项目摘要

Over the past 2 decades, marine ecology has seen a shift in focus from documenting biodiversity to wanting to understand the importance of biodiversity to the services that marine ecosystems contribute to human society and to our planetary support system. Ecologists assign functional traits or 'ecosystem job descriptions' to species and groups of species that define their role in ecosystems, from photosynthesis, nutrient cycling and predation to the production of fish stocks. On the other hand ecologists who study marine microorganisms have been comparatively slower to make this change in perspective. In part, this is because new, high throughput gene sequencing methods are providing marine microbiologists with information at a level that surpasses the development of meaningful ecological interpretation. This research program will focus on marine reducing habitats, where changes in dissolved oxygen cause shifts in microbial composition and metabolism. These gradients of environment change provide opportunities to directly observe relationships between microbial diversity, and the metabolic processes that microbes contribute to ecosystem function. Over the past several years my laboratory has developed or implemented a number of analytical tools that will be brought to bear on this question.

在过去的20年里，海洋生态学的重点已经从记录生物多样性转变为希望了解生物多样性对海洋生态系统为人类社会和我们的地球支持系统做出贡献的服务的重要性。生态学家为物种和物种群分配功能特征或“生态系统工作描述”，这些特征定义了它们在生态系统中的作用，从光合作用、营养循环、捕食到鱼群的生产。另一方面，研究海洋微生物的生态学家在改变观点方面相对较慢。在某种程度上，这是因为新的高通量基因测序方法为海洋微生物学家提供的信息水平超过了有意义的生态解释的发展。这个研究项目将集中在海洋减少栖息地，在那里溶解氧的变化导致微生物组成和新陈代谢的变化。这些环境变化的梯度为直接观察微生物多样性之间的关系以及微生物对生态系统功能的代谢过程提供了机会。在过去的几年里，我的实验室已经开发或实施了一些分析工具，这些工具将会对这个问题产生影响。
