项目摘要

Temperate and tropical forests contain a significant proportion of our planet's biodiversity, and they provide important ecosystem services that include climate regulation. Despite their importance, the processes that produce and maintain biodiversity within and among forested ecosystems remain poorly understood. This lack of understanding applies to diverse tropical and subtropical forests, and also to less diverse temperate forests. Further, the insights we do have about forest diversity primarily concern species diversity; far less is known about the processes regulating the phylogenetic, functional and genetic dimensions of biodiversity that are likely to be more closely related to ecosystem function.Patterns of phylogenetic, genetic, and functional diversity, and their roles in maintaining biological diversity, will be examined in temperate and subtropical forests in the United States and in China. A combination of experimental and observational research will lead to a new approach - termed community functional phylogenomics - that should provide detailed insights into the causes and consequences of the levels of biodiversity in forests. The research will inform forest management, it will strengthen collaboration between researchers in the United States and China, and the project will fund a joint training workshop for graduate students and early career scientists in both countries.

温带和热带森林包含我们地球生物多样性的很大一部分，它们提供了包括气候调节在内的重要生态系统服务。尽管它们的重要性，但在森林生态系统内部及其之间产生和维持生物多样性的过程仍然知之甚少。缺乏理解适用于多样化的热带和亚热带森林，也适用于较少的温带森林。此外，我们对森林多样性的见解主要涉及物种多样性。关于调节生物多样性的系统发育，功能和遗传维度可能与生态系统功能更紧密相关的过程的过程，还将在美国和中国和中国的美国和亚热带森林中进行研究。实验研究和观察性研究的结合将导致一种新方法 - 称为社区功能系统基因组学 - 应为森林中生物多样性水平的原因和后果提供详细的见解。这项研究将为森林管理提供信息，它将加强美国和中国研究人员之间的合作，该项目将为研究生和两国的早期职业科学家提供联合培训研讨会。
