Long-term changes in climate are likely to alter future distributions of species. Predicting these changes depends upon understanding the factors that determine where species grow. This project will test whether the distributions of species of tropical trees along gradients of rainfall and on different soils in Puerto Rico can be predicted from the functional traits of the species, and whether the traits that a species has are constrained by its evolutionary past. Researchers will use herbarium specimens to quantify species distributions and examine the correspondence between the distributions and the traits of the species in one of the most biodiverse habitats in the U.S.The broader impacts associated with this investigation include teaching and training opportunities, networking and collaborations with conservation and management agencies, and contributions to public databases. Three paid internships to undergraduate students in Puerto Rico, New York City, and Washington, DC, will provide scientific training and research experience to students from underrepresented groups. Though an existing GK-12 award to Columbia University, the research will be linked to curricula in schools in New York City, which host a large number of students of Puerto Rican heritage. Findings will be disseminated to the Puerto Rico and US Virgin Islands Plant Conservation Task Force, a regional network of plant conservation practitioners which includes representatives from the USDA Forest Service, the U.S. Fish and Wildlife Service, the Department of Natural Resources of Puerto Rico, and the University of Puerto Rico. Information on the specimens used in the research will be provided directly to participating herbaria and the data on molecular sequences and functional traits assembled for the project work will be deposited in online databases.

气候的长期变化可能会改变物种的未来分布。 预测这些变化取决于理解确定物种在哪里生长的因素。 该项目将测试沿降雨梯度和波多黎各的不同土壤的热带树种的分布，可以从该物种的功能性状中预测，以及该物种的特征是否受到其进化的过去的限制。研究人员将使用标本室标本来量化物种分布，并检查该物种在美国最生物多样性栖息地之一的分布和特征之间的对应关系，与该调查相关的更广泛的影响包括教学和培训机会，包括与保护和管理机构的网络和协作，以及对公共数据库的贡献。 向波多黎各，纽约市和华盛顿特区的本科生进行了三项付费实习，将为来自代表性不足的团体的学生提供科学培训和研究经验。 尽管这项研究是哥伦比亚大学现有的GK-12奖，但该研究将与纽约市学校的课程有关，该课程拥有大量波多黎各人遗产的学生。 调查结果将被传播到波多黎各和美国维尔京群岛植物保护工作组，这是一个植物保护从业人员的区域网络，其中包括美国农业部森林服务局，美国鱼类和野生动物服务局，波多黎各自然资源部，波多黎各和波多黎各大学的代表。 有关研究中使用的标本的信息将直接提供给参与的草本植物，以及针对项目工作组装的分子序列和功能性状的数据，将存放在在线数据库中。
