“…Because eggs and larvae are tiny propagules spawned in large numbers, it is near impossible to study and quantify their dispersal in situ (Levin, 2006). Some studies used geochemical trace elements in otoliths (Almany et al, 2007), genetic markers (Randon et al, 2021) or tracked drifters (Vendrami et al, 2021) to understand hydrodynamics and larvae transport. However, they are financially costly and only provide local insights of dispersal for a given time period and at a local scale.…”
