Recent research by the PI has addressed the evolutionary diversification of plants that have evolved and diversified first in South America, but have radiated into the northern hemisphere and to other continents. In particular, his recent work has helped understand the connection between arid land floras in South and North America in Verbenaceae, a family well represented in those regions. The research proposed here extends that work to the tropics by examining the diversification of the Lantana complex using molecular phylogenetic and niche-modeling methods. This study will permit testing of hypotheses concerning the importance of seed dispersal by animals to achieving geographic distributions observed today. Understanding the evolution of biodiversity in space and time represents a global challenge that is met best by international collaboration. The PI will collaborate with scientists in several Latin American countries throughout the course of this research. These collaborations strengthen the ties between US research institutions and their counterparts, on which international cooperation and goodwill depend. The results obtained by the proposed research will serve as baseline data for understanding how species distributions change when climates change. With his position as a curator in the Burke Museum, the PI will develop exhibits to interpret this research, both in the museum and on-line, to the visiting public and school groups.

PI最近的研究已经解决了植物的进化多样性，这些植物首先在南美洲进化和多样化，但已经辐射到北方和其他大陆。特别是，他最近的工作有助于了解马鞭草科（Verbenaceae）中南美和北美干旱土地植物区系之间的联系，马鞭草科在这些地区有很好的代表性。这里提出的研究扩展到热带地区的工作，通过研究的多样化的马缨丹复杂的分子系统发育和生态位建模方法。这项研究将允许测试假设的重要性，种子传播的动物实现地理分布观察到今天。 了解生物多样性在空间和时间上的演变是一项全球性挑战，最好通过国际合作来应对。PI将在整个研究过程中与几个拉丁美洲国家的科学家合作。这些合作加强了美国研究机构与其同行之间的联系，国际合作和善意依赖于此。拟议研究获得的结果将作为了解气候变化时物种分布如何变化的基线数据。作为伯克博物馆的馆长，PI将在博物馆和在线上开发展览来解释这项研究，向来访的公众和学校团体。
