This project will increase understanding of the evolution of the parent-offspring conflict through an integrated set of research and education activities. This conflict is a striking paradox that is pervasive across the tree of life. Parents must balance the investment of limited resources between provisioning their offspring during early development to increase their chances for survival and maturation, and reserving resources for their own survival and future reproduction. The primary research aim of this project is to investigate the adaptations that regulate the parent-offspring conflict across diverse species. Moss plants are an ideal system to study this conflict since their offspring remain physically attached to and nutritionally dependent on the parental plant throughout their lifespan and the structures involved in the parent-offspring conflict vary across species. The research and education activities undertaken in this project will provide training and learning opportunities for a diverse group of students. The education components of this work will bring undergraduate students into the field and behind the scenes of natural history collections during an engaging May-term course at the University of Tennessee - Knoxville (UTK), where field collections and specimen-based research will be essential components of the class. Experiences and data from the course will then be used to build educational modules and activities for UTK’s grades 3-12 education programs, on campus natural history collections, and local public botanical gardens.This research will use an innovative and integrated approach that incorporates comparative analyses of functional morphology, physiology, and evolution using field-collected plants and natural history specimens to understand the processes that have led to diverse adaptations for regulating parental-offspring resource allocation across species. An interconnected set of hypotheses examining functional morphology and physiology will be tested comparatively using sets of diverse moss species to deepen understanding of the influence of the parent-offspring conflict on survival, fitness, and ultimately evolution of plants. This project will also generate a robust, globally sampled moss phylogeny in order to reconstruct patterns of morphological evolution and test for correlations between structures influencing the parent-offspring conflict. This research will lay the groundwork for future biodiversity studies in mosses, and will improve our knowledge and understanding of parent-offspring relationships broadly across plants.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.

该项目将通过一套综合的研究和教育活动，增加对父母-子女冲突演变的了解。这种冲突是一个惊人的悖论，在生命之树上无处不在。父母必须平衡有限资源的投资，在早期发育期间为其后代提供资源以增加其生存和成熟的机会，并为自己的生存和未来繁殖保留资源。本项目的主要研究目的是探讨不同物种之间调节亲子冲突的适应性。苔藓植物是研究这种冲突的理想系统，因为它们的后代在其整个生命周期中都保持对亲本植物的身体附着和营养依赖，并且参与亲子冲突的结构在物种之间存在差异。该项目开展的研究和教育活动将为各类学生提供培训和学习机会。这项工作的教育组成部分将使本科生进入该领域，并在田纳西大学诺克斯维尔（UTK），实地收集和以埃克塞特为基础的研究将是类的重要组成部分从事五月学期课程的自然历史收藏的幕后。从课程的经验和数据，然后将用于建立教育模块和活动的UTK的3-12年级的教育计划，在校园自然历史收藏，和当地的公共植物园。这项研究将使用一个创新的和综合的方法，结合功能形态学，生理学，和进化使用现场收集的植物和自然历史标本，以了解导致不同的适应调节跨物种的亲子资源分配的过程。一组相互关联的假设检查功能形态学和生理学将进行测试，比较使用不同的苔藓物种，加深理解的影响，父母后代的冲突对生存，健身，并最终进化的植物。该项目还将产生一个强大的，全球采样的苔藓植物发生，以重建形态进化的模式，并测试影响亲子冲突的结构之间的相关性。这项研究将为未来的苔藓生物多样性研究奠定基础，并将提高我们的知识和理解的父母-后代的关系广泛plants.This奖项反映了NSF的法定使命，并已被认为是值得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的支持。
