This action funds an NSF Postdoctoral Research Fellowship in Biology for FY 2020, Research Using Biological Collections. The fellowship supports research and training of the fellow that will use biological collections in innovative ways. Plants and the insect herbivores that consume them comprise over half of all described species and their interactions are a cornerstone of food webs. The fossil record of plants has the marks of insect herbivory, such as holes chewed into a leaf, and these provide an excellent source of evidence for understanding ancient forests and how they changed through time. The research fellow will measure the recovery of plants and insects before, during, and after the Cretaceous/Paleogene (K/Pg) extinction event, which occurred 66.04 million years ago. There are many studies on the extinction of the dinosaurs and the subsequent rise of mammals, but the recovery of plants and insects is poorly understood and is the focus of this study. This research project will enhance the fellow’s curatorial skills, data analytical skills, publication record, and experience in public outreach and mentoring. The outreach will connect citizens with exciting stories about fossils from the Corral Bluffs site, highlight the importance of museum collections in cutting-edge scientific research, emphasize the significance of museums in our communities, and engage the general public with scientific concepts to increase awareness of the connections with nature. The research will constitute the most highly-resolved stratigraphic analysis of plant‒insect associations across the K/Pg boundary to-date, documenting the extinction and recovery of plant and insect life into the first million years following the extinction. This research will utilize the Corral Bluffs Paleobotanical Collection at the Denver Museum of Nature & Science (DMNS), under the guidance of Dr. Ian Miller (Curator of Paleobotany, DMNS) and Dr. Ellen Currano (University of Wyoming). By analyzing the diversity and intensity of plant‒insect associations at the Corral Bluffs study site, the fellow will generate one of the largest data sets of plant–insect interactions for the terminal Cretaceous and early Paleocene, and the highest quality plant‒insect associational dataset collected from across the K/Pg boundary. The statistical analyses for this research will include building bipartite networks linking plant species. The fellow will be trained on paleobotanical identification, taxonomic descriptions, and will learn new statistical analyses. Broadly anticipated results include more diverse and specialized insect damage during the Cretaceous, very little insect damage immediately after the extinction, and a step-wise increase of plant and insect diversity in the following one million years. Broader impacts will include public outreach through the Denver Museum of Nature & Science.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.

该行动为使用生物收集的研究基金为2020财年生物学的NSF博士后研究奖学金提供了资金。奖学金支持将以创新的方式使用生物收集的研究员的研究和培训。植物和隔热的食草动物消耗了所有描述的物种及其相互作用的一半以上是食物网的基石。植物的化石记录具有绝缘的痕迹，例如咀嚼叶子的孔，它们为了解古代森林以及它们如何随着时间而变化提供了极好的证据来源。研究人员将在白垩纪/古近纪（K/PG）扩展事件之前，之中和之后衡量植物和绝缘材料的恢复，该事件发生在6604万年前。关于恐龙的扩展和随后的哺乳动物的兴起，有许多研究，但是植物和绝缘材料的恢复鲜为人知，这是重点。这项研究。该研究项目将提高同胞的策展技能，数据分析技能，出版记录以及公共外展和心理方面的经验。宣传将使公民与有关化石的激动人心的故事联系起来，强调博物馆收藏在尖端科学研究中的重要性，强调博物馆在我们社区中的重要性，并以科学的概念吸引公众，以提高人们对与大自然联系的认识。这项研究将构成对K/PG边界待定植物的关联的最高度分辨的地层分析，以记录扩展后最初的百万年度植物和绝缘寿命的扩展和恢复。这项研究将在丹佛自然与科学博物馆（DMNS）的Corral Bluffs古植物学系列中，在伊恩·米勒（Ian Miller）博士（古植物学，DMNS的策展人）和艾伦·柯拉诺（Ellen Currano）（怀俄明大学）的指导下。通过分析Corral Bluffs研究地点的植物 - 启用关联的多样性和强度，该研究员将生成最大的植物 - 植物 - 剂量相互作用之一，用于终末白垩纪和早期古新世，以及从K/PG边界收集的最高质量的植物与植物 - 启动的关联数据集。这项研究的统计分析将包括建立将植物物种联系起来的双方网络。该研究员将接受古植物学识别，分类学描述的培训，并将学习新的统计分析。广泛预期的结果包括在白垩纪期间更多的潜水员和专门的绝缘材料，延伸后立即进行绝缘损坏，以及在接下来的一百万年内逐步增加植物和绝缘多样性。更广泛的影响将包括通过丹佛自然与科学博物馆的公共宣传。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响评估标准，被视为通过评估来获得珍贵的支持。
