This action funds an NSF Postdoctoral Research Fellowship in Biology for FY 2022, 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. Animals have evolved behaviors and morphologies to attract mates. These traits are often extreme and elaborate, from deer horns and beetle tusks to bird songs and spider dances. Yet, it is not entirely clear how these traits emerge and diversify. This project will leverage a rapidly evolving mate-attraction signal in crickets to understand the physics, physiology, and evolution of these traits. This study will provide novel and pressing insight into how some of nature’s most charismatic traits evolve in real time. The fellow will amplify their societal impact by developing evolution games for K-12 classrooms, mentoring undergraduates and high schoolers from underrepresented groups, and establishing digital infrastructure for scientists to transparently and equitably recruit undergraduate researchers at the University of Denver. This will promote equity in STEM by reducing the social capital required to attain undergraduate research positions.The fellow will integrate computational and experimental tools to elucidate the mechanisms and mechanics of signal evolution in the Hawaiian field cricket, Teleogryllus oceanicus. Field crickets sing intense pure-tone songs. In Hawaiian populations, a lethal parasitoid fly (Ormia ochracea) eavesdrops on singing male crickets, imposing a massive fitness cost. This push-and-pull of naturally selected costs (parasitism) and mating selected benefits have driven the evolution of novel signals that allow covert communication. Indeed, within the last few years, a novel purring cricket morph evolved that attracts female conspecifics but not parasitoid flies. The fellow will 1) perform artificial selection experiments to quantify the genetic architecture of song structure and female preference, 2) build finite element models to determine how acoustic biomechanics generate novel song features, 3) perform physiological assays to test sensory capabilities in females and parasites, and 4) build agent-based models to test how songs evolve as different selection pressures vary. The fellow will receive training from experts in evolutionary biology, psychoacoustics, and biophysics from the University of Denver, St. Olaf College, and the University of Western Ontario (Canada). The fellow will also develop K-12 educational tools, mentor high school and undergraduate research, and establish lasting infrastructure to promote equity and transparency in undergraduate research opportunities at the University of Denver.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.

该行动为2022财年的生物学生物学研究金提供了一项NSF博士后研究奖学金，该研究研究了研究基因组，环境和表型之间相互作用的生活规则。奖学金支持对研究员的研究和培训，这些研究和培训将以创新的方式为生活规则做出贡献。动物具有进化的行为和形态以吸引伴侣。这些特征通常是极端和精致的，从鹿角和甲虫象牙到鸟类的歌曲和蜘蛛舞。但是，尚不完全清楚这些特征是如何出现和多样化的。该项目将利用板球中快速发展的伴侣 - 牵引信号来了解这些特征的物理，生理和进化。这项研究将为大自然最有魅力的特征实时发展提供新颖和强迫的见解。该研究员将通过为K-12教室，心理本科生和来自代表性不足的团体的高中生开发进化游戏，并建立数字基础设施供科学家透露透明，同样招募丹佛大学的本科研究人员，从而扩大他们的社会影响。这将通过减少获得本科研究职位所需的社会资本来促进STEM的公平性。该研究员将整合计算和实验工具，以阐明夏威夷田野板球Teleogryllus Oceanicus的信号演化机制和机制。板球唱着激烈的纯色歌曲。在夏威夷人群中，致命的寄生虫（Ormia ochracea）窃听了唱歌的男性板球，造成了巨大的健身成本。这种自然选择的成本（寄生虫）和交配福利的推动推动驱动了允许秘密交流的新型信号的演变。的确，在过去的几年中，一种新颖的呼吸批判变体进化出来，吸引了女性的考虑，而不是寄生虫苍蝇。研究员1）执行人工选择实验来量化歌曲结构和女性偏好的遗传结构，2）构建有限的元素模型，以确定声学生物力学如何生成新颖的歌曲特征，3）执行生理评估以测试女性和寄生虫中的感觉能力，以及4）基于基于Angem的模型来测试Songs Extullution songs Extullution keless septions septions persection spersection spersection varry vary vary vary vary vary vary vary vary vary vary vary vary vary的效果如何。该研究员将接受进化生物学，心理学和生物物理学专家的培训，来自丹佛大学，圣奥拉夫学院和西安大略大学（加拿大）。该研究员还将开发K-12教育工具，精神高中和本科研究，并建立持久的基础设施，以促进丹佛大学的本科研究机会中的公平和透明度。该奖项反映了NSF的法定任务，并通过使用该基金会的知识分子优点和广泛的影响来评估Criceria的诚实支持。
