  abstract = {{I}n mangrove ecosystems, strong reciprocal interactions exist between plant and substrate. {U}nder semi-arid climate, {R}hizophora spp. are usually predominant, colonizing the seashore, and {A}vicennia marina develops at the edge of salt-flats, which is the highest zone in the intertidal range. {A}long this zonation, distribution and speciation of {C}, {F}e, {S}, {N}, and {P} in sediments and pore-waters were investigated. {F}rom the land-side to the sea-side of the mangrove, sediments were characterized by {I}/ increase in: (i) water content; (ii) {TOC}; (iii) mangrove-derived {OM}; {II}/ and decrease in: (i) salinity; (ii) redox; (iii) p{H}; (iv) solid {F}e and solid {P}. {B}eneath {A}vicennia and {R}hizophora, {TS} accumulated at depth, probably as a result of reduction of iron oxides and sulfate. {T}he loss of total {F}e observed towards the sea-side may be related to sulfur oxidation and to more intense tidal flushing of dissolved components. {E}xcept the organic forms, dissolved {N} and {P} concentrations were very low beneath {A}vicennia and {R}hizophora stands, probably as a result of their uptake by the root systems. {H}owever, in the unvegetated salt-flat, {NH}4+ can accumulate in organic rich and anoxic layers. {T}his study shows: (i) the evolution of mangrove sediment biogeochemistry along the intertidal zone as a result of the different duration of tidal inundation and organic enrichment; and (ii) the strong links between the distribution and speciation of the different element},
