项目摘要

This research will unravel the evolutionary history of a complex parasite-host system, specifically, ant species that are parasites of the colonies of other ant species. This parasite-host system has evolved many times across ant species, but it is unknown how this convergently evolved behavior has affected speciation patterns in the social parasites. The project uses an integrative approach that includes (i) reconstructing the speciation patterns and the evolutionary history of ant social parasites using genetic data from ant genomes; (ii) unearthing the global biodiversity of ant social parasites using new methods to biodiversity discovery to effectively delimit species and revise the classification of ant social parasites across the ant tree of life; (iii) deciphering the genetic mechanisms underlying the formation of new social parasite species. In summary, this project integrates several approaches to understand organismal evolutionary biology, exploring how parasitic lineages originate repeatedly.Understanding the origin and maintenance of biological diversity is a major goal in evolutionary biology. Speciation by evolving reproductive isolation in allopatry is well accepted. However, theoretical and empirical studies have established that reproductive isolation can evolve in sympatry, in the absence of geographical isolation. Empirical evidence for sympatric speciation has been accumulating from studies of ant inquiline social parasites. Inquiline parasites inhabit the living space of other species. The social parasites of ants are other ant species, often closely related, that are highly specialized brood parasites. The parasitic species exploit their hosts’ social organization to selfishly maximize their individual reproductive output. In contrast to other species that evolved via sympatric speciation, the diverse assemblage of ant social parasites is a promising and underutilized system for comparative study because at the moment approximately 390 ant social parasite species are known from 34 genera. The high number of independently evolved parasite species provides unique conditions for comparative research exploring the ecological circumstances and the genetic mechanisms associated with the independent evolutionary origins of ant social parasites. This project integrates research, education, and outreach, and will therefore benefit society in general. Graduate and undergraduate students will be trained in organismal evolutionary biology in both the laboratory and the field, and novel undergraduate field biology classes will be developed at Arizona State University (ASU). Collaborations with colleagues in South America and Europe will facilitate the international exchange of students and long-term enhancement of a global scientific community. The outreach program will (i) train teachers at elementary, middle, and high schools with high percentages of under-represented and disadvantaged groups in the Phoenix Metro area, (ii) integrate community colleague students into teaching and research activities at ASU, (iii) use social parasites as a tool to start a conversation about controversial or socially loaded metaphors in science, and (iv) offer student workshops to integrate social and brood parasitism research across the animal kingdom.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.

这项研究将揭示复杂的寄生虫-宿主系统的进化历史，特别是作为其他蚂蚁物种群体的寄生虫的蚂蚁物种，这种寄生虫-宿主系统在蚂蚁物种中已经进化了多次，但尚不清楚这是如何趋同的。进化的行为影响了社会寄生虫的物种形成模式，包括（i）利用蚂蚁基因组的遗传数据重建蚂蚁社会寄生虫的物种形成模式和进化历史；蚂蚁社会寄生虫的全球生物多样性，使用生物多样性发现的新方法来有效地界定物种并修改蚂蚁生命树中蚂蚁社会寄生虫的分类；（iii）破译新社会寄生虫物种形成的遗传机制。，该项目整合了多种方法来理解有机体进化生物学，探索寄生谱系如何重复起源。理解生物多样性的起源和维持是进化生物学的一个主要目标，通过异域进化生殖隔离来形成物种已被广泛接受。然而，理论和实证研究已经证实，在没有地理隔离的情况下，生殖隔离可以在同域物种形成中进化，对蚂蚁社会寄生虫栖息在其他物种的生活空间中的研究不断积累。蚂蚁的寄生虫是其他蚂蚁物种，通常密切相关，是高度专业化的寄生虫，与其他物种相比，寄生物种利用宿主的社会组织来自私地最大化其个体繁殖产出。通过同域物种形成进化而来的蚂蚁社会寄生虫的多样化组合是一个很有前途但未得到充分利用的比较研究系统，因为目前已知来自 34 个属的大约 390 种蚂蚁社会寄生虫物种，大量独立进化的寄生虫物种为它们提供了独特的条件。探索与蚂蚁社会寄生虫的独立进化起源相关的生态环境和遗传机制的比较研究，这整合了项目研究、教育和推广，因此将有益于整个社会的研究生和本科生的培训。亚利桑那州立大学（ASU）将在实验室和现场开发生物进化生物学，以及新颖的本科生现场生物学课程，与南美和欧洲的同事合作将促进学生的国际交流和长期增强。该外展计划将 (i) 培训菲尼克斯都市区代表性不足和弱势群体比例较高的小学、初中和高中的教师，(ii) 让社区同事学生参与到教学和研究活动中。亚利桑那州立大学，(iii) 使用社会寄生虫作为开始讨论科学中有争议或社会负荷隐喻的工具，以及（iv）提供学生研讨会，以整合整个动物王国的社会和巢寄生研究。该奖项反映了 NSF 的法定使命，并通过评估被认为值得支持利用基金会的智力优势和更广泛的影响审查标准。
