This action funds an NSF Postdoctoral Research Fellowship in Biology for FY 2015, Research Using Biological Collections. The fellowship supports a research and training plan for the Fellow to take transformative approaches to grand challenges in biology that employ biological collections in highly innovative ways. The title of the research plan for this fellowship to Laura Lagomarsino is "Disentangling the abiotic and biotic drivers of rapid plant evolution in the Andean biodiversity hotspot." The host institutions for this fellowship are the University of Missouri, St. Louis and the University of Gothenburg (Sweden), and the sponsoring scientists are Nathan Muchhala and Alexandre Antonelli. This fellowship is funded jointly with the Office of International Science and Engineering. Forming international collaborations is not only beneficial to the young scientist who conducts research at the foreign location, but is also in the U.S. national interest because that experience in a world-class research organization exposes the next generation of science leaders to the best the host country has to offer in terms of state-of-the-art research and the promises of continuing collaborations that will continue to strengthen U.S. science in the future.The Andean mountain chains of South America are home to exceptionally high levels of biodiversity, including one-sixth of all plant species. The 550 species of Neotropical bellflowers in the genera Centropogon, Burmeistera, and Siphocampylus represent just a small fraction of this diversity, but are one of the single largest Andean radiations. Hummingbirds and bats pollinate these species, which comprise a colorful and conspicuous element of the cloud forest flora. The herbarium collections at the Missouri Botanical Garden and the University of Gothenburg are being used to disentangle the relative roles that recent, dramatic mountain building and shifts between bat and bird pollinators have played in generating the outstanding diversity of Neotropical bellflowers. First it is necessary to infer a robust phylogeny, or pattern of evolutionary relationships. The specific method utilized (Hyb-Seq) is effective even when DNA quality and concentration are low, allowing herbarium specimens to be the primary source of genetic information. The extent to which geology has impacted diversification in the Neotropical bellflowers is then being investigated using models of Andean uplift, ecological niche modeling, and phylogenetic dating methods; these results are validated by fossil pollen core data. Finally, macro- and microevolutionary implications of pollinator shifts are being investigated using methods from comparative phylogenetics, pollination ecology, and population genetics. The microevolutionary component of the study couples extensive diurnal and nocturnal pollination observations with the quantification of gene flow in a putative case of sympatric speciation mediated by a shift from bat to hummingbird pollination.As the research is broadly interdisciplinary, training goals are to integrate techniques and viewpoints from phylogenetics, geology, pollination ecology, and population genetics. The Fellow is developing an educational module on vertebrate pollination suitable for K-12 students to be implemented as part of Missouri Botanical Garden's summer programming geared toward families. Additionally, the Fellow is developing and maintaining a website that makes high-resolution digital images of living and herbarium specimens of Neotropical bellflowers available to both the general public and researchers with specific interest in the group; this will be in addition to maintaining the Campanulaceae Working Group website. This Fellowship involves collaboration of researchers based in the US, Europe, and Latin America.

该行动为使用生物收集的研究基金为2015财年的生物学生物学奖学金提供了资金。奖学金支持该研究员的研究和培训计划，以采用变革性的方法来解决以高度创新的方式采用生物收集的生物学挑战。 该研究计划的劳拉·拉戈马尔斯诺（Laura Lagomarsino）的研究计划的标题“揭示了安第斯山脉生物多样性热点中快速植物进化的非生物和生物驱动因素”。该奖学金的主持机构是密苏里大学，圣路易斯大学和哥德堡大学（瑞典），赞助科学家是内森·莫·梅哈拉（Nathan Muchhala）和亚历山大·安东尼（Alexandre Antonelli）。 该奖学金由国际科学与工程办公室共同资助。 建立国际合作不仅对在外国进行研究的年轻科学家不仅有益，而且还处于美国国家的利益，因为世界一流的研究组织的这种经验使下一代科学领导者接触到了最佳的东道国。必须提供最先进的研究和继续合作的承诺，这些合作将在未来继续加强美国的科学。南美的安第斯山连锁店是极为高的生物多样性的家园，包括一种 - 所有植物物种中的第六。中心植物，缅甸和siphocampylus中的550种新热带气泡仅代表了这种多样性的一小部分，但是最大的安第斯辐射之一。蜂鸟和蝙蝠对这些物种进行了授粉，其中包括云森林菌群的五颜六色元素。密苏里州植物园和哥德堡大学的植物标本室收藏被用来解散最近的山区建筑以及蝙蝠和鸟传粉媒介之间的戏剧性山区建筑的相对角色，在产生了新热带风味的杰出多样性方面发挥了作用。首先，有必要推断出强大的系统发育或进化关系模式。 即使DNA质量和浓度较低，使用的特定方法（HYB-SEQ）也有效，从而使标本室标本成为遗传信息的主要来源。然后，使用Andean Uplift的模型，生态生态生态学建模和系统发育约会方法来研究地质影响新热带气水多样化的程度。这些结果通过化石花粉核心数据验证。最后，正在使用比较系统发育，授粉生态学和种群遗传学的方法研究了授粉媒介转移的宏观和微观进化意义。研究的微观进化组成部分伴侣在假定的同胞形成案例中，通过从BAT到蜂鸟授粉的转变介导的同性恋物种形成案例中，对基因流量进行定量进行了广泛的昼夜和夜间授粉观察，这是广泛的研究，培训目标是整合技术和整合技术和跨学科从系统发育，地质，授粉生态学和种群遗传学的观点。该研究员正在开发一个有关脊椎动物授粉的教育模块，适用于K-12学生，作为密苏里州植物园的夏季节目的一部分，适用于家庭。此外，该研究员正在开发和维护一个网站，该网站可以为普通公众和研究人员提供高分辨率数字图像，以对新热带风味的生活和植物标本室标本，对小组特别感兴趣；这将是维护Campanulaceae工作组网站的补充。该奖学金涉及在美国，欧洲和拉丁美洲的研究人员的合作。
