Coral connectivity in the southwest Indian Ocean

This dispersal network is based on SECoW simulations for Platygyra daedalea, a type of brain coral.

Click on a reef to see more information, or hover over a reef to see outbound larval connections. Line thicknesses are proportional to the strength of individual outbound connections, and circle size is proportional to out-strength.

Out-strength: the likelihood of virtual larvae settling anywhere.

In-strength: the ratio between incoming and outgoing virtual larvae.

Out-entropy: The diversity of larval destinations from a site.

In-entropy: The diversity of larval sources for a site.

Out-consistency: The proportion of spawning events accounting for half of outbound settling larvae.

In-consistency: The proportion of spawning events accounting for half of inbound settling larvae.

Reefs with high out-strength, out-entropy, and out-consistency may play an important role in maintaining regional reef resilience. Reefs with high in-strength, in-entropy, and in-consistency may have greater recovery potential.

This app is based on coral larval dispersal simulations run by researchers at the University of Oxford, led by Noam Vogt-Vincent, April Burt, and Helen Johnson (see here for the preprint), and was funded by the Natural Environment Research Council (NERC) and the Seychelles Conservation and Climate Adaptation Trust (SeyCCAT). This interactive web app was conceptualised by Noam Vogt-Vincent and Otis Brunner, and developed by Julia Janicki.
