Northern aquatic microbiomes faced with rapid environmental change.

微生物是水生生态系统的重要组成部分，种类繁多。我的研究项目使用新的基于基因组学的分子方法来调查这些重要的水生微生物的生物多样性、代谢多样性和进化。正在调查的水生生态系统包括北部海洋、河口，以及最近季节性冰覆盖的北部湖泊。所有这些生态系统都不同程度地受到气候变化和其他人为干扰的影响。我的研究计划旨在为微生物的分布和活动可能如何受到这些环境压力的影响提供见解，长期目标是发展对水生态系统中微生物如何响应环境变异性的预测性理解。以前，我们使用先进的基因组学方法来发现和描述海岸和河口海洋系统中重要的碳、氮和硫循环代谢途径。

Microorganisms are a diverse and important component of aquatic ecosystems. My research program investigates the biodiversity, metabolic versatility, and evolution of these important aquatic microbes using novel genomics-based molecular approaches. Aquatic ecosystems under investigation include northern oceans, estuaries, and most recently, seasonally ice-covered northern lakes. All these ecosystems are impacted by climate change and other anthropogenic perturbations to varying degrees. My research program is coordinated to provide insights into how microbial distributions and activities may be influenced by these environmental pressures and the long-term objective is to develop a predictive understanding of how microorganisms respond to environmental variability in aquatic ecosystems. Previously, we employed advanced genomics approaches to discover and describe important carbon, nitrogen, and sulfur cycling metabolic pathways in coastal and estuarine marine systems.
