Abstract：
Traditional ecosystem models have parametarized microbes as a single black box that has “complete” functionality even with environmental changes. However, recent studies demonstrate the importance of biodiversity and community composition of microbes in determining their biogeochemical functions. In particular, we focus on the roles of interactions between microbes within microbial food web in maintaining high processes rates and its stability against environmental changes. I’m going to talk about a couple of models that focus on bacterial diversity and POC sinking flux in the oceans.
Recently, we also developed a new bioinformatics approach, linking whole genomic information of diverse microbes into complexity and multidimensionality of ecosystem functioning, can give an index to assess functional redundancy of ecosystem. Microcosm experiment using environmental microbes confirms the effectiveness of the index and supports the predicted low functional redundancy of microbial ecosystem, demonstrating that initial species and gene loss (e.g. 5%) causes a detectable reduction of multiple ecosystem functions. The proposed index serves as a scientific basis to determine an acceptable level of species loss for sustainable use of ecosystem services.
