Synthesizing Larval Competence Dynamics And Reef-Scale Retention Reveals A High Potential For Self-Recruitment In Corals, Joana Figueiredo, Andrew H. Baird, Sean R. Connolly

Marine & Environmental Sciences Faculty Articles

Many organisms have a complex life-cycle in which dispersal occurs at the propagule stage. For marine environments, there is growing evidence that high levels of recruitment back to the natal population (self-recruitment) are common in many marine organisms. For fish, swimming behavior is frequently invoked as a key mechanism allowing high self-recruitment. For organisms with weak-swimming larvae, such as many marine invertebrates, the mechanisms behind self-recruitment are less clear. Here, we assessed whether the combination of passive retention of larvae due to re-circulation processes near reefs, and the dynamics of settlement competence, can produce the high levels of self-recruitment previously …
