It is largely unknown how marine animals today will respond to current and future environmental change. This research is using the geologic record of a mass extinction event 66 million years ago as a natural laboratory to understand habitat loss and species survival during rapid environmental changes. The systematically collected paleo-environment and fossil data are the foundation of immersive, online 'Virtual Field Experiences' that engage students with the field collection and lab processing methods of Earth Sciences research. Online experiences and lesson plans aligned with Next Generation Science Standards are broadly available through well-known online portals and disseminated to teachers in the Gulf Coast states.Periods of extreme, rapid environmental change in Earth history are informative for predicting current and future survivorship in response to changing climate. These events also provide the opportunity to test hypotheses on macroevolutionary pattern and process. This project involves compiling species occurrences and paleoenvironments across the end-Cretaceous mass extinction (~66 Ma) in the U.S. Gulf Coastal Plain. Topics of investigation include (1) the impact of available suitable habitat and habitat continuity on extinction potential; (2) the impact of extreme environmental change on patterns of niche stability within species, and phylogenetic niche conservation within clades; and (3) the influence of extreme environmental change on macroecological shifts in body size and physiological flexibility. This research supports three female early-career PIs, and graduate and undergraduate students at five institutions (two of which serve non-traditional, minority-majority student populations) are trained in field, laboratory, and analytical Earth Science. Two Virtual Field Experiences with high school-level lesson plans will emphasize hypothesis testing and the significance of extinction events.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.

当今的海洋动物将如何应对当前和未来的环境变化，这在很大程度上尚不清楚。这项研究正在使用6600万年前的大规模灭绝事件的地质记录作为自然实验室，以了解在快速环境变化期间栖息地丧失和物种存活。系统地收集的古环境和化石数据是沉浸式的在线“虚拟现场体验”的基础，可让学生与地球科学研究的现场收集和实验室处理方法相关。与下一代科学标准保持一致的在线体验和课程计划可通过众所周知的在线门户网站获得，并传播给墨西哥湾沿岸州的教师。地球历史上极端，快速的环境变化的期限对于预测当前和未来的生存方面的响应是为了响应变化的气候。这些事件还提供了测试宏观进化模式和过程的假设的机会。该项目涉及在美国墨西哥湾沿海平原上汇编物种发生和古环境。调查主题包括（1）可用的适当栖息地和栖息地连续性对灭绝潜力的影响； （2）极端环境变化对物种内部利基稳定模式的影响，以及进化枝内的系统发育利基保护； （3）极端环境变化对体型和生理柔韧性宏观生态转移的影响。这项研究支持三个女性早期PIS，以及五个机构的研究生和本科生（其中两个服务于非传统，少数少数少数学生的学生人群）接受了现场，实验室和分析地球科学的培训。高中课程计划的两种虚拟现场经验将强调假设检验和灭绝事件的重要性。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估审查标准来通过评估来支持的。
