Estimating dispersal of coral larvae for ecosystem management in Tioman island

Dispersal of coral larvae and successive recruitment are important for ecosystem man-agement especially in marine protected areas to estimate how far larvae travel in the water and settle on substrates. Information on dispersal distance is crucial to determine the magnitude of self-recruitment and i...
