Table 1 Summary of the species-specific responses to crustose red algal-associated settlement inducers reported previously and tested here.

From: Settlement of larvae from four families of corals in response to a crustose coralline alga and its biochemical morphogens

  1. Algae include crustose coralline algae, branching coralline algae* and crustose red algae#. The “ + ” and “−” symbols and their associated colors represent the strength of the settlement response, where known: “ ++ ” > 50% (green), “ + ” 10–50% (yellow), “−” < 10% (red). n/a indicates treatments that were not tested. Refer to Table 2 for complete results of this study.
