Strengthening management measures necessitate understanding the variability of larval connectivity and bridging global OPEN ACCESS connectivity models to local scales. An individual-based Lagrangian biophysical model was Citation: Pata PR, Yñiguez AT (2019) Larval used to simulate connectivity between coral reefs for three organisms with different early life connectivity patterns of the North Indo-West history characteristics: a coral (Acropora millepora), a sea urchin (Tripneustes gratilla), and Pacific coral reefs.
