach projects that match students’ career goals.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2021财年NSF生物学博士后研究奖学金，研究基因组，环境和表型之间相互作用的生命规则的综合研究。该奖学金支持将以创新方式为《生活规则》领域作出贡献的研究员的研究和培训。发育包括身体的生长和分化成专门的组织。为了应对生命早期的压力，生物——从植物到昆虫再到哺乳动物——面临着在发育速度和专业化之间进行权衡的问题。以更快的速度成熟可能有助于生物体摆脱环境压力，但也会与其他对生存至关重要的特征（如体型、肢体形成和免疫系统功能）进行权衡。这项研究探讨了加速生长如何影响神经和认知发展，这对于动物准确响应环境中有益的线索和威胁至关重要。由于发育途径和决策脑区在脊椎动物之间是共享的，该研究员的研究将是确定调节生长和分化之间权衡的机制的重要一步。该研究员将开发新的网络活动，向不同的受众分发材料，并与美洲土著学生合作，将以青蛙为中心的叙述融入到课程计划中，使其具有文化和历史意义。该研究员将在犹他州立大学（USU）和伊利诺伊大学厄巴纳-香槟分校的两个研究实验室之间建立网络，以检查anurans的感觉和认知表型是稳定的还是灵活的，以响应加速发展。该研究员将操纵三个远亲物种的无脊椎动物的发育时间，以评估形态、运动、感觉知觉和认知方面的权衡，然后将权衡与潜在的神经分子机制和基因表达模式联系起来。本研究将揭示发育可塑性如何在生物组织的各个层面上表现出来，这些模式如何在不同的分类群中进化或维持，以及这些现象如何影响物种和群落对生态系统变化的弹性。该项目的另一个组成部分是通过Froggers学校计划将其扩展到犹他州北部的K-12学校，该计划为当地教室带来了动手，基于问题的学习体验。该研究员还将与USU的现有项目合作，专门研究学生的保留、完成和融入，指导学生进行本科生主导的研究和推广项目，以符合学生的职业目标。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
