Abstract Proposal: OISE-1132916 PI/Institution: Weiblen, George D., University of Minnesota-Twin CitiesDr. George Weiblen from the University of Minnesota and Dr. Santiago Madriñan from the Universidad de Los Andes in Colombia propose a new international collaboration to lay down the systematic foundations for studying the ecology and evolution of an important tropical tree,Cecropia,and its ant inhabitants. Specifically the PIs plan to apply a network analytical approach to quantify ant associations with plants across six Colombian bio-geographical regions where the diversity of Cecropia species is high. For each study site the PIs will develop an ant-plant association matrix to quantify the relative importance of ecological and evolutionary processes in assembling ecological communities. The PIs are committed to including junior scientists in the proposed collaboration. In particular this project will give a US PhD student the opportunity to receive interdisciplinary training in systematics and ecology and be mentored by Colombian colleagues with expertise in phylogenetics, plant DNA analysis and ant ecology. Furthermore, the proposed collaboration where the PIs locate the molecular work in the same country where samples originate while sharing digital data, represents a new model for rapid systematic progress. This model addresses a requirement under the International Convention on Biodiversity which restricts material transfer in developing countries. Additionally, the PIs and the students will exchange information between Colombia and the US through the submission of DNA sequences to GenBank, scientific publications, and presentations at professional meetings.

摘要提案：OISE-1132916 PI/机构：Weiblen，乔治D.，明尼苏达大学双城分校来自明尼苏达大学的乔治·魏布伦和哥伦比亚安第斯山脉大学的圣地亚哥·马德里尼安博士提议开展一项新的国际合作，为研究一种重要的热带树木--Cecropia及其蚂蚁居民的生态学和进化奠定系统基础。 具体来说，PI计划应用网络分析方法来量化蚂蚁协会与植物在哥伦比亚六个生物地理区域，其中Cecropia物种的多样性很高。 在每一个研究地点，PI将开发一个蚂蚁-植物关联矩阵，以量化生态和进化过程在组装生态群落中的相对重要性。PI致力于将年轻科学家纳入拟议的合作。 特别是，该项目将为美国博士生提供机会，接受系统学和生态学的跨学科培训，并由哥伦比亚同事指导，在植物遗传学，植物DNA分析和蚂蚁生态学方面具有专业知识。 此外，拟议的合作，即PI将分子工作定位在样本来源的同一个国家，同时共享数字数据，代表了快速系统化进展的新模式。 这一模式涉及《国际生物多样性公约》中限制在发展中国家进行材料转让的一项要求。 此外，PI和学生将通过向GenBank提交DNA序列，科学出版物和专业会议上的演讲在哥伦比亚和美国之间交换信息。
