Abstract: Population viability analyses are common in conservation and management strategies; however, accurately gauging the reproductive output of scleractinian corals can be challenging. A simulation model of synchronous broadcast spawning events was built to investigate (1) the scales of distance at which reproductive contact becomes unlikely between individual coral colonies, and (2) the relationship between colony density and fertilization success. Fertilization was found to be unlikely between simulated coral colonies more than 30 to 40 m apart in the conditions tested. Fertilization rates exhibited a logarithmic relationship with colony density in the range of colony densities simulated that indicated the presence of a strong Allee effect. The influence of intercolonial distance on fertilization success suggests that some measure of spatial distribution should be included in conjunction with colony density when monitoring reef health and both factors should be considered when determining colony transplantation strategies for conservation.
