Networks in Microbial Ecology

In 2006, Raes and Bork introduced molecular ecosystem biology (Raes and Bork, 2008). Based on the amount of molecular data given by ‘omics’ methods, and particularly metagenomics (National Research Council Committee on Metagenomics and Functional, 2007), they suggest that molecular system biology should be considered at the ecosystem level by mixing metagenomics, metatranscriptomic and metabolomics data. By linking structure and function, we would be able to better understand ecosystem functioning. Over the past decade, few studies have linked taxonomical and functional data at the ecosystem level in an ecological network (Ruan et al., 2006; Fuhrman, 2009; Zhou et al., 2010; Mendes et al., 2014).  Ecological networks are defined at the scale of the microbiome as displaying similar patterns as other networks (e.g., computers, genes, human social networks), but they follow different rules as predation, competition and mutualism constrain them (Montoya et al., 2006).
