"Fontaine et al. (2003) have proposed that a substrate- induced succession of microorganisms from r- to K-strategist is responsible for this priming effect. In general, r-strategists (copio- trophs) dominate initially following amendment because they are able to maximise their growth rate on labile substrates. Later, the slow-growing K-strategists (oligotrophs) tend to dominate since they use resources more efficiently by degrading recalcitrant SOM  (Fontaine et al., 2003; Blagodatskaya et al., 2007). " \cite{Jenkins_2010}  " In addition, the analysis by phylogenetic and ecological groups, suggest that the communities respond in a similar trajectory of initial colonization first by heterotropic generalists and later specialists. "\cite{L_pez_Lozano_2013}  "Resource availability is also likely to be a funda- mental driver of microbial succession, but the limiting resources and environmental factors regulating succession will be more complex given the far greater physiological diversity contained within microbial communities and the breadth of environments in which succession can occur. During endoge- nous heterotrophic succession, labile substrates will be consumed first, supporting copiotrophic microbial taxa that are later replaced by more oligotrophic taxa that metabolize the remaining, more recalcitrant, organic C pools in the later stages of succession (Rui et al., 2009)."\cite{Fierer_2010}
