  abstract = {{D}ue to the relative geographical isolation of {R}eunion {I}sland the grouper {E}pinephelus merra is assumed to be self-recruited but almost nothing is known about its larval history. {W}e used elemental composition of the otoliths ({B}a, {S}r, {M}n, {M}g, {N}a) of fifty-eight one year-old groupers collected from four main coral reefs on the west coast of {R}eunion {I}sland, to determine environmental variations during their early life history. {H}ierarchical clustering analysis of the otolith chemical composition of core and early larval phase, allowed the identification of three groups of larvae. {L}arvae from the first group (cluster 1) were born and dispersed in {B}a-enriched water bodies, while the second and third groups included larvae that had crossed {B}a-poor water masses. {L}arvae of group 1 were primarily found in the southern sector (74%) decreasing northward, while group 3 were more abundant in the northern sector (56%) and cluster 2 showed a scattered distribution. {S}uch opposite spatial distributions might suggest that clusters 1 and 3 originated from opposite dispersal kernels, south and north respectively. {I}t is possible however that larvae from both groups came from the same spawning ground but represented different cohorts that experienced changing geochemical conditions either at the spawning site or within the surrounding pelagic environment, over the course of the breeding season. {B}oth scenarios on the origin and dispersion may thus suggest significant influence of hydrographic features causing or preventing larvae from becoming displaced far from their natal area.},
