Evolution is now known to proceed rapidly whenever environments change. This evolution should have important consequences for ecological patterns and processes, including population dynamics (abundances), community structure (biodiversity), and ecosystem function (services). Hendry studies these effects in Galápagos, focusing especially on how plants shape the evolution of finch beaks and how that evolution feeds back to influence plant communities. Four key questions are to be addressed. How do finch trait distributions influence seed and plant communities? How are plants evolving in response to finches? What is the genetic basis for these evo-to-eco effects? How are humans influencing these eco-evolutionary dynamics?

现在已知Evolution在环境发生变化时会迅速进行。这种进化应该对生态模式和过程产生重要影响，包括人群动态（丰度），社区结构（生物多样性）和生态系统功能（服务）。 Hendry研究了加拉帕戈斯群岛的这些影响，特别是植物如何塑造细喙的演变以及该进化如何反馈影响植物群落。要解决四个关键问题。精细的性状分布如何影响种子和植物群落？植物如何响应罚款？这些EVO到ECO效应的遗传基础是什么？人类如何影响这些生态进化动态？
