项目摘要
Non-Technical Abstract:If we continue to burn fossil fuels at the current rate, by 2100 we may reach a climate state not seen since the early Eocene Epoch, ~50 million years ago, when the poles were ice-free. Because fundamental holes remain in our understanding of how such hothouse worlds work, it is essential to collect new paleontological data from globally warm time intervals. The PI will assemble teams of students, postdocs, and collaborating geoscientists to excavate leaf fossils from early Eocene sites across Wyoming and northern Colorado. Leaf fossils tell us what plants were alive in a particular time and location, and they can also be used to estimate past temperature and precipitation levels. Well-preserved leaf fossils even show traces of ancient insect feeding damage, allowing us to reconstruct plant-insect food webs, which today account for up to 75% of terrestrial biodiversity. Comparing fossils from different sites allows the group to test hypotheses about biodiversity, migrations, and biotic resilience during hothouse conditions. Understanding past greenhouse worlds and applying this knowledge to today's warming world is a significant challenge that will require a diverse workforce, but, at present, the paleontological and geological communities are lacking in diversity. The research activities that the PI outlines here aim to increase training opportunities for aspiring female scientists, and the outreach objectives complement this by showcasing, as role models, inspirational female field scientists, drawing attention to their trials and triumphs and making them more accessible to the general public. The cornerstone of these efforts, The Bearded Lady Project: Challenging the Face of Science, is an innovative collaboration with professional artists to produce a live-action documentary and develop and display a touring portrait series that identifies women working in the geosciences and brings to light the obstacles that they face. Through this project, the investigator will aim to combat implicit and unintentional gender biases while inspiring new generations of women to enter the field.Technical Abstract:Analysis of the fossil record permits us to investigate how ecosystems function during very different climate regimes and to evaluate the effects of climate on ecosystems and evolution. The warm, equable, and ice-free Early Paleogene (66-50 Ma) is ideal for study because it simultaneously provides a marked contrast to the present, as well as insight into what the future may entail. The PI will assemble teams of students, postdocs, and collaborating geoscientists to collect new paleobotanical, paleoecological, and paleoclimatic data from understudied Early Paleogene sedimentary basins of Wyoming and northern Colorado. The group will synthesize the data they collect with the high-resolution record from the Bighorn Basin of northwestern Wyoming in order to: (i) assess the diversity, structure, and ecology of forest ecosystems during the Early Paleogene hothouse; (ii) test hypotheses about endemism, latitudinal gradients, migrations, and biotic resilience during hothouse conditions, and (iii) construct regional to continental-scale biogeographic and paleoclimatic maps. In order to calibrate the fossil data and to determine which modern macro-ecological patterns are also characteristic of greenhouse worlds, the group will collect ecological data from four extant forests, using the same methodologies as for fossil assemblages. The educational objectives of this proposal complement the strongly field-based research agenda by showcasing, as role models, some inspirational female field scientists and providing opportunities for aspiring scientists, particularly women, to conduct field-based research. The outreach efforts attempt to bring female geoscientists into the public eye through an innovative project entitled The Bearded Lady Project: Challenging the Face of Science. In it, the investigator will collaborate with a professional photographer and film director to produce both a live-action documentary and a touring portrait series focused on the challenges and obstacles faced by inspirational women in the geosciences.
非技术摘要:如果我们继续以目前的速度燃烧化石燃料,到2100年,我们可能会达到自5000万年前始新世早期以来从未见过的气候状态,当时两极没有冰。由于我们对这些温室世界如何运作的理解仍然存在根本性的漏洞,因此从全球变暖的时间间隔中收集新的古生物学数据至关重要。PI将召集学生、博士后和合作的地球科学家组成团队,从怀俄明州和北方科罗拉多的始新世早期遗址挖掘叶子化石。叶子化石告诉我们在特定的时间和地点有哪些植物活着,它们也可以用来估计过去的温度和降水量。保存完好的叶子化石甚至显示出古代昆虫进食破坏的痕迹,使我们能够重建植物-昆虫食物网,今天占陆地生物多样性的75%。比较来自不同地点的化石使该小组能够测试有关生物多样性,迁移和生物在温室条件下的恢复力的假设。了解过去的温室世界并将这些知识应用于当今变暖的世界是一项重大挑战,需要多样化的劳动力,但目前,古生物和地质社区缺乏多样性。 PI在此概述的研究活动旨在增加有抱负的女科学家的培训机会,外联目标通过展示鼓舞人心的女实地科学家作为榜样,提请注意她们的考验和胜利,并使她们更容易为公众所接受,来补充这一点。 这些努力的基石,大胡子女士项目:塑造科学的面貌,是与专业艺术家的创新合作,以制作一部真人纪录片,并开发和展示一个巡回肖像系列,以确定在地球科学领域工作的妇女,并揭示她们面临的障碍。 通过这个项目,研究者将致力于打击隐性和无意的性别偏见,同时激励新一代的女性进入该领域。技术摘要:化石记录的分析使我们能够调查生态系统如何在非常不同的气候制度和评估气候对生态系统和进化的影响。温暖、平静、无冰的早第三纪(66-50 Ma)是研究的理想时期,因为它同时提供了与现在的明显对比,以及对未来可能需要的洞察力。PI将召集学生、博士后和合作的地球科学家团队,从怀俄明州和北方科罗拉多未充分研究的早第三纪沉积盆地收集新的古植物学、古生态学和古气候数据。该小组将把他们收集的数据与来自怀俄明州西北部比格霍恩盆地的高分辨率记录进行综合,以便:(i)评估古近纪早期森林生态系统的多样性、结构和生态温室; ㈡检验关于地方性、纬度梯度、迁移和温室条件下生物复原力的假设,和(iii)构建区域到大陆尺度的地理和古气候图。为了校准化石数据并确定哪些现代宏观生态模式也是温室世界的特征,该小组将使用与化石组合相同的方法从四个现存森林收集生态数据。这项建议的教育目标是通过展示一些鼓舞人心的女性实地科学家作为榜样,并为有抱负的科学家,特别是妇女,提供进行实地研究的机会,补充强有力的实地研究议程。 外联工作试图通过一个名为“大胡子女士项目:美化科学面貌”的创新项目,使女性地球科学家进入公众视野。在其中,调查员将与专业摄影师和电影导演合作,制作真人纪录片和巡回肖像系列,重点关注地球科学领域鼓舞人心的女性所面临的挑战和障碍。
