  abstract = {{W}e investigate chloroplast {DNA} variation in a hyperdiverse community of tropical rainforest trees in {F}rench {G}uiana, focusing on patterns of intraspecific and interspecific variation. {W}e test whether a species genetic diversity is higher when it has congeners in the community with which it can exchange genes and if shared haplotypes are more frequent in genetically diverse species, as expected in the presence of introgression. {W}e sampled a total of 1,681 individual trees from 472 species corresponding to 198 genera and sequenced them at a noncoding chloroplast {DNA} fragment. {P}olymorphism was more frequent in species that have congeneric species in the study site than in those without congeners (30% vs. 12%). {M}oreover, more chloroplast haplotypes were shared with congeners in polymorphic species than in monomorphic ones (44% vs. 28%). {D}espite large heterogeneities caused by genus-specific behaviors in patterns of hybridization, these results suggest that the higher polymorphism in the presence of congeners is caused by local introgression rather than by incomplete lineage sorting. {O}ur findings suggest that introgression has the potential to drive intraspecific genetic diversity in species-rich tropical forests.},
