“…Microorganisms play crucial roles in biogeochemical cycles that cannot be achieved by individual species or populations due to their simple structures and functions (Jousset et al ., ; Momeni et al ., ; Nadell et al ., ; Zelezniak et al ., ). In reality, various functional microorganisms interact and cooperate closely to form complicated networks in an ecosystem, which are the foundation of community construction and succession (Bell et al ., ; Singh et al ., ; Franzosa et al ., ; Battin et al ., ; Zeglin et al ., ). Although phylogenetic diversity and species interactions have been investigated extensively, generally using 16S rDNA as the molecular marker (Jansson and Taş, ; Lievens et al ., ; Ghoul and Mitri, ; Nadell et al ., ), and a handful of models have been developed based on the biotransformation of simple compounds to evaluate how abiotic and biotic factors shape microbial community structure and function (Lawrence et al ., ; Allison, ; Sulman et al ., ), our knowledge about microbial ecosystems is still in its infancy, especially in revealing community assembly and succession patterns in a specific habitat and reframing theoretical frameworks of microbial ecology (Buchkowski et al ., ).…”
