  abstract = {{W}ithin tree communities, the differential use of soil {N} mineral resources, a key factor in ecosystem functioning, may reflect functional complementarity, a major mechanism that could explain species coexistence in tropical rainforests. {E}perua falcata and {D}icorynia guianensis, two abundant species cooccurring in rainforests of {F}rench {G}uiana, were chosen as representative of two functional groups with complementary {N} uptake strategies (contrasting leaf δ15{N} signatures related to the δ15{N} of their soil {N} source, or ). {T}he objectives were to investigate if these strategies occurred under contrasted soil {N} resources in sites with distinct geological substrates representative of the coastal rainforests. {R}esults showed that species displayed contrasting leaf δ15{N} signatures on both substrates, confirming their complementary {N} uptake strategy. {C}onsequently, their leaf 15{N} can be used to trace the presence of inorganic {N}-forms in soils ( and ) and thus to indicate the capacity of soils to provide each of these two {N} sources to the plant community.},
