Outline of Final Research Achievements |
Natural ecosystems can be conceptually thought of as interconnected environmental and metabolic systems. Humans and their activities affect and are a part of these ecosystems. Considering a more applied perspective of human activities within ecosystems, it is important to gain an understanding of natural ecology and its metabolic processes in various environments. We have shown the challenges of analytical approaches for molecular and microbial complexity in the ecosystem. The first challenge is macromolecular complexity to analyze structure and composition of polysaccharides. The second challenge is microbial complexity, namely concerning their metabolic activity. The third challenge is integrating molecular and microbial complexity, by using multi-omics approach. Our approach provides a foundation for evaluation of systemic effects of environmental fluctuation, and a step for opening up a new window that will clear up metabolic dynamics in the ecosystem.
