Resilience of corals to hurricanes: a simulation model

This study tested how the frequency and intensity of hurricanes, and the size and growth rate of coral colonies influence the resilience of coral populations to disturbance by severe storms. A simulation modelling approach was used to examine the resilience of four coral species with differing life history characteristics: Agaricia agaricites, A. lamarcki, Helioseris cucullata, and Porites astreoides. Resilience, defined as the rate of area (coral cover) gain, was greater for three of the species when storms were less frequent or more intense. Resilience for all species increased with colony growth rates and with increasing proportion of small and medium-sized colonies. We conclude that (1) coral populations composed of intermediate-size, fast-growing colonies the most resilient following one or more storm disturbances, and (2) that resilience of anthropogenically stressed corals depends, in part, on population size structure.
