  abstract = {{T}he strong advective circulation governing western boundary current systems poses challenges to coastal organism to retain their planktonic larvae and assembly in local communities. {H}owever, instabilities around the predominant current, generating features such as eddies, may increase retention and thereby enhance local diversity. {H}ere, we have investigated this hypothesis through high-resolution (1/36 degrees) community-based {L}agrangian dispersal modelling experiments conducted along the {P}ernambuco {P}lateau and adjacent open ocean off {B}razil, which is part of the strong {A}tlantic {M}eridional {O}verturning {C}irculation. {I}n the highly advective north portion of the plateau, we found that retention is reduced and advection from open ocean is intense. {U}nder such circumstances, the assembly of local communities is likely driven by mass effect, which results in homogeneous communities with reduced biodiversity. {I}n contrast, in the south portion of the plateau, eddies and meanders associated with the interaction of the currents with the plateau topography and the seasonal variability of the {S}outh {E}quatorial {C}urrent bifurcation increase local retention and reduce advection from open ocean. {I}n such conditions, both, species sorting and mass effect assembling archetypes, likely drive the distinct and rich biodiversity inhabiting the region to the south of the plateau. {T}he dispersal patterns obtained from the {L}agrangian experiments align with the known spatial patterns of biodiversity distribution along the {T}ropical {S}outhwestern {A}tlantic and provide important insights for regions and taxa for which knowledge is limited or absent. {T}hese results also provide elements for the proper definition of biodiversity conservation and management strategies and for a better understanding of the processes regulating community assembly in highly advective systems around the globe.},
