  abstract = {{T}he functional patterns of microbial communities (microbial respiration, enzyme activities, functional diversity) and the relevant physico-chemical characteristics of rhizospheric soils were studied during the process of mudflat colonization by mangrove. {T}he study site is a fringe mangrove stand located in {M}ontabo {B}ay at {C}ayenne ({F}rench {G}uiana). {I}t is characterized by different vegetation development stages dominated by an assemblage of {A}vicennia germinans and {L}aguncularia racemosa. {R}hizospheric and surface soils were collected from three stations based on successional stages of mangrove colonization: pioneer ({P}), coppice ({C}), and young forest ({F}). {T}he microbial functional patterns showed significant progressive shifts along the mangrove vegetation profile. {T}he {P} stages, those most influenced by tide currents, were macroscopically characterized by hydro-sedimentary instability and micro-phytobenthic colonization of mudflat. {T}his stage, characterized by low total organic carbon ({TOC}) content and quality, showed the lowest extracellular enzymatic activities and the highest functional metabolic diversities. {TOC} quality analyses by {C}-13 {CPMAS} {NMR} provided evidence of progressive {TOC} enrichment and an increasing imprint of aboveground vegetation on {C} quality as succession occurs. {T}hese differences in the origin, amount, and quality of soil organic matter ({SOM}) of older stages exerted both a quantitative and qualitative control over microbial functional responses. {T}his indicated the enhancement of aboveground-belowground functional linkages, leading to the expression of high decomposition activities and a functional loss and specialization of rhizospheric microbial communities.},
