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?

现在我们知道，只要环境发生变化，进化就会迅速进行。这种演变应该对生态格局和进程产生重要影响，包括种群动态（丰度）、群落结构（生物多样性）和生态系统功能（服务）。亨德利在Galápagos上研究了这些影响，特别关注植物如何塑造雀喙的进化，以及这种进化如何反馈影响植物群落。需要解决四个关键问题。雀类特征分布如何影响种子和植物群落？植物是如何进化以应对雀类的？这些从进化到生态效应的遗传基础是什么？人类是如何影响这些生态进化动态的？
