Summary
We review the evidence for source–sink dynamics in marine and estuarine species ranging from algae and seagrasses to invertebrates and vertebrates. There are only a few species with strong evidence for source–sink dynamics, primarily due to the logistical difficulties inherent in demonstrating source–sink dynamics convincingly, but there is extensive circumstantial evidence for the existence of source–sink dynamics, indicating that the issue requires serious consideration and further examination. The most prevalent mechanisms underlying source–sink dynamics include variation in habitat quality (natural or anthropogenic), dispersal, predation, and fishery exploitation, as well as interactions between these factors. In efforts to conserve or restore marine and estuarine metapopulations, optimal results are most likely to be achieved by identifying the connectivity between populations and preserving source populations or interconnected networks of sources and sinks. Further investigation of source–sink dynamics is critically needed to promote the effective conservation and restoration of marine and estuarine species.
