项目摘要

This award supports a symposium and workshop, the goal of which is to highlight how biological exchanges between salty and freshwater habitats have transformed the biosphere. Life in the ocean and in freshwater habitats have long been intertwined. Major branches of the tree of life originated in the oceans and colonized fresh waters, often adapting to the new regime and diversifying. Similar exchanges continue to this day, including some species that continually migrate between salty and fresh waters. Scientists who study these processes typically focus on a single group of living organisms, or on the fossil record that documents ancient colonizations. The purpose of the activities supported by this grant is to stimulate new research on the history of life and present-day stresses to aquatic systems. Planned activities will consist of a day-long symposium during the 2022 Annual Meeting of the Society for Integrative and Comparative Biology, and a one-day workshop designed to facilitate innovative thinking and the involvement of scientists who are diverse in disciplinary orientation, country of origin, and stage of professional development. These interactions will yield products including manuscripts that synthesize research findings across disciplines and grant proposals for new research on gaps in knowledge that have been highlighted by the workshop collaborations. Because global conditions such as sea level that shaped ancient exchanges are currently changing at a rapid rate due to intensifying human impacts, the results of the symposium and workshop should help scientists understand emerging threats to biodiversity related to changes in aquatic habitat solute concentration and global climate change.The symposium and workshop will address several questions about how biotic exchange between salty and fresh habitats has transformed the biosphere: When did major colonizations of fresh waters happen? What circumstances facilitated the transition? How frequent have been returns to marine habitats? How porous is the boundary: is change in halohabitat routine, requiring few modifications, or does it rarely occur because it requires special conditions and substantial genomic alterations? What adaptive changes occurred to accommodate the physiochemical and ecological differences? How do marine and freshwater lineages differ in organism-level features, ecological relationships, evolutionary processes? To what extent has diversification been propelled by the transitions? What differences in ecosystem services arise from these transformations? In what ways are the freshwater and marine forms subject to different anthropogenic stressors? The symposium, workshop, and resulting products will integrate findings at multiple levels of biological organization and from disparate fields, and use this science to better understand responses to global change in each realm. The transdisciplinary approach will allow participants to establish new collaborations and address questions that cross disciplinary boundaries, thereby stimulating new research to fill identified gaps in knowledge. Diverse scientists from a broad range of disciplines, including graduate students and individuals from groups under-represented in science, will participate, and results will be disseminated in journal articles, white papers, and via a project website, Twitter account and Instagram feed. The resulting collaborations will enhance interactions across biological and geoscience disciplines and will impact interdisciplinary curricula for undergraduate and graduate students.This award is co-funded by the Physiological Mechanisms and Biomechanics Program in the Division of Integrative Organismal Systems, Directorate for Biological Sciences, and the Sedimentary Geology and Paleobiology Program in the Division of Earth Sciences, Directorate for Geosciences.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.

该奖项支持举办研讨会和研讨会，其目的是强调咸水和淡水栖息地之间的生物交换如何改变了生物圈。海洋和淡水栖息地的生命长期以来一直交织在一起。生命之树的主要分支起源于海洋并在淡水中定居，通常会适应新的环境并实现多样化。类似的交流至今仍在继续，包括一些不断在咸水和淡水之间迁徙的物种。研究这些过程的科学家通常关注一组生物体，或记录古代殖民的化石记录。这笔赠款支持的活动的目的是促进对生命历史和当今水生系统压力的新研究。计划的活动将包括在 2022 年综合与比较生物学学会年会上举行为期一天的研讨会，以及为期一天的研讨会，旨在促进创新思维和不同学科方向、原籍国的科学家的参与和职业发展阶段。这些互动将产生产品，包括综合跨学科研究成果的手稿，并为研讨会合作强调的知识差距的新研究提供建议。由于人类影响加剧，影响古代交流的海平面等全球条件目前正在迅速变化，因此研讨会和研讨会的结果应有助于科学家了解与水生栖息地溶质浓度和全球气候变化相关的生物多样性面临的新威胁研讨会和研讨会将讨论有关咸水和淡水栖息地之间的生物交换如何改变生物圈的几个问题：淡水的主要殖民化何时发生？哪些情况促进了这一转变？返回海洋栖息地的频率如何？边界有多少漏洞：是盐生地常规的变化，需要很少的修改，还是很少发生，因为它需要特殊的条件和大量的基因组改变？为了适应生理化学和生态差异，发生了哪些适应性变化？海洋和淡水谱系在生物水平特征、生态关系、进化过程方面有何不同？转型在多大程度上推动了多元化？这些转变导致生态系统服务出现哪些差异？淡水和海洋形态以何种方式受到不同的人为压力源影响？研讨会、研讨会和由此产生的产品将整合生物组织多个层面和不同领域的发现，并利用这门科学更好地了解每个领域对全球变化的反应。跨学科方法将使参与者能够建立新的合作并解决跨学科界限的问题，从而激发新的研究来填补已发现的知识空白。来自广泛学科的不同科学家，包括研究生和来自科学领域代表性不足的群体的个人，将参与其中，研究结果将通过期刊文章、白皮书以及项目网站、Twitter 帐户和 Instagram 传播。由此产生的合作将加强生物和地球科学学科之间的互动，并将影响本科生和研究生的跨学科课程。该奖项由生物科学理事会综合有机体系统司的生理机制和生物力学项目以及地球科学局地球科学部的沉积地质学和古生物学计划。该奖项反映了 NSF 的法定使命，并通过评估认为值得支持基金会的智力价值和更广泛的影响审查标准。
